org.hibernate.exception.SQLGrammarException：无法在org.hibernate.exception.SQLStateConverter

Question

**hibernate.cfg.xml:**:

SessionFactory sessionFactory = new Configuration（）。configure（＆＃34; hibernate.cfg.xml＆＃34;）。buildSessionFactory（）; //我在主类中使用的查询上面也没有用，但它显示了同样的事情...... ??

  

这是我的配置文件.....我怎么能跑出这个问题...... ??
