EasyPoi 导出大量数据

1：引入jia包：在pom.xml中引入一下jia包：

		
            cn.afterturn
            easypoi-base
            4.1.0
        
        
            cn.afterturn
            easypoi-web
            4.1.0
        
        
            cn.afterturn
            easypoi-annotation
            4.1.0
        

2：代码如下：
代码（一）：Controller请求

/**    
     * 导出数据
     *
     * @param workOrderQuery
     * @param modelMap
     * @param response
     * @param request
     */
    @RequestMapping(value = "/exportWorkOrder", method = RequestMethod.POST)
    public void exportWorkOrder(WorkOrderQuery workOrderQuery, ModelMap modelMap, HttpServletResponse response, HttpServletRequest request) {
        workOrderService.exportWorkOrder(workOrderQuery , modelMap, response, request);
    }

代码二：接口

    void exportWorkOrder(WorkOrderQuery workOrderQuery , ModelMap modelMap, HttpServletResponse response, HttpServletRequest request);

代码三：实现类：导出，只要引入上面的jia包。所有的功能都在里面，直接使用即可。

@Override
    public void exportWorkOrder(WorkOrderQuery workOrderQuery, ModelMap modelMap, HttpServletResponse response, HttpServletRequest request) {
        List workOrderExcelDTOS = myWorkOrderMapper.getWorkOrderExcelList(workOrderQuery);//查询数据 List集合
        Assert.isTrue(workOrderExcelDTOS.size() == 0, ResultCodeEnum.NO_DATA_CAN_BE_EXPORTED);

        ExportParams exportParams = new ExportParams();
        exportParams.setType(ExcelType.XSSF);
        //exportParams.setAddIndex(true);

        modelMap.put(NormalExcelConstants.DATA_LIST, workOrderExcelDTOS);//查询出来的List数据
        modelMap.put(NormalExcelConstants.CLASS, WorkOrderExcelDTO.class);//实例化
        modelMap.put(NormalExcelConstants.PARAMS, exportParams);//传递的参数
        modelMap.put(NormalExcelConstants.FILE_NAME, "work-order");//导出表的名称
        PoiBaseView.render(modelMap, request, response, NormalExcelConstants.EASYPOI_EXCEL_VIEW);//调用封装好的的方法：直接导出即可，这个是调用的普通的导出，还可以使用导出大量的数据，到时候可以点进去看看源码。

    }

导出的字段实体：

public class WorkOrderExcelDTO implements Serializable {

    private static final long serialVersionUID = 1L;

    @Excel(name = "工单编号", width = 15)
    private String workOrderNum;

    @Excel(name = "订单编号", width = 15)
    private String orderNum;

    @Excel(name = "订单发货时间", width = 25, format = "yyyy-MM-dd HH:mm:ss")
    private Date successTime;

    @Excel(name = "创建时间", width = 25, format = "yyyy-MM-dd HH:mm:ss")
    private Date createDate;

    @Excel(name = "实际完结时间", width = 25, format = "yyyy-MM-dd HH:mm:ss")
    private Date actualCompletionDate;

    @Excel(name = "工单类型", width = 15, replace = {"异常-超时未处理_0", "咨询-发货无物流_1", "咨询-物流停滞_2", "咨询-物流流转_3", "咨询-错发/漏发_4",
            "咨询-补货款差价_5", "咨询-订单状态异常_6", "咨询-配件缺失_7", "咨询-退货少件_8", "咨询-商品下架_9", "咨询-协商退货_10", "赔付-退运费_11",
            "赔付-退货款差价_12", "赔付-商品质量问题_13", "赔付-破损_14", "赔付-补偿安慰_15", "退货退款-无理由退货退款_16", "仲裁-用户发起仲裁_17",
            "投诉-公司投诉_18", "投诉-媒体/工商投诉_19", "投诉-服务态度_20", "投诉-服务效率_21", "退货退款-商品质量问题_22", "咨询-退货异常_23",
            "异常-拦截异常_24", "技术-推送云仓销售出库单失败_25", "技术-推送云仓退货入库单失败_26", "异常-回寄异常_27", "异常-退货异常_28", "异常-超时未确认收货_29"
    })
    private Integer workOrderType;

    @Excel(name = "工单状态", width = 15, replace = {"待认领_0", "跟进中_1", "已完结_2", "待跟进_3"})
    private Integer status;

    @Excel(name = "所属技能组", width = 15)
    private String groupName;

    @Excel(name = "负责人", width = 15)
    private String responsiblePerson;

    @Excel(name = "创建人", width = 15)
    private String createName;

    @Excel(name = "供应商家", width = 15)
    private String otherName;

    @Excel(name = "用户手机号", width = 15)
    private String mobile;

    @Excel(name = "收货人姓名", width = 15)
    private String name;

    @Excel(name = "收货人手机号", width = 15)
    private String phone;

    @Excel(name = "收货人地址", width = 15)
    private String address;

}
