springboot实现word转pdf

Spring Boot可以使用Apache POI和iText库来实现Word转PDF的功能。

1. 首先，需要在pom.xml文件中添加以下依赖：

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>4.1.2</version>
</dependency>

<dependency>
    <groupId>com.itextpdf</groupId>
    <artifactId>itextpdf</artifactId>
    <version>5.5.13.2</version>
</dependency>

2. 接下来，需要编写一个Word转PDF的工具类。以下是一个简单的示例：

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;

import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;

import com.itextpdf.text.Document;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;

public class WordToPdfConverter {

    public static void convert(String inputPath, String outputPath) throws Exception {
        InputStream inputStream = new FileInputStream(new File(inputPath));
        XWPFDocument document = new XWPFDocument(inputStream);

        OutputStream outputStream = new FileOutputStream(new File(outputPath));
        Document pdfDocument = new Document();
        PdfWriter.getInstance(pdfDocument, outputStream);

        pdfDocument.open();
        for (XWPFParagraph paragraph : document.getParagraphs()) {
            for (XWPFRun run : paragraph.getRuns()) {
                String text = run.getText();
                if (text != null) {
                    Paragraph pdfParagraph = new Paragraph(text);
                    pdfDocument.add(pdfParagraph);
                }
            }
        }
        pdfDocument.close();
        outputStream.close();
        inputStream.close();
    }
}

3. 最后，在Spring Boot应用程序中调用该工具类即可实现Word转PDF的功能。以下是一个简单的示例：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) throws Exception {
        WordToPdfConverter.convert("input.docx", "output.pdf");
        SpringApplication.run(Application.class, args);
    }
}

注意：在实际使用中，需要根据具体的需求进行适当的修改和优化。
