Annotation Interface Service

@Qualifier
@Documented
@Retention(RUNTIME)
@Target({PARAMETER,FIELD})
public @interface Service

This annotation enables the use of registered services from the service registry in an injection context.

Instead of doing something like:

 
   @Inject
   public TestClass(ServiceRegistry registry) {
     var playerManager = registry.defaultInstance(PlayerManager.class);
     playerManager.onlineCount();
   }
 
 

Using this annotation you can do something like:

 
   @Inject
   public TestClass(@Service PlayerManager playerManager) {
     playerManager.onlineCount();
   }
 
 

Note: If a service or a service name is requested that the service registry does not know null is passed as parameter value.

Since:
