我正在开发一个使用 struts2 构建的网站。我们的绝大多数目标都会生成 xml，因此将结果映射到 jsp 页面是有意义的。我们的几个目标实际上生成了二进制文件。我想知道是否有一种方便的方法来表示结果应该来自 servlet/控制器而不是 jsp。
显然，这可以通过修改 web.xml 来完成，这样 struts 过滤器不适用于这些目标并将这些目标映射为 servlet，但这并不理想。目前，struts 过滤器适用于整个站点，我们希望保持这种状态。
有想法吗？
谢谢！
I'm working on on a site built using struts2. The vast majority of our targets generate xml, so mapping the result to a jsp page makes sense. A couple of our targets actually generated binaries. I'm wondering if there is a convenient way to say that the result should come from a servlet/controller instead of a jsp.
Obviously this could be done by modifying the web.xml so the struts filter doesn't apply to those targets and mapping those targets as servlets, but this is non-ideal. Currently, the struts filter applies to the entire site, and we would like to keep it that way.
Ideas?
Thanks!
