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.

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.

Eclipse for JavaEE 2021-03 – Attempt to install STS failing

4. Hit Confirm button
5. Get error:

I read few of your answers on here, none of which helped.

I tried also placing the above URL (with https and http) in Install New Software and that failed with

Also tried installing STS4 IDE which worked fine but it keeps removing my Websphere Liberty node from Define New Server dialog when I right click in Servers tab > New Server > IBM > Websphere Liberty, so that is useless as well.

Note, the above urls have removed “://” because this site does not allow comments with extermal urls, also not helpful at all.

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:

1. 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
2. Following Stackoverflow link, I exported the certificate and used keytool to add it to my jdk1.8/jre/lib/security/cacerts
3. I even confirmed it has been added, also using keytool to list certificates
4. Restarted my machine, restart Eclipse > Help > Market place > search for “STS” > Select STS4 > Install
5. Got box listing what will be installed > Confirm
6. 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.

And ended up with the same error as described in my original question

Hey! 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…

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? ^^

In reply to Re: Re: Hello, by Richard Dutellier

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.

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).

SpringBoot wizard not showing on Eclipse 2021-03

Hi, I recently downloaded Eclipse 2021-03, and installed STS4, but upon attempting to run a spring boot app, or even creating a new one, it doesn’t show the Spring Boot wizard, or Run As Spring Boot App.

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?

Re: Re: Re: Error “Unrecognized VM option ‘TieredStopAtLevel=1′”

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…

Hope that helps.

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 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

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.

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.

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.

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.

Running the Application

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

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).

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.

Creation of a Spring Application

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.

Running a Spring Boot Project

If you are developing a Spring Boot project, such as one created with Vaadin Start, Spring Boot makes it easier to run a Java web application, because it takes care of starting and configuring the server.

To run your application, all you need to do is to run the Application class that contains the

main()

method that starts Spring Boot. Eclipse automatically detects that you have such a class with a

main()

method and lets you run it.

To start your application, you can do any of the following:

• Click Run Application (the “play” icon) in the toolbar.

• Select

  in the menu.

• Press Ctrl+F11.

• Select the

  
Application.java

  in the Project Explorer, right-click, and select “Run As → Java Application”.

The first time you start a Vaadin application, it downloads frontend dependencies and builds a JavaScript bundle. This can take several minutes, depending on your computer and internet speed.

You’ll know that your application has started when you see the following output in the console:


Tomcat started on port(s): 8080 (http) with context path '' Started Application in 80.189 seconds (JVM running for 83.42)


You can now open the web application in a browser at localhost:8080.

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.

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.
