One of the other powerful features of Spring is the support of external configurations which can be passed to an application in several ways, e.g. as command-line arguments, specified in properties or YAML files or as system properties. In this section, we focus on adding a configuration option as application start argument using STS. This is illustrated by configuring Tomcat to start on a different port.
In order to run an application on a Tomcat port other than the default, you may use the command below, where a custom port is specified as command-line argument:
When using STS, you have go to the run menu. Select run configurations… from the Run Configurations dialog, select Spring Boot App from the left panel and select demo – DemoApplication (this will be different if you did not select the default project). From (x)= Arguments tab type in the Program Arguments window
--server.port=7070
and run. You should see output in your console similar to the output that is shown below:
.
.
2016-07-06 13:51:40.999 INFO 8724 --- [ main] s.b.c.e.t.TomcatEmbeddedServletContainer : Tomcat started on port(s): 7070 (http)
2016-07-06 13:51:41.006 INFO 8724 --- [ main] com.baeldung.boot.DemoApplication : Started DemoApplication in 6.245 seconds (JVM running for 7.34)
Working with properties
Spring Boot does a lot of things automatically for you. But that doesn’t mean you can’t customize this default behavior. One way to customize the behavior is in code, the other one is by using properties. And Spring Boot offers a huge number of properties.
Assuming you want to define the port your Spring Boot app is running on. Just open the “application.properties” or “application.yml” file (depending on whether you prefer property or YAML format for your config files) and go. The Spring Tools for Eclipse IDE provide an enhanced editor experience that offers code completion for all the available Spring Boot properties.
Beyond the code completion, which offers a full list of properties together with documentation hints and types of those properties, the editor also checks keys and values for correctness. If, for example, a property is unknown, it will let you know via a warning. If the value that you put in doesn’t match the type of the property, an error will appear.

STS Main Features
STS is an Eclipse-based development environment that is customized for the development of Spring applications.
It provides a ready-to-use environment to implement, debug, run and deploy your applications. It also includes integration for Pivotal tc Server, Pivotal Cloud Foundry, Git, Maven and AspectJ. STS is built as an addition on top of the latest Eclipse releases.
2.Project Configuration
STS understands almost all of the most common Java project structures. It parses configuration files and then displays detailed information about beans that are defined, dependencies, used namespaces and in addition extracts overviews for certain stereotypes.
2.STS Features Overview
Eclipse STS validates your project and provides quick fixes for your applications. For example, when working with Spring Data JPA, the IDE may be used to validate query method names (more on this in section 6).
STS also provides a graphical view on all bean methods and their mutual relationships. You may want to have a closer look at the graphical editors that come with STS by looking into the views that are available under the menus window, show view and then Spring respectively.
STS also offers other additional useful features that are not limited to Spring applications only. The reader is recommended to a look at the full list of features that can be found here.
Spring Tool Suite Download
Step 1: Go to their website and in Spring Tools 4 for the Eclipse section in order to download. choose your corresponding file according to your OS.

Eclipse IDE : How to add Spring Tool Suite (STS) plugin to Eclipse?
Cài đặt Spring Tool Suite Cho Eclipse.
Các bạn cũng có thể download sẵn bản IDE Spring Tool Suite base trên Eclipse tại: https://spring.io/tools/sts/all
Nó có sẵn các phiên bản cho Window, Linux hay Mac
Ở đây mình sẽ cài Spring tool suite vào eclipse, bản Eclipse mình sử dụng là Neon.3 Release (4.6.3)
– Truy cập Eclipse Marketplace
– Gõ sts hoặc Spring tool để tìm kiếm Spring Tool > Click Install
– Chọn Confirm
– Chọn Accept > Finish
– Hiển thị các tính năng của Spring: Window > Perspect > Open Perspect > Other > Spring
– Sau khi chọn hiển thị, các bạn sẽ thấy biểu tượng Spring ở góc phải của Eclipse
Spring Tool Suite (STS) provides the development environment for Spring-powered enterprise applications. This can be easily downloaded from the Eclipse marketplace in the following manner:
Within the Eclipse IDE, click on Help | Eclipse Marketplace… and search for Spring STS by submitting Spring STS in the Find text field. The search result would show up different versions of STS for different Eclipse versions.
Choose the appropriate version and install. The most current version is 3.9.0.RELEASE.
Restart Eclipse, and you are all set to create your first Spring Boot web application.

Logging and ANSI Console
When you run the project from the IDE using the run command, you will notice that the console outputs some nice color-coded log statements. In case you want to turn it off, go to run configurations… and disable the check box Enable ANSI console output on the Spring Boot tab. Alternatively you can also disable it by setting a properties value in the application.properties file.
spring.output.ansi.enabled=NEVER
More information on the configuration of your application logs may be found here.
Running Spring Boot apps
Suppose we have a simple Spring Boot application that we got from importing the “Rest Service” guide. It implements a simple @RestController and serves some JSON back to the user. In order to run this app, you could select “Run As → Spring Boot App” or create your own launch configuration in the Eclipse IDE. A better and easier way to run your Spring app is the Spring Boot Dashboard. It is a separate view in your IDE that you can activate from the toolbar (look for the Spring Boot icon).
The Spring Boot Dashboard lists all the projects from your workspace that are Spring Boot projects. You can select one or multiple projects and run them just by hitting the “(Re)Start” button. It will create a default launch config for your Spring Boot app automatically if you don’t have one yet.
The Spring Boot Dashboard helps you to deal with potentially many Spring Boot apps in your workspace. It allows you to filter them, start or even restart multiple apps in parallel, or easily jump to the right console view for a running app.
The Spring Boot Dashboard, in addition to managing the launching of apps, offers more facilities for gaining insights into your applications. Jumping to the properties view from a running and selected Spring Boot app in the dashboard, you will see not just a quick overview and a ready-to-use hyperlink that lets you jump to the frontend of the running app immediately (without looking up port numbers, etc.). You will also see two additional tabs that provide direct information from the running app: request mappings and beans. The request mappings tab, for example, shows you all the request mappings that the application serves together with its location in the source code. Double-clicks let you jump directly to the source code where the mapping is implemented. This allows you to easily navigate between your running app and your source code.
The beans tab offers you the list of beans that are live at runtime, created by the Spring application. You can browse through the list or filter for certain characters. The good thing here is that you can also see dependencies among those beans, so that you can gain insight into which bean depends on which other bean. You want to know, for example, which data source got injected into your controller? Search for your controller name in the list of live beans and you will see the answer right away.

The error message complains about missing test bundles, which you don’t need when installing the Spring Tools into an existing Eclipse installation. You should select the features under the `Spring Tools` category only, that is all you need. And those features don’t require the mentioned test bundles. If that doesn’t help, please provide more details how you are trying to install the Spring Tools and what you select along the way.

This looks like a network glitch when downloading the artifacts or a proxy server getting into the way. Please try again. If this doesn’t help, some cache might be causing this broken file to stick around, so please search for the files with those names “org.springframework.ide.eclipse.docker.client” and “org.springframework.tooling.boot.ls” and delete them from the cache. Hope that helps!

In reply to Got error when installating progress. by Joe Hsu
It looks like you are using an updated Eclipse version (2021-03) here, for which the latest versions of the Spring Tools 4 (on the Eclipse Marketplace) are no longer compatible with. Therefore, you are running into an issue, most likely the installation process tries to install components from a newer Eclipse platform version (alongside the Spring Tools components) that use a newer signing infrastructure – which then results in the above mentioned error.
The best solution here would be to use a more recent Eclipse platform (2022-09 at the time) and install the Spring Tools 4 on top of that Eclipse – or grab the latest ready-to-use distribution from https://spring.io/tools.
If you have to use the 2021-03 Eclipse (for whatever reason), you can install an old version of the Spring Tools 4 using the “Install New Software” menu item and then this update repository: https://download.springsource.com/release/TOOLS/sts4/update/4.12.0.RELE…
It will give you the latest version of the Spring Tools 4 that was compatible with that version of Eclipse – but it is an outdated and no longer supported version, so I don’t recommend this option and would strongly recommend to use the latest version instead – if at all possible.
x509 certificate issue?
Submitted by Walter L on Sat, 09/24/2022 – 15:55
Just downloaded a fresh install of Eclipse Version: 2022-09 (4.25.0) – Build id: 20220908-1902, and fired up Marketplace to install Spring Tools 4 (4.16.0.RELEASE). I only kept the two required components and clicked on Install. As it’s downloading, a “Trust” dialog popped up asking me to trust the expired certificates from Pivotal – the expiration dates were 2018 and 2020. Google search turned up nothing. Can I continue installation without trusting the expired certificates?

In reply to Error while installing Spring tool by Agumamidi Manvitha
This is usually caused by some stale cache data. You can fix this by going to the Preferenes -> Install/Update -> Available Update Sites, then select the one you mentioned, and press “Reload”. This usually solves the problem.
In case this doesn’t help, delete the entry from the list of available update sites, restart the IDE, and add the entry back to the list. That should work as a last resort if everything else failed.

Thak you Martin. However, that stackoverlow did not help. I saw that post before I asked here and I followed it again. While I have been able to add certificate as described (making below assumptions as the explanation was not clear on that), I am still unable to install STS4 into my Eclipse 2021-03.
Following the SO link you provided:
I navigated in Chrome to https://marketplace.eclipse.org/content/spring-tools-4-aka-spring-tool-… – I assume this is where I should be to export the certificate
Following Stackoverflow link, I exported the certificate and used keytool to add it to my jdk1.8/jre/lib/security/cacerts
I even confirmed it has been added, also using keytool to list certificates
Restarted my machine, restart Eclipse > Help > Market place > search for “STS” > Select STS4 > Install
Got box listing what will be installed > Confirm
My C:/Program Files/Java has two versions jdk 1.8.0_172 and jdk-11.0.10. I did the above for jdk 1.8.0_172 as that is the jdk in my System Path variable.

The “add starters” menu option is indeed gone (since a few releases already), but I got replaced with a new “Add Starters” menu item that you should be, which also allows you to add starter modules from start.spring.io and even brings more goodies from start.spring.io into the IDE here, e.g. additional resources that start.spring.io would generate for you, new properties in your properties file (in case the selected modules include them), etc. Here is a user guide for this new way to add starters to your project: https://github.com/spring-projects/sts4/wiki/Add-Spring-Boot-Starters-T…
Hope that helps and that you like the new wizard!!!

Hello Martin,Thank you for your answer.Yes I know this procedure which you mentioned in the web link.But I’m sorry, I prefer the old method with the ‘Edit starters’ option …When we choose ‘Add starters’, why in the graphical interface, you don’t add an ‘already selected’ section in addition to the ‘selected’ section?I think it’s important to quickly have a graphic visual, rather than making a comparison with the xml file …The 2 ways can be complementary …Maybe it’s hard to implement the code to be able to do this? ^^

Hey Richard,
your feedback on this is much appreciated. The reason why we no longer do something like a “pre-selection” is starter modules that you already have on your project is based on the latest generations of the initializr project and the way that works. When you select starter modules in there, the resulting project might not exactly contain those modules exclusively. There is logic in initializr and some of the starter modules to do more sophisticated things, like automatically adding additional other starters for you. And there is no “inverted logic” in there, which infers which starters you would need to select in order to produce the set of starters that you have. Therefore we don’t really have a way to implement this “inverted logic”. (This gets even more complicated if users edited their pom.xml file (in case you use Maven) manually). Therefore we decided to not implement any logic to pre-select existing starters on your project. Sorry for not being able to bring this pre-selection back. Hope you find the new wizard useful nevertheless. If you have additional suggestions, please raise them as enhancement requests here: https://github.com/spring-projects/sts4/issues.

In reply to Re: Re: Re: Re: Hello, by Richard Dutellier
Actually, identifying dependencies of a project is not that complicated in an IDE, since the Maven integration for Eclipse in this case already does that work for you – and that is what the pom dependency analyzer tool would do as well in case I understood this. The difficult part is to calculate the pre-selection on start.spring.io that would lead to the pom that you analyze. It is not a 1-to-1 mapping (for a good reason actually, from the project-generation perspective).

Hey! That sounds like an issue with the installation and the underlying bundles being maybe wired in a weird way. The best way forward would be a submit an issue at https://github.com/spring-projects/sts4/issues and tell us exactly which package of Eclipse 2021-03 you installed, which other third-party plugins you added, and how you installed the STS4 components then. I used the Eclipse JEE paclage of 2021-03 and installed STS4 from the Eclipse marketplace and that seemed to work, so we need to take a closer look at your exact setting in which you are trying to install the Spring Tools 4.
As a quick fix for you, feel free to download a ready-to-use distribution of the Spring Tools 4 for Eclipse from https://spring.io/tools. Version 4.10.0 of the Spring Tools 4 for Eclipse are a distribution built on Eclipse 2021-03, so you will get the latest in here as well.

If you want to install Spring Tools 4 into an existing Eclipse installation, you can choose the “Eclipse Marketplace…” menu entry, then search for Spring, pick the “Spring Tools 4” entry, and press the “Install” button.
The JAR file that you can download from the https://spring.io/tools page is a self-extracting full distribution of the Spring Tools 4 for Eclipse (including an Eclipse 2020-12 with pre-installed Spring Tools 4 extensions). You can download the JAR and double-click it. It will then self-extract the full distribution.

From the brief description it sounds like an installation issue or an incompatibility from under the hood somewhere. I would recommend to file an issue at https://github.com/spring-projects/sts4/issues/ and provide some detais (maybe a few steps to reproduce), and we can continue from there to find out what is going wrong there.
If you are not tied to Eclipse 2020-06, I could also recommend to download a ready-to-use distribution of the latest Eclipse release (2020-12) with all the Spring Tools 4 pre-installed from https://spring.io/tools.

That sounds indeed bad. Can you pleaee file a bug at https://github.com/spring-projects/sts4/issues/ for this and tell us how to reproduce this crash? Is it really the JVM that is crashing or is it a freeze at the UI, so that the process isn’t responding anymore? Is there something in the Error Log View that relates to the problem? Or is the VM itsel crashing and in case that happens, is there a JVM crash log file tha you could attach? In case the process freezes, there is a setting in the “Preferences -> General -> UI Responsiveness Monitoring” that you could turn on to capture stack traces while the UI seems to be frozen. That would be great and help us a lot to find the underlying issues.

This is part of some default options to speed up the exeution and launch of the Spring Boot app, but you can change that in the “Preferences -> Spring -> Boot”, take a look at the “Fast Startup” section, where you can change those settings.

Thanks your answer, I found the place and remove the option. However, still not working with another error when I run the application…. seems it’s stil a problem of JDK. I have synchronized all configuration place in eclipse with JDK1.7.0 (such as project compiler,classpath settings, eclipse preferences etc). Spring boot version I use is 1.5.9 Release.
The error is “Could not find the main class”. then I copy the command and run in the dos window, it says that:”Exception in thread “main” java.lang.UnsupportedClassVersionError: cn/com/MainApplication : Unsupported major.minor version 51.0″. I know the 51.0 means the version jdk1.7, but I am using JDK1.7.
Could you give some advice? Does STS4 support JDk1.7?

In reply to Re: Re: Error “Unrecognized VM option ‘TieredStopAtLevel=1′” by James Balaji
STS4 in general supports implementing and running applications on top of a JDK7. You need to configure the JDK7 runtime environment in the preferences (as you probably did) and select it as the default for the JavaSE7 execution environment. Make sure it appears correctly as the entry in your project classpath containers in the packag explorer.
In addition to that you need to make sure to compile your project on a Java7 level by setting the compiler level in the Java compiler preferences for your project.
Then in the launch configuration, you should make sure that the JDK7 is used to launch the app. This “could not find main class” is usually related to some misconfigured JRE settings in the areas described above.
Hope this helps!

This problem is a bit complicated to analyze remotely, since it is not totally clear where this comes from. Here is what you could do to solve this:
go to the “Preferences -> Install/Update -> Available Update Sites”, select the one for the Spring Tools 4 and press “Reload”. Maybe that solves the problem already.
If not, remove that update site from the preferences and restart your IDE. Then try the install again.
If all that doesn’t help, try to install the feautes manually, as described here: https://github.com/spring-projects/sts4/wiki/Installation#install-sprin…

Sorry for the late answer, somehow missed the question here. You could analyze the underlying issue by opening up the console, opne an OSGi Host Console, and type in “ss” for “short status”. If there is anything showing up as “INSTALLED”, something went wrong with regards to the dependency resolution of bundles. This is hard to debug and to solve. In that case, I would recommend to download a ready-to-use distribution from https://spring.io/tools and go from there. If the list of bundles shows up fine (nothing in the “INSTALLED” state), then the wizard to create a new project using Initializr (e.g.) should show up (“Spring Starter Project”) in a “Spring” category.

Spring Tools for Eclipse IDE
To make it even easier to write modern Spring Boot applications, the latest generation of the Spring Tools for the Eclipse IDE are well suited for getting started with Spring Boot and working on large microservice applications that are based on Spring Boot. This article walks you through the most important features of the tooling and provides great insight into a number of tips and tricks along the way.
Spring Boot on Eclipse | How to install Spring Tools Plugin [STS] in Eclipse | Spring Boot Tutorial
Spring Tools 4
Spring Tools 4 is the next generation of Spring tooling for your favorite coding enrivonment. Largely rebuilt from scratch, it provides world-class support for developing Spring-Boot-based enterprise applications, whether you prefer Eclipse, Visual Studio Code, or Eclipse Theia.
Getting Started
Spring Tool Suite 4 makes it easy to get started. A direct and easy-to-use integration of the Spring Initializr and the famous Spring Guides allows you to go from nothing to a running Spring Boot app in seconds.
Navigate your Spring code at the speed of light
Understanding and quickly navigating source code is essential for coding. The new Spring Tools 4 understands your Spring-Boot-based source code and allows you to quickly get an overview and navigate to the important pieces of your Spring apps. Finding Spring elements and navigating to them has never been easier.
Smart Code Editing
Code completion is a critical part of working with source code. The all-new Spring Tools 4 provides smart code completions for the Spring elements in your app.
Runtime Information In Your Editor
Spring Tools 4 now bridges the gap between your source code and running Spring Boot applications. By taking advantage of the Spring Boot Actuators, we enriched the source code with detailed information from the running app (e.g., exact bean wiring information, conditional reports, configuration, details, and more).
Categories: IDE
Tags: spring, Spring IDE, Cloud, Spring Tool Suite, STS, LSP
The aforementioned application may be started by right-clicking on the project and selecting run as Spring Boot App. Without STS, you will most likely run the application from the command-line with the following command:
$ mvn spring-boot:run
By default Spring applications are started with Tomcat running on port 8080. At this point, the application starts on port 8080 and basically does nothing else as we did not implement any code yet. Section 8 shows you how to change the default port.

Spring Tools 4
Tailored for developing enterprise applications using Spring Framework and Spring Boot, the new generation of Spring Tools provides world-class development support for your Spring applications. Our tools have deep knowledge of Spring built in.
The all-new Spring Tools can be used in various coding environments, ranging from Eclipse as a full-featured integrated development environment to Visual Studio Code and Theia as lightweight code editors. Continue to use your preferred environment and add great Spring tooling to it.
The new generation of Spring Tools is largely built from scratch, incorporating modern technologies and developer tooling architectures. It runs in separate processes, is built with performance in mind from the start, and knows about the latest Spring technologies.
Spring Tool Suite 4 makes it easy to get started. A direct and easy-to-use integration of the Spring Initializr and the famous Spring Guides allows you to go from nothing to a running Spring Boot app in seconds.
Understanding and quickly navigating source code is essential for coding. The new Spring Tools 4 understands your Spring-based source code and allows you to quickly get an overview and navigate to the important pieces of your Spring apps. Finding Spring elements and navigating to them has never been easier.
Code completion is a critical part of working with source code. The all-new Spring Tools 4 provides smart code completions for the Spring elements in your app.
Spring Tools 4 now bridges the gap between your source code and running Spring Boot applications. By taking advantage of the Spring Boot Actuators, we enriched the source code with detailed information from the running app (e.g., exact bean wiring information, conditional reports, configuration, details, and more).
Version 3 of the Spring Tool Suite is no longer under active development and does not receive any maintenance updates anymore. The last and final release can be found on the Spring Tool Suite 3 wiki, alongside details of how to upgrade to Spring Tools 4.
Spring Tools for Eclipse IDE
Spring Tools 4: The new generation on the horizon
In the final section of this article, I want to give you a brief outlook at what is coming next. In December 2017 we launched the public beta of the next generation of Spring tooling. The so-called “Spring Tools 4” initiative and the corresponding public beta launch not just offers great tooling for Spring apps when working with the Eclipse IDE, but is also available for Visual Studio Code and Atom: https://spring.io/tools4.
The next generation includes all of what you have seen here in this article so far, and goes beyond that. It offers a super quick and easy source-code navigation to all the important pieces of your Spring Boot application. You will get easy access to all your request mappings, bean definitions, function implementations, data repositories, and more – just by selecting the “Go To Symbol” action.
In addition to that, your source code will be augmented with information from running Spring Boot applications. As soon as you start your Spring Boot app, real-time information from that app will appear in your source code, allowing you to get a unique insight into your running Spring Boot app. You will be able to see which beans are active, how they got wired to each other, which conditions have succeeded or failed and for what reason, and more.
Wanna give it a try? Feel free to take a look at: https://spring.io/tools4 – download and go! It is available as a ready-to-use Eclipse distribution (based on Eclipse Photon), and as extensions for Visual Studio Code, and Atom.
And feedback is always welcome. Please feel free to go to https://github.com/spring-projects/sts4/issues and raise questions, provide feedback, and report bugs and enhancement requests.

Let us start by bootstrapping a simple application. Without STS a Spring application is usually created by using the Spring Initializer website or the Spring Boot CLI. This may be simplified by clicking on Create Spring Starter Project from your dashboard in STS.
In the New Spring Starter Project screen either use the defaults or make your own adjustments and then go to next screen. Select Web and click finish. Your pom.xml should now look similar to this:
org.springframework.boot
spring-boot-starter-parent
2.4.0
UTF-8
1.8
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-test
test
Your version of Spring Boot may be different but the latest version may always be found here.

Installation
You can install the Spring Tools for Eclipse IDE into an existing Eclipse installation using the Eclipse Marketplace. Just open the marketplace client in Eclipse, search for Spring Tools and install the “Spring Tools (aka Spring IDE and Spring Tool Suite)” entry.
In case you prefer to use a ready-to-use distribution, you can go to https://spring.io/tools and download the Spring Tool Suite distribution, which is a full Eclipse distribution (based on the latest Eclipse release) with Spring Tools pre-installed.
JPA Query Name Checks
At times implementing a data access layer may be a cumbersome activity. A lot of boilerplate code may have to be written to realize simple queries and perform pagination. Spring Data JPA (JPA) aims to significantly facilitate such an implementation of data access layers. This section illustrates some of the benefits of using JPA in conjunction with STS.
To get started, add the following dependency for JPA to the previously generated pom.xml:
org.springframework.boot
spring-boot-starter-data-jpa
com.h2database
h2
You may have noticed that version has not been specified in the above declaration. This is due to the fact that dependencies are managed by the spring-boot-starter-parent.
To make JPA work, it is required that you properly define your entity managers and transaction managers. However, Spring auto-configures these for you. The only thing left to the developer is to create the actual entity classes. These entities are managed by the entity manager, which in turn is created by the container. Let us for example create an entity class Foo like so:
@Entity
public class Foo implements Serializable {
@Id
@GeneratedValue
private Integer id;
private String name;
// Standard getters and setters
}
The container scans all classes annotated with @Entity from the root of the configuration package. Next we create a JPA repository for the Foo entity:
public interface FooRepository extends JpaRepository
{
public Foo findByNames(String name);
}
At this point you may have noticed already that the IDE now flags this query method with an exception:
Invalid derived query! No property names found for type Foo!
This is of course due to the fact that we have accidentally written an ‘s’ in the method name of the JPA repository. To fix this remove the spurious ‘s’ like so:
public Foo findByName(String name);
Notice that no @EnableJpaRepositories was used on the config class. This is because the container’s AutoConfigration pre-registers one for the project.

Jar Type Search
“Jar Type Search” is a feature that was introduced in STS 3.5.0. It provides content-assisted proposals in projects for classes that are not (yet) on the classpath. STS may help you adding dependencies to your POM file in case they are not yet on the classpath.
For example, let us add a line to the Foo entity class. For this example to work properly, please ensure first that the import statement for java.util.List is already present. Now we may add Google Guava as follows:
private List
strings = Lists // ctrl + SPACE to get code completion
The IDE will suggest several dependencies to be added to the classpath. Add the dependency from com.google.common.collect, press return and add the dependency from Guava. The Guava jar will now automatically be added to your pom.xml file like so:
com.google.guava
guava
31.0.1-jre
As of version STS 3.8.0, you get a confirmation dialog box before STS makes its changes to your pom.xml.
Importing a Getting Started guide
With STS up and running, open the Import Spring Getting Started Content wizard from the File menu.
A pop-up wizard will offer you the chance to search and pick any of the published guides from the Spring website. You can either skim the list, or enter search words to instantly filter the options.]
The criteria is applied to both the title and the description when offering instant search results. Wildcards are supported.
You can also decide whether to grab the initial code set, complete code set, or both. For most projects, the initial code set is an empty project, making it possible for you to copy-and-paste your way through a guide. The complete code set is all the code from the guide already entered. If you grab both, you can compare your work against the guide’s and see the differences.
Finally, you can have STS open a browser tab to the guide on the website. This will let you work through a guide without having to leave STS.
For the purpose of this guide, enter rest into the instant search box. Then pick Consuming Rest. Pick Maven for building, and initial and complete code sets. Also opt to open the web page as shown below:
STS will create two new projects in your workspace, import the Consuming Rest code base (both initial and complete), and open a browser tab inside STS as shown below:
From here, you can walk through the guide and navigate to the code files.

Deploying to Cloud Foundry
Last, but not least, the Spring Boot Dashboard provides a direct integration with Cloud Foundry runtimes. In the same way as your local boot apps, a Cloud Foundry section in your dashboard will list the deployed and running apps, allows you to start and stop them. It also offers you to deploy your project via drag&drop to the Cloud Foundry instance and even debug a running app on Cloud Foundry.
Conclusion
In this article we have shown the basics of developing a Spring project in STS. Some of the things we have shown are execution of applications in STS, support during the development of Spring Data JPA and the usage of command-line arguments. However, there are many more useful features that may be employed during development as STS offers a rich set of features.
The full implementation of this article can be found in the github project – this is an Eclipse based project, so it should be easy to import and run as it is.

Using Spring Guides
In case you want to learn about a specific area of Spring and Spring Boot, you might want to take a look at the Spring Guides: https://spring.io/guides. They offer a comprehensive set of small tutorial-like step-by-step introductions to specific features of Spring. You can use them, for example, to learn how to implement your first RESTful service that delivers JSON.
Those guides can be imported into your Spring-Tools-enhanced Eclipse IDE by using the “Import Spring Getting Started Content” wizard, also available from the “New” menu. It is a great way to quickly import those guide projects, try them out, and learn from them.
Spring is everywhere
Spring is everywhere. It is at the heart of most modern business applications, in the center of modern cloud-based microservice applications, and used by millions of developers around the globe. And Spring Boot is at the heart of the current renaissance of Spring, making it easy, convenient, and extremely efficient to implement applications and services on top of Java.

Creating Spring Boot projects from scratch
The most famous way to create new Spring Boot projects is to go to https://start.spring.io and choose which Spring starter modules you wanna use. Once you do that, you can download a ZIP file of your new project and import that into your development environment.
The Spring Tools for Eclipse IDE come with a direct integration of that into your Eclipse IDE. Go to “File”, select “New” and choose the “Spring → Spring Starter Project”. The wizard lets you choose the Spring Initializr endpoint you would like to use (in case you have a custom one running within your company, for example) and then lets you select a boot version and offers all the Spring Boot starter modules that are around for that boot version. Just choose the ones that match your interest and click “Finish”. You end up with a ready-to-use Spring Boot project in your workspace – in just a few seconds.
Overview
This article illustrates some of the useful features of the Eclipse Spring Tool Suite (STS) IDE, which are useful when developing Spring applications.
First we show the benefits of using STS as compared to the traditional way of building applications with Eclipse.
Thereafter, we focus on how to bootstrap an application, how to run it and how to add additional dependencies. Finally we conclude by adding application arguments.
