pdf转word可编辑 百分百还原文件
1.下载三方jar包
下载jar包的地址
2.代码破解水印和页数限制
1.引入依赖
<!--jar破解工具-->
<dependency>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.20.0-GA</version>
</dependency>2.去除限制
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;
public class Test2 {
private static void crack(String jarName) throws Exception {
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")) {
// 去除水印处理
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<>();
// 删除这两个文件
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);
InputStream 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();
}
// 测试
public static void main(String[] args) throws Exception {
// 下载jar包的路径
// String jarPath = "D:\\maven\\maven-Repository\\com\\aspose\\aspose-pdf\\21.8\\aspose-pdf-21.8.jar";
String jarPath = "C:\\Users\\lenovo\\Downloads\\aspose-pdf-22.9-jdk17.jar";
// 调用方法
crack(jarPath);
}
}破解成功输出：
3. 将破解的包放入lib中并在pom中配置依赖
<dependency>
<groupId>com.aspose</groupId>
<artifactId>aspose-pdf</artifactId>
<version>22.10</version>
<scope>system</scope>
<!--jar存放的路径 -->
<systemPath>${project.basedir}/src/main/resources/lib/aspose-pdf-22.10-jdk16.jar</systemPath>
</dependency>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<includeSystemScope>true</includeSystemScope>
</configuration>
</plugin>
4.在resource下创建一个static包，然后创建一个license.xml文件
<?xml version="1.0" encoding="UTF-8" ?>
<License>
<Data>
<Products>
<Product>Aspose.Total for Java</Product>
<Product>Aspose.Words for Java</Product>
</Products>
<EditionType>Enterprise</EditionType>
<SubscriptionExpiry>20991231</SubscriptionExpiry>
<LicenseExpiry>20991231</LicenseExpiry>
<SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber>
</Data>
<Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</Signature>
</License>
5.实现PDF转换word功能
import cn.hutool.core.io.resource.ClassPathResource;
import cn.hutool.core.io.resource.Resource;
import com.aspose.pdf.Document;
import com.aspose.pdf.License;
import java.io.FileOutputStream;
import java.io.InputStream;
public class Test3 {
// 获取license.xml的文件
public static boolean getLicense() {
boolean result = false;
Resource resource = new ClassPathResource("static/license.xml");
try (InputStream is = resource.getStream()) {
License aposeLic = new License();
aposeLic.setLicense(is);
result = true;
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
/**
* PDF转Word操作
*
* @param sourceFile 源文件
* @param targetFile 目标文件
*/
public static boolean pdf2doc(String sourceFile, String targetFile) {
if (!getLicense()) {
System.out.println("license获取失败");
return false;
}
try {
long old = System.currentTimeMillis();
FileOutputStream os = new FileOutputStream(targetFile);
Document doc = new Document(sourceFile);//加载源文件数据
doc.save(os, com.aspose.pdf.SaveFormat.DocX);//设置转换文件类型并转换
os.close();
long now = System.currentTimeMillis();
System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒"); //转化用时
} catch (Exception e) {
e.printStackTrace();
}
return true;
}
// 将原来的包替换成破解以后的包将不会出现水印和页数限制
public static void main(String[] args) throws Exception {
String sourceFile = "D:\\test\\test1.pdf";
// 生成的路径
String targetFile = "D:\\test\\test2.docx";
// 调用方法
pdf2doc(sourceFile, targetFile);
}
}这也是我在工作中发现的一个好东西，确实好用所以记录一下。
