即使使用注释或XML进行映射,我也面临同样的错误,调试时我注意到了这一行

factory = new MetadataSources( registry ).buildMetadata().buildSessionFactory();

永远不会执行,我的打印显示在休眠日志中:

这是休眠日志:

hibernate.cfg.xml中:

发生的功能

private static SessionFactory factory; 

protected void setUp() throws Exception {
        // A SessionFactory is set up once for an application!
        final StandardServiceRegistry registry = new StandardServiceRegistryBuilder()
                .configure() // configures settings from hibernate.cfg.xml
                .build();
        try {
            factory = new MetadataSources( registry ).buildMetadata().buildSessionFactory();
        }
        catch (Exception e) {
            System.out.println("Falha ao criar sessão");

            // The registry would be destroyed by the SessionFactory, but we had trouble building the SessionFactory
            // so destroy it manually.
            StandardServiceRegistryBuilder.destroy( registry );
        }
    }
