新的struts分页

1.jsp页面

<table id="tablelist" class="table table-striped table-bordered table-hover">
                                    <thead>
                                        <tr>
                                            <th>通知类型</th>
                                            <th>内容</th>
                                            <th>通知时间</th>
                                            <th>是否已读</th>
                                        </tr>
                                        <c:forEach items="${pager.lists}" var="item">
                                            <tr>

                                                <td>${item.texts}</td>
                                                <td>${item.strNotTime}</td>
                                                <td>

                                                    已读
                                                    </c:if>
                                                </td>
                                            </tr>
                                        
                                         </c:forEach>
                                        
                                        
                                    </thead>
    
                                    <tbody id="fora">
                                        

                                    </tbody>

                                </table>

                                <style type="text/css">
            a {
                color: #555555;
                text-decoration: none;
                cursor: pointer;
            }
            .pages a.p_pre:hover {
                background-color: #eaeaea;
                color: #555555;
                border: 1px solid #cccccc;
            }
            .pages a {
                height: 36px;
                line-height: 36px;
                overflow: hidden;
                color: #666666;
                font-size: 16px;
                text-align: center;

                border: 1px solid #cccccc;
                -webkit-border-radius: 2px;
                -moz-border-radius: 2px;
                border-radius: 2px;
            }

            .pages a:hover, .pages a.cur {
                color: #FFF;
                background-color: #DD4E62;
                border: 1px solid #DD4E62;
            }

        </style>
        <div class="pages">
            <c:if test="${pager.totalPage>=1}">
                <a href="${pageContext.request.contextPath}${pager.url}&pageIndex=1" class="p_pre">首页</a>
                <c:if test="${pager.pageIndex>1}">
                    <a href="${pageContext.request.contextPath}${pager.url}&pageIndex=${pager.pageIndex-1}" class="p_pre">上一页</a>
                </c:if>
                <c:forEach  var="temp" begin="${pager.pageIndex>3?pager.pageIndex-3:1}" end="${pager.totalPage-pager.pageIndex>3?pager.pageIndex+3:pager.totalPage}" step="1">
                    <c:if test="${pager.pageIndex==temp}">
                        <a href="${pageContext.request.contextPath}${pager.url}&pageIndex=${temp}" class="cur">${temp}</a>

                <a href="#" class="cur">暂无记录</a>
            </c:if>
        </div>

需要注意记得引入el和jstl

isELIgnored="false"
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

2.bin的注入

    <bean id="noticepage" scope="prototype" class="com.dawn.action.AdminNoticeAction">
        <property name="noticeDAO" ref="noticeDAO" /> 
    </bean>

3.struts2的配置

        <action name="noticepage" class="noticepage" method="noticepage">
            <result name="success">note.jsp</result>
            <result name="login" type="redirect">login.jsp</result>
        </action>

4.struts action的书写

package com.dawn.action;

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

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.apache.struts2.ServletActionContext;
import org.apache.struts2.interceptor.SessionAware;

import com.opensymphony.xwork2.ActionSupport;
import com.dawn.dao.NoticeDAO;
import com.dawn.model.Admin;
import com.dawn.model.Notice;
import com.dawn.util.PagerInfo;

public class AdminNoticeAction extends ActionSupport{
    private NoticeDAO noticeDAO;
    
    private Map<String, Object> session;
    private Integer pageIndex;
    private Integer id;

    /**
     * @return the noticeDAO
     */
    public NoticeDAO getNoticeDAO() {
        return noticeDAO;
    }

    /**
     * @param noticeDAO the noticeDAO to set
     */
    public void setNoticeDAO(NoticeDAO noticeDAO) {
        this.noticeDAO = noticeDAO;
    }
    
    

    
    
    

    /**
     * @return the pageIndex
     */
    public Integer getPageIndex() {
        return pageIndex;
    }

    /**
     * @param pageIndex the pageIndex to set
     */
    public void setPageIndex(Integer pageIndex) {
        this.pageIndex = pageIndex;
    }

    public String noticepage(){
        HttpServletRequest request = ServletActionContext.getRequest();
        HttpSession session = request.getSession();
        Admin admin = (Admin)session.getAttribute("admin");
        //设置当前页码，第一次进入为第一页
        int index2=pageIndex==null?1:pageIndex;
        //创建分页工具类
        PagerInfo<Notice> pager=new PagerInfo<Notice>();
        //保存当前页码
        pager.setPageIndex(index2);
        //保存每页行数
        pager.setPageSize(5);
        //给登陆的人的id
        if(admin!=null&&admin.getId()!=0&&admin.getId()!=null){
            id=admin.getId();
        }
        //dao层查询数据集合
        List<Notice> queryAll = noticeDAO.queryAll(pager, id);
        //给pager扔查询出来的集合
        pager.setLists(queryAll);
        //获取总数
        Integer totalSize = noticeDAO.pageAll(id);
        //保存到page里
        pager.setTotalSize(totalSize);

        pager.setUrl("/noticepage.action?id="+id);
        
        session.setAttribute("pager", pager);
        return SUCCESS;
        
    }

    

}
