基于SpringMVC+Bootstrap+DataTables实现表格服务端分页、模糊查询

前言

基于SpringMVC+Bootstrap+DataTables实现数据表格服务端分页、模糊查询（非DataTables Search），页面异步刷新。

说明：sp:message标签是使用了SpringMVC国际化

效果

DataTable表格

关键字查询

自定义关键字查询，非DataTable Search

代码

HTML代码

查询条件代码

<!-- 查询、添加、批量删除、导出、刷新 -->
<div class="row-fluid">
<div class="pull-right">
<div class="btn-group">
<button type="button" class="btn btn-primary btn-sm" id="btn-add">
<i class="fa fa-plus"></i> <sp:message code="sys.add"/>
</button>
<button type="button" class="btn btn-primary btn-sm" id="btn-delAll">
<i class="fa fa-remove"></i> <sp:message code="sys.delAll"/>
</button>
<button type="button" class="btn btn-primary btn-sm" id="btn-export">
<i class="fa fa-sign-in"></i> <sp:message code="sys.export"/>
</button>
<button type="button" class="btn btn-primary btn-sm" id="btn-re">
<i class="fa fa-refresh"></i> <sp:message code="sys.refresh"/>
</button>
</div>
</div>
<div class="row">
<form id="queryForm" action="<%=path%>/goodsType/list" method="post">
<div class="col-xs-2">
<input type="text" id="keyword" name="keyword" class="form-control input-sm"
placeholder="<sp:message code="sys.keyword"/>">
</div>
<button type="button" class="btn btn-primary btn-sm" id="btn-query">
<i class="fa fa-search"></i> <sp:message code="sys.query"/>
</button>
</form>
</div>
</div>

数据table代码

<table id="dataTable" class="table table-striped table-bordered table-hover table-condensed" align="center">
<thead>
<tr class="info">
<td><input type="checkbox" id="checkAll"></td>
<th><sp:message code="sys.no"/></th>
<th><sp:message code="goods.type.name.cn"/></th>
<th><sp:message code="goods.type.name.en"/></th>
<th><sp:message code="sys.create.time"/></th>
<th><sp:message code="sys.update.time"/></th>
<th><sp:message code="sys.oper"/></th>
</tr>
</thead>
</table>

JS代码

DataTables初始化、服务端数据请求、查询条件封装

<!-- page script -->
<script>
$(function () {
//添加、修改异步提交地址
var url = "";

var tables = $("#dataTable").dataTable({
serverSide: true,//分页，取数据等等的都放到服务端去

pageLength: 10,  //首次加载的数据条数
ordering: false, //排序操作在服务端进行，所以可以关了。
pagingType: "full_numbers",
autoWidth: false,
stateSave: true,//保持翻页状态，和comTable.fnDraw(false);结合使用
searching: false,//禁用datatables搜索

var formData = $("#queryForm").serializeArray();//把form里面的数据序列化成数组
formData.forEach(function (e) {

Java代码

Controller处理方法，负责查询页面需要表格数据，格式化Json后返回。

@RequestMapping(value="/goodsType/getData", produces = "text/json;charset=UTF-8")
@ResponseBody
public String getData(HttpServletRequest request, QueryCondition query) {
DatatablesView<GoodsType> dataTable = goodsTypeService.getGoodsTypeByCondition(query);
dataTable.setDraw(query.getDraw());
String data = JSON.toJSONString(dataTable);
return data;
}

返回Json数据格式

{
"data": [{
"createTime": "2016-10-27 09:42:28.0",
"typeId": 96824775296417986,
"typeIdStr": "96824775296417986",
"typeNameCn": "食品",
"typeNameEn": "Foods",
"updateTime": "2016-10-28 13:00:24.0"
},
{
"createTime": "2016-10-27 09:42:27.0",
"typeId": 96824775296417979,
"typeIdStr": "96824775296417979",
"typeNameCn": "汽车",
"typeNameEn": "Cars123",
"updateTime": "2016-10-27 09:51:24.0"
}],
"draw": 1,
"recordsFiltered": 17,
"recordsTotal": 17
}

DatatablesView，根据DataTables需要格式定义

public class DatatablesView<T> {

private List<T> data; //data 与datatales 加载的“dataSrc"对应

private int recordsTotal;

private int recordsFiltered;

private int draw;

public DatatablesView() {

}

public int getDraw() {
return draw;
}

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

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

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

public int getRecordsTotal() {
return recordsTotal;
}

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

public int getRecordsFiltered() {
return recordsFiltered;
}

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

Service业务处理类，主要根据查询条件统计记录数量，查询当前页数据列表

public DatatablesView<GoodsType> getGoodsTypeByCondition(QueryCondition query) {
DatatablesView<GoodsType> dataView = new DatatablesView<GoodsType>();

//构建查询条件
WherePrams where = goodsTypeDao.structureConditon(query);

Long count = goodsTypeDao.count(where);
List<GoodsType> list = goodsTypeDao.list(where);

dataView.setRecordsTotal(count.intValue());
dataView.setData(list);

return dataView;
}

Dao层就是基本的数据库查询操作，这里省略…

结尾

查询条件这里只使用了关键字模糊查询，根据业务需要，可以动态加入其他查询条件，后台需要做相应处理。
