配置文件:





	<!-- 1. 数据源 : DriverManagerDataSource -->

	<context:component-scan base-package="com.springmvc.dao" />  

	<bean id="datasource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

		<property name="driverClassName" value="com.mysql.jdbc.Driver"/>

		<property name="url" value="jdbc:mysql://localhost:3306/mybaitis"/>

		<property name="username" value="root"/>

		<property name="password" value="root"/>

	</bean>

	

	<!-- 

		2. mybatis的SqlSession的工厂: SqlSessionFactoryBean 

			dataSource / typeAliasesPackage

	-->

	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

		<property name="dataSource" ref="datasource"/>

		<property name="typeAliasesPackage" value="com.springmvc.mybaitsmodel"/>

	</bean>



	<bean id="session" class="org.mybatis.spring.SqlSessionTemplate">

		<constructor-arg index="0" ref="sqlSessionFactory" />

		<!-- <constructor-arg index="1" value="BATCH" />如果想要进行批量操作可加入这个属性 -->

	</bean>

	<!-- 

		3. mybatis自动扫描加载Sql映射文件 : MapperScannerConfigurer 

			sqlSessionFactory / basePackage

	-->

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

		<property name="basePackage" value="com.springmvc.mybaitsmodel"/>

		<property name="sqlSessionFactory" ref="sqlSessionFactory"/>

	</bean>

	

	<!-- 4. 事务管理 : DataSourceTransactionManager -->

	<bean id="manager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

		<property name="dataSource" ref="datasource"/>

	</bean>



	<!-- 5. 使用声明式事务 -->

	<tx:annotation-driven transaction-manager="manager" />

DAO：





public class UserDaoImpl implements UserDao {

	@Autowired 

	private SqlSession session;

	

	public SqlSession getSession() {

		return session;

	}



	public void setSession(SqlSession session) {

		System.out.println("runing......");

		this.session = session;

	}

.....

......后面执行的
