ls————cmd /c dir/b
rm————cmd /c del
mv————cmd /c move
pwd————cmd /c chdir
注cmd /c是执行完命令后关闭命令行窗口、cmd /k是执行完命令后不关闭命令行窗口、cmd /c start是会打开新窗口关闭旧窗口、cmd /c start是会打开新窗口不关闭旧窗口也可以将上述命令做成bat文件放到Windows/System32目录下例如如下文件命名为ls.bat放到对应目录下cmd执行ls命令
echo off
dir接下来全局安装JAVASCRIPT_OBFUSCATOR需要提前准备好Node环境
#安装
npm install javascript-obfuscator -g
#检查是否安装成功
javascript-obfuscator -v然后在系统环境变量指定path我这里是npm安装因此找到npm路径在系统用户变量的path里例如C:\Users\zy_ys\AppData\Roaming\npm 加到系统变量的path里 还需要准备YUI压缩使用的jar包这里使用2.4.8版本下载地址提取码qc1j接下来对应本地项目改造如下代码具体改造内容为项目路径、jar包路径、压缩文件路径等完整代码如下

}如果遇到问题可以debug看下是否配置了正确的执行路径、项目路径等如果要压缩混淆的文件很少也可以配置好上述内容后执行如下命令
javascript-obfuscator D:\project\src\main\resources\static\js\login\login.js --output D:\project\src\main\resources\static\js\login\login-1689667293081-min.js这里login.js是我们要压缩混淆的文件login-1689667293081-min.js是压缩混淆后的代码挂上具体时间戳然后将其名称覆盖到对应的html页面即可
