index.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"  pageEncoding="ISO-8859-1"%>

项目结构：

Answer 1

将您的 index.jsp 直接放在 WebContent 文件夹下。

然后更改您在 web.xml 中的 welcome-file 位置

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

实际上你完全可以跳过 web.xml 中的这个配置。默认情况下，您的应用程序将查找 index.jsp。

现在 URL http://localhost:8080/EasyCCE/ 将 return index.jsp。不需要单独的控制器配置。

确保 EasyCCE 是您的 ApplicationName/ContextPath 并且您不会收到任何部署错误。

Answer 2

得到解决方案，

  <welcome-file-list>
    <welcome-file>/WEB-INF/resources/jsp/index.jsp</welcome-file>
  </welcome-file-list>
