介绍

easypoi功能如同名字easy,主打的功能就是容易,让一个没接触过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:

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 */@Datapublic 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;}

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);    }
