数据库添加成功了！但是页面报了这个错！

------解决方案--------------------
报的是事物没有开启。。
------解决方案--------------------

Could not commit Hibernate transaction; 


Transaction not successfully started
事务没有开启

Java code

//最好放在try catch里， 
try{

Session s = HibernateUtil.getSession();//从hibernateUtil拿到session
Transaction tx = s.getTransaction();//设置事务
tx.begin();//开启事务
 //do something...

tx.commit();//提交事务

}catch(Exception e){
     //捕获异常
    // 并且在catch里回滚事务
}

------解决方案--------------------
org.springframework.transaction.TransactionSystemException: Could not commit Hibernate transaction; nested exception is org.hibernate.TransactionException: Transaction not successfully started

事务 Transaction 没有开启
