session被关闭有配置openSessionInViewFilter么？延迟关闭session。如下
<filter>
<filter-name>sessionFilter</filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
</filter-class>
<init-param>
<param-name>flushMode</param-name>
<param-value>AUTO</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>sessionFilter</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
