SSH中的Spring事务代理的常用的两种方法

 

这个配置文件是我做SSH的时候用的片断，用Spring来管理事务：

<!-- spring代理hibernate事务的两种方法 -->
    
    <!-- 不管采用哪种方法　下面的这个bean都是必须的 -->
    
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory">
            <ref local="sessionFactory" />
        </property>
    </bean>
    
    <!-- 1、spring事务代理模板 -->
    
    <!-- 需要事务的Service类要继承下面的bean，使用方法如下-->
    
    <!-- 
    <bean id="txProxyTemplate" abstract="true"
                   class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
        <property name="transactionManager">
            <ref bean="transactionManager"/>
        </property>
        <property name="transactionAttributes">
            <props>
                <prop key="save*">PROPAGATION_REQUIRED</prop>
                <prop key="del*">PROPAGATION_REQUIRED</prop>
                <prop key="change*">PROPAGATION_REQUIRED</prop>
                <prop key="*">PROPAGATION_REQUIRED,readOnly</prop>
            </props>
        </property>
    </bean>
    
    <bean id="StudentDaoHibernate"
        class="com.lideedu.yame.dao.hibernate.StudentDAOHibernateImpl"
        singleton="false">
        <property name="sessionFactory">
            <ref bean="sessionFactory" />
        </property>
        <property name="classService">
            <ref bean="ClassService" />
        </property>
    </bean>
    
    <bean id="StudentServiceTarget"
        class="com.lideedu.yame.business.IStudentServiceImpl" singleton="false">
        <property name="studentDAO">
            <ref bean="StudentDaoHibernate" />
        </property>
    </bean>
    
    <bean id="StudentService" parent="txProxyTemplate">
        <property name="target">
            <ref bean="StudentServiceTarget"/>
        </property>
    </bean>
    
    -->    
        
    <!-- 2、spring事务自动代理 -->
    
    <!-- 需要事务的方法只要方法名和下面的模式匹配就可以接受Spring的事务代理 -->
    
    <bean id="autoProxy"
        class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator">
    </bean>
    <bean id="transactionAttributeSource"
        class="org.springframework.transaction.interceptor.NameMatchTransactionAttributeSource">
        <property name="properties">
            <props>
                <prop key="save*">PROPAGATION_REQUIRED</prop>
                <prop key="update*">PROPAGATION_REQUIRED</prop>            
                <prop key="del*">PROPAGATION_REQUIRED</prop>
                <prop key="change*">PROPAGATION_REQUIRED</prop>        
            </props>
        </property>
    </bean>
    <bean id="transactionInterceptor"
        class="org.springframework.transaction.interceptor.TransactionInterceptor">
        <property name="transactionManager">
            <ref bean="transactionManager" />
        </property>
        <property name="transactionAttributeSource">
            <ref bean="transactionAttributeSource" />
        </property>
    </bean>
    <bean id="transactionAdvisor"
        class="org.springframework.transaction.interceptor.TransactionAttributeSourceAdvisor">
        <constructor-arg>
            <ref bean="transactionInterceptor" />
        </constructor-arg>
    </bean>
