DataTables官网：

[http://www.datatables.club/][http_www.datatables.club]

在你的项目中使用 DataTables，只需要引入三个文件即可，jQuery库，一个DT的核心js文件和一个DT的css文件。

这里使用的Thymeleaf模板，juqery是在foot中引用下面展示content部分。

## 实现 ##

### 编写模板并引入js ###

首先在模板文件html中编写要显示的字段信息

<!DOCTYPE html>
    <html xmlns:th="http://www.thymeleaf.org" xmlns:shiro="http://www.pollix.at/thymeleaf/shiro"
         th:replace="layout/layout(title='收货单数据',cssPaths='/public/css/plugins/dataTables/datatables.min.css,/public/css/plugins/daterangepicker/daterangepicker-bs3.css,/public/css/plugins/jsTree/style.min.css',jsPaths='/public/js/plugins/dataTables/datatables.min.js,/public/js/plugins/dataTables/dataTables.bootstrap4.min.js,/public/js/plugins/fullcalendar/moment.min.js,/public/js/plugins/jsTree/jstree.min.js,/public/js/plugins/sweetalert/sweetalert2.all.min.js,/public/js/plugins/ladda/spin.min.js,/public/js/plugins/ladda/ladda.min.js,/public/js/plugins/ladda/ladda.jquery.min.js,/public/js/plugins/select2/select2.full.min.js,/public/js/plugins/dropzone/dropzone.js,/public/js/plugins/switchery/switchery.js,/public/js/plugins/daterangepicker/daterangepicker.js,/public/js/plugins/datapicker/bootstrap-datepicker.js,/public/js/plugins/validate/jquery.validate.min.js,/public/js/plugins/validate/validate_zh.js,/modular/utils.js,/modular/receiveOrder/wmsReceiveOrder.js')">
    <div th:fragment="content">
        <div class="ibox float-e-margins">
           
            <div class="ibox-content">
                <div class="table-responsive">
                    <P>
                        <shiro:hasPermission name="roleAdd">　　
    
                        </shiro:hasPermission>
                        <button id="detailBtn" class="btn btn-info " type="button"><i class="fa fa-trash-o"></i> 查看</button>
                        <button id="submitBtn" class="btn btn-info " type="button"><i class="fa fa-trash-o"></i> 提交</button>
                        <button id="importBtn" class="btn btn-info " type="button"><i class="fa fa-trash-o"></i> 导入</button>
                        <button id="printBtn" class="btn btn-info " type="button"><i class="fa fa-trash-o"></i> 打印</button>
                        <button id="dowloadBtn" class="btn btn-info " type="button"><i class="fa fa-trash-o"></i> 模板下载</button>
                        <button id="InOrderBtn" class="btn btn-info " type="button"><i class="fa fa-trash-o"></i> 生成入库单数据</button>
                        <button id="refreshBt" class="btn btn-info " type="button"><i class="fa fa-refresh"></i> 刷新</button>
                    </P>
                    <p>
    
                    </p>
                    <table id="wmsReceiveOrder_table_id" class="table table-striped table-bordered hover" style="width:100%">
                        <thead>
                        <tr>
                            <th>序号</th>
                            <th>收货单号</th>
                            <th>收货日期</th>
                            <th>收货人</th>
                            <th>供应商编号</th>
                            <th>供应商名称</th>
                            <th>总托数</th>
                            <th>总件数</th>
                            <th>送货单号</th>
                            <th>创建人</th>
                            <th>创建日期</th>
                            <th>状态</th>
                        </tr>
                        </thead>
                        <tbody>
                        </tbody>
                    </table>
                </div>
            </div>
        </div>
       
       
    </div>
    
    </html>

通过上面的引入js文件将js文件引入

其中wmsReceiveOrder.js是自己编写的js文件。

### 初始化DataTables ###

在wmsReceiveOrder.js中

/ DataTable初始化
      var t = dataTableInit();
      //---------------------------点击事件区域-------------------------
      //DataTable 行点击事件，用来设置样式点击事件
      $('#wmsReceiveOrder_table_id tbody').on('click', 'tr', function () {
        if (!$(this).hasClass('selected') ) {
          t.$('tr.selected').removeClass('selected');
          $(this).addClass('selected');
        }
      } );
      //DataTable重新渲染时序号一栏重新进行编号点击事件
      t.on( 'draw.dt', function () {
        var PageInfo = $('#wmsReceiveOrder_table_id').DataTable().page.info();
        t.column(0, { page: 'current' }).nodes().each( function (cell, i) {
          cell.innerHTML = i + 1 + PageInfo.start;
        } );
      } );
      //刷新按钮事件
      $("#refreshBt").click(function () {
        // 刷新表格数据，分页信息不会重置
        t.ajax.reload( null, false );
      });
     
    
    
        //模板下载按钮点击事件
        $("#dowloadBtn").click(function () {
            templateDowload()
        });
      //导入按钮点击事件
        $("#importBtn").click(function () {
            importExcel();

                })
            }else
                submitInOrder(data.id);
    
        });
       
        //提交按钮点击事件
        $("#submitBtn").click(function () {
            var data = t.rows(['.selected']).data()[0];
            if(undefined===data){
                swal({
                    type: 'warning',

                    confirmButtonColor: "#1ab394",
                })
            }
            else if(data.status.trim()==="2") {
                debugger
                swal({
                    type: 'warning',
                    title: '提示:',
                    text: '该订单状态已提交！',
                    confirmButtonColor: "#1ab394",
                })
            }else{
                submitPrint(data.id);
            }
    
        });

                  } },

                          value.search.value = $(this).val();

                      }
                  });
              })
            $.ajax({
              type: 'POST',
              url: "/wmsReceiveOrder/doPageForReceiveOrderTable",
              cache: false,  //禁用缓存
              data: JSON.stringify(data),  //传入组装的参数
              contentType: "application/json",
              dataType: "json",
              success: function (result) {
                debugger
                callback(result);
              }
            })
          }
        })
      }

在js中先进行dataTables初始化，然后国际化配置，然后进行数据填充，最后进行ajax请求数据。

### 后台返回数据 ###

在后台Controller中

@Description("获取数据接口")
        @ResponseBody
        @RequestMapping(value = "/doPageForReceiveOrderTable")
        public DataTablesResultJsonVO doPageForMaterielTable(@RequestBody DataTablesJsonVO vo) {
            DataTablesResultJsonVO dataTablesResultJsonVO = new DataTablesResultJsonVO();
            try {
                String keyHump = vo.getColumns().get(vo.getOrder().get(0).getColumn().intValue()).getData();
                String keyLine = StringUtil.humpToLine(keyHump);
                String sortStr = vo.getOrder().get(0).getDir();
                Page<WmsReceiveOrderVO> pageEntity = new Page<>(vo.getStart()/vo.getLength()+1, vo.getLength());
                IPage<WmsReceiveOrderVO> page = receiveOrderService.pageTray(pageEntity, vo);
                dataTablesResultJsonVO.setData(page.getRecords());
                dataTablesResultJsonVO.setDraw(vo.getDraw());
                dataTablesResultJsonVO.setError("error");
                dataTablesResultJsonVO.setRecordsFiltered(page.getTotal());
                dataTablesResultJsonVO.setRecordsTotal(page.getSize());
                Log.getInst(this).debug("doPageForRoleTable test:" + vo.getColumns().get(0).getSearch());
                return dataTablesResultJsonVO;
            } catch (Exception ex) {
                Log.getInst().debug("获取数据接口:",ex);
                dataTablesResultJsonVO.setData(new ArrayList<WmsReceiveOrderVO>());
                dataTablesResultJsonVO.setDraw(vo.getDraw());
                dataTablesResultJsonVO.setError("error");
                dataTablesResultJsonVO.setRecordsFiltered(0L);
                dataTablesResultJsonVO.setRecordsTotal(0L);
                Log.getInst(this).debug("doPageForRoleTable test:" + vo.getColumns().get(0).getSearch());
                return dataTablesResultJsonVO;
            }
    
        }

使用封装的DataTablesJsonVO请求对象

import lombok.Data;
    
    import java.io.Serializable;
    import java.util.List;
    @Data
    public class DataTablesJsonVO implements Serializable{
        private Long draw;
        private List<DataTablesColumnsJsonVO> columns;
        private List<DataTablesOrderJsobVO> order;
        private Long start;
        private Long length;
        private DataTablesOrderJsobVO search;
    }

其中DataTablesColumnsJsonVO

import lombok.Data;
    
    import java.io.Serializable;
    
    @Data
    public class DataTablesColumnsJsonVO implements Serializable {
        private String data;
        private String name;
        private boolean searchable;
        private boolean orderable;
        private DataTablesSearchJsnVO search;
    }

DataTablesOrderJsobVO

import lombok.Data;
    
    import java.io.Serializable;
    
    @Data
    public class DataTablesOrderJsobVO implements Serializable {
        private Long column;
        private String dir;
    }

使用了封装的响应DataTablesResultJsonVO

import lombok.Data;
    
    import java.io.Serializable;
    import java.util.List;
    
    @Data
    public class DataTablesResultJsonVO<T> implements Serializable {
        private Long draw;
        private Long recordsTotal;
        private Long recordsFiltered;
        private List<T> data;
        private String error;
    }

要显示的数据通过receiveOrderService.pageTray(pageEntity, vo);  
查询获取。
