1) Scenario: Generally appears in multi-table queries.

1) Reason: Hibernate query, the bottom is through the call session in the method to achieve, but the session is used will be closed, then the call will appear no session exception

2) Workaround: Let the session delay close, and so on after the action is completed and then close, concrete method: Configure the filter in Web. XML to implement session delay shutdown. (and must be before the STRUTS2 Core configuration filter)
