HibernateTemplate.save()与HibernateTemplate.update() 无法写入数据库的问题

解决办法有两种：

1. 将<prop key="hibernate.connection.autocommit">true</prop>设置为true即可解决，实现事务自动提交

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
	<property name="hibernateProperties">
		<props>
			<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
			<prop key="hibernate.show_sql">true</prop>
			<prop key="hibernate.connection.autocommit">true</prop>
		</props>
	</property>
	<property name="configLocation" value="/WEB-INF/hibernate.cfg.xml"></property>
</bean>

2.使用Spring的事务管理

<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
	<property name="sessionFactory" ref="sessionFactory" />
</bean>

<aop:config>
	<aop:pointcut expression="execution(public * service.*.*(..))" id="bussinessService" />
	<aop:advisor pointcut-ref="bussinessService" advice-ref="txAdvice" />
</aop:config>

<tx:advice id="txAdvice" transaction-manager="txManager">
	<tx:attributes>
		<tx:method name="exists" read-only="true" />
		<tx:method name="add*" propagation="REQUIRED" />
	</tx:attributes>
</tx:advice>
