idea java类右侧显示文件位置 怎么取消 idea不显示java文件后缀名

直接进行以下设置，打开新的项目后，会重新恢复默认设置，所以要记得直接修改IDEA的默认设置哦~

• 关闭win10与IDEA冲突相关快捷键：



• 修改默认设置

IDEA设置输入忽略大小写

1、首先，点击左上角的File

2、然后，点击弹出的Settings选项

3、然后选择 Editor 中的 General

4、展开之后选择 Code Completion 这个选项

5、将Match Case这个勾线去掉

6、右下角Apply应用，最后ok

一：设置项目编码类型

• 打开设置 搜索 File Encoding

二：代码头部版权

• 打开设置 --> 搜索 File Templates -->选择 file Header

代码版权头部填写

/**
 * Description:
 * 
 * @Author: YangGC
 * @Date: ${MONTH}-${DAY} 
 */

1231312313

• 如图所示

三：不在IDEA中显示杂项文件,以及文件夹

• 在设置中搜索 File Types
  
  在下方的忽略文件以及文件夹的编辑框中添加上不想显示的文件以及文件夹后缀就 可以了！记得使用“ ; ”符号隔开哦
  笔者常用的设置

;*.mvn;*.idea;*.mvn,*.hprof;*.pyc;*.pyo;*.rbc;*.yarb;*~;.DS_Store;.git;.hg;.svn;CVS;__pycache__;_svn;vssver.scc;vssver2.scc;

• 添加 .gitignore 文件

.gitignore规则不生效的解决办法

把某些目录或文件加入忽略规则，明明在.gitignore配置了,还是被识别到更新内容中.

原因是.gitignore只能忽略那些原来没有被追踪的文件，如果某些文件已经被纳入了版本管理中，则修改.gitignore是无效的。

那么解决方法就是先把本地缓存删除（改变成未被追踪状态），然后再提交：

git rm -r --cached .
git add .
git commit -m 'update .gitignore'

四： 修改Maven默认设置

• Setting for New Projects 搜索maven ，设置成自己的Maven配置就可以了

五： 修改Maven默认设置idea 中 git 修改commit (ChangeList的使用)

• 打开git 窗口：双击shift 搜索GIt 或者快捷键 alt + 9

• 进入git 操作窗口
  
  添加changelist
  
  提交项目中

六： idea关闭 inlayhint(嵌入式)提示

setting->搜索“inlay” 全部取消勾选在代码里面就不显示了
