 定义DTO和Provider接口：

package org.example.testDubbo.api.dto;

import lombok.Data;

import java.io.Serializable;
import java.util.Random;

@Data
public class UserDTO implements Serializable {

    private Long id;
    private String name;
    private Integer age;

    public static UserDTO mockUser(Long id){
        UserDTO userDTO = new UserDTO();
        userDTO.setId(id);
        userDTO.setAge(18);
        userDTO.setName("张三_"+userDTO.getId());
        return userDTO;
    }
}

package org.example.testDubbo.api.provider;

import org.example.testDubbo.api.dto.UserDTO;

public interface UserProvider {

    UserDTO getById(Long id);

配置文件application.yml:

dubbo:
  application:
    name: testProvider
    qos-port: 22221
  registry:
    address: zookeeper://localhost:2181
    group: registry_group_testDubbo_service
  protocol:
    id: dubbo
    name: dubbo
    port: 8088
  scan:
    base-packages: org.example.testDubbo.testProvider.provider

实现provider接口：

package org.example.testDubbo.testProvider.provider;

import org.apache.dubbo.config.annotation.DubboService;
import org.example.testDubbo.api.dto.UserDTO;
import org.example.testDubbo.api.provider.UserProvider;

@DubboService
public class UserProviderImpl implements UserProvider {

    @Override
    public UserDTO getById(Long id) {
        System.out.println("我是服务提供者，被调用了");
        return UserDTO.mockUser(id);
    }
}

            <type>pom</type>
        </dependency>
    </dependencies>

</project>

配置文件application.yml:

server:
  port: 80

dubbo:
  application:
    name: testConsumer
    qos-port: 22222
  registry:
    address: zookeeper://localhost:2181
    group: registry_group_testDubbo_service
  protocol:
    id: dubbo
    name: dubbo
    port: 8088
#  consumer:
#    check: false

测试类Controller:

package org.example.testDubbo.testConsumer.controller;

import org.apache.dubbo.config.annotation.DubboReference;
import org.example.testDubbo.api.dto.UserDTO;
import org.example.testDubbo.api.provider.UserProvider;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping(value = "/user")
public class UserController {

    @DubboReference
    private UserProvider userProvider;

    @GetMapping(value = "/getById")
    public UserDTO getById(@RequestParam Long id){
        return userProvider.getById(id);
    }

}

部署dubbo-admin
8.1 下载源码：https://github.com/apache/dubbo-admin.git
8.2 由于本测试dubbo版本是3.0.7，因此我拉取了靠近该版本的git版本：2353c814

8.3 修改子工程dubbo-admin-server的配置文件:application.properties

……
admin.registry.address=zookeeper://localhost:2181
admin.config-center=zookeeper://localhost:2181
admin.metadata-report.address=zookeeper://localhost:2181

admin.registry.group=registry_group_testDubbo_service
admin.config-center.group=registry_group_testDubbo_service
admin.metadata-report.group=registry_group_testDubbo_service
……

8.4 启动子工程dubbo-admin-server（默认会占用端口8080，用于ui工程访问，可修改该端口）
8.5 启动ui工程dubbo-admin-ui，启动命令：

npm run dev

启动成功后会打印访问地址：http://localhost:8082/
8.6 如需修改dubbo-admin-server端口，需要同时修改2处：
dubbo-admin-server的配置文件application.properties:

server.port=8989

dubbo-admin-ui的配置文件vue.config.js:


module.exports = {
	……
    proxy: {
      '/': {
        target: 'http://localhost:8989/',
    ……
