import org.springframework.stereotype.Component;

/* @author liuteng */
@Component
@DubboService(timeout = 500, version = “1.0.0”, interfaceClass = UserService.class)
public class UserServiceImpl implements UserService {
```
@Override
public String getUserIdByPhone(String phone) { 
    return "1000000101001";
}

}

DubboClientApplication

package com.example.demo;

import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@EnableDubbo
@SpringBootApplication
public class DubboClientApplication {
```
public static void main(String[] args) { 
    SpringApplication.run(DubboClientApplication.class, args);
}
```
}
UserController

package com.example.demo.controller;

import com.example.dubbo.facade.service.UserService;
import org.apache.dubbo.config.annotation.DubboReference;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/* @author liuteng */
@RestController
@RequestMapping(value = “user/“)
public class UserController {
```
@DubboReference(version = "1.0.0")
private UserService userService;
@GetMapping(value = "/getUserIdByPhone")
public String getUserIdByPhone(String phone){ 
    return userService.getUserIdByPhone(phone);
}
```
}

四、Facade工程

UserService

package com.example.dubbo.facade.service;

/* @author liuteng */
public interface UserService {
```
String getUserIdByPhone(String phone);
```
}
