2种常见的spring事物处理方式

1.事务代理: 继承 TransactionProxyFactoryBean 

 

	<!-- 事务代理 -->
	<bean id="transactionProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"
		abstract="true">
		<property name="transactionManager">
			<ref bean="transactionManager" />
		</property>
		<property name="transactionAttributes">
			<props>
				<prop key="select*">PROPAGATION_REQUIRED,readOnly</prop>
				<prop key="*">PROPAGATION_REQUIRED</prop>
			</props>
		</property>
	</bean>

	<!-- TransactionManager定义。 -->
	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>

	<!-- MyBatis transactionTemplate -->
	<bean id="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate">
		<property name="transactionManager" ref="transactionManager" />
	</bean>

	<!-- MyBatis sqlSessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="configLocation" value="classpath:mybatis.xml" />
		<property name="mapperLocations">
			<list>
				<value>classpath:com/desk/user/core/dao/**/*Mapper.xml
				</value>
			</list>
		</property>
	</bean>

	<!-- MyBatis sqlSessionTemplate -->
	<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
		<constructor-arg ref="sqlSessionFactory" />
	</bean>

 

业务处理bean 注入方式

	<bean id="userService" parent="transactionProxy">
		<property name="target">
			<bean class="com.desk.user.core.service.user.UserServiceImpl" />
		</property>
	</bean>

 

2.事物代理:BeanNameAutoProxyCreator beanName 代理

 

	<!--事务拦截器 -->
	<bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
		<property name="transactionManager" ref="transactionManager" />
		<property name="transactionAttributes">
			<props>
				<prop key="select">PROPAGATION_REQUIRED,readOnly</prop>
				<prop key="*">PROPAGATION_REQUIRED</prop>
			</props>
		</property>
	</bean>
	<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
		<property name="proxyTargetClass">
			<value>true</value>
		</property>
		<property name="beanNames">
			<list>
				<value>*ServiceImpl</value>
			</list>
		</property>
		<property name="interceptorNames">
			<list>
				<value>transactionInterceptor</value>
			</list>
		</property>
	</bean>

	<!--异常和超时拦截器 -->
	<bean id="exceptionHandler" class="com.desk.common.handler.ExceptionHandler" />
	<bean id="timeHandler" class="com.desk.common.handler.TimeHandler" />
	<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
		<property name="proxyTargetClass">
			<value>true</value>
		</property>
		<property name="beanNames">
			<list>
				<!-- <value>*Render</value> <value>*Controller</value> <value>*BOImpl</value> -->
				<value>*ServiceImpl</value>
				<value>*DAOImpl</value>
			</list>
		</property>
		<property name="interceptorNames">
			<list>
				<value>exceptionHandler</value>
				<value>timeHandler</value>
			</list>
		</property>
	</bean>

	<!-- TransactionManager定义。 -->
	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>

	<!-- MyBatis transactionTemplate -->
	<bean id="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate">
		<property name="transactionManager" ref="transactionManager" />
	</bean>

	<!-- MyBatis sqlSessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="configLocation" value="classpath:mybatis.xml" />
		<property name="mapperLocations">
			<list>
				<value>classpath:com/desksoft/oceanus/user/core/dao/**/*Mapper.xml
				</value>
			</list>
		</property>
	</bean>

	<!-- MyBatis sqlSessionTemplate -->
	<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
		<constructor-arg ref="sqlSessionFactory" />
	</bean>

 业务处理bean注入

	<!-- service 注入 -->
	<bean id="userService" class="com.desksoft.oceanus.user.core.service.user.UserServiceImpl" />
