Hibernate lazy的异常的解决
org.hibernate.LazyInitializationException: could not initialize proxy - the owning Session was closed
在<many-to-one>里，设置成lazy="false".
或则<hibernate-mapping>
<class lazy="false">
或则在web.xml中加：
<filter>
<filter-name>openSessionInViewFilter </filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>openSessionInViewFilter </filter-name>
<url-pattern>*.do </url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>openSessionInViewFilter </filter-name>
<url-pattern>*.jsp </url-pattern>
</filter-mapping>
