dubbo服务中生产者我已经跑起来了，但在consumer中通过autowired方式注入bean失败，网上找了很久以下三点我确定已经做了
1.在实现类上加入@Service
2.在配置文件中加入scan扫描
下面代码我只要注释掉这个UserService的Autowired就能跑起来，感觉就是这个语句的问题，但是不注入UserService就无法调用getUserAddressList，感觉没搭成功，大神帮忙看看，困扰我好久了，谢谢啊

package com.atguigu.gmall.service.impl;

import com.atguigu.gmall.bean.UserAddress;
import com.atguigu.gmall.service.UserService;
import com.atguigu.gmall.service.OrderService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class OrderServiceImpl implements OrderService {

    @Autowired
    UserService userService;

    @Override
    public void initOrder(String id){
        //查询用户收货地址
        System.out.printf(id);
        List<UserAddress> addressList =  userService.getUserAddressList("1");
        System.out.println(addressList);
    }
}

消费者配置文件如下
