freemarker填充ftl格式转PDF三页问题 documents4j 实现Word文档、xlsx、等格式转换PDF文件

导入依赖：

        implementation 'com.documents4j:documents4j-local:1.0.3'
        implementation 'com.documents4j:documents4j-transformer-msoffice-word:1.0.3' //word
        implementation 'com.documents4j:documents4j-transformer-msoffice-excel:1.0.3' //excel

实现方式：

  public void exportFilePdf(
      Map<String, Object> data, String name, String fileName, HttpServletResponse response)
      throws TemplateException, IOException {
    Configuration configuration = new Configuration(Configuration.getVersion());
    configuration.setClassForTemplateLoading(this.getClass(), "/templates");
    Template template = configuration.getTemplate(name);
    String content = FreeMarkerTemplateUtils.processTemplateIntoString(template, data);

    InputStream inputStream = IOUtils.toInputStream(content);
    int index;
    byte[] bytes = new byte[1024];
    FileOutputStream downloadFile = new FileOutputStream("D:\\data\\a.docx");
    while ((index = inputStream.read(bytes)) != -1) {
      downloadFile.write(bytes, 0, index);
      downloadFile.flush();
    }
    downloadFile.close();
    inputStream.close();

    File inputWord = new File("D:\\data\\a.docx");
//    File outputFile = new File("D:\\data\\a.pdf");
    try {
      InputStream docxInputStream = new FileInputStream(inputWord);
//      OutputStream outputStream = new FileOutputStream(outputFile);
      IConverter converter = LocalConverter.builder().build();
      ServletOutputStream outputStream = response.getOutputStream();
      converter.convert(docxInputStream).as(DocumentType.DOCX).to(outputStream).as(DocumentType.PDF).execute();
      docxInputStream.close();
      outputStream.close();
      inputWord.delete();
      System.out.println("pdf转换成功");
    } catch (Exception e) {
      e.printStackTrace();
    }
  }




  public void exportFileExcel(
          Map<String, Object> data, String name, String fileName, HttpServletResponse response)
          throws TemplateException, IOException {
    Configuration configuration = new Configuration(Configuration.getVersion());
    configuration.setClassForTemplateLoading(this.getClass(), "/templates");
    Template template = configuration.getTemplate(name);
    String content = FreeMarkerTemplateUtils.processTemplateIntoString(template, data);
    InputStream inputStream = IOUtils.toInputStream(content);
    int index;
    byte[] bytes = new byte[1024];
    FileOutputStream downloadFile = new FileOutputStream("D:\\data\\a.docx");
    while ((index = inputStream.read(bytes)) != -1) {
      downloadFile.write(bytes, 0, index);
      downloadFile.flush();
    }
    downloadFile.close();
    inputStream.close();

    File inputWord = new File("D:\\data\\1.xlsx");
//    File outputFile = new File("D:\\data\\a.pdf");
    try {
      InputStream docxInputStream = new FileInputStream(inputWord);
//      OutputStream outputStream = new FileOutputStream(outputFile);
      IConverter converter = LocalConverter.builder().build();
      ServletOutputStream outputStream = response.getOutputStream();
      converter.convert(docxInputStream).as(DocumentType.XLSX).to(outputStream).as(DocumentType.PDF).execute();
      docxInputStream.close();
      outputStream.close();
      inputWord.delete();
      System.out.println("pdf转换成功");
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
