org.hibernate.HibernateException: No Session found for current thread

Spring3.1.1 Intergrate with Hibernate 4.0.1 occurs the

 

org.hibernate.HibernateException: No Session found for current thread

 

In the applicationContext.xml configuration:

 

this configuration should like this

 

<tx:advice id="txAdvice" transaction-manager="txManager">
		<tx:attributes>
			<tx:method name="get*" read-only="true" propagation="REQUIRED"/>
			<tx:method name="*" propagation="REQUIRED"/>
		</tx:attributes>
</tx:advice>

 

it seems that propagation set values[SUPPORTS|NOT_SUPPORTED|NEVER] will issue

 

No Session found for the current thread

这个问题 在我的这篇帖子中提到过http://www.iteye.com/topic/1120924



补充spring3.1.1源代码分析当 传播行为为 Support时报 org.hibernate.HibernateException: No Session found for current thread 异常：

spring3.1开始 不提供（没有这个东西了）Hibernate4的 DaoSupport和Template，，而是直接使用原生的Hibernate4 API

如在 Hibernate3中 HibernateTemplate中有如下代码
Java代码  
protected Session getSession() { 
        if (isAlwaysUseNewSession()) { 
            return SessionFactoryUtils.getNewSession(getSessionFactory(), getEntityInterceptor()); 
        } 
        else if (isAllowCreate()) {//默认是true，也就是即使你的传播行为是Supports也一定会有session存在的 
            return SessionFactoryUtils.getSession( 
                    getSessionFactory(), getEntityInterceptor(), getJdbcExceptionTranslator()); 
        } 
        else if (SessionFactoryUtils.hasTransactionalSession(getSessionFactory())) { 
            return SessionFactoryUtils.getSession(getSessionFactory(), false); 
        } 
        else { 
            try { 
                return getSessionFactory().getCurrentSession(); 
            } 
            catch (HibernateException ex) { 
                throw new DataAccessResourceFailureException("Could not obtain current Hibernate Session", ex); 
            } 
        } 
    } 

但我们使用的是Hibernate4原生API，使用SpringSessionContext获取session，而这个isAllowCreate选项默认为false

Java代码  
/**
* Retrieve the Spring-managed Session for the current thread, if any.
*/ 
public Session currentSession() throws HibernateException { 
    try { 
        return (org.hibernate.classic.Session) SessionFactoryUtils.doGetSession(this.sessionFactory, false);//最后的false即是 
    } 
    catch (IllegalStateException ex) { 
        throw new HibernateException(ex.getMessage()); 
    } 
} 



SessionFactoryUtils类
Java代码  
public static Session doGetSession(SessionFactory sessionFactory, boolean allowCreate) 
        throws HibernateException, IllegalStateException { 
 
    return doGetSession(sessionFactory, null, null, allowCreate); 
} 

可否认为这是集成Hibernate4的bug，或者采用OpenSessionInView模式解决或者传播行为最低为Required。
