pom.xml
文件中添加以下依赖:<dependencies>
<!-- Apache POI -->
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>4.1.2</version>
</dependency>
<!-- Apache PDFBox -->
<dependency>
<groupId>org.apache.pdfbox</groupId>
<artifactId>pdfbox</artifactId>
<version>2.0.25</version>
</dependency>
</dependencies>
WordToPdfConverter
。在该类中,你需要编写一个方法来执行Word到PDF的转换操作。以下是一个例子:import org.apache.poi.xwpf.converter.pdf.PdfConverter;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import java.io.*;
public class WordToPdfConverter {
public void convertToPdf(File wordFile, File pdfFile) throws IOException {
try (InputStream in = new FileInputStream(wordFile);
OutputStream out = new FileOutputStream(pdfFile)) {
XWPFDocument document = new XWPFDocument(in);
PdfConverter.getInstance().convert(document, out, null);
}
}
}
WordToPdfConverter
类中的方法。例如:import org.springframework.stereotype.Service;
@Service
public class FileConversionService {
private final WordToPdfConverter converter;
public FileConversionService(WordToPdfConverter converter) {
this.converter = converter;
}
public void convertWordToPdf(File wordFile, File pdfFile) throws IOException {
converter.convertToPdf(wordFile, pdfFile);
}
}
FileConversionService
。import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.multipart.MultipartFile; import java.io.File; import java.io.IOException; @RestController public class FileConversionController { private final FileConversionService conversionService; public FileConversionController(FileConversionService conversionService) { this.conversionService = conversionService; } @PostMapping("/convert") public String convertWordToPdf(@RequestParam("file") MultipartFile file) { try { File wordFile = File.createTempFile("word", ".docx"); file.transferTo(wordFile); File pdfFile = File.createTempFile("pdf", ".pdf"); conversionService.convertWordToPdf(wordFile, pdfFile); // 返回PDF文件路径或其他相关信息 return pdfFile.getAbsolutePath(); } catch (IOException e) { e.printStackTrace(); // 错误处理 return "转换失败:" + e.getMessage(); } } }
以上便是一个基本的Spring Boot代码示例,用于将Word文件转换为PDF。你可以根据自己的需求进行修改和扩展。记得在实际的开发中,需要适当处理文件命名和路径,以及错误情况的处理。
