在ssh开发中,往往有这样的配置在spring 中的配置文件中
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource">
<ref local="dataSource" />
</property>
</bean>
<bean id="transactionAttributeSource"
class="org.springframework.transaction.interceptor.NameMatchTransactionAttributeSource">
<property name="properties">
<props> <prop key="query*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
<bean id="transactionInterceptor"
class="org.springframework.transaction.interceptor.TransactionInterceptor">
<property name="transactionManager">
<ref bean="transactionManager" />
</property>
<property name="transactionAttributeSource">
<ref bean="transactionAttributeSource" />
</property>
</bean>谁帮我解释下这3个bean的关系哦,谢谢
