Java web application that provide REST web services. An example app for trying out some of the JDK 8 and Spring 4 features.

29/10/2014 : The Java 8 functional interfaces API do remind me of Google Guava library and Groovy closures....... =) The streams API seem interesting

And finally some thread-safe date time API within JDK!

• Gradle : build
• Jersey : REST web service
• Spring 4 : Dependencies injection
• Jackson 2 : JSON processing
• Jetty : Servlet container

Testing frameworks : jersey-test,rest-assured, spring-test, junit, spock

Jersey client is generated from the WADL using wadl2java tool

• Java 1.8
• Gradle

Execute the following command:

./gradlew clean build

This will compile, run the tests and package. The artifact should be available in the directory: build/

Execute the following command :

./gradlew idea

Compile and run the web application with Jetty plugin:

./gradlew clean jettyRunWar

With the web app running on Jetty, you can then access the application endpoint from base URL :

http://localhost:8080/jerseyexample/api/*

You can use any REST client to access the REST api. If you're using Chrome browser, you can use extensions such as "Advanced Rest Client" to do so.

Example, api URL to access order :

http://localhost:8080/jerseyexample/api/order

The versioning of the API is by the Accept/Content-Type headers. So for example if you would like to access version 2 of the api, set the following headers on the client:

Accept : "application/vnd.org.wai.jerseyexample-v2+json"

With the web app running on Jetty, you can access the Jersey generated WADL from the URL below:

http://localhost:8080/jerseyexample/api/application.wadl

http://localhost:8080/jerseyexample/api/application.wadl?detail
