package com.test.dao.impl;

import com.test.dao.IItemsDao;
import com.test.mapper.ItemsMapper;
import com.test.pojo.Items;

import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.io.InputStream;
import java.util.List;

@Component
public class ItemsDao implements IItemsDao {

    @Autowired
    private SqlSessionFactory sqlSessionFactory;

    public ItemsDao()
    {

    }

    public List<items> selectItems()
    {
        SqlSession sqlSession= sqlSessionFactory.openSession();

        ItemsMapper itemsMapper= sqlSession.getMapper(ItemsMapper.class);

        List<items> itemsList= itemsMapper.selectItems();

        return itemsList;
    }
}

</items></items>

在build标签中添加

 <resources>
 <resource>
   <!-- 将Mapper的映射文件拷贝出来 -->
   <directory>src/main/java</directory>
   <includes>
   <include>**/*.xml</include>
   </includes>
   <filtering>true</filtering>
 </resource>
 </resources>

@Test
public void fun()
{
    ClassPathXmlApplicationContext classPathXmlApplicationContext=new ClassPathXmlApplicationContext("/applicationContext-ioc.xml");

    IItemsService itemsService= classPathXmlApplicationContext.getBean("itemsService",IItemsService.class);

     System.out.println(itemsService.selectItems());
}

​ 1.在applicationContext-ioc.xml文件中 添加

<!-- 配置映射文件的扫描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.test.mapper">
</property></bean>

   @Autowired
   private IItemsDao itemsDao;

修改为

   @Autowired
   private ItemsMapper itemsMapper;

​ 完整代码如下

import com.test.pojo.Items;

    public List<items> selectItems()
    {

    }
}
