spring mvc +bootstrap+datatable实现分页

文章介绍大致分以下几步：
1. 后台数据分页查询实现；
2. 前台bootstrap样式+datatable插件 数据渲染；

一、后台真分页实现：
主要涉及以下内容：
1、数据库分页插件类PagePlugin.java；
2、分页参数类Page.java；
3、排序类SortCond.java；
4、用来返回datatables格式数据的DataTables.java(不使用datatables时不需要)；
5、mybatis-config.xml配置插件；
6、相关mapper.xml文件SQL；
7、controller层参数传递；
直接上代码：

            sb.append("}\n");

            // 跳转函数
            sb.append("function toTZ(){");
            sb.append("var toPaggeVlue = document.getElementById(\"toGoPage\").value;");

    public void setPageStr(String pageStr) {

    public int getShowCount() {

    public void setShowCount(int showCount) {

        this.showCount = showCount;

    public int getCurrentResult() {
        currentResult = (getCurrentPage() - 1) * getShowCount();
        if (currentResult < 0)
            currentResult = 0;

    }

    public PageData getPd() {
        return pd;
    }

    public void setPd(PageData pd) {
        this.pd = pd;
    }

}

3、SortCond.java

package com.bi.common.base.entity;

/** * <p>功能描述：排序类</p> * <p>Company: </p> * @author Jeff * @version 1.0 2015年12月11日 */
public class SortCond {
    /** * 排序类型枚举 */
    public enum Order {
        ASC, DESC
    }

    /** * 排序类型 */
    private String column;

    /** * 排序类型 */
    private Order order;

    public SortCond(String column) {
        this(column, Order.DESC);
    }

    public SortCond(String column, Order order) {
        this.column = column;
        this.order = order;
    }

    public String getColumn() {
        return column;
    }

    public Order getOrder() {
        return order;
    }
}

4、DataTables.java

/** * 文件名: DataTables.java * 版 权: Copyright © 2013 - 2015 ThinkJF, Inc. All Rights Reserved * 描 述: <描述> * 创建人: Jeff * 创建时间: 2015年12月10日 */
package com.bi.common.base.entity;

import java.io.Serializable;
import java.util.List;

import org.apache.poi.ss.formula.functions.T;

/** * <p>功能描述：datatables数据返回实体类</p> * <p>Company: 上海丞风智能科技有限公司</p> * @author Jeff * @version 1.0 2015年12月10日 */
public class DataTables<T> implements Serializable{

    private static final long serialVersionUID = 8172262630982712326L;
    //与datatales 加载的“dataSrc"对应 
    private List<T> data; 
    //过滤后的记录数
    private int recordsFiltered;   
    //数据库里总共记录数
    private int recordsTotal;
    //请求次数计数器
    private int draw;

    private Boolean success;


    public List<T> getData() {
        return data;
    }
    public void setData(List<T> data) {
        this.data = data;
    }
    public int getRecordsFiltered() {
        return recordsFiltered;
    }
    public void setRecordsFiltered(int recordsFiltered) {
        this.recordsFiltered = recordsFiltered;
    }
    public int getRecordsTotal() {
        return recordsTotal;
    }
    public void setRecordsTotal(int recordsTotal) {
        this.recordsTotal = recordsTotal;
    }
    public int getDraw() {
        return draw;
    }
    public void setDraw(int draw) {
        this.draw = draw;
    }



}

5、mybatis-config.xml配置插件
指定方言为mysql，且配置sqlid以_page结尾的都走分页查询

    <plugins>
        <plugin interceptor="com.bi.dao.base.plugin.PagePlugin">
            <property name="dialect" value="mysql"/>
            <property name="pageSqlId" value=".*_page"/>
        </plugin>
    </plugins>

6、相关mapper.xml文件SQL
拿查询用户列表来举例：

    <sql id="userSort">
         <if test="pd.sortCond != null and pd.sortCond.size() != 0">
                order by
                <foreach collection="pd.sortCond" item="sortCond" separator=",">
                    ${sortCond.column} ${sortCond.order}
                </foreach>
         </if>  
    </sql>
    <select id="listAllUser_page" parameterType="Page" resultMap="userResultMap" useCache="false">
        select  u.USER_ID,
                u.USER_NAME,
                u.USER_PWD,
                u.USER_SEX,
                u.USER_ADDRESS,
                u.E_MAIL,
                u.USER_PHOTO,
                u.USER_PHONE,
                u.DEPT_ID,
                u.USER_STATUS,
                u.CREATE_BY,
                u.CREATE_TIME,
                u.LAST_LOGIN_TIME,
                u.SKIN 
        from BI_SYS_USER u
        where u.USER_NAME != 'admin'
        <if test="pd.userName != null and pd.userName != ''"><!-- 关键词检索 -->
            and u.USER_NAME LIKE CONCAT(CONCAT('%', #{pd.userName}),'%')
        </if>
        <if test="pd.userPhone != null and pd.userPhone != ''"><!-- 手机号码检索 -->
            and u.USER_PHONE=#{pd.userPhone} 
        </if>
        <if test="pd.deptId!=null and pd.deptId!=''"><!-- 部门检索 -->
            and u.DEPT_ID = #{pd.deptId} 
        </if>
        <if test="pd.userStatus!=null and pd.userStatus!=''"><!-- 用户状态检索 -->
            and u.USER_STATUS = #{pd.userStatus} 
        </if>
        <include refid="userSort"></include>
    </select>

7、controller类部分代码：

    @RequestMapping(value="/userSearch")
    @ResponseBody
    public Object userSearch(Page page){
        PageData pd = new PageData();
        pd = this.getPageData();
        page.setPd(pd);

        //调用封装方法，构造page参数
        page = DataTablesUtil.constructPd(page);
        //构造分页查询param------end------------
        //分页查询（查询SQL id必须以"_page"结尾）
        List<User>  userList = userService.listAllUser_page(page);

        //设置datatables要求返回的数据-----start-------
        /** * draw:请求次数计数器 要求原样返回 * Data:查询结果List * recordsTotal:查询结果总数 * recordsFiltered:过滤条件后的结果总数（一般与查询结果总数一致） */
        DataTables<User> dts = new DataTables();
        dts.setDraw(Integer.parseInt(pd.get("draw").toString()));
        dts.setData(userList);
        dts.setRecordsTotal(page.getTotalResult());
        dts.setRecordsFiltered(page.getTotalResult());
        //设置datatables要求返回的数据-----end-------

        return dts;
    }

8、补充一个DataTablesUtil.java
主要实现将前端传过来的参数处理后构造好Page类供查询service方法使用。

/** * 文件名: DataTablesUtil.java * 版 权: Copyright © 2013 - 2015 ThinkJF, Inc. All Rights Reserved * 描 述: <描述> * 创建人: Jeff * 创建时间: 2015年12月11日 */
package com.bi.common.util;

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

import com.bi.common.base.entity.Page;
import com.bi.common.base.entity.SortCond;

/** * <p> * 功能描述：dataTables工具类 * </p> * <p> * Company: * </p> * * @author Jeff * @version 1.0 2015年12月11日 */
public class DataTablesUtil {

    /** * 构造Page类，包括设置startIndex,pageSize以及pd对象的查询参数及排序参数 * @author Jeff * @version 1.0 2015年12月11日 * @param page * @return */
    public static Page constructPd(Page page) {
        PageData pd = new PageData();
        pd = page.getPd();
        // 获取前端datatables参数---------start--------------
        // desc:draw,start,length
        // 计数器
        int draw = Integer.parseInt(pd.get("draw").toString());
        // 数据起始位置
        int startIndex = Integer.parseInt(pd.get("startIndex").toString());
        // 数据长度
        int pageSize = Integer.parseInt(pd.get("pageSize").toString());
        // 根据列索引获取该列列名
        String ColumnName = pd.getString("sortName");
        // 是降序还是升序
        String sortDir = pd.getString("sortDir");
        // 获取前端参数---------end--------------

        // 构造分页查询param------start------------
        // desc:pageSize,currentResult,sortCond
        page.setShowCount(pageSize);
        page.setCurrentResult(startIndex);
        // 排序设置
        if (ColumnName != null && !"".equals(ColumnName)) {
            List<SortCond> lsc = new ArrayList<SortCond>();
            SortCond sc = new SortCond(ColumnName,
                    "asc".equals(sortDir) ? SortCond.Order.ASC
                            : SortCond.Order.DESC);
            lsc.add(sc);
            pd.put("sortCond", lsc);
        }
        //将设置覆盖原pd
        page.setPd(pd);

        return page;
    }

}

二、前台bootstrap样式+datatable插件 数据渲染；
涉及到以下内容：
1、bootstrap与datatables相关css与js;
2、构造dataTables相关对象，设置相关参数；
3、html代码

1、css与js,可以直接上官网扒
dataTables.bootstrap.min.css
buttons.bootstrap.min.css
select.bootstrap.min.css
editor.bootstrap.min.css

jquery.dataTables.min.js
dataTables.bootstrap.min.js
dataTables.buttons.min.js
buttons.bootstrap.min.js
dataTables.select.min.js
dataTables.editor.min.js
editor.bootstrap.min.js

2、构造dataTables相关对象，设置相关参数

<script type="text/javascript"> //声明biUserManage对象 var biUserManage = { userTable : null, getQueryCondition : function(data) { var param = {}; //处理datatables排序参数 if (data.order&&data.order.length&&data.order[0]) { var indexColumn = data.order[0].column; param.sortName = data.columns[indexColumn].name; param.sortDir = data.order[0].dir; } //处理查询参数 param.userName = $("#searchUserName").val(); param.userPhone = $("#searchPhone").val(); param.deptId = $("#searchDeptId").val(); param.userStatus = $("#searchStatus").val(); //处理分页参数 param.startIndex = data.start; param.pageSize = data.length; param.draw = data.draw; return param; } }; //初始化datatables  $(function(){ biUserManage.userTable = $('#usertable').dataTable($.extend({ //设置ajax数据源请求 ajax: function(data, callback){ //封装请求参数 var param = biUserManage.getQueryCondition(data); $.ajax({ type: "POST", url: "${rc.contextPath}/user/userSearch?systime=" + new Date().getTime(), data: param, dataType: "json", success: function(result) { callback(result); }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert("查询失败"); //$('#div-table-container').spinModal(false); } }); }, //默认按哪列排序 order: [ 9, 'desc' ], //设置列相关信息 columns: [//列定义参数 CONSTANT.DATA_TABLES.CELL_CHECKBOX, { "data": "userId", "name": "USER_ID" }, { "data": "userName", "name": "USER_NAME" }, { "data" : "userSex", "name": "USER_SEX", "width" : "80px", "render" : function(data,type, row, meta) { if(data==1){ return '<i class="fa fa-male"></i> 男'; }else{ return '<i class="fa fa-female"></i> 女'; } }, "orderable" : false }, { "data":"email", "name": "E_MAIL", "orderable" : false }, { "data":"userPhone", "name": "USER_PHONE", "orderable" : false }, { "data":"dept.deptName", "name": "DEPT_ID" }, { "data": "userAddress", "name": "USER_ADDRESS", "orderable" : false }, { "data" : "userStatus", "name": "USER_STATUS", "width" : "80px", "render" : function(data,type, row, meta) { if(data==0){ return "注销"; }else if(data==1){ return "正常"; }else if(data==2){ return "暂停"; } } }, { "data": "lastLoginTime", "name": "LAST_LOGIN_TIME", "width" : "120px" }, { "data": null, "width" : "80px", "defaultContent":"", "orderable" : false } ], //在最后一列增加编辑删除按钮  "createdRow": function ( row, data, index ) { //行渲染回调,在这里可以对该行dom元素进行任何操作 $('td', row).eq(10).addClass("taC"); var btnEdit = $('<div class="userM-table-function"><a class="fa fa-pencil-square text-success"></a><div class="line"></div><a class="fa fa-trash text-danger"></a></div>'); $('td', row).eq(10).append(btnEdit); } },CONSTANT.DATA_TABLES.DEFAULT_OPTION)).api(); }); //初始化其它  $(function(){ //加载搜索按钮点击事件 $("#btnSearch").click(function(){ biUserManage.isSearch = true; biUserManage.userTable.ajax.reload(); }); }); /*常量*/ var CONSTANT = { DATA_TABLES : { DEFAULT_OPTION : { //DataTables初始化选项 "language": { "sProcessing": "处理中...", "sLengthMenu": "每页 _MENU_ 项", "sZeroRecords": "没有匹配结果", "sInfo": "当前显示第 _START_ 至 _END_ 项，共 _TOTAL_ 项。", "sInfoEmpty": "当前显示第 0 至 0 项，共 0 项", "sInfoFiltered": "(由 _MAX_ 项结果过滤)", "sInfoPostFix": "", "sSearch": "搜索:", "sUrl": "", "sEmptyTable": "表中数据为空", "sLoadingRecords": "载入中...", "sInfoThousands": ",", "oPaginate": { "sFirst": "首页", "sPrevious": "上页", "sNext": "下页", "sLast": "末页", "sJump": "跳转" }, "oAria": { "sSortAscending": ": 以升序排列此列", "sSortDescending": ": 以降序排列此列" } }, "processing" : false, //隐藏加载提示,自行处理 "serverSide" : true, "searching" : false,//禁用表格内搜索 "lengthMenu" :[10,20,50,100]//定义页面长度组件里面的选项 }, CELL_CHECKBOX : { //复选框单元格 "className" : "cell-chechbox", "orderable" : false, "data": null, "width" : "40px", "render" : function(data, type, row, meta) { return '<input type="checkbox" >'; } } } }; </script>

3、html代码

<table class="table table-bordered table-hover " id="usertable">
                <thead>
                    <tr>
                        <th class="taC resource-content-check"><input type="checkbox" class="check" id="allcheck" /></th>
                        <th class="taC cp" width="5%">编号</th>
                        <th class="taC cp" width="10%">姓名</th>
                        <th class="taC cp" width="5%">性别</th>
                        <th class="taC cp" width="10%">邮箱</th>
                        <th class="taC cp" width="10%">联系电话</th>
                        <th class="taC cp" width="10%">所属部门</th>
                        <th class="taC cp" width="15%">地址</th>
                        <th class="taC" width="5%">状态</th>
                        <th class="taC" width="18%">最后登录时间</th>
                        <th class="taC" width="10%">操作</th>
                    </tr>
                </thead>

            </table>

截止到这里，基本上整个代码都差不多贴完了，大家可以根据自己的项目实际情况进行修改；
这里可能还涉及一个前端与后台用json格式传递数据的问题，可以参照我关于这个问题的文章处理。
