还是spring中hibernate.current_session_context_class问题

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.
