Hibernate常用方法之_插入

1、使用session的save方法进行插入

    public void saveUser(User user){

        Session session = null;
        Transaction transaction = null;
        try {
            session = HibernateUtils.getSession();
            transaction =session.beginTransaction();
            /*保存对象到数据库*/
            session.save(user);
            session.flush();
            transaction.commit();
        }catch (HibernateException e){/*catch可省略，数据库收不到提交会自动回滚*/
            if (transaction != null){
                transaction.rollback();
                throw e;
            }
        }finally {
            if (session != null){
                session.close();
            }
        }
    }
