Java word 转换为pdf

JAVA 中 word转pdf的方式主要有：

1.    Use Apache POI & iText (代码较多, 且转换格式不够完美).
2.   jacob + msOfficeWord + SaveAsPDFandXPS （完美保持原doc格式，效率最慢，只能在windows环境下进行）
3.  Aspose.Words  (完美保持原doc格式,使用简单，收费. 破解包下载)

本文使用第一张和第三种方式

一. Aspose.Words 为收费版，要想转换完成的去掉水印，需要付费或个人使用破解版

@Test
public  void doc2PDF() {
    String docPath ="D:/2222.docx";
    String pdfPath="D:/aspose.pdf";
    try {
        File file = new File(pdfPath);
        FileOutputStream os = new FileOutputStream(file);
        com.aspose.words.Document doc = new com.aspose.words.Document(docPath);
        doc.save(os, SaveFormat.PDF);//全面支持DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF, EPUB, XPS, SWF 相互转换
    } catch (Exception e) {
        e.printStackTrace();
    }
}

 二. Apache POI & iText

      所需jar包，----->maven 依赖

    String inputFile="D:/test3.docx";
    String outputFile="D:/convert.pdf";
    System.out.println("inputFile:" + inputFile + ",outputFile:"+ outputFile);
    FileInputStream in=new FileInputStream(inputFile);
    XWPFDocument document=new XWPFDocument(in);
    File outFile=new File(outputFile);
    OutputStream out=new FileOutputStream(outFile);
    PdfOptions options=null;
