Spring框架中使用注解实现事务

<!-- 配置事物管理器 txManager-->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="oracle.jdbc.OracleDriver" ></property>
        <property name="url" value="127.0.0.1:1521:ORCL"></property>
        <property name="username" value="scott"></property>
        <property name="password" value="tiger"></property>
    
    </bean>
    <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    
    
    <!--增加对事物的支持  -->
    <tx:annotation-driven transaction-manager="txManager"/>
