我正在使用Spring MVC,这是我的方法:

/**
* Upload single file using Spring Controller.
*/
@RequestMapping(value = "/uploadFile", method = RequestMethod.POST)
public @ResponseBody ResponseEntity<GenericResponseVO<? extends IServiceVO>> uploadFileHandler(
            @RequestParam("name") String name,
            @RequestParam("file") MultipartFile file,
            HttpServletRequest request,
            HttpServletResponse response) {

    if (!file.isEmpty()) {
        try {
            byte[] bytes = file.getBytes();

            // Creating the directory to store file
            String rootPath = System.getProperty("catalina.home");
            File dir = new File(rootPath + File.separator + "tmpFiles");
            if (!dir.exists()) {
                dir.mkdirs();
            }

            // Create the file on server
            File serverFile = new File(dir.getAbsolutePath() + File.separator + name);
            BufferedOutputStream stream = new BufferedOutputStream(new FileOutputStream(serverFile));
            stream.write(bytes);
            stream.close();

            System.out.println("Server File Location=" + serverFile.getAbsolutePath());

            return null;
        } catch (Exception e) {
            return null;
        }
    }
}

我需要在邮递员和文件中传递会话id。我该怎么做呢?

如果您想发出PUT请求,只需将所有事情都作为POST请求进行,但将_method => PUT添加到您的form-data参数中。

在弹簧架侧使用以下代码:

@PostMapping(value = Constant.API_INITIAL + "/uploadFile")
    public UploadFileResponse uploadFile(@RequestParam("file") MultipartFile file,String jsonFileVo) {
        FileUploadVo fileUploadVo = null;
        try {
            fileUploadVo = new ObjectMapper().readValue(jsonFileVo, FileUploadVo.class);
        } catch (Exception e) {
            e.printStackTrace();
        }

Body > binary >选择文件

首先,设置post in方法和填充链接API

然后选择Body -> form-data ->输入你的参数名(根据你的代码文件)

如果有人需要:

Body -> form-data

将字段名添加为数组

您可以同时发送Image和可选/必选参数。

在postman中,有Params标签。
