1. Lazy Loading

Because of the load lazy loading mechanism at this time, the session is closed when the JSP page sends the SQL statement. So I will report the above mistakes. You can add a filter so that the session closes after the request response is complete.

The filter is to be configured in front of the struts2 filter. The filters are configured as follows:

    <filter>        <filter-name>OpenSessionInViewFilter</filter-name>        <filter-class >org.springframework.orm.hibernate4.support.opensessioninviewfilter</filter-class>    </filter>    <filter-mapping>        <filter-name> opensessioninviewfilter </filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>

2, if the problem has not been resolved. It's a package conflict. Hibernate and Strus both have javassist-xx.jar this package only needs to be imported one on it, remove one of them.
