Aspose.Java实现word转pdf，添加水印等操作

Aspose是一款商用版控件，支持各类文档操作，这里主要介绍如何在Springboot项目中使用破解版。

一. word转pdf

1. 在项目中导入aspose.word包 百度网盘下载 提取码：pokb
2. 新建一个asposeUtil类，类中建立如下静态方法

    /**
     * @param wordPath 需要被转换的word全路径带文件名
     * @param pdfPath 转换之后pdf的全路径带文件名
     */
    public static void doc2pdf(String wordPath, String pdfPath) {
        if (!getLicense()) { // 验证License 若不验证则转化出的pdf文档会有水印产生
            return;
        }
        try {
            long old = System.currentTimeMillis();
            File file = new File(pdfPath); //新建一个pdf文档
            FileOutputStream os = new FileOutputStream(file);
            Document doc = new Document(wordPath); //Address是将要被转化的word文档
            doc.save(os, com.aspose.words.SaveFormat.PDF);
            long now = System.currentTimeMillis();
            os.close();
//            System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒"); //转化用时
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

3. 新建license.xml文件(放入Springboot项目的resources目录下)

<License>
    <Data>
        <Products>
            <Product>Aspose.Total for JavaProduct>
            <Product>Aspose.Words for JavaProduct>
        Products>
        <EditionType>EnterpriseEditionType>
        <SubscriptionExpiry>20991231SubscriptionExpiry>
        <LicenseExpiry>20991231LicenseExpiry>
        <SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7SerialNumber>
    Data>
    <Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=Signature>
License>

存放位置如图所示

4. 建立getLicense()方法

private static boolean getLicense() {
        boolean result = false;
        try {
            InputStream is = asposeUtil.class.getClassLoader().getResourceAsStream("license.xml"); // 如果是普通java项目(非Springboot项目)license.xml应放在..\WebRoot\WEB-INF\classes路径下
            System.out.println(is);
            License aposeLic = new License();
            aposeLic.setLicense(is);
//            com.aspose.cells.License cell = new com.aspose.cells.License();
//            cell.setLicense(is);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }

5. 之后我们直接通过asposeUtil.doc2pdf(wordPath, pdfPath)即可完成转换

二. 文档插入水印

插入水印的方法与上面大致相同，下面给出插入水印具体代码

 /**
     * 为word文档添加水印
     * @param doc word文档模型
     * @param watermarkText 需要添加的水印字段
     * @throws Exception
     */
    public 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(100);
        //水印高度
        watermark.setHeight(20);
        //旋转水印
        watermark.setRotation(-40);
        //水印颜色 浅灰色
        watermark.getFill().setColor(Color.lightGray);
        watermark.setStrokeColor(Color.lightGray);
        //设置相对水平位置
        watermark.setRelativeHorizontalPosition(RelativeHorizontalPosition.PAGE);
        //设置相对垂直位置
        watermark.setRelativeVerticalPosition(RelativeVerticalPosition.PAGE);
        //设置包装类型
        watermark.setWrapType(WrapType.NONE);
        //设置垂直对齐
        watermark.setVerticalAlignment(VerticalAlignment.CENTER);
        //设置文本水平对齐方式
        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");
    }
    /**
     * 在页眉中插入水印
     * @param watermarkPara
     * @param sect
     * @param headerType
     * @throws Exception
     */
    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));
    }

    /**
     * 设置水印属性
     * @param doc
     * @param wmText
     * @param left
     * @param top
     * @return
     * @throws Exception
     */
    public static Shape ShapeMore(Document doc, String wmText, double left, double top)throws Exception{
//        Shape waterShape = new Shape(doc, ShapeType.TEXT_PLAIN_TEXT);
        Shape waterShape = new Shape(doc, ShapeType.IMAGE);
        waterShape.getImageData().setImage(wmText);
        waterShape.setWidth(100.0);
        waterShape.setHeight(100.0);
        waterShape.setRotation(0);
        waterShape.setFilled(true);
//        //水印内容
//        waterShape.getTextPath().setText(wmText);
//        //水印字体
//        waterShape.getTextPath().setFontFamily("宋体");
//        //水印宽度
//        waterShape.setWidth(40);
//        //水印高度
//        waterShape.setHeight(13);
//        //旋转水印
//        waterShape.setRotation(-40);
        //水印颜色 浅灰色
        /*waterShape.getFill().setColor(Color.lightGray);
        waterShape.setStrokeColor(Color.lightGray);*/
        waterShape.setStrokeColor(new Color(210,210,210));
        //将水印放置在页面中心
        waterShape.setLeft(left);
        waterShape.setTop(top);
        //设置包装类型
        waterShape.setWrapType(WrapType.NONE);
        return waterShape;
    }

    /**
     * 插入多个水印
     * @param mdoc
     * @param wmText
     * @throws Exception
     */
    public static void WaterMarkMore(Document mdoc, String wmText)throws Exception{
        Paragraph watermarkPara = new Paragraph(mdoc);
//        for (int j = 0; j < 500; j = j + 100)
//        {
//            for (int i = 0; i < 700; i = i + 85)
//            {
//                Shape waterShape = ShapeMore(mdoc, wmText, j, i);
//                watermarkPara.appendChild(waterShape);
//            }
//        }
        Shape waterShape = ShapeMore(mdoc, wmText, 155, 300);
        watermarkPara.appendChild(waterShape);
        for (Section sect : mdoc.getSections())
        {
            insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_PRIMARY);
            insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_FIRST);
            insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_EVEN);
        }
    }
