超级简单POI多sheet导出Excel实战

本章节主要基于上一章节单sheet导出的基础上进行改造实现多sheet的导出,上一章节参考地址:https://www.cnblogs.com/sunny1009/p/11437005.html

1.数据准备

这里导出两个sheet为例进行讲解,第一个sheet导出学生基本信息,表结构和数据参考上一章节,第二个sheet导出区域基本信息,具体数据和脚本如下

CREATE TABLE `td_area` (
  `id` mediumint(7) unsigned NOT NULL AUTO_INCREMENT,
  `level` tinyint(1) unsigned NOT NULL COMMENT '层级',
  `parent_code` bigint(14) unsigned NOT NULL DEFAULT '0' COMMENT '父级行政代码',
  `area_code` bigint(14) unsigned NOT NULL DEFAULT '0' COMMENT '行政代码',
  `zip_code` mediumint(6) unsigned zerofill NOT NULL DEFAULT '000000' COMMENT '邮政编码',
  `city_code` char(6) NOT NULL DEFAULT '' COMMENT '区号',
  `name` varchar(50) NOT NULL DEFAULT '' COMMENT '名称',
  `short_name` varchar(50) NOT NULL DEFAULT '' COMMENT '简称',

  `lat` decimal(10,6) NOT NULL DEFAULT '0.000000' COMMENT '纬度',

2.创建区域信息查询接口

package com.sunny.spring.boot.poi.service;

import com.sunny.spring.boot.poi.pojo.TdArea;

import java.util.List;

/**
 * @ClassName: IAreaService
 * @Description:
 * @Author: sunt
 * @Date: 2019/9/2 15:49
 * @Version 1.0
 **/
public interface IAreaService {

    /**
     * 查询所有行政区域信息
     * @return
     */
    List<TdArea> queryAreaInfo();
}

3.实体Bean创建

package com.sunny.spring.boot.poi.pojo;

import cn.afterturn.easypoi.excel.annotation.Excel;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.experimental.Accessors;

import java.io.Serializable;
import java.math.BigDecimal;

/**
 * <p>
 * 中国行政地区表
 * </p>
 *
 * @author sunt
 * @since 2019-08-22
 */
@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
public class TdArea implements Serializable {

    private static final long serialVersionUID = 1L;

    /**
     * 层级
     */
    @Excel(name = "层级", width = 20, orderNum = "1")
    private int level;

    /**
     * 父级行政代码
     */
    @Excel(name = "父级行政代码", width = 20, orderNum = "1")
    private Long parentCode;

    /**
     * 行政代码
     */
    @Excel(name = "行政代码", width = 20, orderNum = "1")
    private Long areaCode;

    /**
     * 邮政编码
     */
    @Excel(name = "邮政编码", width = 20, orderNum = "1")
    private Integer zipCode;

    /**
     * 区号
     */
    @Excel(name = "区号", width = 20, orderNum = "1")
    private String cityCode;

    /**
     * 名称
     */
    @Excel(name = "名称", width = 20, orderNum = "1")
    private String name;

    /**
     * 简称
     */
    @Excel(name = "简称", width = 20, orderNum = "1")
    private String shortName;

    /**
     * 组合名
     */
    @Excel(name = "组合名", width = 20, orderNum = "1")
    private String mergerName;

    /**
     * 拼音
     */
    @Excel(name = "拼音", width = 20, orderNum = "1")
    private String pinyin;

    /**
     * 经度
     */
    @Excel(name = "经度", width = 20, orderNum = "1")
    private BigDecimal lng;

    /**
     * 纬度
     */
    @Excel(name = "纬度", width = 20, orderNum = "1")
    private BigDecimal lat;


}

4.导出Controller

具体代码都有详细注释

 /**
     * 多个sheet的导出
     *  第一个sheet展示学生基本信息
     *  第二个sheet展示区域信息基本信息
     * 步骤:
     *  构建一个List<Map<String, Object>> list  多个Map key title 对应表格Title key entity 对应表格对应实体 key data
     *  具体操作看代码
     * @param response
     */
    @RequestMapping("/exportMoreSheet")
    public void exportMoreSheet(HttpServletResponse response) {
        //1.分别构建学生与区域信息导出参数
        ExportParams stuParam = new ExportParams();
        ExportParams areaParam = new ExportParams();

        stuParam.setSheetName("学生基本信息");
        stuParam.setHeight((short) 8);
        stuParam.setStyle(ExcelExportMyStylerImpl.class);

        areaParam.setSheetName("区域基本信息");
        areaParam.setHeight((short) 8);
        areaParam.setStyle(ExcelExportMyStylerImpl.class);

        //2.构建分别填充数据:data(数据)、title(标题)、entity(导出属性)
        Map<String, Object> exportStuMap = new HashMap<String, Object>();
        Map<String, Object> exportAreaMap = new HashMap<String, Object>();

        exportStuMap.put("data", studentService.queryAllStudent());
        exportStuMap.put("title", stuParam);
        exportStuMap.put("entity", StudentInfoBean.class);

        exportAreaMap.put("data", areaService.queryAreaInfo());
        exportAreaMap.put("title", areaParam);
        exportAreaMap.put("entity", TdArea.class);

        //3.组装参数
        List<Map<String, Object>> sheetsList = new ArrayList<Map<String, Object>>();
        sheetsList.add(exportStuMap);
        sheetsList.add(exportAreaMap);

        try {
            //4.调用导出接口
            Workbook workbook = ExcelExportUtil.exportExcel(sheetsList, ExcelType.HSSF);
            String fileName = "多sheet导出"+new SimpleDateFormat("yyyyMMdd").format(new Date());
            fileName = URLEncoder.encode(fileName, "UTF8");
            response.setContentType("application/vnd.ms-excel;chartset=utf-8");
            response.setHeader("Content-Disposition", "attachment;filename="+fileName + ".xls");
            ServletOutputStream out=response.getOutputStream();
            workbook.write(out);
            out.flush();
            out.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

5.测试

浏览器访问导出Controller:http://127.0.0.1:8080/export/exportMoreSheet

 

第二个sheet的值:
