Intellij IDEA 由於有使用期限的原因，一個月試用期過后就是出現如下圖的界面：
有三種可以繼續使用的方式：
1.購買JetBrains賬號；
2.注冊碼（Activation code）;
3.許可證服務器（License server）；
現在，就詳細說說第二種方式，注冊碼破解IDEA，獲得使用權！
一.下載破解補丁文件
下載地址：JetbrainsCrack-3.1-release-enc.jar
下載好以后保存到 IDEA 的bin目錄下
二、修改配置信息
找到bin目錄下的idea.exe.vmoption、idea64.exe.vmoption，選擇打開方式為IDEA
-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA 2018.2.5\bin\JetbrainsCrack-3.1-release-enc.jar（目錄根據自己存放地址進行相應的修改）
三、復制粘貼注冊碼
注冊碼：

四、重啟IDEA，差不多就可以了。
注意：注冊碼有時間限制，如果提示注冊碼到期，上網搜索還在使用期限內注冊碼粘貼上就可以了，其他步驟不需要重復操作。
