休眠不將數據保存到數據庫

Question

@Override
public void service(HttpServletRequest req,HttpServletResponse res) throws IOException {        
   Session s = NewHibernateUtil.getSessionFactory().openSession();
   Employ e = new Employ();
   e.setName("JoisCreaations");
   e.setId(2);
   Transaction t = s.beginTransaction();
   try {       
     t.begin();
     s.save(e);
     t.commit();
   }
   catch(Exception ss) {              
     t.rollback();
   }
   finally {
     s.close();
   }

   PrintWriter out = res.getWriter();
   out.println("SucesfullyAdded");

}

這是我的代碼。 有人可以告訴我為什么它不保存數據！！！ 沒有錯誤！ 一切都很好

我什至設置了配置文件並正確映射了所有內容

嗨蘇曼思

試試這個代碼。 我希望這對你有用。

@Override
public void service(HttpServletRequest req,HttpServletResponse res) throws IOException{
    SessionFactory sf = HibernateUtil.getSessionFactory();
    org.hibernate.Session ss = sf.openSession();
    Transaction tx = ss.beginTransaction();
    try {
        Employ e = new Employ();
        e.setName("JoisCreaations");
        e.setId(2);
        ss.save(e);
        tx.commit();
    } catch (Exception ee) {
        tx.rollback();
    } finally {
        ss.close();
    }
    PrintWriter out = res.getWriter();
    out.println("SucesfullyAdded");
}
