这几天搞spring的事务，试过了几种方式，现在归纳一下，前面两种都是xml格式的，后面一种是AspectJ的
1、最基本的，基于bean定义的方式，这种方式就是通过BeanNameAutoProxyCreator和拦截器来实现，比较适用于旧版本的Spring
<beans>
<!– Transaction manager for a single Hibernate SessionFactory (alternative to JTA) –>
<bean id=”transactionManager” class=”org.springframework.orm.hibernate3.HibernateTransactionManager”>
<property name=”sessionFactory”>
<ref bean=”sessionFactory”/>
</property>
</bean>
<bean id=”transactionInterceptor” class=”org.springframework.transaction.interceptor.TransactionInterceptor”>
<property name=”transactionManager” ref=”transactionManager”/>?
<property name=”transactionAttributes”>
<props>
<prop key=”*”>PROPAGATION_REQUIRED</prop>
<prop key=”find*”>PROPAGATION_REQUIRED,readOnly</prop>
</props>
</property>
</bean>
<bean class=”org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator”>
<property name=”beanNames”>
<value>*Service,*Manager</value>
</property>
<property name=”interceptorNames”>
<list>
<value>transactionInterceptor</value>
<!– 此处增加新的Interceptor –>
</list>
</property>
</bean>
<bean class=”org.springframework.transaction.interceptor.TransactionAttributeSourceAdvisor”>
<property name=”transactionInterceptor” ref=”transactionInterceptor”/>?
</bean>
<bean id=”userManager” class=”some.package.UserManagerImpl” autoWire=”byName”/>
</beans>
2、这种方式是基于xml的aop设置，这种方式就是基于aop的xml配置，有切入点和通知，好处是不用在下面的Bean里面用AspectJ
<?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:aop=”http://www.springframework.org/schema/aop”
xmlns:tx=”http://www.springframework.org/schema/tx”
xsi:schemaLocation=”
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd”>
<bean id=”testPropertyConfigurer” class=”org.springframework.beans.factory.config.PropertyPlaceholderConfigurer” scope=”singleton”>
<property name=”location”>
<value>classpath:service.properties</value>
</property>
</bean>
<bean id=”testDataSource” class=”com.mchange.v2.c3p0.ComboPooledDataSource” scope=”singleton”>
<property name=”driverClass” value=”com.mysql.jdbc.Driver”></property>
<property name=”jdbcUrl” value=”${jdbc.url}”></property>
<property name=”user” value=”${jdbc.user}”></property>
<property name=”password” value=”${jdbc.password}”></property>
<property name=”autoCommitOnClose” value=”false”/>
<property name=”initialPoolSize” value=”3″/>
<property name=”minPoolSize” value=”3″/>
<property name=”maxPoolSize” value=”10″/>
<property name=”maxIdleTime” value=”7200″/>
<property name=”acquireIncrement” value=”3″/>
<property name=”checkoutTimeout” value=”15000″/>
<property name=”maxIdleTimeExcessConnections” value=”3600″/>
</bean>
<bean id=”txManager” class=”org.springframework.jdbc.datasource.DataSourceTransactionManager”>
<property name=”dataSource” ref=”testDataSource”/>
</bean>
<tx:advice id=”txAdvice” transaction-manager=”txManager”>
<tx:attributes>
<tx:method name=”get*” read-only=”true” />
<tx:method name=”*” propagation=”REQUIRED” />
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut id=”testOperation” expression=”execution(* com.test.ooxx.BeanB.*(..))”/>
<aop:advisor advice-ref=”txAdvice” pointcut-ref=”testOperation”/>
</aop:config>
<bean id=”Bean_A” class=”com.test.ooxx.BeanA” scope=”singleton”>
<property name=”dataSource” ref=”testDataSource”></property>
</bean>
<bean id=”Bean_B” class=”com.test.ooxx.BeanB” scope=”prototype”>
<property name=”a” ref=”Bean_A”></property>
</bean>
</beans>
3、最后这种就是AspectJ的定义
<?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:aop=”http://www.springframework.org/schema/aop”
xmlns:tx=”http://www.springframework.org/schema/tx”
xsi:schemaLocation=”
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd”>
<bean id=”testPropertyConfigurer” class=”org.springframework.beans.factory.config.PropertyPlaceholderConfigurer” scope=”singleton”>
<property name=”location”>
<value>classpath:service.properties</value>
</property>
</bean>
<bean id=”testDataSource” class=”com.mchange.v2.c3p0.ComboPooledDataSource” scope=”singleton”>
<property name=”driverClass” value=”com.mysql.jdbc.Driver”></property>
<property name=”jdbcUrl” value=”${jdbc.url}”></property>
<property name=”user” value=”${jdbc.user}”></property>
<property name=”password” value=”${jdbc.password}”></property>
<property name=”autoCommitOnClose” value=”false”/>
<property name=”initialPoolSize” value=”3″/>
<property name=”minPoolSize” value=”3″/>
<property name=”maxPoolSize” value=”10″/>
<property name=”maxIdleTime” value=”7200″/>
<property name=”acquireIncrement” value=”3″/>
<property name=”checkoutTimeout” value=”15000″/>
<property name=”maxIdleTimeExcessConnections” value=”3600″/>
</bean>
<bean id=”txManager” class=”org.springframework.jdbc.datasource.DataSourceTransactionManager”>
<property name=”dataSource” ref=”testDataSource”/>
</bean>
<tx:annotation-driven transaction-manager=”txManager”/>
<bean id=”Bean_A” class=”com.test.ooxx.BeanA” scope=”singleton”>
<property name=”dataSource” ref=”testDataSource”></property>
</bean>
<bean id=”Bean_B” class=”com.test.ooxx.BeanB” scope=”prototype”>
<property name=”a” ref=”Bean_A”></property>
</bean>
</beans>
这种方式在类方法里面要用AspectJ声明：
@Transactional(readOnly=false, propagation=Propagation.REQUIRED)
public boolean process() {…}
