idea 项目 创建Dao对象时编译报错

Question

@Autowired
private RealNameAppleDao realNameAppleDao;

加上这两句话编译就报错
package com.newlife.service.impl;

import com.newlife.dao.RealNameAppleDao;
import com.newlife.model.RealNameApple;
import com.newlife.service.RealNameAppleService;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.multipart.MultipartFile;

/**
