servlet url 映射中的问题？

Question

    @PostMapping(path = "/images")  
    
    public void sendFiles( @RequestParam("transferFile")MultipartFile transferFile, @RequestParam("id") int id,  HttpServletRequest request,HttpServletResponse response) {
        response.setContentType("application/images");
        try {
            String requestUrl="http://localhost:9090/NewFileHandling/file";
            URL url = new URL(requestUrl);
            HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
            httpCon.setDoOutput(true);
            
            

            OutputStream outputStream = httpCon.getOutputStream();
            byte[] data = transferFile.getBytes();
            
            outputStream.write(data);
            
            

        }catch (Exception e) {
            e.printStackTrace();
            System.err.println(e);
            
        }    
    
    }

**在 web.xml 中我给了 DispatcherServlet **

错误是没有映射 POST /SpringProject/images Kinldy 帮助。 提前致谢

我认为您还没有完成控制器级别的映射。

@Controller
@RequestMapping("/file")
