nacos的使用作为注册中心

1.导入依赖

<!--nacos-->
<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-alibaba-dependencies</artifactId>
            <version>2.1.0.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>
2.在yml配置文件进行配置(每一个服务都必须有一个名字才可以)

cloud:
  nacos:
    discovery:
      server-addr: 127.0.0.1:8848
application:
  name: gulimall-coupon

3.使用@EnableDiscoveryClient注解开启服务发现功能
