Spring文件中的 SessionFactory中 加入为了能得到同一个Session <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();
