介绍
easypoi功能如同名字easy,主打的功能就是容易,让一个没见接触过poi的人员
就可以方便的写出Excel导出,Excel模板导出,Excel导入,Word模板导出,通过简单的注解和模板
官网地址:http://easypoi.mydoc.io/
easypoi需要导入的包

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id
Long 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:HttpServletResponse
ExcelUtiles.exportExcel(signRecordExcelModels,"","签到表",SignRecordExcelModel.class,meeting.getName()+"签到表.xlsx",response);
}
导出效果
