JAX-RS works with Enterprise JavaBeans technology (enterprise beans) and Contexts and Dependency Injection for the Java EE Platform (CDI).
In general, for JAX-RS to work with enterprise beans, you need to annotate the class of a bean with @Path to convert it to a root resource class. You can use the @Path annotation with stateless session beans and singleton POJO beans.
The following code snippet shows a stateless session bean and a singleton bean that have been converted to JAX-RS root resource classes.
@Stateless @Path("stateless-bean") public class StatelessResource {...}
@Singleton @Path("singleton-bean") public class SingletonResource {...}
Session beans can also be used for subresources.
JAX-RS and CDI have slightly different component models. By default, JAX-RS root resource classes are managed in the request scope, and no annotations are required for specifying the scope. CDI managed beans annotated with @RequestScoped or @ApplicationScoped can be converted to JAX-RS resource classes.
The following code snippet shows a JAX-RS resource class.
@Path("/employee/{id}") public class Employee { public Employee(@PathParam("id") String id) {...} }
@Path("{lastname}") public final class EmpDetails {...}
The following code snippet shows this JAX-RS resource class converted to a CDI bean. The beans must be proxyable, so the Employee class requires a non-private constructor with no parameters, and the EmpDetails class must not be final.
@Path("/employee/{id}") @RequestScoped public class Employee { public Employee() {...}
@Inject
public Employee(@PathParam("id") String id) {...}}
@Path("{lastname}") @RequestScoped public class EmpDetails {...}
