思路：
先用git status 查找出哪些文件被修改过了，然后 只git commit odin/code/pom.xml
1、
$ git status （查看当前更改的代码）
On branch master
Your branch is up to date with 'origin/master'.
Changes to be committed:
(use "git reset HEAD <file>..." to unstage)
modified: odin/code/pom.xml
faith@faith_java-PC MINGW64 /d/aa/testcommit/vvv/odin (master)
2.
$ git pull （拉取最新代码）
Already up to date.
faith@faith_java-PC MINGW64 /d/aa/testcommit/vvv/odin (master)
3.
$ git commit odin/code/pom.xml -m "test commit" （提交部分代码加备注）
[master f0e1185] test commit
1 file changed, 1 insertion(+), 1 deletion(-)
faith@faith_java-PC MINGW64 /d/aa/testcommit/vvv/odin (master)
4.
$ git push origin master （推送到远程服务器）
