Exporting services

There is only one way of registering a service in the registry server. You can use @Publish annotation for this purpose:

@Service
@Publish
public class MyServiceImpl implements MyService {

A default behavior of @Publish annotation is that the first interface implemented by a bean (here: MyService) is considered a service contract and with use of this contract, the service is registered in the service registry.

If you want to control a contract used for registering the service, you can parametrize the anntation:

@Service
@Publish(MyService.class)
public class MyServiceImpl implements FirstService, SecondService, MyService {

By doing so, you explicitly point an interface that will be considered a service contract and used for registry and discovery.
