SSM框架做项目的时候一直注入失败，注解也写了，扫描路径也没错都已经困扰了两天了求大神解答一下

[问道于途]

这是我的错误提示：

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customerServiceImpl': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.company.item.dao.CustomerMapper] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

这是我的要注入的实现类

import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;

import com.company.item.dao.CustomerMapper;
import com.company.item.model.Customer;
import com.company.item.service.CustomerService;
import com.framework.utils.PrimaryKeyUtil;
@Service

public class CustomerServiceImpl implements CustomerService {
@Resource
private CustomerMapper customerMapper;
public boolean addCustomer(Customer customer) {
customer.setCustomerId(PrimaryKeyUtil.getPrimaryKey());
int i=customerMapper.insertSelective(customer);
return i>0?true:false;
}

}

这是我的扫描路径

这是我Dao层的配置

<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:mybatisConfiguration.xml" />
<!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 -->

</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
