原因很清楚，按照提示进行reset和checkout操作即可。具体原因，git的工作区-暂存区-本地仓库和远程仓库四者的关系已经很清楚，如下图

三、解决方法
1.打开git bash，这个才是底层。

2.进入需要恢复目录，运行reset命令

$ git reset .
Unstaged changes after reset:
D mybatis-06/src/main/java/com/rui/dao/TeacherMapper.java
D mybatis-06/src/main/java/com/rui/pojo/Student.java
D mybatis-06/src/main/java/com/rui/pojo/Teacher.java
D mybatis-06/src/main/java/com/rui/utils/MyBatisUtils.java
D mybatis-06/src/main/resources/com/rui/dao/StudentMapper.xml
D mybatis-06/src/main/resources/com/rui/dao/TeacherMapper.xml
3.运行checkout

$ git checkout .
即可恢复
