Java使用aspose实现pdf转word

一、下载aspose-pdf-21.6.jar包【下载地址】，存放目录结构如图；配置pom.xml。

<!--pdf to word-->
<dependency><groupId>com.aspose</groupId><artifactId>aspose-pdf</artifactId><version>21.6</version><scope>system</scope><systemPath>${project.basedir}/src/main/resources/lib/aspose-pdf-21.6.jar</systemPath>
</dependency>

二、创建PDFHelper.java类。运行代码同目录会出现docx文件。

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("D://test.pdf");}/*** pdf转doc** @param pdfPath pdf 路径*/public static void pdf2doc(String pdfPath) {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} catch (Exception e) {System.out.println("Pdf 转 Word 失败...");e.printStackTrace();}}
}

注意：如果aspose-pdf-21.6.jar是官网下载，转换的文件有水印。需要用下面代码运行破解，从新生成aspose-pdf-21.6.jar包引用。从我上面链接下载已经破解了。
