1.确认yml的配置

spring:
  application:
    name: test
  profiles:
    active: test
  main:
    allow-bean-definition-overriding: true
  cloud:
    nacos:
      discovery:
        enabled: true
        namespace: test
        group: test
        server-addr: 10.1.1.2:8848 #Nacos服务注册中心地址
        registerEnabled: true
      config:
        enabled: true
        server-addr: 10.1.1.2:8848
        config-retry-time: 3
        namespace: test
        prefix: ${spring.application.name}
        group: test
        file-extension: yml
        refresh-enabled: true
        extension-configs:

2.如果yml的配置没有问题，那么就是yml的配置没有生效，在pom中指定使用前yml(当前是：test)

<resources>
    <resource>
        <directory>src/main/resources</directory>
                <excludes>
                    <exclude>config/**</exclude>
                </excludes>
        </resource>
        <resource>
                <filtering>true</filtering>
                <directory>src/main/resources/config/test</directory>
        </resource>
        <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                    <include>**/*.png</include>
                </includes>
         </resource>
</resources>
