第三方登录:jsp中application.getAttribute()的返回类型是什么? - ITeye问答
&%@ page import="java.util.*"%&
&%@ page language="java" contentType="text/charset=gb2312"%&
&html&
&body&
&%
&
& if(application.getAttribute("num")==null)
& {
&&& application.setAttribute("num","1");
& }
& else{
&&& num=Integer.parseInt((String)application.getAttribute("num"));//mark
&&& num++;
&&& application.setAttribute("num",Integer.toString(num));
&&& out.println(application.getAttribute("num").getClass().getName());
&&& out.println((String)application.getAttribute("num").getClass().getName());
& }
%&
&h1&这个页面已经被浏览了&%=(String)application.getAttribute("num")%&次&/h&
&/body&
&/html&
------------------------------输出----------------------------------
既然application.getAttribute("num")返回类型是String,那么为什么把//mark处的代码改为num=Integer.parseInt(application.getAttribute("num");则会提示:The method parseInt(String) in the type Integer is not applicable for the arguments (Object)?
采纳的答案
因为你往里面放的就是String 所以获取的时候就是java.lang.String 若是你往里面放Integer,则取出来就是java.lang.Integer,
所以application.getAttribute("num").getClass().getName()取出来是实际的数据类型
但是application.getAttribute("num")取出来的是Object,因为Object是所有的类的父类,你可以使用instanceof进行判断
第一,返回的是Object,需要强转
第二,String也属于object
第三,application.getAttribute("num").getClass().getName()里的
getname()方法返回的是一个字符串
说有的getAttribute()方法返回的都是Object对象。需要强制类型转换。
1、application.getAttribute("num")返回的是Object类型的,不是String类型的。
2、Integer.parseInt(String)参数为String类型不是Object类型。
3、你的写法太复杂了,可以直接Integet num = (Integer)application.getAttribute("num")。
