基于SSM框架的简易的分页功能——包含maven项目的搭建

　　新人第一次发帖，有什么不对的地方请多多指教~~

　　　　分页这个功能经常会被使用到，我之前学习的时候找了很多资源，可都看不懂（笨死算了），最后还是在朋友帮助下做出了这个分页。我现在把我所能想到的知识

　　做了一个整理发上来，供大家参考参考，希望能帮助到一些和我一样的人吧@.@ 中间肯定有很多没有表述明白，请多多见谅，博主刚刚结束java 四个月，小白一只，

　　还望海涵~~~

　　前面八步为项目准备工作，如果maven项目搭建完成的可以跳过~

　　最后面有附件，是完整的一个工程，包含数据库的呦

首先需要一个IDEA！

　　我使用的是ideaIU-2016.2 下载地址：http://www.jetbrains.com/idea/download/#section=windows

　　IDEA常用配置：http://blog.csdn.net/yelove1990/article/details/51541327

然后创建一个maven项目

　　一、Create New Project 创建项目

　　二、选择maven项目并按指示创建

　　三、GroupId是项目组织唯一的标识符，实际对应JAVA的包的结构，是main目录里java的目录结构。

　　　　ArtifactId是项目唯一的标识符，实际对应项目的名称，就是项目根目录的名称。

　　　　一般GroupId就是填xxx.xx.xxx类似这样的。

　　四、这里需要添加一条参数，Name是划线左边的名称，value是划线右边的值，相应的填写进去就行，然后点OK-Next

　　五、创建工程，工程名为前面的ArtifactId

　　六、然后IDEA就会自动创建项目

　　　　创建完成会有BUILD SUCCESS的字样提示，表示创建成功。

　　七、目录结构like this

　　八、添加maven依赖太多了，不一一解释了，教程网址：http://www.yiibai.com/maven/

　　　　直接复制粘贴到自己的maven中即可。

接下来是正文部分！

　　首先需要一个分页工具类(Page)，和实体类(Record)，包装类(seeRecord)。中间内容基本不需要改动，您可以根据需要改动每页显示的记录条数。

  1 package po;
  2 
  3 import java.io.Serializable;
  4 
  5 public class Page implements Serializable{
  6 
  7     private static final long serialVersionUID = -3198048449643774660L;
  8 
  9     private int pageNow = 1; // 当前页数
 10 
 11     private int pageSize = 5; // 每页显示记录的条数
 12 
 13     private int totalCount; // 总的记录条数
 14 
 15     private int totalPageCount; // 总的页数
 16 
 17     @SuppressWarnings("unused")
 18     private int startPos; // 开始位置，从0开始
 19 
 20     @SuppressWarnings("unused")
 21     private boolean hasFirst;// 是否有首页
 22 
 23     @SuppressWarnings("unused")
 24     private boolean hasPre;// 是否有前一页
 25 
 26     @SuppressWarnings("unused")
 27     private boolean hasNext;// 是否有下一页
 28 
 29     @SuppressWarnings("unused")
 30     private boolean hasLast;// 是否有最后一页
 31 
 32     /**
 33      * 通过构造函数 传入  总记录数  和  当前页
 34      * @param totalCount
 35      * @param pageNow
 36      */
 37     public Page(int totalCount, int pageNow) {
 38         this.totalCount = totalCount;
 39         this.pageNow = pageNow;
 40     }
 41 
 42     /**
 43      * 取得总页数，总页数=总记录数/总页数
 44      * @return
 45      */
 46     public int getTotalPageCount() {
 47         totalPageCount = getTotalCount() / getPageSize();
 48         return (totalCount % pageSize == 0) ? totalPageCount
 49                 : totalPageCount + 1;
 50     }
 51 
 52     public void setTotalPageCount(int totalPageCount) {
 53         this.totalPageCount = totalPageCount;
 54     }
 55 
 56     public int getPageNow() {
 57         return pageNow;
 58     }
 59 
 60     public void setPageNow(int pageNow) {
 61         this.pageNow = pageNow;
 62     }
 63 
 64     public int getPageSize() {
 65         return pageSize;
 66     }
 67 
 68     public void setPageSize(int pageSize) {
 69         this.pageSize = pageSize;
 70     }
 71 
 72     public int getTotalCount() {
 73         return totalCount;
 74     }
 75 
 76     public void setTotalCount(int totalCount) {
 77         this.totalCount = totalCount;
 78     }
 79     /**
 80      * 取得选择记录的初始位置
 81      * @return
 82      */
 83     public int getStartPos() {
 84         return (pageNow - 1) * pageSize;
 85     }
 86 
 87     public void setStartPos(int startPos) {
 88         this.startPos = startPos;
 89     }
 90 
 91     /**
 92      * 是否是第一页
 93      * @return
 94      */
 95     public boolean isHasFirst() {
 96         return (pageNow == 1) ? false : true;
 97     }
 98 
 99     public void setHasFirst(boolean hasFirst) {
100         this.hasFirst = hasFirst;
101     }
102     /**
103      * 是否有首页
104      * @return
105      */
106     public boolean isHasPre() {
107         // 如果有首页就有前一页，因为有首页就不是第一页
108         return isHasFirst() ? true : false;
109     }
110 
111     public void setHasPre(boolean hasPre) {
112         this.hasPre = hasPre;
113     }
114     /**
115      * 是否有下一页
116      * @return
117      */
118     public boolean isHasNext() {
119         // 如果有尾页就有下一页，因为有尾页表明不是最后一页
120         return isHasLast() ? true : false;
121     }
122 
123     public void setHasNext(boolean hasNext) {
124         this.hasNext = hasNext;
125     }
126     /**
127      * 是否有尾页
128      * @return
129      */
130     public boolean isHasLast() {
131         // 如果不是最后一页就有尾页
132         return (pageNow == getTotalCount()) ? false : true;
133     }
134 
135     public void setHasLast(boolean hasLast) {
136         this.hasLast = hasLast;
137     }
138 
139 }

page工具类

package po;

public class SeeRecord {

    /*当前登录的用户名*/
    private String loginName;

    /*分页对象*/
    private Page page;

    public String getLoginName() {
        return loginName;
    }

    public void setLoginName(String loginName) {
        this.loginName = loginName;
    }

    public Page getPage() {
        return page;
    }

    public void setPage(Page page) {
        this.page = page;
    }
}

seeRecord

package po;

public class Record {
    private int nub;
    private String username;
    private String loginName;
    private String days;
    private String business;
    private String note;

    public int getNub() {
        return nub;
    }

    public void setNub(int nub) {
        this.nub = nub;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getLoginName() {
        return loginName;
    }

    public void setLoginName(String loginName) {
        this.loginName = loginName;
    }

    public String getDays() {
        return days;
    }

    public void setDays(String days) {
        this.days = days;
    }

    public String getBusiness() {
        return business;
    }

    public void setBusiness(String business) {
        this.business = business;
    }

    public String getNote() {
        return note;
    }

    public void setNote(String note) {
        this.note = note;
    }
}

Record

　　然后编写Mybatis的Recordmapper.xml配置文件，编写sql语句

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" 
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >

<mapper namespace="ssm.dao.RecordDao" ><!--对应相应的DAO接口-->
    <!--查询操作记录-->
    <select id="queryAllRecord" parameterType="ssm.po.SeeRecord" resultType="ssm.po.Record">
        SELECT * FROM record WHERE loginName = #{loginName} limit #{page.startPos},#{page.pageSize}<!--startPos开始页 ， pageSize每页显示的记录条数-->
    </select>

    <!--查询总记录条数-->
    <select id="getCount" resultType="int" parameterType="String">
        select count(*) from record where loginName = #{value}
    </select>
</mapper>

　　接下来编写Dao接口（RecordDao）

package Dao;

import org.springframework.stereotype.Repository;
import po.Record;
import po.SeeRecord;
import java.util.List;

@Repository
public interface RecordDao {
    /*取得操作记录*/
    List<Record> queryAllRecord(SeeRecord seeRecord);

    /*取得记录条数信息，通过当前用户的loginName查询*/
    int getCount(String loginName);
}

　　接口编写完成后需要慌里面传值，此时就需要编写Controller。

　　　　先获取到当前页和用户名，然后调用DAO接口查询数据库，获得总记录条数，把总记录条数和当前页传入到page的构造方法中，page工具类会根据传入的参数，算出共几页。然后查出当前用户的所有操作记录，存到recordList中并返回给页面，页面就可以显示了。

package controller;

import Dao.RecordDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import po.Page;
import po.Record;
import po.SeeRecord;


import javax.servlet.http.HttpServletRequest;
import java.util.List;

@Controller
public class RecordController {

    @Autowired
    private RecordDao recordDao;

    /*查看操作记录*/
    @RequestMapping("/queryAll")
    public String record(String loginName , Model model, SeeRecord seeRecord, String pageNow){
        String user_Name;
        Page page = null;//new 对象在下面
        user_Name = loginName;//获取当前登录的用户的loginName
        int totalCount = recordDao.getCount(user_Name);//获取当前用户总记录条数
        if(pageNow != null && pageNow != "") {//防止出现空指针异常
            int pageNow1 = Integer.parseInt(pageNow);
            page = new Page(totalCount, pageNow1);//这样写的好处，判断完成外面可以继续调用
        }
        seeRecord.setLoginName(user_Name);
        seeRecord.setPage(page);
        List<Record> recordList = recordDao.queryAllRecord(seeRecord);//取得当前用户的所有操作记录
        model.addAttribute("page",page);
        model.addAttribute("recordList",recordList);
        return "recordPage";
    }
}

编写jsp页面接收并显示。

由于测试需要，我加了一个跳转页面。向Controller中传入了两个值，pageNow和loginName，表示当前登录的用户和当前的页数。

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>用于跳转到分页页面</title>
</head>
<body>
    <form action="/queryAll?pageNow=1&loginName='ceshiyong01'" method="post">
        <input type="submit" value="查看操作记录" style=" 100px; height: 30px;"/>
    </form>
</body>
</html>

　　分页功能显示页面：

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<html>
<head>
    <title>操作记录</title>
    <style type="text/css">
        body{
            margin: 0px;
            padding: 0px;
        }
        table{
            width: 100%;
            height: 400px;
            border: #000 1px solid;
        }
        tr td{
            height: 40px;
            text-align: center;
            border: #000 1px solid;
        }

    </style>
</head>
<body>
    <div style="100px; height: 30px; margin: 10px auto;line-height: 30px;">
        <strong><font style="size:36px;">操作记录</font></strong>
    </div>
    <table>
        <tr>
            <td width="70px">流水号</td>
            <td width="90px">姓名</td>

        </tr>
        <!--循环遍历所有得到的记录并输出-->
        <c:forEach items="${recordList}" var="record">

　　web.xml: 这里有个问题，创建完maven项目自动生成的web.xml头部版本可能是2.3左右的，如果版本低于2.4，会导致jsp页面的EL表达式失效。只要把头部改到2.4以上即可。
