jar包加密程序，防止反编译
本窗体程序基于开源项目xjar

其中xjar和loadkit我这里maven下载不下来可以自己找源码地址下载后编译打包到本地maven仓库

3.测试启动
4.使用
指定加密前jar包路径(例如：D:\work\zike\target\zike.jar)
指定加密密码
加密后JAR包输出路径(例如：D:\work\zike\target\zikeMm.jar)
(1)命令行启动,输入密码
java -jar zikeMm.jar
(2)传参启动
java -jar zikeMm.jar --xjar.password=123
(3)后台启动
nohup java -jar zikeMm.jar --xjar.keyfile=password.key
备注：
（1）输入启动密码错误无法启动
（2）加密后反编译失败
（3）可以直接打包为EXE程序
打包命令：
mvn jfx:native
打包后
APP包为jar包需要自己配置运行环境
native包为EXE程序自带运行jre环境
