Easyexcel插入图片
旭东怪 人气:0各位今天给大家分享Easyexcel 实现批量插入图片的问题，代码如下所示：
1 Maven依赖
<!--hutool工具包-->
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>
<version>5.5.1</version>
</dependency>
<!--easyexcel文档处理工具-->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>easyexcel</artifactId>
<version>2.2.8</version>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>2 PictureModel
图片信息。
package com.xudongbase.easyexcel.model;
import com.xudongbase.easyexcel.model.builder.PictureModelBuilder;
import com.xudongbase.easyexcel.model.common.SheetRangeModel;
import lombok.Getter;
/**
* 图片信息
*
* @author xudongmaster
*/
@Getter
public class PictureModel extends SheetRangeModel {
/**
* 图片数据
*/
private byte[] pictureBytes;
* 图片类型
private Integer pictureType;
public PictureModel(PictureModelBuilder builder) {
this.sheetName = builder.getSheetName();
this.startRowIndex = builder.getStartRowIndex();
this.endRowIndex = builder.getEndRowIndex();
this.startColumnIndex = builder.getStartColumnIndex();
this.endColumnIndex = builder.getEndColumnIndex();
this.pictureBytes = builder.getPictureBytes();
this.pictureType = builder.getPictureType();
}
* 生成图片信息
*
* @param sheetName sheet页名称
* @param startRowIndex 开始行号
* @param endRowIndex 结束行号
* @param startColumnIndex 开始列号
* @param endColumnIndex 结束列号
* @param pictureBytes 图片数据
* @return
public static PictureModel createPictureModel(String sheetName, int startRowIndex, int endRowIndex, int startColumnIndex, int endColumnIndex
, byte[] pictureBytes) {
return createPictureModel(sheetName, startRowIndex, endRowIndex, startColumnIndex, endColumnIndex, pictureBytes, null);
* @param pictureType 图片类型
, byte[] pictureBytes, Integer pictureType) {
return new PictureModelBuilder(sheetName, startRowIndex, endRowIndex, startColumnIndex, endColumnIndex, pictureBytes)
//图片类型
.pictureType(pictureType)
.build();
}3CustomPictureHandler
自定义图片处理器。
package com.xudongbase.easyexcel.handler;
import cn.hutool.core.collection.CollUtil;
import cn.hutool.core.util.StrUtil;
import com.alibaba.excel.write.handler.SheetWriteHandler;
import com.alibaba.excel.write.metadata.holder.WriteSheetHolder;
import com.alibaba.excel.write.metadata.holder.WriteWorkbookHolder;
import com.xudongbase.common.poi.util.POIExcelUtil;
import com.xudongbase.easyexcel.model.PictureModel;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;
/**
* 自定义图片处理器
*
* @author xudongmaster
*/
public class CustomPictureHandler implements SheetWriteHandler {
/**
* sheet页名称列表
*/
private List<String> sheetNameList;
* 图片信息
private List<PictureModel> pictureList = new ArrayList<>();
public CustomPictureHandler(List<PictureModel> pictureList) {
if (CollUtil.isEmpty(pictureList)) {
return;
}
this.pictureList = pictureList.stream().filter(x ->
StrUtil.isNotBlank(x.getSheetName()) && x.getPictureBytes() != null && x.getPictureBytes().length > 0)
.collect(Collectors.toList());
sheetNameList = this.pictureList.stream().map(x -> x.getSheetName()).distinct().collect(Collectors.toList());
}
@Override
public void beforeSheetCreate(WriteWorkbookHolder writeWorkbookHolder, WriteSheetHolder writeSheetHolder) {
* sheet页创建之后调用
*
* @param writeWorkbookHolder
* @param writeSheetHolder
public void afterSheetCreate(WriteWorkbookHolder writeWorkbookHolder, WriteSheetHolder writeSheetHolder) {
Sheet sheet = writeSheetHolder.getSheet();
//不需要添加图片，或者当前sheet页不需要添加图片
if (CollUtil.isEmpty(pictureList) || sheetNameList.contains(sheet.getSheetName()) == false) {
//获取当前sheet的图片
List<PictureModel> sheetPictureList = pictureList.stream().filter(x ->
StrUtil.equals(x.getSheetName(), sheet.getSheetName())
).collect(Collectors.toList());
//当前sheet页不需要图片
if (CollUtil.isEmpty(sheetPictureList)) {
for (PictureModel pictureModel : sheetPictureList) {
//图片数据
byte[] pictureBytes = pictureModel.getPictureBytes();
//插入图片
POIExcelUtil.insertImg(writeWorkbookHolder.getWorkbook(), sheet, pictureBytes, pictureModel.getStartRowIndex()
, pictureModel.getEndRowIndex(), pictureModel.getStartColumnIndex(), pictureModel.getEndColumnIndex()
, (pictureModel.getPictureType() == null ? Workbook.PICTURE_TYPE_JPEG : pictureModel.getPictureType()));
//删除图片信息
pictureList.removeAll(sheetPictureList);
sheetNameList = pictureList.stream().map(x -> x.getSheetName()).distinct().collect(Collectors.toList());
}4 调试代码
/**
* 测试设置图片
*/
@Test
public void testPicture() {
try {
File file = new File("D:/easyexcel/testPicture.xlsx");
FileUtil.createNewFile(file);
//生成表格数据
List<List<Object>> dataList = new ArrayList<>();
dataList.add(new ArrayList<>(Arrays.asList(new Object[]{"表头11", "表头2", "表头3", "表头4"})));
dataList.add(new ArrayList<>(Arrays.asList(new Object[]{"表头17777777777", "表头2", "表头3", "表头4444"})));
dataList.add(new ArrayList<>(Arrays.asList(new Object[]{"表头31", "表头2", "表头3", "表头4"})));
dataList.add(new ArrayList<>(Arrays.asList(new Object[]{11.111, 11.111, "11.111", "表头4"})));
//导出文件
List<PictureModel> pictureModelList = new ArrayList<>();
String imgUrl = "http://profile.csdnimg.cn/9/5/B/1_qq_38974638";
byte[] bytes = HttpUtil.downloadBytes(imgUrl);
String sheetName="模板";
pictureModelList.add(PictureModel.createPictureModel(sheetName,0,10,0,4,bytes));
pictureModelList.add(PictureModel.createPictureModel(sheetName,11,22,0,4,bytes));
FileOutputStream fileOutputStream = new FileOutputStream(file);
ExcelWriter excelWriter = EasyExcel.write(fileOutputStream)
.inMemory(Boolean.TRUE).registerWriteHandler(new CustomPictureHandler(pictureModelList)).build();
WriteSheet writeSheet = EasyExcel.writerSheet(sheetName).build();
excelWriter.write(dataList, writeSheet);
//千万别忘记finish 会帮忙关闭流
excelWriter.finish();
} catch (Exception e) {
e.printStackTrace();
}
}5 调试结果
注：
1、 注册自定义处理器之前必须调用inMemory(Boolean.TRUE)方法。
2、觉得这篇博客写的不错的可以前往Gitee点个Star，源码请查看Gitee的xudongbase项目easyexcel分支。
补充：下面给大家分享基于python语言写的日常小工具向excel中批量添加图片和图片名称
需求：现有一个200张图片的文件夹，向 excel 中 A列，写入图片的名称，向ecxel 中的 E 列插入对应的图片。
from openpyxl import load_workbook
from openpyxl.drawing.image import Image
import os
import re
def insert_img_to_excel(filname, by_col,to_col,img_folder):
'''
filename : 表格文件路径
by_col : 依靠哪一列
to_col : 插入到哪一列
img_folder : 图片路径
wb = load_workbook(filname)
ws = wb.active
# 获取图片名称
img_fnn = os.listdir(str(img_folder))
index = 1
# 将图片名称写入到 excel 中 A 列
for img_fp in img_fnn:
s= img_fp.replace(".jpg",'')
index += 1
i = 'A' + str(index)
ws[i].value = s
wb.save(filname)
wb.close()
for ind , c in enumerate(ws[by_col],start=1):
# 图片文件的绝对路径
img_lujin = os.path.join(img_folder,c.value + '.jpg')
try:
# 设置图片大小
img_size = Image(img_lujin)
newsize = (150, 200)
img_size.width, img_size.height = newsize
# 将图片写入 excel
ws.add_image(
img_size,
anchor=to_col + str(ind)
)
except:
print(c.value,'匹配不到图片')
wb.save(filname)
if __name__ == '__main__':
insert_img_to_excel(
filname = r'C:\Users\Administrator\Desktop\act_test\mod.xlsx',
by_col = 'A',
to_col = 'E',
img_folder=r"C:\Users\Administrator\Desktop\act_test\Act_img"
)加载全部内容
