@Controller
@RequestMapping("/user")
public class UserConteoller {
 
 /**
  * 跨服务器文件上传
  * @return
  */
 @RequestMapping("/fileupload")
 public String fileupload(HttpServletRequest request, MultipartFile upload) throws Exception {
  System.out.println("文件上传");
 
  //定义上传文件服务器路径
  String path = "http://localhost:9090/uploads/";
 
  //获取上传文件的名称
  String filename = upload.getOriginalFilename();
  System.out.println(filename);
  //把文件的名称设置位置 uuid
  String uuid = UUID.randomUUID().toString().replace("-", "");
  System.out.println(uuid);
  filename = uuid + "_" + filename;
 
  //完成跨服务器上传
  //创建客户端对象
  Client client = Client.create();
  //和图片服务器进行连接
  WebResource webResource = client.resource(path + filename);
 
  //上传文件
  webResource.put(upload.getBytes());
  return "success";
 }
