</dependency>

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

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


<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>

<tx:method name="find" isolation="DEFAULT" propagation="SUPPORTS" read-only="true"/>

<tx:method name="" isolation="DEFAULT" propagation="REQUIRED"/>
