A hello world server you can register yourself on. It is build with dropwizard and gradle.
Just run ./gradlew jar (gradlew.bat jar for windows users). The jar will be in build/libs/xxx.jar.
You have to have a PostgreSQL server up and running with a database called HelloWorld. You can create the necessary tables by running:
java -jar xxx.jar db migrate hello-world.yml
Just import this project as a gradle project (File -> Import -> Gradle)
java -jar xxx.jar server hello-world.yml
Everything happens on /hello-world. A normal GET gives you a "Hello Stranger!". If you specify the param name in the url, it will greet you by name. If you do a POST with the data name=yourname&address=Mr it will save that and greet more gracefully on GETs. If you send a DELETE with a param name in the url, the corresponding record in the database will be deleted.
curl -i http://localhost:8080/hello-world
curl -i http://localhost:8080/hello-world?name=Foo
curl --data "name=Foo&address=Dr" http://localhost:8080/hello-world
