我的java spring mvc项目位于4.0.6.RELEASE spring version Project在http://localhost:8080/加载主页。当我在pom.xml中更改为更新的4.3.9.RELEASE时，我收到错误404 tomcat page。
我使用tomcat Apache Tomcat / 9.0.0.M22，IntelliJ，windows10，chrome（但边缘也显示404）。我试图重建项目，刷新maven，但它没有用。
我已经附加了配置文件和文件夹结构。我希望它不是太多的代码。感谢您的帮助。

您已在类级别上映射/，因此您无需在方法级别上再次映射它。您这样做意味着尝试访问//上的资源，这不仅是可能的。这是因为方法上的map与类上的map相关。
所以只需用
替换控制器类的mainPage方法上的@RequestMapping(value = "/")
@RequestMapping
或者
@RequestMapping(value = "")
或者
@RequestMapping(method = RequestMethod.GET)
答案 1 :(得分：0)
我找到了解决方案。我的.jsp文件中有2个没有taglibs。我添加了这个：
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
Spring 4.0.6.RELEASE在某种程度上没有它们。
