dubbo生成的代理类

public interface DemoService {

String sayHello(String name);

}

代理类生成入口 org.apache.dubbo.common.bytecode.Wrapper#getWrapper

实现类

@Service 
public class DemoServiceImpl implements DemoService { 
private static final Logger logger = LoggerFactory.getLogger(DemoServiceImpl.class);

@Override
public String sayHello(String name) {
    logger.info("Hello " + name + ", request from consumer: " + RpcContext.getContext().getRemoteAddress());
    return "Hello " + name + ", response from provider: " + RpcContext.getContext().getLocalAddress();
}

}
