Java版PDF拼接

首先确保pom.xml文件中是否存在对应配置信息

<dependency>
    <groupId>org.apache.pdfbox</groupId>
    <artifactId>pdfbox</artifactId>
    <version>2.0.27</version>
</dependency>

代码部分直接复制下方代码

import org.apache.pdfbox.multipdf.PDFMergerUtility;

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class PDFMerger {

    public static void main(String[] args) {
        List<String> pdfFiles = new ArrayList<>();
        // 文件1信息
        pdfFiles.add("/Users/george/Downloads/1.pdf");
        // 文件2信息
        pdfFiles.add("/Users/george/Downloads/2.pdf");
        // 拼接后的文件信息
        String outputFile = "/Users/george/Downloads/拼接版PDF.pdf";

        try {
            // 处理PDF文件
            mergePDFs(pdfFiles, outputFile);
            System.out.println("PDF files merged successfully!");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void mergePDFs(List<String> pdfFiles, String outputFile) throws IOException {
        PDFMergerUtility pdfMerger = new PDFMergerUtility();
        for (String pdfFile : pdfFiles) {
            pdfMerger.addSource(new File(pdfFile));
        }
        pdfMerger.setDestinationFileName(outputFile);
        pdfMerger.mergeDocuments(null);
    }
}
