java POI 插入图片到Excel文件

1.添加POI依赖

<dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>3.17</version></dependency><!-- /artifact/org.apache.poi/poi-ooxml --><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>3.17</version></dependency>

2.使用XSSFDrawing 插入图片到excel文件

参考java POI实现向Excel中插入图片 java 在Excel中插入图片 POI实现

XSSFDrawing patri = (XSSFDrawing) sheet.createDrawingPatriarch();// col1,row1 开始单元格 列和行,从0下标开始// col2,row2 开始单元格 列和行,从1下标开始XSSFClientAnchor anchor = new XSSFClientAnchor(0, 0, 255, 255, col1, row1, col2, row2);patri.createPicture(anchor, workbook.addPicture(byteArrayOut.toByteArray(), XSSFWorkbook.PICTURE_TYPE_PNG));
