问题描述
我想像这样使用 RequestDispacher 将请求从 Servlet 转发到 Action
I want to forward a request from Servlet to Action like this using RequestDispacher like this
RequestDispatcher dispatcher=request.getRequestDispatcher("hello.action"); dispatcher.include(request, response);
它不工作.我该如何解决这个问题?
It's not working. How can I resolve this problem?
推荐答案
为了做到这一点,您可能还需要将过滤器设置为在 FORWARD 上运行(并且如您的代码所示,包括,尽管您声明您想要一个 FORWARD):
In order to do this you may also need to set the filter to run on FORWARD (and INCLUDE as your code shows, although you state you want a FORWARD):
<filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> <dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> <dispatcher>INCLUDE</dispatcher> <!-- If you want includes as well --> </filter-mapping>
