idea总结
一、关闭注释折叠
1.1、现象
1.2、解决方法
File ==> Settings ==> General ==> Apperance ==> 取消勾选Render documention comments;
1.3、效果
1.4、参考
https://blog.csdn.net/ibigboy/article/details/129258800二、忽略提交部分文件
.idea
.mvn
.mvnw
mvnw
mvnw.cmd
*.iml
HELP.md三、新建Java文件时，自动生成作者信息
File ==> Settings ==> Editor ==>File and Code Templates ==> Includes ==> File Header
/*** @Author : 一叶浮萍归大海* @Date: ${DATE} ${TIME}* @Description: */ 
四、新版Idea(2022)的Git不显示local代码
4.1、现象
4.2、解决方法
File==》Settings==》Version Control==》Commit==》取消勾选第一项
