nacos配置出错，Server check fail, please check server 127.0.0.1 ,port 9848 is available , error ={}

错误原因是引入了

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

配置文件在同时存在application.properties和application.yml时，应该修改application.yml为bootstrap.yml。

spring:
  #配置中心
  application:
    name: module-auth
  cloud:
    nacos:
      config:
        server-addr: 127.0.0.1:18848
