java - 在java中将docx转换为pdf时出错

Question

大家下午好，

就我的情况而言，我正在生成一个 docx 文档 Junction 2 其他 docx，我正在进行合并。

  public static void main(String[] args) throws Exception {
    InputStream in1 = new FileInputStream(new File("C:\\Clientes\\Constremac\\Repositorio_DOCS\\UPLOAD\\LAYOUT_PAGINA_VERSAO_FINAL.docx"));
    InputStream in2 = new FileInputStream(new File("C:\\Clientes\\Constremac\\Repositorio_DOCS\\UPLOAD\\modeloContratoSocial.docx"));
    OutputStream out = new FileOutputStream(new File("C:\\Clientes\\Constremac\\Repositorio_DOCS\\UPLOAD\\modeloContratoSocialMerge.docx"));
    mergeDocx(in1,in2,out);
}

 public static void mergeDocx(InputStream s1, InputStream s2, OutputStream os) throws Exception {
    WordprocessingMLPackage target = WordprocessingMLPackage.load(s1);
    insertDocx(target.getMainDocumentPart(), IOUtils.toByteArray(s2));
    SaveToZipFile saver = new SaveToZipFile(target);
    saver.save(os);
}
private static void insertDocx(MainDocumentPart main, byte[] bytes) throws Exception {
        AlternativeFormatInputPart afiPart = new AlternativeFormatInputPart(new PartName("/part" + (chunk++) + ".docx"));
        afiPart.setContentType(new ContentType(CONTENT_TYPE));
        afiPart.setBinaryData(bytes);
        Relationship altChunkRel = main.addTargetPart(afiPart);
        //convertAltChunks()
        CTAltChunk chunk = Context.getWmlObjectFactory().createCTAltChunk();
        chunk.setId(altChunkRel.getId());

        main.addObject(chunk);
}

我的最终文档(docx)没问题，可以正常打开。当我将此生成的文件转换为 PDF 时出现问题，出现以下错误:未实现:支持 w: altChunk -。

public boolean createPDF(String nomeArquivo)    {
    try     {
        long start = System.currentTimeMillis();
        Configuration confg = new Configuration();

        System.out.println(Configuration.repositorioUpload + nomeArquivo + ".docx");
        InputStream is = new FileInputStream(new File(Configuration.repositorioUpload + nomeArquivo + ".docx"));
        WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(is);

        PdfSettings pdfSettings = new PdfSettings();

        OutputStream out = new FileOutputStream(new File(Configuration.repositorioUpload + nomeArquivo + ".pdf"));
        PdfConversion converter = new Conversion(wordMLPackage);
        converter.output(out, pdfSettings);

        System.err.println("Generate " + Configuration.repositorioUpload  + nomeArquivo + ".pdf" + " with " + (
                System.currentTimeMillis() - start) + "ms");
    }
    catch (Throwable e) {
        e.printStackTrace();
    }
    return false;
}

我正在发送我使用的java代码，有一段时间我正在尝试生成这个pdf，如果有人能够帮助我，我将不胜感激。

谢谢大家。

拥抱!

我找到了一种使用 AltChunck 的方法，但甚至无法正确运行，导出到 PDF 时不会出现合并图像页脚和页眉。

public static void main(String[] args) throws Exception {

    boolean ADD_TO_HEADER = true;
    HeaderPart hp = null;

    String inputfilepath = "C:\\Clientes\\Constremac\\Repositorio_DOCS\\UPLOAD\\default_template.xml";

    String chunkPath = "C:\\Clientes\\Constremac\\Repositorio_DOCS\\UPLOAD\\sample.docx";

    boolean save = true;
    String outputfilepath =  "C:\\Clientes\\Constremac\\Repositorio_DOCS\\UPLOAD\\altChunk_out.docx";


    // Open a document from the file system
    // 1. Load the Package
    WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(new java.io.File(inputfilepath));
    //proce
    MainDocumentPart main = wordMLPackage.getMainDocumentPart();

    if (ADD_TO_HEADER) {
        hp = wordMLPackage.getDocumentModel().getSections().get(0).getHeaderFooterPolicy().getDefaultHeader();
    }

    AlternativeFormatInputPart afiPart = new AlternativeFormatInputPart(new PartName("/chunk.docx"));
    afiPart.setBinaryData(new FileInputStream(chunkPath));

    afiPart.setContentType(new ContentType("application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml")); //docx
    //afiPart.setContentType(new ContentType("application/xhtml+xml")); //xhtml

    Relationship altChunkRel = null;
    if (ADD_TO_HEADER) {
        altChunkRel = hp.addTargetPart(afiPart);
    } else {
        altChunkRel = main.addTargetPart(afiPart);          
    }

    CTAltChunk ac = Context.getWmlObjectFactory().createCTAltChunk();
    ac.setId(altChunkRel.getId());

    if (ADD_TO_HEADER) {
        hp.getJaxbElement().getEGBlockLevelElts().add(ac);
    } else {
        main.addObject(ac);
    }

    // Save it

    if (save) {     
        SaveToZipFile saver = new SaveToZipFile(wordMLPackage);
        saver.save(outputfilepath);
        System.out.println("Saved " + outputfilepath);
    }
}

我做错了什么？

altChunk 不是“真正的”docx 内容。

在以 PDF 格式输出之前，需要将其替换为普通的 WordML 段落、表格等。

您可以尝试自己执行此操作，如果内容不包含任何关系(图像、超链接等)或冲突的样式或编号，这很容易。请进一步查看http://www.docx4java.org/blog/2010/11/merging-word-documents/ ..或者我公司的网站plutext.com
