<prop key="hibernate.current_session_context_class">thread</prop>

然后

Resource resource=new ClassPathResource("/WEB-INF/applicationContext.xml");

BeanFactory factory=new XmlBeanFactory(resource);

SessionFactory sessionFactory = (SessionFactory)factory.getBean("sessionFactory");

就可以得到了

剩下的 不会就回炉吧，我 的 做法是 修改HibernateUtil文件的得到SessionFactory 的方法就 什么都解决了

import org.hibernate.HibernateException;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.hibernate.cfg.Configuration;

import org.springframework.beans.factory.BeanFactory;

import org.springframework.beans.factory.xml.XmlBeanFactory;

import org.springframework.core.io.ClassPathResource;

import org.springframework.core.io.Resource;

//在hibernate托管给Spring时得到sessionFactory

public class HibernateUtil {

private static final SessionFactory sessionFactory;

static {

try {

Resource resource=new ClassPathResource("/WEB-INF/applicationContext.xml");

BeanFactory factory=new XmlBeanFactory(resource);

sessionFactory = (SessionFactory)factory.getBean("sessionFactory");

} catch (HibernateException ex) {

throw new RuntimeException("Exception building SessionFactory: "

+ ex.getMessage(), ex);

}

}

public static final ThreadLocal session = new ThreadLocal();

public static Session currentSession() throws HibernateException {

Session s = (Session) session.get();

// Open a new Session, if this Thread has none yet

if (s == null) {

s = sessionFactory.openSession();

session.set(s);

}

return s;

}

public static void closeSession() throws HibernateException {

Session s = (Session) session.get();

session.set(null);

if (s != null)

s.close();

}

}

//

当hibernate没有托管给Spring使用这种和传统方式都可以得到啊

sessionFactory = new Configuration().configure("/WEB-INF/hibernate.cfg.xml")

.buildSessionFactory();
