@Reference 用在消费端,表明使用的是服务端的什么服务@RestController
public class RemoteUserController {
@Reference(version = "1.0.0",check = true)
private RemoteUserService remoteUserService;
@RequestMapping(value="/dubbo/say/{name}")
public String sayHello(@PathVariable("name") String name){
//调用服务提供者的服务
String result=remoteUserService.sayHello(name);
return result;
}
}
@Service 用在服务提供者中,在类或者接口中声明。
服务提供者实现相关的服务接口,当消费端调用相关的类时,最终会调用提供者的实现方法。@Component@Service(version = "1.0.0",timeout = 10000,interfaceClass = RemoteUserService.class)public class RemoteUserServiceImpl implements RemoteUserService { @Override public String sayHello(String name) { log.info("访问sayHello " + name); return "Hello " + name; }}
