出现这种情况一般就是你的List 是一个没有值的对象(不是null),也就是里面什么对象也没有存(即:List.size()==0)。
但是,你有取它下标为0值的操作。所以,数组越界了!!比如List.get(0);
//根据邮箱查看账号信息
@Override
public Account findbyEmail(String email) throws Exception {
// TODO Auto-generated method stub
Account acc=new Account();
Session session=HibernateUtil.getSession();
String hql="from Account as acc where acc.email='"+email+"'";
Query q=session.createQuery(hql);
List list=q.list();
if(list!=null)
{
acc =(Account)list.get(0); //这里出错了
}
else
{
acc=null;
}
session.close();
return acc;
}
