前言导读
因为项目中需要获取facebook的散列，又用Google重签包，所以不是很好获取，这边就写了一个十六进制到 Base64 通过签名的里面的sha1 然后转换成哈希值的散列
输入我们的sha1 然后点击 Convent
点击ok 就要生成我们的想要的facebook 散列
具体实现

}打包成jar
编译成jar
转成exe
output选择我们的输出的exe路径
选择console
jre 运行时 我们选择相对路径方便 一点
最终效果
我们只需要保证我们的exe 和jre在同一个根目录既可以正常运行
最后总结
工具是方面给我们自己使用或者 运营专员使用，来提升我们的效率，最后我想说的实际 ，我们在现实中 一定要学会使用工具和创造工具，切记重复去做一件事情，大脑和灵魂需要进步和升华，今天的文章就讲到这里有兴趣的同学可以拿老师代码去优化修改， 今天的文章就讲到这里有兴趣的 关注我B站教程 了解更多鸿蒙开发的知识 可以关注坚果派公众号 。 谢谢
