Spring无法自动注入dubbo服务

Question

开发工具：idea java

使用框架：spring + springmvc + mybatis + dubbo

dubbo 是一个高性能、基于 java 的开源 RPC 框架。 当我使用spring@autowired时报错，如图图1。 但是我在java注解的时候，效果很好，如图图二。 Figure 1 Figure 2

代码1。服务的 spring/applicationContext-service.xml。

代码2。用于控制器的 spring/spring-mvc.xml。
代码3。服务 代码4。控制器（这里有个问题，用@autowired不能自动注入） 谢谢！

项目服务代码：

package xyz.maojun.service.impl;

import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import xyz.maojun.common.pojo.EasyUIDateGridResult;
import xyz.maojun.mapper.TbItemMapper;
import xyz.maojun.pojo.TbItem;
import xyz.maojun.pojo.TbItemExample;
import xyz.maojun.service.ItemService;

import javax.annotation.Resource;
import java.util.List;

@Service
public class ItemServiceImpl implements ItemService {
    @Autowired
    private TbItemMapper tbItemMapper;

    @Override
    public TbItem getItemById(long itemid) {

        TbItemExample example = new TbItemExample();
        TbItemExample.Criteria criteria = example.createCriteria();

        criteria.andIdEqualTo(itemid);

        List<TbItem> list = tbItemMapper.selectByExample(example);
        if (list != null && list.size() > 0) {
            return list.get(0);
        }
        return null;
    }
}

控制器：

  package xyz.maojun.controller;
 import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    import xyz.maojun.pojo.*;
    import xyz.maojun.service.ItemService;
    import javax.annotation.Resource;
    @Controller
    public class ItemController {
        @Resource  // i want to use @autowired ,but it not work
        private ItemService itemService;
        @RequestMapping("/item/{itemId}")
        @ResponseBody
        public TbItem getItemById(@PathVariable long itemId) {
            TbItem tbItem = itemService.getItemById(itemId);
            return tbItem;
        }
    }

我已经得到了这个答案，是Intellij IDEA的问题。运行项目时没有这个错误，我使用spring注解，Intellij IDEA会找不到bean然后报错。 Ignore false positives
