与spring结合

实体省略
maping文件省略
dao接口省略
mybatis配置文件

<context:property-placeholder location="classpath:mysql.properties" /> 
 
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

    <property name="url" value="${jdbc.url}" />

    <property name="dataSource" ref="dataSource" /> 
</bean> 
 
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 
    <property name="configLocation" value="classpath:mybatis-config.xml" /> 
    <property name="dataSource" ref="dataSource" /> 
</bean> 
 
<!— mapper bean --> 
<bean id="studentMapper" class="org.mybatis.spring.MapperFactoryBean"> 
    <property name="mapperInterface" value="com.manager.data.StudentMapper" /> 
    <property name="sqlSessionFactory" ref="sqlSessionFactory" /> 
</bean> 

studentMapper定义的是一个mapperfactorybean。
它需要一个借口，sqlsessionfactory。
会自动生成代理的dao实现

或者可以通过spring的扫描
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 
    <property name="annotationClass" value="org.springframework.stereotype.Repository"/> 
    <property name="basePackage" value="com.liming.manager"/> 
    <property name="sqlSessionFactory" ref="sqlSessionFactory"/> 
</bean>
