JavaEE with Spring Security @RolesAllowed

   @RolesAllowed({"ROLE_ADMIN"})  
   @GET  
   public User getObject(final @Context SecurityContext securityContext) {  
     User user = getUserFromSecurityContext(securityContext);  
     if(user == null) {  
       throw new UserNotFoundException();  
     }  
     return new User(user);  
   }  

JavaEE REST JAX-RS with Spring Security

Java EE REST JAX-RS with Spring Security


If you are using a JavaEE application server like Jboss, WildFly, GlassFish you get JAX-RS , JPA etc runtimes for 'free', if using Tomcat, Jetty etc, you might as well use the full Spring stack.
I tested on Jboss EAP 6.11, 7, WildFly and Glassfish.
