可以使用Apache POI库来实现使用Java导出Excel,并且可以使用Java Graphics2D类来插入印章。具体实现可以参考以下代码:
```java
// 导出Excel
Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Sheet1");
Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue("Hello World!");
FileOutputStream outputStream = new FileOutputStream("output.xlsx");
workbook.write(outputStream);
outputStream.close();
// 插入印章
BufferedImage image = ImageIO.read(new File("seal.png"));
Graphics2D graphics = image.createGraphics();
graphics.setFont(new Font("宋体", Font.BOLD, 20));
graphics.drawString("印章文字", 50, 100);
ImageIO.write(image, "png", new File("seal_with_text.png"));
```
注意:需要将印章图片放在项目目录下,并且需要引入Apache POI和Java Graphics2D类。
