使用 Struts2 的 RequestDispatcher
目前，我无法从 Struts2 获取请求调度程序，如下所示：
RequestDispatcher rd = httpReq.getRequestDispatcher("/category.htm");
错误如下所示：
The requested resource (/xxxx/category.htm) is not available.
但在执行 http:/xxxx/yyyy/category.htm?id=21 时运行良好 有人知道吗？
Currently I fail to getRequestDispatcher from Struts2 as below:
RequestDispatcher rd = httpReq.getRequestDispatcher("/category.htm");
Error was show as below:
The requested resource (/xxxx/category.htm) is not available.
but it working well when http:/xxxx/yyyy/category.htm?id=21 execute
does anyone have idea?

如果它适用于
/category.htmURL，点击?id=21，但会转到/xxx/yyy/category.htm，那么您就不会发出与getRequestDispatcher()调用中的最终 URL 相同的请求。试试这个：If it works with the
/category.htmURL hitting?id=21, but that goes to/xxx/yyy/category.htm, then you're not making the same request as the final URL in yourgetRequestDispatcher()invocation. Try this instead:无论如何，问题可以通过下面的帖子解决，感谢约翰的回复:)

我所做的只是将这些添加到过滤器映射元素中对于 web.xml 中的 struts 过滤器：
