我是 Struts2 新手，正在开发一个带有文件上传选项的 Web 应用程序。一切都已配置，但是当我运行模块时 HTTP Status 404 错误:请求的资源不可用。 (链接:http://localhost:8080/File_Upload/index.jsp)。请在下面找到我的配置，

最佳答案
您必须在 default 包中的 struts.xml 中添加此操作
<action name="index">
<result>/index.jsp</result>
</action>
这样当你尝试打开http://localhost/myapp/index时它将返回 index.jsp
关于java - struts2中请求的资源不可用 文件上传，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33197573/
