一、下载并安装， IntelliJ IDEA的官网：https://www.jetbrains.com
二、破解。
百度下载一个 JetbrainsCrack-2.6.2.jar 破解补丁。放在你的安装idea下面的bin的目录下面。 下载链接：http://idea.lanyus.com/
在安装的idea下面的bin目录下面有2个文件 ： 一个是idea64.exe.vmoptions，还有一个是idea.exe.vmoptions
用记事本打开（蓝色框） 分别在最下面一行增加一行
-javaagent:F:\idea\IntelliJ IDEA 2017.1\bin\JetbrainsCrack-2.6.2.jar
“F:\idea\IntelliJ IDEA 2017.1\bin\JetbrainsCrack-2.6.2.jar”是对应的JetbrainsCrack-2.6.2.jar的位置。
重启一下软件，在进入出现有active code选择界面的时候 写入下面注册代码：（到2099年到期）
