Spring三种事务处理方式
</bean>
<!--数据源-->
<bean id="datasource" value="${jdbc.driverclassname}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
<!--spring jdbc模板bean，它注入了上面的数据源-->
<bean id="jdbctemplate" ref="datasource"/>
</bean>
</bean>
</beans>
</bean>
<!--业务类bean-->
<bean id="userserviceimpltarget" ref="userjdbcdao"/>
</bean>
<property name="target" ref="userserviceimpltarget"/><!--指定业务bean-->
<property name="transactionattributes"><!--事务的属性设置列表-->
<props>
<prop key="add*">propagation_required,isolation_serializable</prop>
<!--设置事务为只读时，添加数据将会产生异常-->
<!--<prop key="add*">propagation_required,isolation_serializable,readonly</prop>-->
</props>
