撤銷並保留修改

參數 –soft

1. # 先進行commit ，之後後悔啦
2. $ git commit -am "對首篇報告研究員字段改為author_name"

執行git log

1. $ git log

25. commit 5a1d18a032d8c9269613ff14593847f82043e627

可以看出，第一個是我剛剛commit的，我要撤銷，當然是選擇第二個；

執行命令git reset --soft <commit>

$ git reset --soft 5029f0cc08cf

• 之後我們查看下，狀態：

1. $ git status
2. On branch yutao
3. Your branch is up-to-date with ‘origin/yutao‘.
4. Changes to be committed:
5. (use "git reset HEAD <file>..." to unstage)
7. modified: dataservice/app/ggservice/v1/event/service/InfoEventService.java

可以看出已經回撤啦，並且保留了修改。

參數 –mixed

1. $ git reset --mixed 5029f0cc08cff
2. Unstaged changes after reset:
3. M dataservice/app/ggservice/v1/event/service/InfoEventService.java
5. yutao@yutao MINGW64 /d/sts/workspace/ggservice (yutao)
6. $ git status
7. On branch yutao
8. Your branch is up-to-date with ‘origin/yutao‘.
9. Changes not staged for commit:
10. (use "git add <file>..." to update what will be committed)
11. (use "git checkout -- <file>..." to discard changes in working directory)
13. modified: dataservice/app/ggservice/v1/event/service/InfoEventService.java
15. no changes added to commit (use "git add" and/or "git commit -a")

這種方式也是可以的。
參數--soft和--mixed區別：

git reset –hard <commit_id>

這種方式，我個人是不推薦，它也是撤銷，但是不會保留修改。
除非你確實是不想要剛剛commit的內容，否則，這個操作會讓你之前幹的活，白幹。
所以非常不推薦這個方式。

git撤銷commit 並保存之前的修改
