一段很有意义的源码,看了就知道,不信试一试啊!

package com.wondersgroup.basemodule.messagemanage.web.Action;

import com.wondersgroup.basemodule.messagemanage.dao.impl.BaseMessageDAOImpl;

public class ViewMessageAction extends Action {
	public ActionForward perform(ActionMapping actionMapping,
			ActionForm actionForm, HttpServletRequest httpServletRequest,
			HttpServletResponse httpServletResponse) {

		String messageId = httpServletRequest.getParameter("messageId");//从页面得到消息ID;
		
		/** 
		 *  viewType页面传递参数,表示查看类型；
		 *  viewType值："allReceive"（所有接收的消息）；"noAnswer"（未回复消息）；
		 */
		String viewType = httpServletRequest.getParameter("viewType");
		
		BaseMessageDAOImpl query = new BaseMessageDAOImpl();
		List li = query.findByLike("MSG_ID", messageId);
		httpServletRequest.setAttribute("view", li);
		ActionForward forward = actionMapping.findForward("viewSendMessage");//转 发送消息view

		}

		{
			forward = actionMapping.findForward("noAnswerMessage");//转未回复消息view
		}
		return forward;
