Hibernate and spring integration appear hibernate. Hibernateexception:createcriteria is not valid without active transaction

When Hibernate and spring are consolidated, the following is commented out in the contents of the Hibernate.cfg.xml file specified in spring:

<!--Enable Hibernate ' s automatic session context management--
<!--<property name= "Current_session_context_class" >thread</property>-
In this way, the Hibernate session can be administered to spring, and spring can be used to manage the methods in DAO using the slice method.

Comment out <property name= "Current_session_context_class" in the configuration file >thread</property> post-resolution
