关于Spring的OpenSessionInViewFilter的Hibernate会话25

<class name="com.cmmi.bcm.data.BcmGood" table="bcm_good" schema="dbo" lazy="true">
这个表有N个外表关联，然后再web.xml中加上了过滤，成功的在web展示页面中显示每个BcmGood的数据，但是我加了WorkHibernateFilter过滤以后，其他（单表业务）模块的根本不能做相应业务处理（saveorupdate，del），望大家多多指教，qq：289450605 一直在线。

	<filter>
		<filter-name>WorkHibernateFilter</filter-name>
		<filter-class>com.***.fiter.IDEHibernateFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>WorkHibernateFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

IDEHibernateFilter.java

public class IDEHibernateFilter extends OpenSessionInViewFilter
{
 protected Session getSession(SessionFactory sessionFactory)
            throws DataAccessResourceFailureException
    {
        Session session = SessionFactoryUtils.getSession(sessionFactory, true);
        session.setFlushMode(FlushMode.AUTO);
        return session;
    }
}

问题补充：
<bean id="icurrencyService"
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager">
<ref local="transactionManager" />
</property>
<property name="target">
<ref local="currencyServiceimpl" />
</property>
<property name="transactionAttributes">
<props>
<prop key="save*">PROPAGATION_REQUIRED</prop>
<prop key="update*">PROPAGATION_REQUIRED</prop>
<prop key="delete*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
问题补充：
在没有加OpenSessionInViewFilter过滤的时候，单表业务成功操作，显示相应结果。然后BcmGood是一张一对多表，用列表显示时报session close，然后加上OpenSessionInViewFilter过滤,其它（一对一）表的业务像del和saveorupdate，业务无法操作成功。这个执行过程中，无异常抛出。

OpenSessionInViewFilter作用就是在调用你写的代码前绑定session,只要保证它早于你的Action执行就可以了,
给你个参考的配置：
