    import com.sun.jersey.api.client.Client;
    import com.sun.jersey.api.client.WebResource;
    import org.springframework.stereotype.Controller;

    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.ResponseBody;
    import org.springframework.web.multipart.MultipartFile;
    
    import javax.servlet.http.HttpServletRequest;
    import java.util.UUID;
    
    @Controller
    public class HelloController {
        @RequestMapping(value = "/upload", method = RequestMethod.POST)
        @ResponseBody
        public Object uploadFiles(@RequestParam("fileName") MultipartFile[] multipartFile,
                                  HttpServletRequest httpServletRequest, String name) {
            System.out.println(name);
            try {
                String path = "http://localhost:9090/static/";
                // 生成文件在服务器端存放的名字
                for (int i = 0; i < multipartFile.length; i++) {
                    String fileSuffix = multipartFile[i].getOriginalFilename()
                            .substring(multipartFile[i].getOriginalFilename().lastIndexOf("."));
                    String fileName = UUID.randomUUID().toString() + fileSuffix;
                    // 上传
                    Client client = Client.create();
                    WebResource resource = client.resource(path + fileName);
                    resource.put(multipartFile[i].getBytes());
                }
            } catch (Exception e) {
                e.printStackTrace();
                return "fail";
            }
            return "success";
        }
    }
