• 支持Idea在java包下加载xml文件,防止报错

Mybatis配置文件

文件名：mybatis-config.xml

• 配置Mybatis配置文件(也可以在Spring中配置)

<configuration>

    <typeAliases>
        <package name="com.example.pojo"/>
    typeAliases>

Spring配置文件

• Spring配置文件

其中sqlSession可以不配

整合配置文件，用于管理Mapper中的类（mybatis-config.xml）

• 配置sqlSession

文件名：mybatis-config.xml：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd">

    <import resource="spring-config.xml"/>




    <bean id="userMapper" class="com.example.mapper.UserMapperImpl">
        <property name="sqlSession" ref="sqlSession"/>
    bean>
beans>

userMapperImpl(通过sqlSessionTemplate来操作)

public class UserMapperImpl implements UserMapper {

    //所有操作通过sqlSessionTemplate来操作
    private SqlSessionTemplate sqlSession;

    public void setSqlSession(SqlSessionTemplate sqlSession) {
        this.sqlSession = sqlSession;
    }

    public List<User> queryUser() {
        UserMapper mapper = sqlSession.getMapper(UserMapper.class);
        List<User> users = mapper.queryUser();
        return users;
    }
}

• 不配置sqlSession

文件名：mybatis-config.xml：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd">

    <import resource="spring-config.xml"/>

    <bean id="userMapper" class="com.example.mapper.UserMapperImpl">
        <property name="sqlSessionFactory" ref="sqlSessionFactory"/>
    bean>



beans>

userMapperImpl(通过sqlSessionFactory来操作，继承SqlSessionDaoSupport类,getSqlSession()获得sqlSession对象)

public class UserMapperImpl extends SqlSessionDaoSupport implements UserMapper {
    public List<User> queryUser() {
    	//获取Mapper的接口
        UserMapper mapper = getSqlSession().getMapper(UserMapper.class);
        //从Mybatis的Mapper.xml中查询数据
        List<User> users = mapper.queryUser();
        return users;
    }
}
