Spring MVC @Autowired 和 @ModelAttribute HTTP 状态 404 - /WEB-INF/circle。jsp

Question

*朋友们，大家好！无论我尝试什么，我仍然收到 404 错误消息，我真的不知道该怎么做。我在这 2 天内尝试修复它，但仍然无望：当我点击 index.jsp 上的 link，而不是获取 view.jsp 页面时，我得到： HTTP 状态 404 - /WEB-INF/circle.jsp

感谢大家的支持。我无意中发现了错误：

在MainController.java我用IDEA导入建议org.springframework.web.portlet.ModelAndView； insted 导入 org.springframework.web.servlet.ModelAndView；现在它工作正常。谢谢。
