Spring事务管理的两种方式

http://www.iteye.com/topic/1123347 http://blog.csdn.net/lcj8/article/details/2835432[/code] 
PS：好像还是tx标签的方式较为简单

tx标签设置拦截器：

<?xml version="1.0" encoding="UTF-8"?>
<beans  xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"> 
<context:component-scan base-package="com.springsession.demo" />
<context:property-placeholder location="classpath:jdbc.properties" />

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />

</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!--
<property name="mapperLocations" value="classpath*:com/springMyBatis/system.mapper/*.xml" />
-->
<property name="configLocation" value="classpath:mybatis-config.xml" />
</bean>

<bean id="testDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface" value="com.springsession.demo.dao.ISpringDao" />
<property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>

<bean id="serviceProxy" class="com.springsession.demo.service.TestService" autowire="byName" />

<!-- 事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>

<!-- 使用tx标签配置的拦截器 -->
<!-- 定义事务 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="*" propagation="REQUIRED" />
</tx:attributes>
</tx:advice>

<!-- 定义切面 -->
<aop:config>
<aop:pointcut id="interceptorPointcut" expression="execution(* com.springsession.demo.dao.*.*(..))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="interceptorPointcut" />
</aop:config>

</beans>


以代理的方式实现事务控制：

<?xml version="1.0" encoding="UTF-8"?>
<beans  xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 
<context:component-scan base-package="com.springsession.demo" />
<context:property-placeholder location="classpath:jdbc.properties" />

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />

</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!--
<property name="mapperLocations" value="classpath*:com/springMyBatis/system.mapper/*.xml" />
-->
<property name="configLocation" value="classpath:mybatis-config.xml" />
</bean>

<bean id="testDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface" value="com.springsession.demo.dao.ISpringDao" />
<property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>

<!-- 事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>

<!-- 定义事务 -->
<bean id="transactionProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"
lazy-init="true" abstract="true">
<property name="transactionManager" ref="transactionManager" />
<property name="transactionAttributes">
<props>
<!-- 拦截被代理类所有的方法  -->
<prop key="*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>

<!-- 配置代理对象，利用AOP进行拦截实现对事务的控制 -->
<bean id="serviceProxy" parent="transactionProxy">
<property name="target">
<bean class="com.springsession.demo.service.TestService" autowire="byName" />
</property>
</bean>

</beans>
