WORD转PDF 字体问题

项目中有需求需要导出PDF，

市面上现在有很多word导出PDF，比如常用的两款 docx4j 和 aspose-words

docx4j 是开源的 aspose-words是商用的需要购买License 但是网上有破解的可以搜索到

docx4j

maven依赖

<dependency>
    <groupId>org.docx4j</groupId>
    <artifactId>docx4j-export-fo</artifactId>
    <version>8.3.8</version>
</dependency>
<dependency>
    <groupId>org.docx4j</groupId>
    <artifactId>docx4j-JAXB-ReferenceImpl</artifactId>
    <version>8.3.8</version>
</dependency>

特别说明：需要的是 *.ttf 格式的字体库如果缺失会出现乱码小方格。
1，word 导出pdf

    public void outPDF2(ByteArrayOutputStream outputStream, HttpServletResponse response, String fileName) throws Exception {
        ByteArrayInputStream inputStream = new ByteArrayInputStream(outputStream.toByteArray());
        WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(inputStream);
        ExcelUtils.exportPdf(response, fileName);
        setFontMapper(wordMLPackage);
        Docx4J.toPDF(wordMLPackage, response.getOutputStream());
        IOUtils.closeQuietly(inputStream);
        IOUtils.closeQuietly(response.getOutputStream());
    }

2, 引入需要的字体

private static void setFontMapper(WordprocessingMLPackage mlPackage) throws Exception {
        Mapper fontMapper = new IdentityPlusMapper();

        //引入系统的
        fontMapper.put("隶书", PhysicalFonts.get("LiSu"));
        fontMapper.put("宋体", PhysicalFonts.get("SimSun"));
        fontMapper.put("等线", PhysicalFonts.get("SimSun"));
        fontMapper.put("等线 Light", PhysicalFonts.get("SimSun"));
        fontMapper.put("仿宋_GB2312", PhysicalFonts.get("FangSong_GB2312"));
        fontMapper.put("新細明體", PhysicalFonts.get("SimSun"));
        //解决宋体（正文）和宋体（标题）的乱码问题
        PhysicalFonts.put("PMingLiU", PhysicalFonts.get("SimSun"));

        // 如果系统 自己下载的字体 引入
        PhysicalFonts.addPhysicalFonts("Microsoft Yahei", new ClassPathResource("font/Microsoft YaHei.ttf").getURI());
        fontMapper.put("Microsoft Yahei", PhysicalFonts.get("Microsoft YaHei.ttf"));
        mlPackage.setFontMapper(fontMapper);
    }

3，问题

如果word当中有表格表格中的单元格如果是英文和数字不会换行中文会自动换行这是一个BUG。

aspose-words
maven依赖

<dependency>
    <groupId>com.aspose</groupId>
    <artifactId>aspose-words</artifactId>
    <version>15.8.0</version>
</dependency>

特别说明：需要的是 *.ttc 格式的字体库如果缺失会出现乱码小方格。

1，word 导出pdf

    public void outPDF(ByteArrayOutputStream outputStream, HttpServletResponse response, String fileName) throws Exception {
        ByteArrayInputStream inputStream = new ByteArrayInputStream(outputStream.toByteArray());
        ExcelUtils.exportPdf(response, fileName);
        //引入字体所在的目录
        FontSettings.setFontsFolder("/tmp/fonts", true);
        //使用字体设置配置加载选项
        LoadOptions loadOptions = new LoadOptions();
        Document doc = new Document(inputStream, loadOptions);
        PdfSaveOptions options = new PdfSaveOptions();
        options.setCompliance(PdfCompliance.PDF_15);
        // 将Word转换为PDF
        doc.save(response.getOutputStream(), options);
        IOUtils.closeQuietly(inputStream);
        IOUtils.closeQuietly(response.getOutputStream());
    }

2，引入需要的字体

    static {
//        //执行字体
        Process process = null;
        try {
            //正常写 linux命令即可 、比如：mkdir xx/touch b.txt/sh start.sh/sh stop.sh

            String commend = "mkdir -p /tmp/fonts";
            process = Runtime.getRuntime().exec(commend);
            log.info("创建目录" + process.waitFor());

            log.info("拷贝字体");
            FileCopyUtils.copy(new ClassPathResource("font/Microsoft YaHei.ttc").getInputStream(), new FileOutputStream("/tmp/fonts/Microsoft YaHei.ttc"));

            commend = "chmod -R 777 /tmp/fonts";
            process = Runtime.getRuntime().exec(commend);
            log.info("授予权限" + process.waitFor());
//            setFontsSources();
        } catch (Exception e) {
            log.error("设置字体失败", e);
        }
    }

3，问题

aspose-words 是商用的需要自己在网上找下 license.xml 。
