安装IDEA

首先下载最新版本IDEA：https://www.jetbrains.com/idea/download/#section=windows

然后一路安装至本地，路径要记住，比如说 D:\IntelliJ IDEA 2021.3.1\bin

下载ja-netfilter(已经有大佬做好集成包了，直接用即可)

https://jetbra.in/s

下载下来后是一个压缩包 解压至本地随便一个路径（要记住） 例如 E:\Java_env\ja-netfilter

然后修改图二中的 idea64.exe.vmoptions  其路径在你安装的IDEA的bin文件夹下，选择编辑器打开修改，添加一行代码至末尾

-javaagent:[ja-netfilter的解压路径]\ja-netfilter.jar=jetbrains

图中灰色的要修改成你们刚刚下载的ja-netfilter压缩包解压出来的路径，并且指向ja-netfilter.jar，后面一定要加上=jetbrains，保存即可

打开IDEA，填写对应激活码

选择激活码激活，填写对应的激活码，该激活码在 https://jetbra.in/s 获取，也就是刚刚下载ja-netfilter的网页

填写激活即可，请按照步骤一部一部操作，失败会造成打不开IDEA，激活不了 等相关情况 进不去网页的 我这里提供了激活码，不保证是最新的
