超级简单POI多sheet导出Excel实战，与现有系统无缝对接 ......
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：
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', `merger_name` varchar(50) not null default '' comment '组合名', `pinyin` varchar(30) not null default '' comment '拼音', `lng` decimal(10,6) not null default '0.000000' comment '经度', `lat` decimal(10,6) not null default '0.000000' comment '纬度', primary key (`id`), unique key `idx` (`area_code`) using btree ) engine=myisam auto_increment=778093 default charset=utf8 comment='中国行政地区表';

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：
