参考了F8大神的思路，但是等到真正动手，逆向分析写代码的时候才发现知道怎么做和真正做起来还是蛮大距离的
分析的思路我就不说了……太麻烦了……看代码吧……真的有兴趣的可以留言
和吾爱的朋友们讨论之后发现上传的附件有些问题，打包有错，我会更新附件并上传，朋友们也可以用我贴出来代码编译运行。同时发现因为我们在没有购买full版本的时候只能下到demo版本，这两个版本的代码是不一样的，所以即使激活了也只是一个使用期限很长的demo版本。还是在论坛下载流出的full版本吧，给各位朋友带来困扰了
先贴上代码

附上注册机
注册方法：
1、先在官网注册并下载一个40天试用版，注册的时候要写姓名和邮箱，记好
2、解压缩后运行，出现下图所示
3、去图上所示URL，把许可证数据和注册时所用信息填入，获得一个试用版Key，不用管
4、运行附件中的jar文件，得到一个Key，粘贴入许可证密钥中，点击verify即可。附件比较大，用网盘了http://pan.baidu.com/s/1bNjjyu
之所以要有步骤3，是为了把你的机器信息留在官方数据库中，这样才能更新。
