Spring管理Hibernate事务的4种方式

1、TransactionProxyFactoryBean

<?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:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="configLocation" value="classpath:hibernate.cfg.xml">
        </property>
    </bean>
    <bean id="TblUserDAO" class="com.angi.dao.TblUserDAO">
        <property name="sessionFactory">
            <ref bean="sessionFactory" />
        </property>
    </bean>
    <!-- 声明一个 Hibernate 3 的 事务管理器供代理类自动管理事务用 -->
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory">
            <ref local="sessionFactory" />
        </property>
    </bean>
    <bean id="TblUserDAOProxy"
        class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
        <!--
            注意这个属性, 详细意义请参考Spring文档中的CGLIB部分或者本章的 10.7.2参考资料部分, 必须为 true
            使用CGLIB才不用强制编写DAO接口
        -->
        <property name="proxyTargetClass">
            <value>true</value>
        </property>
        <property name="transactionManager">
            <ref bean="transactionManager" />
        </property>
        <property name="target">
            <ref local="TblUserDAO" />
        </property>
        <property name="transactionAttributes">
            <props>
                <!-- 这里的方法签名可以精确到方法, 先懒惰一下全配置上 -->
                <prop key="*">PROPAGATION_REQUIRED</prop>
            </props>
        </property>
    </bean>
</beans>

2、TransactionInterceptor

<?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:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="configLocation" value="classpath:hibernate.cfg.xml">
        </property>
    </bean>
    <bean id="tblUserDAO" class="com.angi.dao.TblUserDAO">
        <property name="sessionFactory">
            <ref bean="sessionFactory" />
        </property>
    </bean>
    <bean id="tblUserService" class="com.angi.dao.service.TblUserService">
        <property name="tblUserDAO">
            <ref bean="tblUserDAO" />
        </property>
    </bean>
    <!-- 声明一个 Hibernate 3 的 事务管理器供代理类自动管理事务用 -->
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory">
            <ref local="sessionFactory" />
        </property>
    </bean>
    <bean
        class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
        <property name="beanNames">
            <list>
                <value>tblUserService</value>
            </list>
        </property>
        <property name="interceptorNames">
            <list>
                <value>transactionInterceptor</value>
            </list>
        </property>
    </bean>
    <bean id="transactionInterceptor"
        class="org.springframework.transaction.interceptor.TransactionInterceptor">
        <property name="transactionManager" ref="transactionManager" />
        <property name="transactionAttributes">
            <props>
                <!-- 这里的方法签名可以精确到方法, 先懒惰一下全配置上 -->
                <prop key="*">PROPAGATION_REQUIRED</prop>
            </props>
        </property>
    </bean>
</beans>

3、AOP和TX配置

<?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:p="http://www.springframework.org/schema/p"
    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-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="configLocation" value="classpath:hibernate.cfg.xml">
        </property>
    </bean>
    <bean id="tblUserDAO" class="com.angi.dao.TblUserDAO">
        <property name="sessionFactory">
            <ref bean="sessionFactory" />
        </property>
    </bean>
    <bean id="tblUserService" class="com.angi.dao.service.TblUserService">
        <property name="tblUserDAO">
            <ref bean="tblUserDAO" />
        </property>
    </bean>
    <!-- 声明一个 Hibernate 3 的 事务管理器供代理类自动管理事务用 -->
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory">
            <ref local="sessionFactory" />
        </property>
    </bean>
    <!-- 需要引入aop的命名空间 -->
    <aop:config>
        <!-- 切入点指明了在执行Service的所有方法时产生事务拦截操作 -->
        <aop:pointcut id="daoMethods"
            expression="execution(* com.angi.dao.service.TblUserService.*(..))" />
        <!-- 定义了将采用何种拦截操作，这里引用到 txAdvice -->
        <aop:advisor advice-ref="txAdvice" pointcut-ref="daoMethods" />
    </aop:config>
    <!-- 需要引入tx的命名空间 -->
    <!-- 这是事务通知操作，使用的事务管理器引用自 transactionManager -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <!-- 指定哪些方法需要加入事务，这里懒惰一下全部加入，可以使用通配符来只加入需要的方法 -->
            <tx:method name="*" propagation="REQUIRED" />
        </tx:attributes>
    </tx:advice>
</beans>

4、anotation

<?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:p="http://www.springframework.org/schema/p"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">
    <!-- 需要引入tx的命名空间 -->
    <tx:annotation-driven transaction-manager="transactionManager" />
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="configLocation" value="classpath:hibernate.cfg.xml">
        </property>
    </bean>
    <bean id="tblUserDAO" class="com.angi.dao.TblUserDAO">
        <property name="sessionFactory">
            <ref bean="sessionFactory" />
        </property>
    </bean>
    <bean id="tblUserService" class="com.angi.dao.service.TblUserService">
        <property name="tblUserDAO">
            <ref bean="tblUserDAO" />
        </property>
    </bean>
    <!-- 声明一个 Hibernate3 的事务管理器供代理类自动管理事务用 -->
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory">
            <ref local="sessionFactory" />
        </property>
    </bean>
</beans>

 

@Transactional
    public void doTransaction() {
        // step1 insert
        TblUser tblUser1 = new TblUser();
        tblUser1.setId(24);
        tblUser1.setUsername("Angi12");
        tblUser1.setPassword("Wang21");
        tblUserDAO.save(tblUser1);
        // step2 update
        TblUser tblUser2 = tblUserDAO.findById(2);
        tblUser2.setPassword(tblUser2.getPassword() + "a");
        tblUserDAO.update(tblUser2);
        // step3 insert
        TblUser tblUser = new TblUser();
        tblUser.setId(23);
        tblUser.setUsername("Angi");
        tblUser.setPassword("Wang");
        tblUserDAO.save(tblUser);
    }
