Zuul 如何在pre Filter內(nèi)為request setAttribute

我希望能在zuul的filter對request進行setAttribute("key",value)操作，然后在下游的服務(wù)能夠通過request.getAttribute("key")的方式獲取到數(shù)據(jù)；但結(jié)果未如預(yù)期發(fā)生，在filter內(nèi)為request添加了attribute并未被傳遞到下游服務(wù)中；

        }else{

        }
        return IS_FILTER;
    }

    //超級管理員角色

        request.setAttribute(RequestAttributeKeyEnum.ACCOUNT_ADMIN.getKey(),admin);

        RequestContext.getCurrentContext().setRequest(request);
    }
}

這是我的自定義pre filter 對request進行操作發(fā)生在最后的addRequestAttribute方法內(nèi)，應(yīng)該如何操作讓下游接收到我在filter內(nèi)對request添加的數(shù)據(jù)；
