}

创建导出excel模板的实体类，也可以按照模板导出具体看官网文档

导出excel模板的实体类代码如下：

package com.meeno.framework.office.excel.easypoi.model;import cn.afterturn.easypoi.excel.annotation.Excel;
import lombok.Data;import java.io.Serializable;/*** @description: 签到记录ExecelModel* @author: Wzq* @create: 2020-01-07 11:34*/
@Data
public class SignRecordExcelModel implements Serializable {/*** 序号*/@Excel(name = "序号",orderNum = "0")private Integer number;/*** 人员名称*/@Excel(name = "人员名称",orderNum = "1")private String employeeName;/*** 座位号*/@Excel(name = "座位号",orderNum = "2")private Integer seatNum;/*** 签到状态*/@Excel(name = "签到状态",orderNum = "3")private String signStatusStr;}

使用easypoi导出excel

controller层调用代码

/***@Description 导出登录记录表*@Param [session, request, response, data]*@Return void*@Author Wzq*@Date 2020/1/7*@Time 11:06*/@RequestMapping(value = "exportSignRecord.action")public void  exportSignRecord(final HttpSession session,final HttpServletRequest request,final HttpServletResponse response,@RequestParam(value = "Data",required = false) String data){JSONObject jsonObject = JSONObject.parseObject(data);//会议idLong meetingId = jsonObject.getLong("meetingId");List<SignRecordExcelModel> signRecordExcelModels = this.signRecordService.exportSignRecord(meetingId);Meeting meeting = this.meetingService.getMeetingDetail(meetingId);//第一参数:导出的模板类集合//第二参数:excel中里面内容合并单元格的title//第三参数:seeetName名称//第四参数:导出模板实体类的class//第五参数:导出文件文件名//第六参数:HttpServletResponseExcelUtiles.exportExcel(signRecordExcelModels,"","签到表",SignRecordExcelModel.class,meeting.getName()+"签到表.xlsx",response);}
