本文详细介绍了在SSH2中的SessionFactory配置中如何正确设置hibernate.current_session_context_class属性以确保Spring能有效管理事务。文章指出，应将其设为org.springframework.orm.hibernate3.SpringSessionContext，并解释了这样做的原因及带来的好处。

在ssh2中的sessionFactory配置文件中应将hibernate.current_session_context_class设为org.springframework.orm.hibernate3.SpringSessionContext（默认为此值）并应用spring管理事务。
如果为<prop key="hibernate.current_session_context_class">thread</prop> 则会报异常，

在spring的类LocalSessionFactoryBean源码中
方法buildSessionFactory中

if (isExposeTransactionAwareSessionFactory()) {
				// Set Hibernate 3.1+ CurrentSessionContext implementation,
				// providing the Spring-managed Session as current Session.
				// Can be overridden by a custom value for the corresponding Hibernate property.
				config.setProperty(
						Environment.CURRENT_SESSION_CONTEXT_CLASS, SpringSessionContext.class.getName());
			}
			if (this.jtaTransactionManager != null) {
				// Set Spring-provided JTA TransactionManager as Hibernate property.
				config.setProperty(
						Environment.TRANSACTION_STRATEGY, JTATransactionFactory.class.getName());
				config.setProperty(
						Environment.TRANSACTION_MANAGER_STRATEGY, LocalTransactionManagerLookup.class.getName());
			}
			else {
				// Makes the Hibernate Session aware of the presence of a Spring-managed transaction.
				// Also sets connection release mode to ON_CLOSE by default.
				config.setProperty(
						Environment.TRANSACTION_STRATEGY, SpringTransactionFactory.class.getName());
			}

将 hibernate.current_session_context_class设为org.springframework.orm.hibernate3.SpringSessionContext

SpringSessionContext Implementation of Hibernate 3.1's CurrentSessionContext interface that delegates to Spring's SessionFactoryUtils for providing a Spring-managed current Session.

Used by Spring's LocalSessionFactoryBean when told to expose a transaction-aware SessionFactory. This is the default as of Spring 2.5.

This CurrentSessionContext implementation can also be specified in custom SessionFactory setup through the "hibernate.current_session_context_class" property, with the fully qualified name of this class as value.

    Object
