java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Integer

由于Hibernate3.2.5版本的（select count(*)）查询返回的结果是个Long 不能强制转换：

publicintgetAllUserNum(){
Sessionsession=HiberSF.getSession();
try{
session.getTransaction().begin();

Longlo=(Long)session.createQuery("selectcount(*)fromUser").uniqueResult();
//解决办法把long型拆分字符串进行转换
Integersum=newInteger(String.valueOf(lo));
session.getTransaction().commit();
returnsum;
}catch(RuntimeExceptione){
session.getTransaction().rollback();
throwe;
//TODO:handleexception
}finally{
session.close();
}
}

public int getAllUserNum(){   
        Session session = HiberSF.getSession();   
        try {   
            session.getTransaction().begin();   
            //解决办法直接调用:HashCode();   
                        //count(*)也可以理解为返回一个Object的对象，然后直接   
                        //调用 hashCode();   
            Integer lo = (Integer)session.createQuery("select count(*) from User").uniqueResult().hashCode();      
            session.getTransaction().commit();   
            return sum;   
        } catch (RuntimeException e) {   
            session.getTransaction().rollback();   
            throw e;   
            // TODO: handle exception   
        } finally {   
            session.close();   
        }   
    }
