easypoi功能如同名字easy,主打的功能就是容易,讓一個沒見接觸過poi的人員
就可以友善的寫出Excel導出,Excel模闆導出,Excel導入,Word模闆導出,通過簡單的注解和模闆

建立導出excel模闆的實體類，也可以按照模闆導出具體看官網文檔
導出excel模闆的實體類代碼如下：
package com.meeno.framework.office.excel.easypoi.model;
import cn.afterturn.easypoi.excel.annotation.Excel;
import lombok.Data;
import java.io.Serializable;
/**
* @description: 簽到記錄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;
/**
* 人員名稱
*/
@Excel(name = "人員名稱",orderNum = "1")
private String employeeName;
/**
* 座位号
*/
@Excel(name = "座位号",orderNum = "2")
private Integer seatNum;
/**
* 簽到狀态
*/
@Excel(name = "簽到狀态",orderNum = "3")
private String signStatusStr;
}
使用easypoi導出excel
controller層調用代碼
/**
*@Description 導出登入記錄表
*@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);
//會議id
Long meetingId = jsonObject.getLong("meetingId");
List<SignRecordExcelModel> signRecordExcelModels = this.signRecordService.exportSignRecord(meetingId);
Meeting meeting = this.meetingService.getMeetingDetail(meetingId);
//第一參數:導出的模闆類集合
//第二參數:excel中裡面内容合并單元格的title
//第三參數:seeetName名稱
//第四參數:導出模闆實體類的class
//第五參數:導出檔案檔案名
//第六參數:HttpServletResponse
ExcelUtiles.exportExcel(signRecordExcelModels,"","簽到表",SignRecordExcelModel.class,meeting.getName()+"簽到表.xlsx",response);
}
導出效果
