1：添加依賴

2：編寫轉換的方法

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.text.PDFTextStripper;

import java.io.*;

/**
 * 把pdf轉換為word格式
 *
 * @author Angin
 * @date 2019/3/18 0018.
 */
public class PdfToWord {
    /**
     * 轉換
     */
    public void convertText(String pdfPath) {
        PDDocument doc 
 
= null;
        OutputStream fos = null;
        Writer writer = null;
        PDFTextStripper stripper = null;
        try {
            doc = PDDocument.load(new File(pdfPath));
            fos = new FileOutputStream(pdfPath.substring(0, pdfPath.indexOf(".")) + ".doc");
            writer = new
 
 OutputStreamWriter(fos, "UTF-8");
            stripper = new PDFTextStripper();
            int pageNumber = doc.getNumberOfPages();
            stripper.setSortByPosition(true);
            stripper.setStartPage(1);
            stripper.setEndPage(pageNumber);
            stripper.writeText(doc, writer);
            writer.close();
            doc.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println("end..");
    }
}

3：main方法中進行測試

/**
 * main方法測試
 * @author Angin
 * @date 2019/3/18 0018.
 */
public class MainClass {
    public static void main(String[] args) {
   PdfToWord convert=new PdfToWord();
   convert.convertText("E:\\pdfToWord.pdf");
    }
}

此方法只適合文檔型的pdf轉換，如果圖片的話，轉換後無法讀取。

java實現pdf轉word(文字)
