1.项目接口

2. 编辑pom.xml和application.yml文件

2.1父工程

2.3 consumer 模块

代码结构：

dubbo注解：

Controller中使用 @DubboReference  进行依赖注入

@RestController
@RequestMapping("/test")
public class UserController {

    @DubboReference(version = "1.0")
    private UserService userService;

    @GetMapping("/get")
    public Object get(String id){

       List<SysUser> userList= userService.getUserList();

//        return "hello world !!!";
        return userList;
    }
}

2.4 provider模块

代码结构：

dubbo 注解：

UserSeviceImpl 使用 @DubboService 注解 暴露服务

@DubboService(version = "1.0")
public class UserSeviceImpl implements UserService {


    @Override
    public List<SysUser> getUserList() {
        List<SysUser> userlist = new ArrayList<SysUser>();
        SysUser user1 = new SysUser("张三",20, LocalDateTime.now());
        SysUser user2 = new SysUser("李四",30,LocalDateTime.now());
        SysUser user3 = new SysUser("王五",31,LocalDateTime.now());
        userlist.add(user1);
        userlist.add(user2);
        userlist.add(user3);
        userlist.add(user3);
        return userlist;
    }
}

Application 类加 @EnableDubbo

@EnableDubbo
@SpringBootApplication
public class CrmbeProviderApplication {

    public static void main(String[] args) {
        SpringApplication.run(CrmbeProviderApplication.class, args);

        System.out.println("--------------Dubbo Provider 启动成功-----------------");
    }

}
