    C:\helloapp>可能太过于长了，不过没有办法，我已经尽力将不相干的内容排除了，请各位指点！因为我是刚刚接触这个，所以，各位的只言片语可能对我都会是莫大的帮助，谢谢！
      

  2.   

    把你的程序里
          Configuration config = new Configuration();
          config.addClass(Reginfo.class);
          config.addClass(Userpower.class);      
          config.addClass(Sql.class);
          config.addClass(Sqlstat.class);该成:
    Configuration config = new Configuration().configure();我把你贴出来的代码导进我的工程
    修改完后可以添加数据
    我的数据库是mysql
    hibernate.cfg.xml是按自己的数据库配置的
      

  3.   

    这是我的hibernate配置文件，我把相关的代码改了改，改为 
    Configuration config = new Configuration().configure();
          config.addClass(Reginfo.class);
          sessionFactory = config.buildSessionFactory();
    现在出错信息是这样的，看起来估计是建立 Configuration()对象的时候出现的错误，能请那位大虾解释一下么？

      </class></hibernate-mapping>
      

  4.   

    不用写config.addClass(Reginfo.class);
    加上去反而会出错addClass函数只当你用SchemaExport建表的时候才需要用到
    千万要记住!!!
