Answer 1

放置welcome-file标记中提到的索引。*文件在哪里？
当应用程序启动时，它正在检查welcome-files文件夹中web.xml中提到的WebContent。但如果您将它们放在WebContent/jsps/内，则找不到所请求的文件。这可能会导致404。

解决方案：

1.您可以将jsps移动到WebContent目录 2.在welcome-file标记中，给出index.jsp的完整路径示例：<welcome-file>/jsps/index.jsp</welcome-file>
3.由于您使用Spring和InternalResourceViewResolver，您还可以配置控制器以加载欢迎页面而不是移动文件。示例：

@RequestMapping(value="Login.jsp")
    public ModelAndView showLoginPage(HttpServletRequest request, HttpServletResponse response ){
        return new ModelAndView("Login");
    }

然后使用网址访问该网页： http://localhost:port/context_root_of_your_application/Login.jsp

Dispatcher Servlet将选择此调用 - 重定向到控制器 - 在/ jsps /中查找视图（“Login”），如果找到匹配的jsp，它将重定向到该jsp。

希望这有帮助
