action获取ValueStack中的值

HttpServletRequest request = ServletActionContext.getRequest(); ValueStack vs = (ValueStack)request.getAttribute("struts.valueStack"); String username = vs.findValue("username").toString();

或：

ValueStack vs = ActionContext.getContext().getValueStack(); System.out.println("#############################"); System.out.println(vs.findValue("username").toString()); System.out.println("#############################");
