问题描述

关于hibernate的一个问题

代码别写完以后总是显示：SessionFactory/Configuration cannot be resolved错误。为什么啊？是hibernate没配置正确吗？可我已经配置了Hibernate.cfg.xml文件了啊，怎么解决呢？

package org.hibernate.entity;

import org.hibernate.*;
import org hibernate.cfg.*;

public class HibernateUtil {
private static SessionFactory sessionFactory;
private static final ThreadLocal threadLocal=new ThreadLocal();

static{
    try {
        Configuration cfg=new Configuration().configure();
        SessionFactory=cfg.buildSessionFactory();
    } catch (Throwable ex) {
        throw new ExceptionInInitializerError(ex);
    }
}

public static SessionFactory getSessionFactory(){
    return sessionFactory;
}

public static Session getSession() throws HibernateException{
    Session session=(session)threadLocal.get();
    if(session==null||session.isOpen()){
        if(sessionFactory==null){
            rebuildSessionFactory();
        }
        session=(sessionFactory!=null)?sessionFactory.openSession():null;
        threadLocal.set(session);
    }
    return session;
}

public static void closeSession() throws HibernateException{
    Session session=(session)threadLocal.get();
    threadLocal.set(null);
    if(session!=null){
        session.close();
    }
}

public static void rebuildSessionFactory(){
    try {
        configuration.configure(/hibernate.cfg.xml);
        sessionFactory=cofiguration.buildSessionFactory();
    } catch (Exception e) {
        System.err.println("Error Creating SessionFactory!");
        e.printStackTrace();
    }
}

public static void shutdown(){
    getSessionFactory.close();
}

}

解决方案

struts1 + hibernate3 做个一个网购项目的问题

解决方案二：

检查下import导入的类是不是Hibernate的，可能项目中有其他同名类被import了。
