java.lang.StackOverflowError錯誤

做java以來第一次遇到記憶體溢出的情況，剛開始是一臉懵逼的！

個人發現java會出現記憶體溢出的情況，其原因是：死循環、過深的遞歸（包括自己調用自己的部分情況，自己調用自己有時會陷入遞歸出不來）

解決辦法：找到報錯的那一行，消除死循環或者過深的遞歸即可！

報錯資訊：

嚴重: Servlet.service() for servlet [springmvc] in context with path [/OABase] threw exception [Handler processing failed; nested exception is java.lang.StackOverflowError] with root cause
java.lang.StackOverflowError
