今天遇到了一个500的错，根据提示反复核对代码都没有错误，后来发现在<jsp>标签的开始和结束中间加了空格，所以才会出现这样的提示错误
![The server encountered an unexpected condition that prevented it from fulfilling the request. /main.jsp (line: [18], column: [40]) Expecting](https://img.liuyixiang.com/image/2019/5/N3q26v.png "The server encountered an unexpected condition that prevented it from fulfilling the request. /main.jsp (line: [18], column: [40]) Expecting")
把空格删除，即可运行
