1.下载
下载IntelliJ IDEA2019.2
百度云：https://pan.baidu.com/s/1TC9BNnm_bEJFxTjMzF1qOw
提取码：o4ez
去官网的话有墙。
IntelliJ IDEA有两个版本：社区版(Community)和旗舰版(Ultimate)。我这提供的是旗舰版(Ultimate)。
2.安装步骤
安装的话,一直点击下一步即可（放心的点，没问题的）
注意两个地方:
第一个就是:安装位置,将默认的c盘下,改为自己想要安装的地方
第二个就是有一个选择的地方，勾选64bit即可，其他的不用管。
这个可以去原文看。
安装完了之后先不要急着打开IDEA
3.破解过程
1、修改hosts文件
1.1打开hosts文件
windows的hosts文件路径路径：C:WindowsSystem32driversetc
1.2使用文本编辑器编辑hosts文件
1.3、在hosts文件末尾追加记录
0.0.0.0 account.jetbrains.com
0.0.0.0 www.jetbrains.com
2.在lanyus大神那里获取注册码，点击【获取注册码】按钮。复制注册码
3.打开IDEA，选界面，是否导入之前的设置（不导入，Don’t…）等，然后在这个地方停下来。选择第二个
选Activation code，然后粘贴你的注册码。
到此就成功破解了。
下面粘下我的注册码（亲测有效）：
