Question

hibernate中:session.getTransaction().commit();这句话怎么出错了，在myeclipse中显示错误

try {
session = factory.openSession();

//开启事务
session.beginTransaction();

User user = new User();
user.setName("张三");
user.setPassword("123");
user.setCreateTime(new Date());
user.setExpireTime(new Date());

//保存数据
session.save(user);

//提交事务
session.getTransaction().commit();
}catch(Exception e) {
e.printStackTrace();
//回滚事务
session.getTransaction().rollback();
}finally {
if (session != null) {
if (session.isOpen()) {
//关闭session
session.close();
}
}
}

}

Answer 1

把Session session = factory.openSession(); 放到try的前面去就可以了。
或者是
Session session=null;
try {
session = factory.openSession();
.......

Answer 2

应该是session.getTransaction().rollback(); 错了吧
varaible may not be initialized,变量未初始化

Answer 3

未初始化session
