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();
             }
         }
     }
