hibernate查询时Criteria怎么根据级联的两个类里的属性进行查询？

有3个表，A，B，C，
关系如下：

A-->List，B属性有time等;
A-->List，C属性有time等
Java代码：
Entity：
@OneToMany(fetch = FetchType.EAGER)
@JoinColumn(name = "axxx_id")
@Fetch(FetchMode.SELECT)
public List getB() {
return b;
}

public void setB(List<B> b) {
    this.b = b;
}
@OneToMany(fetch = FetchType.EAGER)
@JoinColumn(name = "axxx_id")
@Fetch(FetchMode.SELECT)
public List<C> getC() {
    return c;
}

public void setC(List<C> c) {
    this.c = c;
}

Server:

Criteria countCriteria = entityDao.getCriteria();
Criteria listCriteria = entityDao.getCriteria();
...
//*********************start***************************
//加条件 当类为一时可以这样
{
    countCriteria.createAlias("B", "b");
    listCriteria.createAlias("B", "b");
    countCriteria.add(Restrictions.le("b.time", time));
    listCriteria.add(Restrictions.le("b.time", time));
}
//********************end***************************

//现在类为一个List型的，该怎么加条件??



listCriteria.setFirstResult((pageNo-1)*pageSize);  
listCriteria.setMaxResults(pageSize);
List<A> items = listCriteria.list();

hibernate查询时Criteria怎么根据两个time进行查询？

问题已经解决：

底层代码：　

 @Autowired
    @Qualifier("sessionFactory")
    protected SessionFactory sessionFactory;

    protected Session getSession() {
        return sessionFactory.getCurrentSession();
    }

    @Override
    public Criteria  getExecutableCriteria(){
        DetachedCriteria dc = DetachedCriteria .forClass(this.entityClass);
        return dc.getExecutableCriteria(getSession()); 
    }

service调用代码：

 Criteria listCriteria = entityDao.getExecutableCriteria();
listCriteria.createAlias("A","a",JoinType.LEFT_OUTER_JOIN);
listCriteria.createAlias("B","b",JoinType.LEFT_OUTER_JOIN);

listCriteria.add(Restrictions.or(Restrictions.lt("a.time", time, MatchMode.ANYWHERE),Restrictions.lt("b.time", time, MatchMode.ANYWHERE)));
... ...
