Datatable+Springmvc+mybatis(分页+排序+搜索)_Jquery

一、简介

通过Jqury的Datatable插件，构造数据列表，并且增加或者隐藏相应的列，已达到数据显示要求。同时， jQuery Datatable 强大的功能支持：排序，分页，搜索等。

二、前台分页

1、Datatable参数讲解

 <div class="container-fluid margin-md">
                <table id="firm-list" class="table table-responsive table-hover table-bordered">
                    <thead>
                        <tr>
                            <th>订单号</th>
                            <th>校区</th>
                            <th>下单时间</th>
                            <th>发单人</th>
                            <th>带客</th>
                            <th>订单状态</th>
                            <th>订单类型</th>
                            <th>金额</th>
                            <th>操作</th>
                        </tr>
                    </thead>

                            case 31:
                                return "外卖";
                                break;
                        }
                    }
                },
                {
                    "data": 'orderMoney',
                    "render": function (data, type, full) {
                      return data*0.01;
                    }
                }
            ],
            "columnDefs": [
                {
                    "targets": [8],
                    "data": "firmId",
                    "render": function(data, type, full) {
                        return "<a href='<%=basePath%>Admin/lookupFirmDetail?firmId=" + data + "'>查看详情</a>";
                    }
                }
            ]
        });
        table.on( 'order.dt search.dt', function () {
            table.column(0, {search:'applied', order:'applied'}).nodes().each( function (cell, i) {
                cell.innerHTML = i+1;
            } );
        } ).draw();
    });

function format(date, fmt) {

var o = {

"M+": date.getMonth() + 1,                 //月份

"d+": date.getDate(),                    //日

"h+": date.getHours(),                   //小时

"m+": date.getMinutes(),                 //分

"s+": date.getSeconds()                 //秒

};

if (/(y+)/.test(fmt))

fmt = fmt.replace(RegExp.$1, (date.getFullYear() + "").substr(4 - RegExp.$1.length));

for (var k in o)

if (new RegExp("(" + k + ")").test(fmt))

fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));

return fmt;

}

</script>　

2、根据Datatable需要的Json数据格式，提供DatatableVO实体类。

 public class DataTableResultVO<T>{
     private int draw;//请求的次数
     private int recordsTotal;//返回的记录总数
     private int recordsFiltered; //过滤后的数据总数
     private List<T> data; // 显示到页面的数据

     public DataTableResultVO() {}

     public int getDraw() {
         return draw;
     }

     public void setDraw(int draw) {
         this.draw = draw;
     }

     public int getRecordsTotal() {
         return recordsTotal;
     }

     public void setRecordsTotal(int recordsTotal) {
         this.recordsTotal = recordsTotal;
     }

     public int getRecordsFiltered() {
         return recordsFiltered;
     }

     public void setRecordsFiltered(int recordsFiltered) {
         this.recordsFiltered = recordsFiltered;
     }

     public List<T> getData() {
         return data;
     }

     public void setData(List<T> data) {
         this.data = data;
     }

     @Override
     public String toString() {
         return "DataTableResultVO{" +
                 "draw=" + draw +
                 ", recordsTotal=" + recordsTotal +
                 ", recordsFiltered=" + recordsFiltered +
                 ", data=" + data +
                 '}';
     }
 }

3、springmvc构造Datable需要的json数据格式

    @RequestMapping(value = "/Admin/loadFirms.do",method = {RequestMethod.POST})
    @ResponseBody
    public String loadFirms(HttpServletRequest request, HttpServletResponse response){
        try {
            List<Firm> firms=firmService.loadFirmsToAdmin();
            DataTableResultVO<Firm> result=new DataTableResultVO<>();
            result.setData(firms);//data参数。
            result.setRecordsTotal(firms.size());//数据的条数
            result.setRecordsFiltered(firms.size());//过滤后数据的条数
            return JSONObject.fromObject(result).toString();
        }catch (Exception e){
            e.printStackTrace();
        }
        return null;
    }

4、利用mybatis实现Service层与Dao层

//FirmServiceImpl、获取数据列表
public List<Firm> loadFirmsToAdmin()throws Exception{
        return firmDao.selectFirmsByTableParams();
    }

//FirmDao接口

public Firm selectFirmDetailToAdmin(String firmId);

//FirmDaoxml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD iBatis Mapper 3.0 //EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.daiba.firm.dao.FirmDao">

<!---管理员页面通过分页获取订单列表-->

<select id="selectFirmsByTableParams" resultMap="firmResultMap">

SELECT f.firm_id,o.accept_add_code,f.use_id,u.name,o.receiver,f.order_state,o.sta_id,f.give_time,f.order_money

FROM firm f,orders o,user u

WHERE f.ord_id = o.order_id

AND f.use_id=u.user_id

ORDER BY f.order_state ASC,f.give_time DESC

</select>

<!--mybatis常识:使用resultMap的时候记得要在mybatis.xml里面添加实体依赖注入typealis-->

<resultMap id="firmResultMap" type="Firm">

<id property="firmId" column="firm_id" jdbcType="VARCHAR"/>

<result property="briId" column="bri_id" jdbcType="INTEGER"/>

<result property="address" column="address" jdbcType="VARCHAR"/>

<result property="askTime" column="ask_time"/>

<result property="remark" column="remark" jdbcType="VARCHAR"/>

<result property="orderMoney" column="order_money" jdbcType="INTEGER"/>

<result property="giveTime" column="give_time"/>

<result property="acceptTime" column="accept_time"/>

<result property="finishTime" column="finish_time"/>

<result property="cancleTime" column="cancle_time"/>

<result property="orderState" column="order_state" jdbcType="INTEGER"/>

<result property="isApplyCancel" column="is_apply_cancel" jdbcType="INTEGER"/>

<association property="user" javaType="User">

<id property="userId" column="use_id" jdbcType="INTEGER"/>

<result property="name" column="name" jdbcType="VARCHAR"/>

<result property="portrait" column="portrait" jdbcType="VARCHAR"/>

<result property="phoneNum" column="phone_num" jdbcType="VARCHAR"/>

<result property="password" column="password" jdbcType="VARCHAR"/>

<result property="registerTime" column="register_time"/>

<result property="role" column="role" jdbcType="VARCHAR"/>

<result property="recetlyLoginTime" column="recetly_login_time"/>

<result property="orderNum" column="order_num" jdbcType="INTEGER"/>

<result property="spending" column="spending" jdbcType="DOUBLE"/>

<result property="sex" column="sex" jdbcType="INTEGER"/>

<result property="openId" column="open_id" jdbcType="VARCHAR"/>

</association>

<association property="order" javaType="Order">

<id property="orderId" column="ord_id" jdbcType="VARCHAR"/>

<result property="staId" column="sta_id" jdbcType="INTEGER"/>

<result property="acceptAddCode" column="accept_add_code" jdbcType="VARCHAR"/>

<result property="company" column="company" jdbcType="VARCHAR"/>

<result property="receiver" column="receiver" jdbcType="VARCHAR"/>

<result property="tokenNum" column="token_num" jdbcType="VARCHAR"/>

<result property="reservedPhone" column="reserved_phone" jdbcType="VARCHAR"/>

</association>

</resultMap>

</mapper>

三、后台分页

原理跟前台类似，只是数据分页、排序、查询在后台完成。

1、ajax请求重要参数(start、length、search[value])

　　start: 其实记录位置

　　length: 页面显示数量

　　order[0][column]: 因为是二维的表格，因此只有一维需要排序，所以 order 的下标未0. 该属性表示第几列需要排序。

　　order[0][dir]: 排序方式 ASC | DESC

　　search[value]: search 输入框中的值

2、Springmvc获取参数

 　  int pageSize = 10;
 　  int startRecord = 0;
     //分页的数据条数
     String size = request.getParameter("length");
     if (!"".equals(size) && size != null) {
         pageSize = Integer.parseInt(size);
     }
     //分页的当前位置
     String currentRecord = request.getParameter("start");
     if (!"".equals(currentRecord) && currentRecord != null) {
         startRecord = Integer.parseInt(currentRecord);
     }
     //用于排序
     String sortOrder = request.getParameter("order[0][column]");
     String sortDir = request.getParameter("order[0][dir]");
     System.out.println("sortOrder: " + sortOrder);
     System.out.println("sortDir: " + sortDir);

     // 用于搜索
     String searchValue = request.getParameter("search[value]");     

3、核心思想:组装sql，例如select * from firm where  1=1 order by sortOrder sortDir limit start，length。

4、dao层实现，利用servlet+jdbc对后台分页进行详细说明。
