query.list()报空指针异常

[未尝不是一种方式]

代码如下：
public List findOwnerFamily(User u){
List list = null;
Session session = SessionFactory.currentSession();
Transaction t = null;
try{
t = session.beginTransaction();
Query query = session.createQuery("from Family f where f.user.userEp=?").setParameter(0, u.getUserEp());
System.out.println("--1--"+query.iterate().hasNext());
System.out.println("--2--"+query == null);
if(query != null){
list = query.list();
}
t.commit();
}catch(Exception e){
t.rollback();
e.printStackTrace();
}finally{
session.close();
}
System.out.println("--3--"+list.size());
return list;
}
打印处1: true
2: false
3: 未打印

就是在list = query.list();的地方报空指针异常。。。不知道是怎么回事。。
明明query和query.iterator.hasnext()都是有值的。。。

不知道啊。。。其他的方法有跟这个方法差不多的都没问题。。就这个方法有问题。。以前还好着呢。。。今天就不行了。。。唉。。。我重启下算了。。

上面就是这个方法单独拿出来运行出的问题。。。我也感到很奇怪。。。就是在226行（list = query.list();）这个地方报的错。。。其他跟这个方法类似的也没出错。。。所以我现在只能是考虑是否是配置文件错误了

哈哈 解决了。。但不知道为什么。。
只要在hbm中加个lazy="false"就可以了
