Caused by: org.hibernate.HibernateException: Connection cannot be null when 'hibernate.dialect' not set
docs.jboss.org文档示例代码:(http://docs.jboss.org/hibernate/annotations/3.5/reference/en/html_single/)
1 static { 2 try { 3 sessionFactory = new AnnotationConfiguration() 4 .configure().buildSessionFactory(); 5 } catch (Throwable ex) { 6 // Log exception! 7 throw new ExceptionInInitializerError(ex); 8 } 9 }
测试时出现Caused by: org.hibernate.HibernateException: Connection cannot be null when ‘hibernate.dialect‘ not set
自己依赖的是hibernate-core-4.2.7.Final.jar
改成:
1 Configuration cfg = new Configuration().configure(); 2 ServiceRegistry serviceRegistry= new ServiceRegistryBuilder().applySettings(cfg.getProperties()).buildServiceRegistry(); 3 sessionFactory = cfg.buildSessionFactory(serviceRegistry);
Hibernate官网上找不到说明。网上找的。
