核心代码实现（单类）

 
import com.aspose.pdf.Document;
import com.aspose.pdf.SaveFormat;
import com.aspose.pdf.devices.PngDevice;
import com.aspose.pdf.devices.Resolution;

import java.io.*;

public class PDFHelper3 {

  public static void main(String[] args) throws IOException {
      pdf2image("C:\\Users\\liuya\\Desktop\\pdf\\示例文件.pdf");
  }


  //转word
  public static void pdf2word(String pdfPath) {
      long old = System.currentTimeMillis();
      try {
          String wordPath=pdfPath.substring(0,pdfPath.lastIndexOf("."))+".docx";
          FileOutputStream os = new FileOutputStream(wordPath);
          Document doc = new Document(pdfPath);
          doc.save(os, SaveFormat.DocX);
          os.close();
          long now = System.currentTimeMillis();
          System.out.println("Pdf 转  Word  共耗时：" + ((now - old) / 1000.0) + "秒");
      } catch (Exception e) {
          System.out.println("Pdf 转 Word 失败...");
          e.printStackTrace();
      }
  }

  //转ppt
  public static void pdf2ppt(String pdfPath) {
      long old = System.currentTimeMillis();
      try {
          String wordPath=pdfPath.substring(0,pdfPath.lastIndexOf("."))+".ppt";
          FileOutputStream os = new FileOutputStream(wordPath);
          Document doc = new Document(pdfPath);
          doc.save(os, SaveFormat.Pptx);
          os.close();
          long now = System.currentTimeMillis();
          System.out.println("Pdf 转  PPT  共耗时：" + ((now - old) / 1000.0) + "秒");
      } catch (Exception e) {
          System.out.println("Pdf 转 PPT 失败...");
          e.printStackTrace();
      }
  }

  //转excel
  public static void pdf2excel(String pdfPath) {
      long old = System.currentTimeMillis();
      try {
          String wordPath=pdfPath.substring(0,pdfPath.lastIndexOf("."))+".xlsx";
          FileOutputStream os = new FileOutputStream(wordPath);
          Document doc = new Document(pdfPath);
          doc.save(os, SaveFormat. Excel );
          os.close();
          long now = System.currentTimeMillis();
          System.out.println("Pdf 转 EXCEL 共耗时：" + ((now - old) / 1000.0) + "秒");
      } catch (Exception e) {
          System.out.println("Pdf 转 EXCEL 失败...");
          e.printStackTrace();
      }
  }

  //转html
  public static void pdf2Html(String pdfPath) {
      long old = System.currentTimeMillis();
      try {
          String htmlPath=pdfPath.substring(0,pdfPath.lastIndexOf("."))+".html";
          Document doc = new Document(pdfPath);
          doc.save(htmlPath,SaveFormat.Html);
          long now = System.currentTimeMillis();
          System.out.println("Pdf 转  HTML  共耗时：" + ((now - old) / 1000.0) + "秒");
      } catch (Exception e) {
          System.out.println("Pdf 转 HTML 失败...");
          e.printStackTrace();
      }
  }

  //转图片
  public static void pdf2image(String pdfPath) {
      long old = System.currentTimeMillis();
      try {
          Resolution resolution = new Resolution(300);
          String dataDir=pdfPath.substring(0,pdfPath.lastIndexOf("."));
          File imageDir = new File(dataDir+"_images");
          imageDir.mkdirs();
          Document doc = new Document(pdfPath);
          PngDevice pngDevice = new PngDevice(resolution);
          for (int pageCount = 1; pageCount <= doc.getPages().size(); pageCount++) {
              OutputStream imageStream = new FileOutputStream(imageDir+"/"+pageCount+".png");
              pngDevice.process(doc.getPages().get_Item(pageCount), imageStream);
              imageStream.close();
          }
          long now = System.currentTimeMillis();
          System.out.println("Pdf 转  PNG  共耗时：" + ((now - old) / 1000.0) + "秒");
      } catch (Exception e) {
          System.out.println("Pdf 转 PNG 失败...");
          e.printStackTrace();
      }
  }


}

运行方法，idea里右键运行，如果要做成web系统可以将代码封装程web服务，调用方法就行。

转换文件结果

以一个十四的pdf文件转化为例，大部分转换时间在10-12s，只有转ppt花费的时间久一点需要20s.可能pdf里面不是表格类的内容，所以转换excel文件后，样式差别会有点大，其他文件转换后样式和之前是保持一样的。
