nacos的初始化配置

1、下载nacos服务，将cluster.conf文件中的ip设置成当前电脑的ip，端口号设置8848，启动服务

2、在每个启动类上加注解

@EnableDiscoveryClient

3、在application.yml文件中加入配置

spring:
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848   //本地+之前设置的端口号
  application:
    name: engoal-approval   //服务的名称

4、在common公共服务中引入依赖

 <dependencies>       
        <!--        服务注册/发现-->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
　　　　　//因为新版本服务注册不带这个jar，所以要单独引用
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-loadbalancer</artifactId>
            <version>2.2.1.RELEASE</version>
        </dependency>

        <!--        配置中心来做配置管理-->

            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
