第二部分，Session的关闭： 到了这里，我们就到了验证的最后一部分了，JbpmContext的关闭了。


【位置JbpmContext】

?
上述Junit?类继承的父类BaseTestCase是AbstractDependencyInjectionSpringContextTests的子类，
?启用了与OpenSessionInView一样的数据LazyLoading和JDBC Connection延迟关闭策略。

附件是测试这个这个流程所发生的Log，首先是SessionFactoryUtils打开了Hibernate Session，最后是SessionFactoryUtils关闭了Hibernate Session，符合Jbpm声称的Context哲学。
