Spring HATEOAS

This project provides some APIs to ease creating REST representations that follow the HATEOAS principle when working with Spring and especially Spring MVC. The core problem it tries to address is link creation and representation assembly.

Working with Spring HATEOAS

Since all commits are headlined with its github issue, git will treat it as a comment. To get around this, apply the following configuration to your clone:

git config core.commentchar "/"

Making a release

1. Create a new release (on the main branch).

   % ci/create-release.sh <release ticket without hash> <release version> <next snapshot version>

2. With the release tagged, push the tagged version to the release branch.

   % git checkout -b release
   % git reset --hard <tag>
   % git push -f origin release

Note	You can chain the previous set of commands together using &&.

The pipeline will build and release the "release" branch. It will also build a new snapshot and stage it on artifactory. And if it’s a .RELEASE, the pipeline will push it out to Maven Central. To complete a release on Maven Central, you must login to the server shown in pom.xml, close, and release. This is a stop gap to guard against bad releases accidentally getting pushed out to Maven Central.

Running CI tasks locally

Since the pipeline uses Docker, it’s easy to:

• Debug what went wrong on your local machine.

• Test out a a tweak to your test.sh script before sending it out.

• Experiment against a new image before submitting your pull request.

All of these use cases are great reasons to essentially run what Jenkins does on your local machine.

Important

To do this you must have Docker installed on your machine.

1. docker run -it --mount type=bind,source="$(pwd)",target=/spring-hateoas-github adoptopenjdk/openjdk8:latest /bin/bash

   This will launch the Docker image and mount your source code at spring-hateoas-github.

2. cd spring-hateoas-github

   Next, run the test.sh script from inside the container:

3. PROFILE=none ci/test.sh

Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.

If you need to test the build.sh script, then do this:

1. docker run -it --mount type=bind,source="$(pwd)",target=/spring-hateoas-github --mount type=bind,source="/tmp/spring-hateoas-artifactory",target=/spring-hateoas-artifactory adoptopenjdk/openjdk8:latest /bin/bash

   This will launch the Docker image and mount your source code at spring-hateoas-github and the temporary artifactory output directory at spring-hateoas-artifactory.

   Next, run the build.sh script from inside the container:

2. ci/build.sh

Important

build.sh will attempt to push to Artifactory. If you don’t supply credentials, it will fail.

Note	Docker containers can eat up disk space fast! From time to time, run docker system prune to clean out old images.
