对用Strust1实现页面跳转的小总结

xiaoxiao2021-02-27 361

页面跳转的总流程为：

1、根据自己命名的URL ：http://localhost:7001/ecs_local/public/threeBBOnlineVas/threeBBOnlineVasService.do?lang=zh-HK&method=init

它会根据threeBBonlineVasService.do去找到ThreeBBOlineVasAction这个Action类,然后根据method=init去匹配执行这个Action类的init()函数

2、在init函数中执行到return mapping.findForward("select");这一句就会到配置文件struts-config.xml这里面找到匹配"select"这个字符串跳到默认的主页3BB_LeSportsNBA_Select.jsp这里来。

3、在3BB_LeSportsNBA_Select.jsp这个页面中写上关键的一句<input type="hidden" name="method" value="SelectAccount" />

然后提交from表单到Action类threeBBOnlineVasService.do这个中去，进入Action后它会根据这个字符串"SelectAccount"去匹配

执行对应的函数SelectAccount()。

4、之后又和上面一样执行到return mapping.findForward("SelectAccount");这一句后，就会到配置文件struts-config.xml这里面找到匹配跳到下一个页面3BB_LeSportsNBA_SelectAccount.jsp这里来。之后以此类推。

具体实现代码如下：

1、ThreeBBOlineVasAction.java

package com.hgc.ecs.web.threeBBOnlineVas.action; import java.util.ArrayList; import java.util.List; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.apache.struts.action.ActionForm; import org.apache.struts.action.ActionForward; import org.apache.struts.action.ActionMapping; import org.apache.struts.actions.DispatchAction; import com.hgc.ecs.web.onlineVas.dao.CreateVASOrderDAO; import com.hgc.ecs.web.onlineVas.service.CreateVASOrderService; import com.hgc.ecs.web.threeBBOnlineVas.bean.loginMessage; import com.hgc.ecs.web.threeBBOnlineVas.util.GetLoginMessage; public class ThreeBBOlineVasAction extends DispatchAction { private final Log log = LogFactory.getLog(ThreeBBOlineVasAction.class); int a = 0; int b = 0; int c = 0; /* * public ActionForward execute(ActionMapping mapping, ActionForm * actionForm, HttpServletRequest request, HttpServletResponse response) * throws Exception { * * String page = request.getParameter("type"); * * if ("SelectAccount".equals(page)) { return mapping.findForward(page); } * return mapping.findForward("SelectAccount"); } */ public ActionForward init(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { this.log.info("Comging Home Page ..."); return mapping.findForward("select"); } public ActionForward SelectAccount(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { String Name = request.getParameter("hiddenName"); String Number = request.getParameter("hiddenNumber"); String MobileNumber = request.getParameter("hiddenphoneNumber"); List<loginMessage> resultList = new ArrayList<loginMessage>(); String sign, servType, acctNo, contNo, acctStat, contStat, subNo, contractEndDate, totalAmntDue, custName; this.log.info("Name:" + Name + "-------" + Number + "----------" + MobileNumber); GetLoginMessage gm = new GetLoginMessage(); resultList = gm.getLoginMessage(Number, Name); sign = resultList.get(0).getSign(); request.setAttribute("result", resultList); response.setContentType("text/html;charset=UTF-8"); request.setCharacterEncoding("UTF-8"); // 不符合资格的在前台不允许跳到下个页面并且弹框提示 if (sign.equals("false")) { return mapping.findForward("select2"); } return mapping.findForward("SelectAccount"); } public ActionForward comfirm(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { return mapping.findForward("comfirm"); } public ActionForward complete(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { String strAccountNo = request.getParameter("accountNumber"); String strAcctNo = ""; String strContNo = ""; if (strAccountNo != null && strAccountNo != "") { strAcctNo = strAccountNo.substring(0, 8); strContNo = strAccountNo.substring(8, 11); } String strOfferId = request.getParameter("offerid"); String strSmsCode = request.getParameter("hiddenphoneNumber"); String sale_code = request.getParameter("sale_code"); CreateVASOrderService service = new CreateVASOrderService(); String strResult = service.Inert(strAcctNo, strContNo, strOfferId, strSmsCode, sale_code); if (strResult != "") { return mapping.findForward("complete"); } else { return mapping.findForward("complete"); } } }

2、struts-config.xml

<action parameter="method" path="/public/threeBBOnlineVas/threeBBOnlineVasService" type="com.hgc.ecs.web.threeBBOnlineVas.action.ThreeBBOlineVasAction" scope="request"> <forward name="select" path="/OnlineVas_3BB/3BB_LeSportsNBA_Select.jsp" /> <forward name="select2" path="/OnlineVas_3BB/3BB_LeSportsNBA_Select.jsp?type=error" /> <forward name="comfirm" path="/OnlineVas_3BB/3BB_LeSportsNBA_Confirm.jsp" /> <forward name="SelectAccount" path="/OnlineVas_3BB/3BB_LeSportsNBA_SelectAccount.jsp" /> <forward name="comfirm2" path="/OnlineVas_3BB/3BB_LeSportsNBA_Confirm.jsp?type=error" /> <forward name="complete" path="/OnlineVas_3BB/3BB_LeSportsNBA_Complete.jsp" /> <forward name="sspselect" path="/OnlineVas_3BB/3BB_LeSportsNBA_Select.jsp" /> <forward name="sspcomfirm" path="/OnlineVas_3BB/3BB_LeSportsSSP_Confirm.jsp" /> <forward name="sspcomfirm2" path="/OnlineVas_3BB/3BB_LeSportsSSP_Confirm.jsp?type=error" /> <forward name="sspcomplete" path="/OnlineVas_3BB/3BB_LeSportsSSP_Complete.jsp" /> </action>

3、3BB_LeSportsNBA_Select.jsp
