struts的ActionRedirect类

ActionRedirect类时ActionForward的子类，所以在项目当中也可以使用ActionRedirect类来进行action请求的转发。但是它有一个好处就是在转发时可以对路径进行动态的添加参数：

public ActionForward execute(ActionMapping mapping,                              ActionForm form,                              HttpServletRequest request,                              HttpServletResponse response)         throws Exception {     ActionRedirect redirect =             new ActionRedirect(mapping.findForward("doRedirect"));     redirect.addParameter("param1","value1");     redirect.addParameter("param2","2");     redirect.addParameter("param3","3.0");     return redirect; }
