简单的IDEA入门记录, 以 2018.2 为准

获取最新破解补丁和注册码

破解补丁下载

在IDEA安装位置/bin下放入破解补丁, 修改idea.vmoptions文件, 增加

-javaagent:JetbrainsCrack-2.10-release-enc.jar

• Mac 应该要先打开一次程序, 因为会有验证文件完整性的过程
• 注意和下载的文件对应
• Windows 需要同时设置两个.vmoptions文件
• Windows 可能需要将-javaagent设为绝对路径
• 打开欢迎界面 Configure -> Manage Licenses -> Activation Code 输入注册码

不打开任何项目的界面 :

Configure -> Project Defaults -> Project Structure

设置 JDK 文档

• 官网下载 javadoc
• Configure -> Project Defaults -> Project Structure

Configure -> Preference -> Build Tools -> Maven -> Importing

• 自动更新 Import Maven projects automatically
• 自动下载源码和文档 Automatically Download: Sources and Documentation

Configure -> Preference -> Editor -> General -> Show quick documentation on mouse move

感觉体验不是很好, 还是自己 ctrl+J 吧

Configure -> Preference -> Editor -> General -> Auto Import

• 自动导包 Add unambiguous imports on the fly
• 导包优化 Optimize imports on the fly, 会 import java.io.* 不推荐

Configure -> Preference -> Editor -> General -> Code Completion

View -> Toolbar

安装流程查看官网

似乎顺便安装了 Hotcode 2

• cmd+alt+L 格式化代码
• ctrl+J 查看文档
• cmd+delete 删除当前行
• cmd+B/cmd+鼠标 前往定义
• alt+enter
  • 在包重复时提供选择
• cmd+N 生成 getter / setter
• cmd+F9 Build 项目
• cmd+Z / cmd+shift+Z undo / redo
• cmd+F / cmd+R Find / Replace
