spring-mvc ajax GET请求中未显示重定向页面

Question

我在单击按钮时将网页重定向到另一个网页。但是重定向的页面没有打开，我收到No mapping found for HTTP request with URI ['UserTest/redirect/npage'] 的错误。但是，此路径是有效的，并且是在我的项目中定义的。 npage.jsp 文件/页面也存在于视图文件夹中。那么可能是什么问题以及为什么无法访问此页面？ 我已经探索了许多类似的问题，但没有一个对我有用。因此请帮忙。

尝试在 ajax 调用中传递完整路径

url : "/UserTest/redirect" // here
