Hibernate常用方法之_插入

1、使用session的save方法进行插入

 1     public void saveUser(User user){
 2 
 3         Session session = null;
 4         Transaction transaction = null;
 5         try {
 6             session = HibernateUtils.getSession();
 7             transaction =session.beginTransaction();
 8             /*保存对象到数据库*/
 9             session.save(user);
10             session.flush();
11             transaction.commit();
12         }catch (HibernateException e){/*catch可省略，数据库收不到提交会自动回滚*/
13             if (transaction != null){
14                 transaction.rollback();
15                 throw e;
16             }
17         }finally {
18             if (session != null){
19                 session.close();
20             }
21         }
22     }
