RESTEasy Tutorial Part 3 - Exception Handling

RESTEasy provides support for Spring integration which enables us to expose Spring beans as RESTful WebServices.

Step#1: Configure RESTEasy+Spring dependencies using Maven.



Step#2: Configure RESTEasy+Spring in web.xml



Step#3: Create a Spring Service class UserService and update UserResource to use UserService bean.


Step#4: Same JUnit TestCase to test the REST Webservice described in Part-1.

Important Things to Keep in mind:

1. org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap Listener should be registered before any other listener.

2. You should configure resteasy.servlet.mapping.prefix <context-param> if the HttpServletDispatcher servlet url-pattern is anything other than /*

3. While using Spring integration set resteasy.scan to false or don't configure resteasy.scan parameter at all.
    Otherwise you may get REST Resource instances(UserResource) from RestEasy instead of Spring container. While running JUnit Tests I observed this random behavior.

4. You should register REST Resource as Spring bean by annotating with @Component or @Service.
