报这个异常java.lang.ClassCastException: 哪里错了啊

[lord_is_layuping]

异常如下：
Exception in thread "main" java.lang.ClassCastException: java.io.FileInputStream
at test.SimpleTest.testQuickStart(SimpleTest.java:18)
at test.SimpleTest.main(SimpleTest.java:26)

源码如下

package test;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;

import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.Resource;



import net.xiaxin.spring.qs.Action;


public class SimpleTest {
	public void testQuickStart() throws FileNotFoundException {
		InputStream is = new FileInputStream("bean.xml");
		XmlBeanFactory factory = new XmlBeanFactory((Resource) is);
		Action action = (Action) factory.getBean("TheAction");
		
		System.out.println(action.execute("Rod Johnson"));
	}
	
	public static void main(String[] args) throws FileNotFoundException {
		SimpleTest simpleTest = new SimpleTest();
		simpleTest.testQuickStart();
	}
}

Action action = (Action) factory.getBean("TheAction");


看下你这句强制转换的 类型到底匹配不？

[GkfSyser]

FileInputStream is = new FileInputStream("bean.xml")

类型转换错误

[Kevin-林]

Action action = (Action) factory.getBean("TheAction");
查看TheAction类是否继承了Action类

在 XmlBeanFactory factory = new XmlBeanFactory((Resource) is);
Action action = (Action) factory.getBean("TheAction");
每行之前打印测试消息看是那行转换失败

关注~顶

[Logson]

InputStream is = new FileInputStream("bean.xml");
这个错了

[jayccx]

XmlBeanFactory factory = new XmlBeanFactory((Resource) is);
这个错了

[xujiabo_bobo]

Action action = (Action) factory.getBean("TheAction");
类型转换失败
