关于xml配置：

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="packagesToScan">
<list>
<value>com.program.**.domain</value>
</list>
</property>
<property name="hibernateProperties">
            <props>
            <prop key="hibernate.dialect">
            org.hibernate.dialect.MySQLDialect
            </prop>
            <prop key="hibernate.show_sql">true</prop>     
            <prop key="hibernate.current_session_context_class">thread</prop>
            </props>
        </property>

</bean> 

其中以下内容一定要有：

<prop key="hibernate.current_session_context_class">thread</prop>
