依赖关键

SpringBoot版本和com.alibaba.cloud版本需要对应，不然会程序会启动失败
作者使用的版本

SpringBoot: 2.1.6.RELEASE
alibabacloud: 2.1.2.RELEASE

主要的程序

启动文件

package com.example.user;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

/**
 * @author ljj
 * @date 2023/8/25 11:15
 * @desc
 */
@SpringBootApplication
@EnableDiscoveryClient
public class UserApplication {

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

}
