Hibernate不能自动建表问题解决

hibernate.cfg.xml中dialect 配置方言为org.hibernate.dialect.MySQLInnoDBDialect是不能自动建表，改为org.hibernate.dialect.MySQLDialect或org.hibernate.dialect.MySQL5Dialect

另外hbm2ddl.auto设置为update即可

另附SessionFactoryFactory

public class HibernateUtil {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    public static SessionFactory buildSessionFactory(){
        try{
            // Create the SessionFactory from hibernate.cfg.xml
            Configuration cfg = new Configuration().configure();
            SessionFactory sf = cfg.buildSessionFactory(new StandardServiceRegistryBuilder().applySettings(cfg.getProperties()).build());
            return sf;
        }catch (Throwable ex){
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation filaed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory(){
        return sessionFactory;
    }

}
