简单便捷！
由于JetBrains封杀，大部分激活服务器已经不能使用，如果以上方法无效，则可以使用下面的比较麻烦的方法，但是有效期是到December 31，2099（emmmm，也算是永久破解了吧，毕竟是到2099年）
（1）下载破解补丁
把下载的破解补丁放在你的idea的安装目录下的bin的目录下面（如下图所示），本文示例为G:ideaIntelliJ IDEA 2017.3.4
破解补丁下载：http://idea.lanyus.com/jar/JetbrainsCrack-2.7-release-str.jar
（2）修改配置文件
打开并编辑 idea.exe.vmoptions和idea64.exe.vmoptions这两个文件（使用记事本、ultraedit或notepad++等编辑器打开），在上述两个文件的最后一行均加上下面这段代码
-javaagent:G:ideaIntelliJ IDEA 2017.3.4inJetbrainsCrack-2.7-release-str.jar（注意：不要忘记修改成你自己idea的安装目录和对应的jar的版本）
（3）输入激活码
启动idea，选择Activation Code，并输入如下激活码：
