java - RestTemplate 调用，其中函数的参数是 MultipartHttpServletRequest 请求

Question

您好，我必须进行 Resttemplate 调用才能对以下函数进行调用，其中参数是 MultiPartHttpServletRequest 请求、HttpServletRequest requestForm、HttpServletResponse 响应

Map<String, String> upload(MultipartHttpServletRequest request,
                                       HttpServletRequest requestForm, HttpServletResponse response, @RequestParam("name") String name,
                                       @RequestParam("id") String id,
                                       @RequestParam(value = "contanctno", required = false, defaultValue = Constants.DIGITS) String contactNo,
                                       @RequestParam(value = "address", required = false,) String address) throws InvalidReqException

除此之外，问题是我有要发送的文件，但如何发送该特定文件以及名称 version.pdf，其中版本总是变化。有人可以帮助我吗

请求方法=POST

假设您要将新文件以新名称保存在硬盘上，您可以添加 MultipartFile 作为参数，并将文件内容从上传的文件复制到硬盘上的新文件中。磁盘:

Map<String, String> upload(MultipartHttpServletRequest request,
    HttpServletRequest requestForm, HttpServletResponse response, @RequestParam("name") String name,
    @RequestParam("id") String id,
    @RequestParam(value = "contanctno", required = false, defaultValue = Constants.DIGITS) String contactNo,
    @RequestParam(value = "address", required = false) String address,
    @RequestParam("file") MultipartFile file) throws InvalidReqException {

    String newFileName = "newFileName.pdf";
    File newPdf = new File(newFileName);
    Files.copy(file.getInputStream(), newPdf.toPath());
