java - MultipartFile 到 PDF 转换并下载此文件

Question

friend 们，我的代码有一个问题

我想将 MultipartFile 转换为 pdf 并将其下载到特定位置，任何人都可以帮助我

@RequestMapping(value = "/uploadFile", method = RequestMethod.PUT, consumes = { "multipart/form-data" })
public Map<String, String> uploadFile(@RequestParam("uploadfile") MultipartFile pdfFile) throws Exception {

    String url = pdfFile + "FileName";
    File fileToSave = new File(url);
    fileToSave.createNewFile();

    FileOutputStream fos = new FileOutputStream(fileToSave);
    fos.write(pdfFile.getBytes());
    fos.close();

    return null;
}

请尝试这个功能:

   public static File convert(MultipartFile file) throws IOException {
    File convFile = new File(file.getOriginalFilename());
    convFile.createNewFile();
    FileOutputStream fos = new FileOutputStream(convFile);
    fos.write(file.getBytes());
    fos.close();
    return convFile;
    }
