dubbo无法序列化HttpServletRequest问题

Question

dubbo接口中有这样一个方法public Map uploadIdImage(HttpServletRequest request)

启动项目调用该接口后报错

nested exception is com.alibaba.dubbo.rpc.RpcException: Failed to invoke remote method: uploadIdImage,
java.lang.IllegalStateException: Serialized class org.springframework.web.multipart.support.DefaultMultipartHttpServletRequest must implement java.io.Serializable

能看出来是无法反序列化的问题 ，如何能在接口实现类中得到HttpServletRequest 这个对象，正确调用方法。请教大虾，感激不尽

Answer 1

应该是要换一个参数，比如用HashMap,把request中需要用到的值存入map

public Map uploadIdImage(HashMap map)
