Spring

Spring配置事务主要有这2种方式。 
1、配置一个Spring提供的一个工厂类，然后将需要进行事务管理的bean放入工厂bean中进行委托代理。 

<bean id="companyDAOProxy"    class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
    <property name="transactionManager">
        <ref bean="transactionManager" />
    </property>
    <property name="target">
        <ref local="companyDAOTarget" />
    </property>
    <property name="transactionAttributes">
        <props>
        <prop key="insert*">PROPAGATION_REQUIRED</prop>
        <prop key="delete*">PROPAGATION_REQUIRED</prop>
        <prop key="find*">
        PROPAGATION_REQUIRED,readOnly
        </prop>
        </props>
    </property>
</bean>
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource">
<ref local="dataSource" />
</property>
</bean>

2、采用AOP方式进行事务配置,注意在配置文件中要注明AOP schema的地址。 

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource">
<ref local="dataSource" />
</property>
</bean>
<aop:config>
<aop:pointcut id="serviceMethods" expression="execution(* com.business.impl..*Service*.*(..))" />
<aop:advisor pointcut-ref="serviceMethods" advice-ref="txAdvice" />
</aop:config>
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="get*"    propagation="SUPPORTS" read-only="true" />
<tx:method name="load*"   propagation="SUPPORTS" read-only="true" />
</tx:attributes>
</tx:advice>
