Hibernate Lazy loading without Servlet Filter

[Gideon]

Hi,

I must use the lazy loading feature from Hibernate 3 within my client application.

I use the Spring's AOP TransactionInterceptor as described in chapter 11.2.6 at Spring Docs.

at the spring api docs I read that lazy loading only works with a open session, but how can I use this feature without the OpenSessionIviewFilter ??

thanks.

You can use the OpenSessionInViewInterceptor. http://static.springframework.org/sp...terceptor.html

It will wrap your normal beans with a hibernate session.

Hi,

thank you for your hint.

but it does not work for me, this is my configuration:

	<bean id="myHibernateInterceptor" class="org.springframework.orm.hibernate3.HibernateInterceptor">
		<property name="sessionFactory"><ref bean="sessionFactory"/></property>
		<property name="entityInterceptorBeanName"><value>sessionInterceptor</value></property>
    </bean> 


	<!-- Hibernate SessionFactory -->
	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<!-- property name="jtaTransactionManager"><ref bean="transactionManager"/></property-->
		<property name="dataSource"><ref local="dataSource"/></property>		
		<property name="mappingResources">
			<list>
				<value>de.mk.user.hbm.xml</value>
				<value>de.mk.srb.model.hbm.xml</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">$&#123;hibernate.dialect&#125;</prop>
				<prop key="hibernate.show_sql">true</prop>
			</props>
		</property>
	</bean>
	
	<bean name="sessionInterceptor" class="org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor">
		<property name="sessionFactory"><ref bean="sessionFactory"/></property>
	</bean>

has anyone any idee what I have maked wrong?

thanks.

You must wrap your business beans with the interceptor. It is not enough to actually declare it:

<bean name="myUrl.htm" class="org.springframework.aop.framework.ProxyFact oryBean">
<property name="proxyInterfaces">
<value>org.springframework.web.servlet.mvc.Control ler</value>
</property>
<property name="interceptorNames">
<list>
<value>transactionInterceptor</value>
<value>myActualController</value>
</list>
</property>
</bean>

your example is for a webapplication but, I need lazy fetching without WebContent.

is there a way to use this Interceptor inside a client application (yes the application runs inside tomcat but the beans they need lazy fetching are jobs that where fired by quartz) ?

thanks.
