可以使用Apache POI库来实现Java向Word中插入Excel附件的功能。具体步骤如下:
1. 引入POI库的依赖,例如在Maven项目中,可以在pom.xml文件中添加以下依赖:
```xml
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>4.1.2</version>
</dependency>
```
2. 使用POI库创建Excel文件,并将其保存到本地磁盘上,例如:
```java
Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Sheet1");
Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue("Hello, Excel!");
FileOutputStream fos = new FileOutputStream("example.xlsx");
workbook.write(fos);
fos.close();
```
3. 使用Java的File对象创建Excel文件的输入流,然后使用POI库的WorkbookFactory类读取Excel文件,例如:
```java
File excelFile = new File("example.xlsx");
FileInputStream fis = new FileInputStream(excelFile);
Workbook workbook = WorkbookFactory.create(fis);
```
4. 使用POI库的ByteArrayOutputStream类将Excel文件转换为字节数组,例如:
```java
ByteArrayOutputStream bos = new ByteArrayOutputStream();
workbook.write(bos);
byte[] excelBytes = bos.toByteArray();
```
5. 使用POI库的XWPFDocument类创建Word文档,并将Excel文件作为附件插入到文档中,例如:
```java
XWPFDocument document = new XWPFDocument();
XWPFParagraph paragraph = document.createParagraph();
XWPFRun run = paragraph.createRun();
run.setText("This is a Word document with an Excel attachment.");
XWPFParagraph attachmentParagraph = document.createParagraph();
XWPFRun attachmentRun = attachmentParagraph.createRun();
attachmentRun.addBreak();
attachmentRun.setText("Excel Attachment:");
XWPFRun attachmentRun2 = attachmentParagraph.createRun();
attachmentRun2.addPicture(new ByteArrayInputStream(excelBytes), XWPFDocument.PICTURE_TYPE_JPEG, "example.xlsx", Units.toEMU(300), Units.toEMU(200));
FileOutputStream fos = new FileOutputStream("example.docx");
document.write(fos);
fos.close();
```
以上代码将创建一个Word文档,其中包含一个Excel附件。在运行时,请确保已经在classpath中包含poi和poi-ooxml库。
