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);
}

- 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/',
……
