Hibernate基础笔记

1.搭建时候，需要添加jar包，hibernate.cfg.xml文件
以及每个实体类对应table的xx.class->xx.hbm.xml
2.旧版配置执行代码

//配置
Configuration config = new Configuration().configure();

//注册服务
        ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(config.getProperties()).build();

//sessionfactory
        SessionFactory sessionFactory = config.buildSessionFactory(serviceRegistry);
        Session session = sessionFactory.openSession();
        session.beginTransaction();

        Student s = new Student();
        s.setName("yrj");
        session.save(s);

        session.getTransaction().commit();
        session.close();
        sessionFactory.close();

3.出现找不到类时候，工程的属性中buildpath可能有错误jar包，清除即可。
