start.spring.io initializr

This repository configures a Spring Initializr instance with a custom UI running at https://start.spring.io. The following modules are available:

  • start-client: client-side assets

  • start-site: server infrastructure and metadata configuration

  • start-site-verification: tests to verify the validity of the metadata

Using

There is a dedicated page that describes how you can interact with the service.

Building from Source

You need Java 17 and a bash-like shell.

Building

Invoke the build at the root of the project

$ ./mvnw clean install

The project also includes a number of longer-running verification tests. They can be built and run using the verification profile:

$ ./mvnw -Pverification clean install

The project’s other tests are not included in the verification profile. All of the project’s tests can be run using the full profile:

$ ./mvnw -Pfull clean install

If building start-client fails, you may have an outdated cache that can be deleted as follows:

$ cd start-client
$ rm -rf .cache node_modules

Running the app locally

As long as you’ve built the project beforehand (in particular start-client), you can easily start the app as any other Spring Boot app:

$ cd start-site
$ ../mvnw spring-boot:run

Running the app in an IDE

You should be able to import the project into your IDE with no problems. Once there you can run the StartApplication from its main method and debug it. If you also need to work on the library, adding the initializr project in your workspace would make sure to reload the app whenever you make any change.

This is the recommended way to operate while you are developing the application, especially the UI.

Reusing the Web UI

This instance has a thin layer with our opinions about getting started with Spring Boot. You can reuse them but please keep in mind that this is not supported with the same level as the Spring Initializr library. The Web UI, in particular, is for our own purpose and is not particularly engineered to be easily extended.

Deploying to Cloud Foundry

If you are on a Mac and using homebrew, install the Cloud Foundry CLI:

$ brew install cloudfoundry-cli

Alternatively, download a suitable binary for your platform from Pivotal Web Services.

You should ensure that the application name and URL (name and host values) are suitable for your environment before running cf push.

First, make sure that you have built the application, then make sure first that the jar has been created:

$ cd start-site
$ ../mvnw package

The project creates a regular library jar and a repackaged archive that can be used to start the application with the exec classifier. Once the build as completed, you can push the application:

$ cf push your-start -p target/start-site-exec.jar
