可以使用Apache POI和iText库来实现将Word文档转换为PDF格式。
首先,需要添加以下依赖:
```xml
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>4.1.2</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>4.1.2</version>
</dependency>
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
<version>5.5.13</version>
</dependency>
```
然后,可以按照以下步骤来实现转换:
1. 读取Word文档:
```java
InputStream inputStream = new FileInputStream(new File("input.docx"));
XWPFDocument document = new XWPFDocument(inputStream);
```
2. 创建PDF文档:
```java
Document pdfDoc = new Document();
PdfWriter.getInstance(pdfDoc, new FileOutputStream(new File("output.pdf")));
pdfDoc.open();
```
3. 将Word文档中的内容逐段写入PDF文档:
```java
List<XWPFParagraph> paragraphs = document.getParagraphs();
for (XWPFParagraph para : paragraphs) {
List<XWPFRun> runs = para.getRuns();
for (XWPFRun run : runs) {
String text = run.getText(0);
if (text != null) {
pdfDoc.add(new Paragraph(text));
}
}
}
```
4. 关闭文档:
```java
pdfDoc.close();
```
完整代码示例:
```java
import com.itextpdf.text.Document;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import java.io.*;
public class WordToPdfConverter {
public static void main(String[] args) throws Exception {
// 读取Word文档
InputStream inputStream = new FileInputStream(new File("input.docx"));
XWPFDocument document = new XWPFDocument(inputStream);
// 创建PDF文档
Document pdfDoc = new Document();
PdfWriter.getInstance(pdfDoc, new FileOutputStream(new File("output.pdf")));
pdfDoc.open();
// 将Word文档中的内容逐段写入PDF文档
for (XWPFParagraph para : document.getParagraphs()) {
for (XWPFRun run : para.getRuns()) {
String text = run.getText(0);
if (text != null) {
pdfDoc.add(new Paragraph(text));
}
}
}
// 关闭文档
pdfDoc.close();
}
}
```
