### Apache Dubbo Component

`
public interface TestProvider {
String getName();
}
@ConditionalOnMissingBean(TestProvider.class)
@DubboService(interfaceClass = TestProvider.class)
public class TestServiceImpl implements TestService {
@Override
public String getName() {
return "getName:TestServiceImpl:";
}
}
@DubboService(interfaceClass = TestProvider.class)
public class TestServiceExtImpl extends TestServiceImpl{
@Override
public String getName() {
return "TestServiceExtImpl:";
}
}
