<dependencies>
	<!--    alibaba cloud    -->
       <dependency>
           <groupId>com.alibaba.cloud</groupId>
           <artifactId>spring-cloud-alibaba-dependencies</artifactId>
           <version>2.2.5.RELEASE</version>
           <type>pom</type>
           <scope>import</scope>
       </dependency>
       <!--    nacos    -->
       <dependency>
           <groupId>com.alibaba.cloud</groupId>

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

   <dependencyManagement>
       <dependencies>
           <dependency>
               <groupId>com.alibaba.cloud</groupId>
               <artifactId>spring-cloud-alibaba-dependencies</artifactId>
               <version>2.2.0.RELEASE</version>
               <type>pom</type>
               <scope>import</scope>
           </dependency>
       </dependencies>
   </dependencyManagement>

然后是bootstrap.yml

spring:

    nacos:
      config:
        server-addr: 127.0.0.1:8848
  application:
    name: ruben-provider

启动项目可以看到日志输出

然后访问nacos控制台

输入默认用户名nacos密码nacos

也能看到我们的nacos单机节点正常运行

在主启动类中配置@EnableDiscoveryClient

package com.ruben;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.scheduling.annotation.EnableScheduling;

@EnableScheduling
@EnableDiscoveryClient
@SpringBootApplication
@MapperScan({"com.ruben.dao.xml"})
public class SimpleSpringbootApplication {

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

}

启动后可以看到服务已经注册成功
