微服务demo（二）nacos服务注册

环境：nacos1.3.0

一、服务注册

1、pom：

移步spring官网https://spring.io，查看集成Nacos所需依赖

找到对应版本点击进入查看集成说明

然后再里面找到集成配置样例，这里只截一张，其他集成内容继续向下找

            </plugin>
        </plugins>
    </build>
</project>

2、配置文件

（1）有认为，nacos配置中心配置内容必须写在bootstrap.yml文件中，如果写入application-*.yml或者application.yml中均不生效。

（2）使用application.properties也可以完成配置。我的：

spring.cloud.nacos.discovery.server-addr=172.31.7.9:8848
server.port=8877
server.servlet.context-path=/myProvider
spring.application.name=my-service

3、启动类

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

@SpringBootApplication
@EnableDiscoveryClient
public class NacosServierStart {
    public static void main(String args[]){
        SpringApplication.run(NacosServierStart.class,args);
    }
}

4、业务代码

5、测试

启动

5.1、服务注册

查看nacos也成功的注册了：

5.2、集中配置
