环境:
我有一个弹簧启动项目,1.4.2版本可以正常工作,但1.5.8版本没有。当我更改为1.5.8时,它会停止编译JSP并按原样打印页面。
以下是我的文件:

我收到错误:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available
在tomcat控制台上没有打印错误。 我试图读取1.5.8的更改日志,但在此找不到任何内容。我在这里失踪了什么?
