今天小编给大家分享一下Java操作excel的三种常见方法是什么的相关知识点,内容详细,逻辑清晰,相信大部分人都还太了解这方面的知识,所以分享这篇文章给大家参考一下,希望大家阅读完这篇文章后有所收获,下面我们一起来了解一下吧。
常用方法:
apache poi
easypoi
easyexcel
大概在很久很久以前,微软的电子表格软件 Excel 以操作简单、存储数据直观方便,还支持打印报表,在诞生之初,可谓深得办公室里的白领青睐,极大的提升了工作的效率,不久之后,便成了办公室里的必备工具。
随着更多的新语言的崛起,例如我们所熟悉的 java,后来便有一些团队开始开发一套能与 Excel 软件无缝切换的操作工具!
当然,在java生态体系里面,能与Excel无缝衔接的第三方工具还有很多,在开始也给大家列出来三个,因为 apache poi 在业界使用的最广泛,因此其他的工具不做过多介绍!
话不多说,直接开撸!

导出操作,即使用 Java 写出数据到 Excel 中,常见场景是将页面上的数据导出,这些数据可能是财务数据,也可能是商品数据,生成 Excel 后返回给用户下载文件。
在 poi 工具库中,导出 api 可以分三种方式
HSSF方式: 这种方式导出的文件格式为office 2003专用格式,即.xls,优点是导出数据速度快,但是 最多65536行 数据
XSSF方式: 这种方式导出的文件格式为office 2007专用格式,即.xlsx,优点是导出的数据不受行数限制,缺点导出速度慢
SXSSF方式: SXSSF 是 XSSF API的兼容流式扩展,主要解决当使用 XSSF 方式导出大数据量时,内存溢出的问题,支持导出大批量的excel数据
HSSF方式,最多只支持65536条数据导出,超过这个条数会报错!
package cn.tedu.excel.test;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import java.io.FileOutputStream;
/**
* HSSF方式导出:HSSF方式,最多只支持65536条数据导出,超过这个条数会报错!
* 就是.xls模式
*/
public class ExcelWrite2003Test {
private static String PATH = "/Users/lixin/Desktop/";//自己输出的路径
public static void main(String[] args) throws Exception {
//时间
long begin = System.currentTimeMillis();
//创建一个工作簿
Workbook workbook = new HSSFWorkbook();
//创建表
Sheet sheet = workbook.createSheet();
//写入数据
for (int rowNumber = 0; rowNumber < 65536; rowNumber++) {
//创建行
Row row = sheet.createRow(rowNumber);
for (int cellNumber = 0; cellNumber < 10; cellNumber++) {
//创建列
Cell cell = row.createCell(cellNumber);
cell.setCellValue(cellNumber);
}
}
System.out.println("结束!");
FileOutputStream fileOutputStream = new FileOutputStream(PATH + "用户信息表-XLS.xls");
workbook.write(fileOutputStream);
fileOutputStream.close();
long end = System.currentTimeMillis();
System.out.println("时间为:"+(double) (end - begin) / 1000);//2.262s
}
}
XSSF方式支持大批量数据导出,所有的数据先写入内存再导出,容易出现内存溢出!
package cn.tedu.excel.test;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import java.io.FileOutputStream;
/**
* .xlsx方式
*/
public class ExcelWrite2007Test {
public static String PATH = "/Users/lixin/Desktop/";
public static void main(String[] args) throws Exception {
//时间
long begin = System.currentTimeMillis();
//创建一个工作簿
Workbook workbook = new XSSFWorkbook();
//创建表
Sheet sheet = workbook.createSheet();
//写入数据
for (int rowNumber = 0; rowNumber < 65537; rowNumber++) {
Row row = sheet.createRow(rowNumber);
for (int cellNumber = 0; cellNumber < 10; cellNumber++) {
Cell cell = row.createCell(cellNumber);
cell.setCellValue(cellNumber);
}
}
System.out.println("结束");
FileOutputStream fileOutputStream = new FileOutputStream(PATH + "用户信息表-XLSX.xlsx");
workbook.write(fileOutputStream);
fileOutputStream.close();
long end = System.currentTimeMillis();
System.out.println((double) (end - begin) / 1000);//5.003s
}
}
SXSSF方式是XSSF方式的一种延伸,主要特性是低内存,导出的时候,先将数据写入磁盘再导出,避免报内存不足,导致程序运行异常,缺点是运行很慢!
package cn.tedu.excel.test;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.streaming.SXSSFWorkbook;
import java.io.FileOutputStream;
public class ExcelWriteSXSSFTest {
public static String PATH = "/Users/lixin/Desktop/";
public static void main(String[] args) throws Exception {
//时间
long begin = System.currentTimeMillis();
//创建一个工作簿
Workbook workbook = new SXSSFWorkbook();
//创建表
Sheet sheet = workbook.createSheet();
//写入数据
for (int rowNumber = 0; rowNumber < 100000; rowNumber++) {
Row row = sheet.createRow(rowNumber);
for (int cellNumber = 0; cellNumber < 10; cellNumber++) {
Cell cell = row.createCell(cellNumber);
cell.setCellValue(cellNumber);
}
}
System.out.println("over");
FileOutputStream fileOutputStream = new FileOutputStream(PATH + "用户信息表-SXSSF.xlsx");
workbook.write(fileOutputStream);
fileOutputStream.close();
long end = System.currentTimeMillis();
System.out.println((double) (end - begin) / 1000);//6.39s
}
}
导入操作,即将 excel 中的数据采用java工具库将其解析出来,进而将 excel 数据写入数据库!
同样,在 poi 工具库中,导入 api 也分三种方式,与上面的导出一一对应!
package cn.tedu.excel.test;

public static void main(String[] args) throws Exception {
//获取文件流
FileInputStream inputStream = new FileInputStream(PATH + "用户信息表2003read.xls");
//1.创建工作簿,使用excel能操作的这边都看看操作
Workbook workbook = new HSSFWorkbook(inputStream);
//2.得到表
Sheet sheet = workbook.getSheetAt(0);
//3.得到行
Row row = sheet.getRow(0);
//4.得到列
Cell cell = row.getCell(0);
getValue(cell);
inputStream.close();
}
public static void getValue(Cell cell){
//匹配类型数据
if (cell != null) {
CellType cellType = cell.getCellType();
String cellValue = "";
switch (cellType) {

cellValue = cell.getStringCellValue();
break;

cellValue = String.valueOf(cell.getBooleanCellValue());
break;

if (HSSFDateUtil.isCellDateFormatted(cell)) { //日期
System.out.print("[日期]");
Date date = cell.getDateCellValue();
cellValue = new DateTime(date).toString("yyyy-MM-dd");
} else {
//不是日期格式,防止数字过长
System.out.print("[转换为字符串输出]");
cell.setCellType(CellType.STRING);
cellValue = cell.toString();
}
break;
case ERROR:
System.out.print("[数据类型错误]");
break;
}
System.out.println(cellValue);
}
}

以前的以前,有个大佬程序员,跳到一家公司之后就和业务人员聊上了,这些业务员对excel报表有着许许多多的要求,比如想要一个报表,他的表头是一个多行表头,过几天之后,他想要给这些表头添加样式,比如关键的数据标红,再过几天,他想要再末尾添加一条合计的数据,等等!
起初还好,都是copy、copy,之后发现系统中出现大量的重复代码,于是有一天真的忍受不了了,采用注解搞定来搞定这些定制化成程度高的逻辑,将公共化抽离出来,于是诞生了 easypoi!它的底层也是基于 apache poi 进行深度开发的,它主要的特点就是将更多重复的工作,全部简单化,避免编写重复的代码!
下面,我们就一起来了解一下这款高大上的开源工具:easypoi

easypoi 最大的亮点就是基于注解实体类来导出、导入excel,使用起来非常简单!
我们创建一个实体类UserEntity,其中@Excel注解表示导出文件的头部信息。
添加Lombok插件,替代set和get方法
package cn.tedu.excel.easypoi;
import cn.afterturn.easypoi.excel.ExcelExportUtil;
import cn.afterturn.easypoi.excel.annotation.Excel;
import cn.afterturn.easypoi.excel.entity.ExportParams;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.apache.poi.ss.usermodel.Workbook;
import java.io.FileOutputStream;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
@Data
@NoArgsConstructor
@AllArgsConstructor
public class UserEntity {
@Excel(name = "姓名")
private String name;
@Excel(name = "年龄")
private int age;
@Excel(name = "操作时间",format="yyyy-MM-dd HH:mm:ss", width = 20.0)
private Date time;
public static void main(String[] args) throws Exception {
List<UserEntity> dataList = new ArrayList<>();
for (int i = 0; i < 10; i++) {
UserEntity userEntity = new UserEntity();
userEntity.setName("张三" + i);
userEntity.setAge(20 + i);
userEntity.setTime(new Date(System.currentTimeMillis() + i));
dataList.add(userEntity);
}
//生成excel文档
Workbook workbook = ExcelExportUtil.exportExcel(new ExportParams("用户","用户信息"),
UserEntity.class, dataList);
FileOutputStream fos = new FileOutputStream("/Users/lixin/Desktop/easypoi-user.xls");
workbook.write(fos);
fos.close();
}
}
package cn.tedu.excel.easypoi;
import cn.afterturn.easypoi.excel.ExcelImportUtil;
import cn.afterturn.easypoi.excel.annotation.Excel;
import cn.afterturn.easypoi.excel.entity.ImportParams;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.io.File;
import java.util.Date;
import java.util.List;
import org.json.simple.JSONArray;
@Data
@NoArgsConstructor
@AllArgsConstructor
public class StudentEntity {
@Excel(name = "姓名")
private String name;
@Excel(name = "年龄")
private int age;
@Excel(name = "操作时间",format="yyyy-MM-dd HH:mm:ss", width = 20.0)
private Date time;
public static void main(String[] args) {
ImportParams params = new ImportParams();
params.setTitleRows(1);
params.setHeadRows(1);
long start = new Date().getTime();
List<StudentEntity> list = ExcelImportUtil.importExcel(new File("/Users/lixin/Desktop/easypoi-user1.xls"),
UserEntity.class, params);
System.out.println(new Date().getTime() - start);
System.out.println(JSONArray.toJSONString(list));
}
}
输出结果为:
[UserEntity(name=张三0, age=20, time=Mon Mar 29 11:29:52 CST 2021),UserEntity(name=李四, age=21, time=Mon Mar 29 11:29:52 CST 2021),UserEntity(name=王武, age=22, time=Mon Mar 29 11:29:52 CST 2021),UserEntity(name=赵六, age=23, time=Mon Mar 29 11:29:52 CST 2021),UserEntity(name=null, age=0, time=null),UserEntity(name=null, age=0, time=null),UserEntity(name=null, age=0, time=null),UserEntity(name=null, age=0, time=null),UserEntity(name=null, age=0, time=null),UserEntity(name=null, age=0, time=null)]
easypoi 同样也支持自定义数据结构导出导入excel。
自定义数据导出 excel
public static void main(String[] args) throws Exception {
//封装表头
List<ExcelExportEntity> entityList = new ArrayList<ExcelExportEntity>();
entityList.add(new ExcelExportEntity("姓名", "name"));
entityList.add(new ExcelExportEntity("年龄", "age"));
ExcelExportEntity entityTime = new ExcelExportEntity("操作时间", "time");
entityTime.setFormat("yyyy-MM-dd HH:mm:ss");
entityTime.setWidth(20.0);
entityList.add(entityTime);
//封装数据体
List<Map<String, Object>> dataList = new ArrayList<>();
for (int i = 0; i < 10; i++) {
Map<String, Object> userEntityMap = new HashMap<>();
userEntityMap.put("name", "张三" + i);
userEntityMap.put("age", 20 + i);
userEntityMap.put("time", new Date(System.currentTimeMillis() + i));
dataList.add(userEntityMap);
}
//生成excel文档
Workbook workbook = ExcelExportUtil.exportExcel(new ExportParams("学生","用户信息"), entityList, dataList);
FileOutputStream fos = new FileOutputStream("/Users/lixin/Desktop/easypoi-user2.xls");
workbook.write(fos);
fos.close();
}
public static void main(String[] args) {
ImportParams params = new ImportParams();
params.setTitleRows(1);
params.setHeadRows(1);
long start = new Date().getTime();
List<Map<String, Object>> list = ExcelImportUtil.importExcel(new File("/Users/lixin/Desktop/easypoi-user2.xls"),
Map.class, params);
System.out.println(new Date().getTime() - start);
System.out.println(JSONArray.toJSONString(list));
}
easyexcel 是阿里巴巴开源的一款 excel 解析工具,底层逻辑也是基于 apache poi 进行二次开发的。不同的是,再读写数据的时候,采用 sax 模式一行一行解析,在并发量很大的情况下,依然能稳定运行!
下面,我们就一起来了解一下这款新起之秀!

easyexcel 同样也支持采用注解方式进行导出、导入!
首先,我们创建一个实体类UserEntity,其中@ExcelProperty注解表示导出文件的头部信息。
package cn.tedu.excel.easyexcel;
import com.alibaba.excel.EasyExcel;
import com.alibaba.excel.annotation.ExcelProperty;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.format.annotation.DateTimeFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
@Data
@NoArgsConstructor
@AllArgsConstructor
public class UserEntity {
@ExcelProperty(value = "姓名")
private String name;
@ExcelProperty(value = "年龄")
private int age;
@DateTimeFormat(fallbackPatterns = "yyyy-MM-dd HH:mm:ss")
@ExcelProperty(value = "操作时间")
private Date time;
public static void main(String[] args) {
List<UserEntity> dataList = new ArrayList<>();
for (int i = 0; i < 10; i++) {
UserEntity userEntity = new UserEntity();
userEntity.setName("张三" + i);
userEntity.setAge(20 + i);
userEntity.setTime(new Date(System.currentTimeMillis() + i));
dataList.add(userEntity);
}
EasyExcel.write("/Users/lixin/Desktop/easyexcel-user1.xls", UserEntity.class).sheet("用户信息").doWrite(dataList);
}
}
3.2.2 导入操作
package cn.tedu.excel.easyexcel;
import com.alibaba.excel.EasyExcel;
import org.json.simple.JSONArray;
import java.util.List;
public class DemoData {
public static void main(String[] args) {
String filePath = "/Users/lixin/Desktop/easyexcel-user1.xls";
List<DemoData> list = EasyExcel.read(filePath).head(UserEntity.class).sheet().doReadSync();
System.out.println(JSONArray.toJSONString(list));
}
}
结果显示:
[UserEntity(name=张三0, age=20, time=Mon Mar 29 16:42:20 CST 2021),UserEntity(name=张三1, age=21, time=Mon Mar 29 16:42:20 CST 2021),UserEntity(name=张三2, age=22, time=Mon Mar 29 16:42:20 CST 2021),UserEntity(name=张三3, age=23, time=Mon Mar 29 16:42:20 CST 2021),UserEntity(name=张三4, age=24, time=Mon Mar 29 16:42:20 CST 2021),UserEntity(name=张三5, age=25, time=Mon Mar 29 16:42:20 CST 2021),UserEntity(name=张三6, age=26, time=Mon Mar 29 16:42:20 CST 2021),UserEntity(name=张三7, age=27, time=Mon Mar 29 16:42:20 CST 2021),UserEntity(name=张三8, age=28, time=Mon Mar 29 16:42:20 CST 2021),UserEntity(name=张三9, age=29, time=Mon Mar 29 16:42:20 CST 2021)]
easyexcel 同样也支持自定义数据结构导出导入excel。
public static void main(String[] args) {
//表头
List<List<String>> headList = new ArrayList<>();
headList.add(Lists.newArrayList("姓名"));
headList.add(Lists.newArrayList("年龄"));
headList.add(Lists.newArrayList("操作时间"));
//数据体
List<List<Object>> dataList = new ArrayList<>();
for (int i = 0; i < 10; i++) {
List<Object> data = new ArrayList<>();
data.add("张三" + i);
data.add(20 + i);
data.add(new Date(System.currentTimeMillis() + i));
dataList.add(data);
}
EasyExcel.write("/Users/hello/Documents/easyexcel-user2.xls").head(headList).sheet("用户信息").doWrite(dataList);
}
public static void main(String[] args) {
String filePath = "/Users/panzhi/Documents/easyexcel-user2.xls";
UserDataListener userDataListener = new UserDataListener();
EasyExcel.read(filePath, userDataListener).sheet().doRead();
System.out.println("表头:" + JSONArray.toJSONString(userDataListener.getHeadList()));
System.out.println("数据体:" + JSONArray.toJSONString(userDataListener.getDataList()));
}
运行结果如下所示:
表头:[{0:"姓名",1:"年龄",2:"操作时间"}]
数据体:[{0:"张三0",1:"20",2:"2021-03-29 16:31:39"},{0:"张三1",1:"21",2:"2021-03-29 16:31:39"},{0:"张三2",1:"22",2:"2021-03-29 16:31:39"},{0:"张三3",1:"23",2:"2021-03-29 16:31:39"},{0:"张三4",1:"24",2:"2021-03-29 16:31:39"},{0:"张三5",1:"25",2:"2021-03-29 16:31:39"},{0:"张三6",1:"26",2:"2021-03-29 16:31:39"},{0:"张三7",1:"27",2:"2021-03-29 16:31:39"},{0:"张三8",1:"28",2:"2021-03-29 16:31:39"},{0:"张三9",1:"29",2:"2021-03-29 16:31:39"}]
