hibernate.cfg.xml中

hibernate.reveng.xml中

PoolManeger.java（HybernateUtil.java）

package DB;

import javax.imageio.spi.ServiceRegistry;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;

/**
 * Hibernate Utility class with a convenient method to get Session Factory
 * object.
 *
 * @author scc
 */
public class PoolManager {

    private static final SessionFactory sessionFactory;

    static {
        try {
            // Create the SessionFactory from standard (hibernate.cfg.xml) 
            // config file.
            //sessionFactory = new Configuration().configure().buildSessionFactory();
             Configuration configuration = new Configuration().configure();
            StandardServiceRegistry serviceRegistry
                = new StandardServiceRegistryBuilder()
                    .applySettings(configuration.getProperties()).build();

            // builds a session factory from the service registry
            sessionFactory = configuration.buildSessionFactory(serviceRegistry);
        } catch (Throwable ex) {
            // Log the exception. 
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}

我搜索了很多，有一些接近这个问题，但没有回答据我所知，sessionFactory创建失败并且我正在使用Hybernate4.3.x（jpa2.1），我无法找到原因以及如何发生这种情况。如果有人知道，请帮助。

Answer 1

（1）您没有在hibernate.cfg.xml

中添加以下属性

hibernate.connection.password

（2）您可以尝试使用以下代码加载sessionFactory，我使用的是hibernate版本4.3.7

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

public class HibernateUtil {
    private static final SessionFactory sessionFactory = buildSessionFactory();

    /**
     * One connection from a DB requires only one instance of sessionFactory in
     * an application.
     * 
     * @return SessionFactory
     */
    private static SessionFactory buildSessionFactory() {
        Configuration configuration = new Configuration();
        configuration.configure();
        ServiceRegistry serviceRegistry = new ServiceRegistryBuilder()
                .applySettings(configuration.getProperties())
                .buildServiceRegistry();
        return configuration.buildSessionFactory(serviceRegistry);
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public static void shutdown() {
        // Close caches and connection pools
        getSessionFactory().close();
    }
}

Answer 2

像这样创建会话工厂和会话

SessionFactory sessionfactory =  new Configuration().configure().buildSessionFactory();
Session session = sessionfactory.openSession();

无法创建sessionFactory
