java.lang.ClassCastException: java.lang.Float cannot be cast to java.lang.Inte,该如何处理

java.lang.ClassCastException: java.lang.Float cannot be cast to java.lang.Inte

if(this.cardDao==null)

this.cardDao=(CardDao)MyBeanFactory.MyGetBean("cardDao");
}
if(this.historyDao==null)

this.historyDao=(HistoryDao)MyBeanFactory.MyGetBean("historyDao");
}
Card card=this.cardDao.queryById(this.cardId);
System.out.println("选择的卡号为："+cardId);
System.out.println("卡里还有的钱："+card.getBalance());
this.session.put("card",card);
List<History> listOfHistory=this.historyDao.queryByCard(this.cardId);//问题就在这里
System.out.println("此卡共有消费记录条数："+listOfHistory.size());
this.session.put("listOfHistory", listOfHistory);
return "success";
}
}

下面是控制台的输出：
正在执行choiseCard请求！
选择的卡号为：7951
卡里还有的钱：100.0

问题是listOfHistory=this.historyDao.queryByCard(this.cardId)；中如果我把this.cardId改成7951就能运行通过，但是用this.cardId就会报错：
