java.lang.StackOverflowError错误

做java以来第一次遇到内存溢出的情况，刚开始是一脸懵逼的！

个人发现java会出现内存溢出的情况，其原因是：死循环、过深的递归（包括自己调用自己的部分情况，自己调用自己有时会陷入递归出不来）

解决办法：找到报错的那一行，消除死循环或者过深的递归即可！

报错信息：

严重: 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
