[Java知识库]java解压jar包再重新打包jar包以及maven分离依赖包的配置

前言
线上包，要加一个加密的配置包，但是不想重新打包过去，值加一个配置类

jar 包解压和重新打包命令

可以用解压软件解压也可以用命令解压

解压jar包命令: jar xvf xxx.jar

打包jar包命令: jar cvfM0 admin.jar ./* ( * 或者 ./* 都可以)

1. 先把 这个jar 解压了，然后把 BOOT-INF/lib 里面的jia包该添加添加该替换替换，如果只是增加class类，则到 BOOT-INF/classes 把相应的class放到相应的类路径上

2. 替换好后，可以用这个指令： jar cvfM0 business-starter.jar * ( * 表示当前目录所有文件)

3. 重新打包好后，替换过去重启服务即可
