项目就是一个git仓库，打开隐藏的项目就可以看到：
一，Push rejected: Push to origin/liuzhihui was rejected
解决：
1.git bash中
git push -u origin liuzhihui 提示版本落后
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: ‘git pull …’) before pushing again.
hint: See the ‘Note about fast-forwards’ in ‘git push --help’ for details.
2.idea中更新
Can’t Update
No tracked branch configured for branch liuzhihui or the branch doesn’t exist.
To make your branch track a remote branch call, for example,
git branch --set-upstream-to=origin/liuzhihui liuzhihui (show balloon)
3.git bash 关联远程分支
git branch --set-upstream-to=origin/liuzhihui liuzhihui
4.idea 中push
合并 再push 成功
二，如果上一次的merge请求没有合并，又有一个push请求上来了
自动添加到上一次的merger请求中
1.点击 redis连接测试
2.点击commit，可以看到新push上来的请求自动添加到merge请求中
