ssm框架搭建问题

可能这个问题，不是啥大问题 ，但是提供了一个解决问题的思路： 当你认为不会出现问题的地方，多半就是问题的根源

当登陆界面 确认跳转到web-inf/view/admin/welcome.jsp时抛出500：

浏览器端：

HTTP Status 500 - Could not get RequestDispatcher for [/WEB-INF/view/admin/welcome.jsp/]: Check that the corresponding file exists within your web application archive!

type Exception report

message Could not get RequestDispatcher for [/WEB-INF/view/admin/welcome.jsp/]: Check that the corresponding file exists within your web application archive!

description The server encountered an internal error that prevented it from fulfilling this request.

exception

问题根源: spring-mvc.xml中出现配置错误：

总结：查看异常还是要在 console端看， 不要看浏览器端， 另外就是记着一点解决Exception ，最开始的出发点就是 console info ， 不要脱离这个， 认为绝对不会出错的地方 恰恰就是问题的根源
