idea激活，使用破解补丁无需注册码，记录。

1. 下载JetbrainsCrack.jar破解补丁无需使用注册码，下载地址：http://idea.lanyus.com/jar/JetbrainsCrack-2.7-release-str.jar 
参考：http://idea.lanyus.com/ 或者：http://pan.baidu.com/s/1pLEZKiJ 

2. 修改配置文件

进入自己安装idea路径的bin目录下，(不知道自己安装在哪儿的同学，请右击桌面的idea图标，选择属性，在目标这个地方就可以找到了)，将刚刚下载好的JetbrainsCrack.jar复制到此目录下；

还是在bin目录下，找到 idea.exe.vmoptions和 idea64.exe.vmoptions.用记事本打开它们，在两个文件最后分别加上（

注意：按照自己的目录和下载的JetbrainsCrack稍作修改，不要盲目复制

）：
-javaagent:E:\work\Idea\IntelliJ IDEA 2017.1.1\bin\JetbrainsCrack-2.7-release-str.jar
