以下是一个使用Apache POI库在Java中导出Excel并插入三个附件的示例程序:
```java
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.common.usermodel.HyperlinkType;
import org.apache.poi.ss.usermodel.CellStyle;
import org.apache.poi.ss.usermodel.CreationHelper;
import org.apache.poi.ss.usermodel.Hyperlink;
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.XSSFCellStyle;
import org.apache.poi.xssf.usermodel.XSSFClientAnchor;
import org.apache.poi.xssf.usermodel.XSSFDrawing;
import org.apache.poi.xssf.usermodel.XSSFHyperlink;
import org.apache.poi.xssf.usermodel.XSSFPicture;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
public class ExcelWithAttachments {
public static void main(String[] args) throws IOException {
// 创建工作簿
Workbook workbook = new XSSFWorkbook();
CreationHelper creationHelper = workbook.getCreationHelper();
// 创建工作表
Sheet sheet = workbook.createSheet("附件列表");
// 创建单元格样式以使附件链接可见
XSSFCellStyle linkStyle = (XSSFCellStyle) workbook.createCellStyle();
linkStyle.setWrapText(true);
linkStyle.setVerticalAlignment(CellStyle.VERTICAL_CENTER);
// 创建标题行
Row headerRow = sheet.createRow(0);
headerRow.createCell(0).setCellValue("文件名");
headerRow.createCell(1).setCellValue("链接");
// 插入附件链接
for (int i = 0; i < 3; i++) {
// 获取附件信息
String fileName = "附件" + (i + 1) + ".txt";
String filePath = "D:\\" + fileName;
// 创建链接单元格
int rowNumber = i + 1;
Row row = sheet.createRow(rowNumber);
row.createCell(0).setCellValue(fileName);
XSSFHyperlink link = (XSSFHyperlink) creationHelper.createHyperlink(HyperlinkType.FILE);
link.setAddress(filePath);
row.createCell(1).setCellValue(filePath);
row.getCell(1).setHyperlink(link);
row.getCell(1).setCellStyle(linkStyle);
}
// 插入图片附件
XSSFDrawing drawing = (XSSFDrawing) sheet.createDrawingPatriarch();
for (int i = 0; i < 3; i++) {
// 获取图片附件信息
String fileName = "图片" + (i + 1) + ".jpg";
String filePath = "D:\\" + fileName;
// 创建图片单元格
int rowNumber = i + 4;
Row row = sheet.createRow(rowNumber);
row.createCell(0).setCellValue(fileName);
XSSFClientAnchor anchor = new XSSFClientAnchor();
anchor.setCol1(1);
anchor.setRow1(rowNumber);
anchor.setCol2(2);
anchor.setRow2(rowNumber + 1);
XSSFPicture picture = drawing.createPicture(anchor, workbook.addPicture(
ExcelWithAttachments.class.getResourceAsStream(fileName), XSSFWorkbook.PICTURE_TYPE_JPEG));
XSSFHyperlink link = (XSSFHyperlink) creationHelper.createHyperlink(HyperlinkType.FILE);
link.setAddress(filePath);
picture.getClientAnchor().setAnchorType(2);
picture.getCTPicture().getBlipFill().getBlip().setEmbed(workbook.getAllPictures().get(0).getPackageRelationship().getId());
row.createCell(1).setCellValue(filePath);
row.getCell(1).setHyperlink(link);
row.getCell(1).setCellStyle(linkStyle);
}
// 将工作簿写入文件
FileOutputStream outputStream = new FileOutputStream("附件列表.xlsx");
workbook.write(outputStream);
workbook.close();
}
}
```
这个程序将创建一个名为“附件列表”的Excel工作表,并在其中插入三个文本附件和三个图片附件。每个附件都将在工作表中作为链接显示,并且可以单击链接打开附件。请确保将附件文件存储在程序中指定的目录中。
