Java解析、生成Excel比较有名的框架有Apache poi、jxl。但他们都存在一个严重的问题就是非常的耗内存，poi有一套SAX模式的API可以一定程度的解决一些内存溢出的问题，但POI还是有一些缺陷，比如07版Excel解压缩以及解压后存储都是在内存中完成的，内存消耗依然很大。easyexcel重写了poi对07版Excel的解析，能够原本一个3M的excel用POI sax依然需要100M左右内存降低到KB级别，并且再大的excel不会出现内存溢出，03版依赖POI的sax模式。在上层做了模型转换的封装，让使用者更加简单方便。
我建议大家使用1.1.2-beta4版本，也就是官方给的最新版，maven仓库查到的最新版比这个版本略低，最显著的区别就是excel中数字的输出，最新版本到处excel会将数字专为数字格式，而maven库给出的最新版则会输出成文本格式。其他变化需要各位自己去发现。

1.1.2-beta4
使用方法
1.表头带注解方法
这种方法首先需要一个继承BaseRowModel的模型，在Hap框架dto的角色就相当于这个模型，示例如下
package ect.report.dto;
import com.alibaba.excel.annotation.ExcelProperty;
import com.alibaba.excel.metadata.BaseRowModel;
import java.math.BigDecimal;
import java.util.Date;
/**
* @ClassName: TraBilDetail
* @Description: TODO
* @Date: 2019-03-29 09:52
* @Version 1.0
*/
public class TraBilDetail extends BaseRowModel {
//开票申请号
@ExcelProperty(value = {"开票申请号"}, index = 0)
private String applyNum;
//批次号
@ExcelProperty(value = {"批次号"}, index = 1)
private String batchNum;
//制单部门
@ExcelProperty(value = {"制单部门"}, index = 2)
private String name;
//客户名称
@ExcelProperty(value = {"客户名称"}, index = 3)
private String custName;
//业务类型
@ExcelProperty(value = {"业务类型"}, index = 4)
private String busiType;
//批次开票金额
@ExcelProperty(value = {"批次开票金额"}, index = 5)
private BigDecimal sumPrice;
//批次开票重量
@ExcelProperty(value = {"批次开票重量"}, index = 6)
private BigDecimal invoWeight;
//批次财务入总金额
@ExcelProperty(value = {"批次财务入总金额"}, index = 7)
private BigDecimal findInAmoundSum;
//邮寄信息
@ExcelProperty(value = {"邮寄信息"}, index = 8)
private String mailAddress;
private String contactName;
private String telephone;
/*=========================== 查询字段================================*/
private Long comId;
private Date applyDateStart;
private Date applyDateEnd;
/*=====================================*/
get和set方法省略
/*=====================================*/
}
然后mapper.java,Service.java,～ServiceImpl.java都要去掉继承系统框架的base接口。mapper层写好查询出需要展示的数据，dto的注解中字段对应的显示。上述例子写的是单层头结构，如果想要写成双层或者多层，可以想一下示例一样添加。
package ect.report.dto;
import com.alibaba.excel.annotation.ExcelProperty;
import com.alibaba.excel.metadata.BaseRowModel;
import java.math.BigDecimal;
/**
* @ClassName: BatchSupply
* @Description: TODO
* @Date: 2019-04-02 09:00
* @Version 1.0
*/
public class BatchSupply extends BaseRowModel {
//公司名称
@ExcelProperty(value = {"在库货源","姓名"} ,index = 0)
private String comName;
//仓库名称
@ExcelProperty(value = {"在库货源","仓库名称"} ,index = 1)
private String subinvName;
//产地
@ExcelProperty(value = {"在库货源","产地"} ,index = 2)
private String terrName;
//等级
@ExcelProperty(value = {"在库货源","等级"} ,index = 3)
private String ctLevel;
//长度
@ExcelProperty(value = {"在库货源","长度"} ,index = 4)
private String length;
//长度均值
@ExcelProperty(value = {"在库货源","长度均值"} ,index = 5)
private String lengthMean;
//马值
@ExcelProperty(value = {"在库货源","马值"} ,index = 6)
private String micron;
//马值均值
@ExcelProperty(value = {"在库货源","马值均值"} ,index = 7)
private String micronMean;
//强力
@ExcelProperty(value = {"在库货源","强力"} ,index = 8)
private String strong;
//强力均值
@ExcelProperty(value = {"在库货源","强力均值"} ,index = 9)
private String strongMean;
//提单号
@ExcelProperty(value = {"在库货源","提单号"} ,index = 10)
private String blNum;
//入库单号
@ExcelProperty(value = {"在库货源","入库单号"} ,index = 11)
private String entryNum;
//箱号
@ExcelProperty(value = {"在库货源","箱号"} ,index = 12)
private String batchNum;
//入库件数
@ExcelProperty(value = {"在库货源","入库件数"} ,index = 13)
private BigDecimal batchQty;
//销售合同号
@ExcelProperty(value = {"在库货源","销售合同号"} ,index = 14)
private String conNum;
//出库单号
@ExcelProperty(value = {"在库货源","出库单号"} ,index = 15)
private String outNum;
//出库件数
@ExcelProperty(value = {"在库货源","出库件数"} ,index = 16)
private BigDecimal outBatchQty;
//在库箱数
@ExcelProperty(value = {"在库货源","在库箱数"} ,index = 17)
private String outStatus;
//在库件数
@ExcelProperty(value = {"在库货源","在库件数"} ,index = 18)
private BigDecimal wareQty;
//采购合同单价
@ExcelProperty(value = {"在库货源","采购合同单价"} ,index = 19)
private BigDecimal conPrice;
//财务入库成本
@ExcelProperty(value = {"在库货源","财务入库成本"} ,index = 20)
private BigDecimal finaPrice;
//初始财务入库成本(USD)
@ExcelProperty(value = {"在库货源","财务入库成本"} ,index = 21)
private BigDecimal firstUsdPrice;
//初始财务入库成本(CNY)
@ExcelProperty(value = {"在库货源","初始财务入库成本"} ,index = 22)
private BigDecimal firstRmbPrice;
private String lengthMax;
private String lengthMin;
private String micronMax;
private String micronMin;
private String strongMax;
private String strongMin;
private String terrCode;
private String comCode;
private String subinvId;
private String isBatchFlag;
private Long specId;
/*=====================================*/

/*=====================================*/
}
然后在Service层组装业务逻辑并且输出excel文档。
package ect.report.service.impl;
import com.alibaba.excel.ExcelWriter;
import com.alibaba.excel.metadata.Sheet;
import com.alibaba.excel.support.ExcelTypeEnum;
import ect.inv.util.StringUtils;
import ect.report.dto.TraBilDetail;
import ect.report.mapper.TraBilDetailMapper;
import ect.report.utils.EasyEacelUtils;
import jodd.util.StringUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import ect.report.service.ITraBilDetailService;
import org.springframework.transaction.annotation.Transactional;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;
/**
* @ClassName: TraBilDetailServiceImpl
* @Description: TODO
* @Date: 2019-03-29 09:53
* @Version 1.0
*/
@Service
@Transactional(rollbackFor = Exception.class)
public class TraBilDetailServiceImpl implements ITraBilDetailService{
@Autowired
private TraBilDetailMapper traBilDetailMapper;
@Override
public void export(HttpServletRequest request, TraBilDetail traBilDetail, HttpServletResponse httpServletResponse) throws IOException {
String fileName="内贸开票明细表";
//组装输出流
ServletOutputStream outputStream = EasyEacelUtils.createOutputStream(request, httpServletResponse, fileName);
try {
ExcelWriter writer = new ExcelWriter(outputStream, ExcelTypeEnum.XLSX);
Sheet sheet1 = new Sheet(1, 0, TraBilDetail.class);
//自适应宽度
sheet1.setAutoWidth(Boolean.TRUE);
//添加数据
writer.write(traBilDetailMapper.selectTraBilDetail(traBilDetail), sheet1);
writer.finish();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
outputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
这样一个非常简单的excel导出就完成了，这种方法适合于常规的excle导出。如果sql查询的数据还不能瞒住需求，需要Java中继续添加业务逻辑的话，可以继续组装成一个返回List的方法。示例如下

官方示例dome
OutputStream out = new FileOutputStream("/Users/jipengfei/2007.xlsx");
ExcelWriter writer = EasyExcelFactory.getWriterWithTemp(inputStream,out,ExcelTypeEnum.XLSX,true);
//写第一个sheet, sheet1 数据全是List 无模型映射关系
Sheet sheet1 = new Sheet(1, 3);
sheet1.setSheetName("第一个sheet");
//设置列宽 设置每列的宽度
Map columnWidth = new HashMap();
columnWidth.put(0,10000);columnWidth.put(1,40000);columnWidth.put(2,10000);columnWidth.put(3,10000);
sheet1.setColumnWidthMap(columnWidth);
sheet1.setHead(createTestListStringHead());
//or 设置自适应宽度
//sheet1.setAutoWidth(Boolean.TRUE);
writer.write1(createTestListObject(), sheet1);
//写第二个sheet sheet2 模型上打有表头的注解，合并单元格
Sheet sheet2 = new Sheet(2, 3, JavaModel1.class, "第二个sheet", null);
sheet2.setTableStyle(createTableStyle());
writer.write(createTestListJavaMode(), sheet2);
//写第三个sheet包含多个table情况
Sheet sheet3 = new Sheet(3, 0);
sheet3.setSheetName("第三个sheet");
Table table1 = new Table(1);
table1.setHead(createTestListStringHead());
writer.write1(createTestListObject(), sheet3, table1);
//写sheet2 模型上打有表头的注解
Table table2 = new Table(2);
table2.setTableStyle(createTableStyle());
table2.setClazz(JavaModel1.class);
writer.write(createTestListJavaMode(), sheet3, table2);
//关闭资源
writer.finish();
out.close();
2.表头不带注解的方法
这种dto的写法跟上述的dto写法基本相同，就是去掉了注解。也可以不用dto，直接用List来代替dto的作用，其他都一样。表头带注解的方法不用自己写表头，不带注解的方法需要自己去组装表头，但是这种方法可以去调整表头字段的宽度。带注解的方法表头会自适应一个宽度出来。

sheet1.setSheetName("第一个sheet");
//设置列宽 设置每列的宽度

sheet1.setHead(createTestListStringHead());
//or 设置自适应宽度
//sheet1.setAutoWidth(Boolean.TRUE);
writer.write1(createTestListObject(), sheet1);
//写第二个sheet sheet2 模型上打有表头的注解，合并单元格
Sheet sheet2 = new Sheet(2, 3, JavaModel1.class, "第二个sheet", null);
sheet2.setTableStyle(createTableStyle());
writer.write(createTestListJavaMode(), sheet2);
//写第三个sheet包含多个table情况

总结
以上举例是常用的两种组装数据成excel的方法，第一种适用常规的excel导出，但是表头不能控制，数据也必须跟dto中对应，限制相对大一点。第二种方法灵活行比较大，表头可以自己组装，数据也不用局限dto。在实际运用中就最大的不同就是第二种可以做动态列，但是由于第一种因为其局限性就无法完成动态列的实现，但是它却省了很多功夫来组装数据。两者各有优劣，就看实际的业务需求了。
当然还有同一个sheet中使用table来实现两部分数据块的展示方法等等，这些都可以从官方文档中找个具体的使用方法。这里就不做详细阐述了，本文主要就是讲解数据的组装逻辑方法。
