Arch-05-15-[spring+ibatis+postgresql]事务配置问题

当插入数据后，接着执行一条查询语句，不能查询到这条记录，加了事务后，反而报 25P02 错，查了许久，才明白是 spring 配置 的事务处理有误。

原配如下：

=================

	<bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
		<property name="transactionManager" ref="TransactionManager" />
		<property name="transactionAttributes">
			<props>
				<prop key="create*">
					PROPAGATION_REQUIRED,-Exception
				</prop>
				<prop key="*WithNewTranscation">PROPAGATION_REQUIRES_NEW</prop>
				<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
				<prop key="delete*">PROPAGATION_REQUIRED</prop>
				<prop key="clear*">PROPAGATION_REQUIRED</prop>
				<prop key="update*">PROPAGATION_REQUIRED</prop>
				<prop key="set*">PROPAGATION_REQUIRED</prop>
				<prop key="insert*">PROPAGATION_REQUIRED</prop>
				<prop key="create*">PROPAGATION_REQUIRED</prop>
				<prop key="load*">PROPAGATION_REQUIRED</prop>
				<prop key="do*">PROPAGATION_REQUIRED</prop>
				<prop key="push*">PROPAGATION_REQUIRED</prop>
				<prop key="change*">PROPAGATION_REQUIRED</prop>
				<prop key="rank*">PROPAGATION_REQUIRED</prop>
				<prop key="*">PROPAGATION_REQUIRED,readOnly</prop>
			</props>
		</property>
	</bean>
	<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
		<property name="beanNames">
			<value>*Service</value>
		</property>
		<property name="interceptorNames">
			<list>
				<value>transactionInterceptor</value>
				<!-- 
				<value>logAfterAdvice</value>
				 -->
			</list>
		</property>
	</bean>	

后来修改的配置如下

	<bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
		<property name="transactionManager" ref="TransactionManager" />
		<property name="transactionAttributes">
			<props>
				<prop key="create*">
					PROPAGATION_REQUIRED,-Exception
				</prop>
				<prop key="*WithNewTranscation">PROPAGATION_REQUIRES_NEW</prop>
				<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
				<prop key="delete*">PROPAGATION_REQUIRED</prop>
				<prop key="clear*">PROPAGATION_REQUIRED</prop>
				<prop key="update*">PROPAGATION_REQUIRED</prop>
				<prop key="set*">PROPAGATION_REQUIRED</prop>
				<prop key="insert*">PROPAGATION_REQUIRED</prop>
				<prop key="create*">PROPAGATION_REQUIRED</prop>
				<prop key="load*">PROPAGATION_REQUIRED</prop>
				<prop key="do*">PROPAGATION_NOT_SUPPORTED,-Exception</prop>
				<prop key="push*">PROPAGATION_REQUIRED</prop>
				<prop key="change*">PROPAGATION_REQUIRED</prop>
				<prop key="rank*">PROPAGATION_REQUIRED</prop>
				<prop key="*">PROPAGATION_REQUIRED,readOnly</prop>
				<prop key="unique*">
					PROPAGATION_NOT_SUPPORTED
				</prop>
			</props>
		</property>
	</bean>
	<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
		<property name="beanNames">
			<value>*Service,*Dao</value>
		</property>
		<property name="interceptorNames">
			<list>
				<value>transactionInterceptor</value>
			</list>
		</property>
	</bean>	

修改执行插入的方法，将方法名称前加上 unique 变成 uniqueInsert... 就可以了。
