小结一下OpenSessionInView

感谢javaeye差沙和cac的回复.

OpenSessionInView默认的FlushMode为

FlushMode.NEVER 
可以采用在写保存更新删除代码的时候手动更改FlushMode

        this.getHibernateTemplate().execute(new HibernateCallback() { 
            public Object doInHibernate(Session session) throws HibernateException { 
                session.setFlushMode(FlushMode.AUTO); 
                session.save(user); 
                session.flush(); 
                return null; 
            } 
        }); 

但是这样做太繁琐了,第二种方式是采用spring的事务声明

    <bean id="baseTransaction" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" 
          abstract="true"> 
        <property name="transactionManager" ref="transactionManager"/> 
        <property name="proxyTargetClass" value="true"/> 
        <property name="transactionAttributes"> 
            <props> 
                <prop key="get*">PROPAGATION_REQUIRED,readOnly</prop> 
                <prop key="find*">PROPAGATION_REQUIRED,readOnly</prop> 
                <prop key="load*">PROPAGATION_REQUIRED,readOnly</prop> 
                <prop key="save*">PROPAGATION_REQUIRED</prop> 
                <prop key="add*">PROPAGATION_REQUIRED</prop> 
                <prop key="update*">PROPAGATION_REQUIRED</prop> 
                <prop key="remove*">PROPAGATION_REQUIRED</prop> 
            </props> 
        </property> 
    </bean> 

    <bean id="userService" parent="baseTransaction"> 
        <property name="target"> 
            <bean class="com.phopesoft.security.service.impl.UserServiceImpl"/> 
        </property> 
    </bean>
