Spring官方的說法是，在同一個(gè)切面內(nèi)，同類型（前/后）的通知順序是不確定的。因?yàn)橥ㄟ^反射確定類中聲明順序（這句話的意思，我也不理解）。

見官方文檔說明（同時(shí)給出了排序的建議）：

When two pieces of advice defined in?the same?aspect both need to run at the same join point, the ordering is undefined (since there is no way to retrieve the declaration order via reflection for javac-compiled classes). Consider collapsing such advice methods into one advice method per join point in each aspect class, or refactor the pieces of advice into separate aspect classes - which can be ordered at the aspect level.

我測(cè)試了下，發(fā)現(xiàn)當(dāng)有around配置時(shí)，after和afterReturning的執(zhí)行順序與他們?cè)赬ML文件中配置的順序是相反的，原理我也沒有搞清楚。
