本篇为idea的破解教程，非常可用，适合小白学习。
Intellij IDEA安装教程地址：https://blog.csdn.net/qq_41879385/article/details/81952656
安装好了idea后，就可以破解了，如图，
1.这个是破解界面，选择Active code。
2.把下载好的JetbrainsCrack-3.1-release-enc.jar 文件放在之前安装好的idea的bin目录下。
在两个文件的用Notepad++或者用记事本打开这两个文件，都写上-javaagent:D:\Intellij IDEA2018.2.2\bin\JetbrainsCrack-3.1-release-enc.jar，也就是刚才你放JetbrainsCrack-3.1-release-enc.jar的地址。
在C盘的，C:\Windows\System32\drivers\etc\hosts，在hosts里面加上这句0.0.0.0 account.jetbrains.com，接下来开始破解，在Active code输入一下这段，
