代碼使用以下：

@Autowired
    private DocumentConverter documentConverter;

    public void toPdf(@PathVariable String fileName, HttpServletResponse response)
            throws IOException, OfficeException {
        ClassPathResource classPathResource = new ClassPathResource("static/aa.docx");
        InputStream inputStream = classPathResource.getInputStream();//獲取文件流
        response.reset();
        response.setContentType("multipart/form-data");
        fileName = new String(fileName.getBytes("gb2312"), "ISO8859-1");
        response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\".pdf");
        try (OutputStream outputStream = response.getOutputStream()) {
            documentConverter
                    .convert(inputStream).as(documentConverter.getFormatRegistry().getFormatByExtension("docx"))
                    .to(outputStream).as(documentConverter.getFormatRegistry().getFormatByExtension("pdf"))
                    .execute();
        }
    }
