用HIBERNATE时出现如下错误：

ERROR - Could not locate SessionFactory in JNDI
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial
 at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645)

Exception in thread "main" java.lang.IllegalStateException: Could not locate SessionFactory in JNDI

需要修改的两个地方：

    protected SessionFactory getSessionFactory() {

        try {

            //return (SessionFactory) new InitialContext().lookup("SessionFactory");这句不能通过，会提示Could not locate SessionFactory in JNDIjavax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

 

      修改为

      return (SessionFactory) new Configuration().configure().buildSessionFactory();

        }

        catch (Exception e) {

            log.error("Could not locate SessionFactory in JNDI", e);

            throw new IllegalStateException("Could not locate SessionFactory in JNDI"+e.toString());

        }

    }

 

 

 

    public Tb1 findById( java.lang.String id) {

        log.debug("getting Tb1 instance with id: " + id);

        try {

                  System.out.println("test0....."+sessionFactory);

//Tb1 instance= (Tb1)sessionFactory.getCurrentSession().get(“com.sss.common”,id);//这句有问题。会提示No CurrentSessionContext configured!

               修改为如下两句

Session session = sessionFactory.openSession();//先加入import org.hibernate.Session;

            //Tb1 instance = (Tb1) session.load("com.sss.commmon.Tb1", id);这句也可以

               Tb1 instance = (Tb1) session.get("com.sss.commmon.Tb1", id);

              

            if (instance==null) {

                log.debug("get successful, no instance found");

            }

            else {

                log.debug("get successful, instance found");

            }

            return instance;

        }

        catch (RuntimeException re) {

            log.error("get failed", re);

            throw re;

        }
