摘要：如何用java实现word文档转pdf呢

最近在网上看了很多资料，遇到了很多头疼的问题，看了各类大神写的方法，最初想要研究的是在线预览word

现在来看，不太现实，除了微软研究的一套在线预览的url，但是满足的条件有点扯淡，有兴趣的可以去查资料

还有就是各类各样的收费平台，来看看这种转换的处理方法吧

    public static void main(String[] args) {
        doc2pdf("/Users/lzl/Desktop/a.docx","/Users/lzl/Desktop/test.pdf");
    public static void doc2pdf(String inPath, String outPath) {
        FileOutputStream os =null;
        try {
            File file = new File(outPath); // 新建一个空白pdf文档
            os = new FileOutputStream(file);
            Document doc = new Document(inPath); // Address是将要被转化的word文档
            //insertWatermarkText(doc, "四叶草的诗雨");
            doc.save(os, SaveFormat.PDF);
        } catch (Exception e) {
            e.printStackTrace();
        }finally{
            if(os!=null){
                try {
                    os.close();
                } catch (IOException e) {
                    e.printStackTrace();
　　加水印（升级版）
private static void insertWatermarkText(Document doc, String watermarkText) throws Exception
        Shape watermark = new Shape(doc, ShapeType.TEXT_PLAIN_TEXT);
        //水印内容
        watermark.getTextPath().setText(watermarkText);
        //水印字体
        watermark.getTextPath().setFontFamily("宋体");
        //水印宽度
        watermark.setWidth(500);
        //水印高度
        watermark.setHeight(100);
        //旋转水印
        watermark.setRotation(-40);
        //水印颜色
        watermark.getFill().setColor(Color.lightGray);
        watermark.setStrokeColor(Color.lightGray);
        watermark.setRelativeHorizontalPosition(RelativeHorizontalPosition.PAGE);
        watermark.setRelativeVerticalPosition(RelativeVerticalPosition.PAGE);
        watermark.setWrapType(WrapType.NONE);
        watermark.setVerticalAlignment(VerticalAlignment.CENTER);
        watermark.setHorizontalAlignment(HorizontalAlignment.CENTER);
        Paragraph watermarkPara = new Paragraph(doc);
        watermarkPara.appendChild(watermark);
        for (Section sect : doc.getSections())
            insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_PRIMARY);
            insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_FIRST);
            insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_EVEN);
        System.out.println("Watermark Set");
    private static void insertWatermarkIntoHeader(Paragraph watermarkPara, Section sect, int headerType) throws Exception
        HeaderFooter header = sect.getHeadersFooters().getByHeaderFooterType(headerType);
        if (header == null)
            header = new HeaderFooter(sect.getDocument(), headerType);
            sect.getHeadersFooters().add(header);
        header.appendChild(watermarkPara.deepClone(true));
