Git commit后，本地代码丢失解决方法

问题描述：

提交代码时，rebase了两次，本地代码丢失了，吓得我差点跳起来。解决方法如下：
1、执行命令：

git reflog

d6ea731 (HEAD -> dev, origin/dev, master) HEAD@{0}: checkout: moving from master to dev
d6ea731 (HEAD -> dev, origin/dev, master) HEAD@{1}: merge dev: Fast-forward
37f7992 HEAD@{2}: checkout: moving from dev to master
d6ea731 (HEAD -> dev, origin/dev, master) HEAD@{3}: commit: branch test
37f7992 HEAD@{4}: checkout: moving from dev to dev
37f7992 HEAD@{5}: reset: moving to HEAD@{1}
66e655d HEAD@{6}: checkout: moving from master to dev
37f7992 HEAD@{7}: commit: commit
66e655d HEAD@{8}: checkout: moving from dev to master
66e655d HEAD@{9}: checkout: moving from master to dev
66e655d HEAD@{10}: checkout: moving from master to master
66e655d HEAD@{11}: checkout: moving from master to master
66e655d HEAD@{12}: checkout: moving from dev to master
66e655d HEAD@{13}: checkout: moving from dev to dev
66e655d HEAD@{14}: checkout: moving from master to dev
66e655d HEAD@{15}: commit: first commit
c9ae14a HEAD@{16}: commit (initial): first commit

2、用reset (Suppose the old commit was HEAD@{5} in the ref log)

git reset --hard HEAD@{7}
亲测有效！解决了～解决了～

以上。
