Java实现PDF转Word
原文链接：https://blog.csdn.net/Mgg9702/article/details/124987483
1、引入jar包或依赖
这里用到的是aspose-pdf，这个依赖需要单独配置仓库地址，也可以直接去官网下载jar包

不会配置仓库地址的话可以去官网下载jar包，官网链接
下面是百度网盘地址里面有未破解和已破解的jar包自行选择下载

2、破解
找到你的jar包地址，引入依赖的去maven仓库地址找到jar，将地址填入代码中的jarPath，运行Main方法会在jar包统计目录下生成破解的包
aspose-pdf-22.4.cracked.jar,替换掉原来jar包就可以了
public class PDFJarCrack {
public static void main(String[] args) throws Exception {
String jarPath = "jar包地址";
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();
}

3、pdf转word
填入你的pdf地址运行Main方法即可转换为word文档
public class Pdf2Word {
public static void main(String[] args) throws IOException {
pdf2doc("pdf地址");
}
//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();
}
}
