Tomcat在启动时找不到index.jsp

Question

我有一个带弹簧的J2ee应用程序。我已在页面上应用了一些修改但现在，当我尝试启动服务器时，我有这个：

这是application-servlet.xml

</web-app>

这是jsp文件：

我不知道为什么tomcat找不到index.jsp。

Answer 1

您的index.jsp位于“WEB-INF”目录中，url无法访问该目录。将其移至应用程序的根目录。

另一种选择是将第一个调用重定向到弹簧控制器。例如，创建一个index.html并添加一个重定向，即i.E。：

<meta http-equiv="refresh" content="0; url=/app/">

Answer 2

您必须将index.jsp文件保存在公用文件夹中，即WebContent文件夹以便直接访问。
