求大虾hibernate事物问题

Question

错误提示；current autocommit status: false，
代码public class example {
    public void addUser(S s) throws HibernateException {
       //获得Hibernate session
       Session session = HibernateSessionFactory.getSession();
       Transaction tx =session.beginTransaction();
       //将s对象内容保存到数据库
       session.save(s);
       session.flush();
       tx.commit();
       //关闭Hibernate session
      // HibernateSessionFactory.closeSession();
       //session.close();
    }
   
    public static void main(String[] msg) {
       example example = new example();
       S s = new S();
       s.setSno(57);
       s.setSname("1234");
       try {
        example.addUser(s);
       } catch (HibernateException e) {}
      
    }
}

Answer 1

你把   session.flush(); 去掉试试

Answer 2

不行的去了也不行，
错误信息：
DEBUG - begin
DEBUG - opening JDBC connection
DEBUG - current autocommit status: false

Answer 3

你的代码顺序有错误   你应该先commit  再flush。试试吧。

Answer 4

DEBUG - current autocommit status: false
这个不是错误信息吧，你确定数据没插进去？

DEBUG 和INFO 不是异常,不用细看.

Answer 9

应该是没有映射，可是我.cfg跟.hbm文件都是写的了
