How to Install Spring Boot in Eclipse | Spring Tool Suite| Updated 2022

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.

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.

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.

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.

Configuring the internal JDK

The Spring Tools contain an isolated component that runs in a separate process and provides most of the services that the Spring Tools add to their environment. This separate process is a so-called “language server”, it uses the Language Server Protocol to communicate with the surrounding editors and IDEs.

This language server itself is written in Java and requires a JRE to run. In most cases, the JRE to run this separate process will be the same JRE that is used to either run the IDE (for the Eclipse case) or the JRE that is used to run the Java language server from the Java Language Tooling Extension (in the VSCode case).

In case the tooling can’t identify those JREs, it looks in these places and uses the first

java

executable found to run this process:

  • the location configured via

    ${language-server-name}.ls.java.home

    settings. Where

    ${language-server-name}

    is one of

    spring-boot

    ,

    concourse

    ,

    cloudfoundry-manifest

    or

    bosh

    . This setting is specific fora particular language server and only affects how that server launches.
  • the location in

    JAVA_HOME

    environment variable
  • a

    java

    executable in the

    PATH

It is possible to use the Spring Boot and Java tooling with projects that require older JRE to compile and run since the JRE used for this purpose is independent of the JRE used to launch the language server itself. The best way to configure the JRE for the language server independently is to set

${language-server-name}.ls.java.home

in vscode’s user or workspace settings – in case the tooling can’t identify the correct JRE automatically.

Working a Getting Started guide with STS

This guide walks you through using Spring Tool Suite (STS) to build one of the Getting Started guides.

download spring tool suite for windows | STS
download spring tool suite for windows | STS

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.

Steps for Installing Spring Tool Suite

Step 1: Download the Spring Tool Suite tarball for Linux, from the Spring tools webpage.

Step 2: Open a terminal window and move to the location where the tarball is saved.

cd location

Step 3: Extract the tarball using the below command,

tar -xzf tar_ball_name

where,

  • x -> extract the tar
  • z -> verbose output of the extracting process
  • f -> tar archive name

Step 4: Moving STS extracted folder to the /opt directory, `/opt` is the folder intended for third party software that is not part of the core system, so that we have chosen /opt to be the folder for the software. For this use the below command,

sudo mv sts.4.20.1.RELEASE/ /opt/sts/

sts is the destination folder that will be used for storing all the files, sudo is used as /opt is owned by the root user.

Step 5: Creating soft link to launch using terminal, use the following command,

sudo ln -sf /opt/sts/SpringToolSuite4 /usr/bin

where,

  • s -> makes symbolic links.
  • f -> removes existing entries.

Step 6: Launching STS from the terminal by using following command,

SpringToolSuite4

Step 7: Launching from terminal is somewhat tedious, if you are not using terminal frequently, then we can also create a .desktop file so that it will appear in the launchpad like every other application.

Create a file using the below command in nano editor and add the below content.

sudo nano /usr/share/applications/SpringToolSuite4.desktop

[Desktop Entry]Type=ApplicationName=Spring Tool Suite 4Comment=A customized Eclipse IDE gives a better experience for Spring based Entreprise ApplicationsExec=/usr/bin/SpringToolSuite4StartupNotify=trueTerminal=falseIcon=/opt/sts/icon.xpmCategories=Development;IDE;Java

Adding the command in nano editor below,

Adding the content in below nano editor,

Now, we have setup the desktop file for Spring Tool Suite and it should be visible in the launchpad as a normal application that you would install through Ubuntu Store.

Step 8: Launching Spring Tool Suite through the applications menu or launchpad, press the super key and type Spring, now you should see the STS icon, click on that to open the application.

Below we can see the Spring Tool Suite Welcome screen,

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.

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 extension page in Visual Studio Code allows you to switch your installation to those snapshot pre-release builds instead of the latest release (e.g. in case you would like to try latest fixes and improvements before they get published as part of a release).

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.

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.
