IDEA学习笔记
.IDEA退回欢迎界面
File -> Close Project
.设置每次打开IDEA都进入欢迎界面
File -> Settings -> System Settings -> Reopen last project on startup
.Import项目和Open项目的区别
Import：指导入其他编辑器编辑的项目到IDEA，对于maven项目，一般保留src文件夹和pom.xml文件就行了
Open：直接打开IDEA项目，该项目文件夹下会有一个.idea文件夹
.Project 面板排除特定文件和文件夹
File -> Settings -> Editor -> File Types下，在"Ignore files and folders"添加 target;*.idea;*.iml;
.去掉编辑框右侧的竖线
File -> Settings -> Editor -> General -> Appearance -> "show hard wrap guide"，取消勾选
.取消拼写检查
File -> Setting -> Editor -> Inspections -> Spelling，取消勾选
.自动提示不限制大小写
File -> Settings -> Editor -> General -> Code Completion -> MatchCase，取消勾选
.取消代码折叠(取消import折叠和方法中只有一行代码导致方法被折叠)
File -> Setting -> Editor -> General -> Code Folding，取消勾选"imports"和"One-line methods"
.类或字段等信息添加鼠标悬浮提示
File -> Settings -> Editor -> General -> "Show quick documention on mouse move"
.取消方法调用时的形参名提示
File -> Settings -> Editor -> Appearance -> "Show parameter name hints" ，取消勾选
.取消 " XXX is nerver used "提示
虽然这个功能能帮我们检测出无用的代码，能提升代码质量，但是在控制器层经常看到这样的监测提示，所以个人不是很喜欢
Editor -> Inspections -> Java -> "Declaration redundancy" -> "Unused declaration"，取消勾选
.格式化整个项目
在项目目录中，右键"src"文件夹，选择"Reformat code"
.对类的头部 import 包名排序
.配置谷歌编码规范
