springCloud異常：下游服務通過Gateway網關過濾以後拿不到HttpServletRequest

下游服務controller:

public class BaseController { 
protected String sessionId = null; 
protected void getSessionIdFromRequest(HttpServletRequest request) {
 this.sessionId = request.getHeader().get("Session-Id");
 }
}

報錯信息：

No primary or default constructor found for interface javax.servlet.http.HttpServletReques

緣由：Gateway中不支持HttpServletRequest，換成ServerHttpRequest便可！！！
