(Do not use @ for indentation) in 'reader', line 19, column 13: active: @profileActive@ ``` POM新增配置如下: ```xml dev dev true test test pro pro ``` 配置了以上设置会maven会出现可选择打包环境选项，可选择对应的启动环境 [](https://img2022.cnblogs.com/blog/2501675/202206/2501675-20220615174607771-1229088881.png) 对@profileActive@标识符的解析插件 ```xml org.apache.maven.plugins maven-resources-plugin 3.1.0 @ false ``` resource的配置 ```xml src/main/resources true **/* ``` 最后刷新mvn [](https://img2022.cnblogs.com/blog/2501675/202206/2501675-20220615174446686-804062907.png) 如果不行clean再更新一次
