java.lang.ClassCastException: com.sinews是什么异常

Question

java.lang.ClassCastException: com.sinews.insurance.entity.HotCustomerVisitLog cannot be cast to org.hibernate.Query
这个是什么异常？
怎么解决？
我的daoimpl是这样子写的：
public HotCustomerVisitLog findHotCustomerVisitLogByCusNo(int customerNo)
throws isException {
String hql="from HotCustomerVisitLog where customerNo ="+customerNo;
System.out.println("$$$$$$$:"+hql);
Session session=this.getSession();
Query query = (Query) session.createQuery(hql).uniqueResult();
return(HotCustomerVisitLog)query;
}

Answer 1

[quote]Query query = (Query) session.createQuery(hql).uniqueResult(); [/quote]
这一句写错了 session.createQuery(hql) 已经是一个Query类型对象了 再加上.uniqueResult()应该返回一个HotCustomerVisitLog对象;

应该写成HotCustomerVisitLog h = session.createQuery(hql).uniqueResult();
