Java PDF转Word
洛阳泰山 人气:0一、前言
学习概述:简单的介绍一下本篇文章要讲解的Java知识点
学习目标:读者读完这篇文章之后,你希望他掌握你讲解的哪些重要的知识点
二、jar破解
1.项目远程仓库配置
aspose-pdf 这个需要配置单独的仓库地址才能下载,不会配置的可以去官网直接下载jar引入项目代码中。
<repositories> <repository> <id>AsposeJavaAPI</id> <name>Aspose Java API</name> <url>https://repository.aspose.com/repo/</url> </repository> </repositories>
2.pom文件引入相关依赖
<dependency> <groupId>org.javassist</groupId> <artifactId>javassist</artifactId> <version>3.20.0-GA</version> </dependency> <!-- https://mvnrepository.com/artifact/com.aspose/aspose-pdf --> <dependency> <groupId>com.aspose</groupId> <artifactId>aspose-pdf</artifactId> <version>21.8</version> </dependency>
Javassist是一个开源的分析、编辑和创建Java字节码的类库。
aspose-pdf是一个处理pdf的java类库。
3.破解代码
import javassist.*; import java.io.*; import java.util.ArrayList; import java.util.Enumeration; import java.util.List; import java.util.jar.JarEntry; import java.util.jar.JarFile; import java.util.jar.JarOutputStream; /** * @date 2022-05-16 * @user tarzan */ public class PDFJarCrack { public static void main(String[] args) throws Exception { String jarPath = "E:\\maven_repository\\com\\aspose\\aspose-pdf\\21.8\\aspose-pdf-21.8.jar"; crack(jarPath); } private static void crack(String jarName) { try { ClassPool.getDefault().insertClassPath(jarName); CtClass ctClass = ClassPool.getDefault().getCtClass("com.aspose.pdf.ADocument"); CtMethod[] declaredMethods = ctClass.getDeclaredMethods(); int num = 0; for (int i = 0; i < declaredMethods.length; i++) { if (num == 2) { break; } CtMethod method = declaredMethods[i]; CtClass[] ps = method.getParameterTypes(); if (ps.length == 2 && method.getName().equals("lI") && ps[0].getName().equals("com.aspose.pdf.ADocument") && ps[1].getName().equals("int")) { // 最多只能转换4页 处理 System.out.println(method.getReturnType()); System.out.println(ps[1].getName()); method.setBody("{return false;}"); num = 1; } if (ps.length == 0 && method.getName().equals("lt")) { // 水印处理 method.setBody("{return true;}"); num = 2; } } File file=new File(jarName); ctClass.writeFile(file.getParent()); disposeJar(jarName, file.getParent()+"/com/aspose/pdf/ADocument.class"); } catch(NotFoundException e){ e.printStackTrace(); } catch(CannotCompileException e){ e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } private static void disposeJar(String jarName, String replaceFile) { List<String> deletes = new ArrayList<>(); deletes.add("META-INF/37E3C32D.SF"); deletes.add("META-INF/37E3C32D.RSA"); File oriFile = new File(jarName); if (!oriFile.exists()) { System.out.println("######Not Find File:" + jarName); return; } //将文件名命名成备份文件 String bakJarName = jarName.substring(0, jarName.length() - 3) + "cracked.jar"; // File bakFile=new File(bakJarName); try { //创建文件(根据备份文件并删除部分) JarFile jarFile = new JarFile(jarName); JarOutputStream jos = new JarOutputStream(new FileOutputStream(bakJarName)); Enumeration entries = jarFile.entries(); while (entries.hasMoreElements()) { JarEntry entry = (JarEntry) entries.nextElement(); if (!deletes.contains(entry.getName())) { if(entry.getName().equals("com/aspose/pdf/ADocument.class")){ System.out.println("Replace:-------" +entry.getName()); JarEntry jarEntry = new JarEntry(entry.getName()); jos.putNextEntry(jarEntry); FileInputStream fin = new FileInputStream(replaceFile); byte[] bytes = readStream(fin); jos.write(bytes, 0, bytes.length); }else { jos.putNextEntry(entry); byte[] bytes = readStream(jarFile.getInputStream(entry)); jos.write(bytes, 0, bytes.length); } } else { System.out.println("Delete:-------" + entry.getName()); } } jos.flush(); jos.close(); jarFile.close(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } } private static byte[] readStream(InputStream inStream) throws Exception { ByteArrayOutputStream outSteam = new ByteArrayOutputStream(); byte[] buffer = new byte[1024]; int len = -1; while ((len = inStream.read(buffer)) != -1) { outSteam.write(buffer, 0, len); } outSteam.close(); inStream.close(); return outSteam.toByteArray(); }
修改你本机的aspose-pdf-21.8.jar路径,然后运行主方法,破解成功后,会再同级文件夹下生成一个aspose-pdf-21.8.cracked.jar包,用这个包替换原来的aspose-pdf-21.8.jar包即可。

三、pdf转word
代码实现
import com.aspose.pdf.Document; import com.aspose.pdf.SaveFormat; import java.io.*; public class PDFHelper3 { public static void main(String[] args) throws IOException { pdf2doc("C:\\Users\\liuya\\Desktop\\pdf\\中信重工铸锻公司数字化工厂技术要求.pdf"); } //pdf转doc public static void pdf2doc(String pdfPath) { long old = System.currentTimeMillis(); try { //新建一个word文档 String wordPath=pdfPath.substring(0,pdfPath.lastIndexOf("."))+".docx"; FileOutputStream os = new FileOutputStream(wordPath); //doc是将要被转化的word文档 Document doc = new Document(pdfPath); //全面支持DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF, EPUB, XPS, SWF 相互转换 doc.save(os, SaveFormat.DocX); os.close(); //转化用时 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(); } } }
修改自己的pdf文件路径,运行主方法即可,完成无水印,无页数限制转换word文件
