loginaction.java

这是我平时做练习的翻页源码

package com.dj.action;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import com.dj.dao.PageIF;
import com.dj.dao.PageSql;
import com.dj.db.ResultSetCache;
import com.dj.form.PageForm;
import com.dj.service.ServiceFactpry;
import com.dj.vo.Student;

public class LoginAction extends Action {

	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		
		PageForm pf = (PageForm) form;
		/** 封装分页用的form和当前页的数据 **/
		Map map = ServiceFactpry.getPageIF().init(PageSql.strPageSql, pf,
				PageSql.strId);
		/**获取map中的当前页数据 **/
		ResultSetCache res=(ResultSetCache) map.get(PageIF.pageRes);
		List list=ServiceFactpry.getQueryListIF().getList(res);
		/** 初始化分页用的form **/
		pf=(PageForm) map.get(PageIF.pageForm);
		/** 将list放入request中 **/
		request.setAttribute("list", list);
		
		return mapping.findForward("success");
	}
