maven resource 组件可以把pom的变量替换到相关的resouces目录中的资源文件变量
示例项目：内容中心 （文章管理） 生成jar包，生成docker ，生成k8s文件

4.重要总结
4.1 在pom文件中，引用maven变量使用 ${变量名}即可
4.2 在springboot项目中，使用maven resources组件时，使用@变量名@ 进行取值(因为springboot项目中进行了特殊处理）
4.3 在使用maven resources组件时
* 匹配 0或N个字符 ** 匹配 0或N个目录 如果使用*不能实现相应功能，请切换** 即可 dev/** pro/**
4.4 在使用maven resources组件时，只要增加了resource这个节点，必须重新指定resources文件夹位置
如示例：
