Spring IOC的缓存

1、将上一篇的测试代码修改如下

public class SpringTest {

	public static void main(String[] args) {

		ClassPathResource resource = new ClassPathResource("com/example/spring/beans.xml");
		DefaultListableBeanFactory factory = new DefaultListableBeanFactory();

		XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader(factory);

		reader.loadBeanDefinitions(resource);

		Person person = (Person)factory.getBean("person");

		System.out.println(person.say());

		Person person2 = (Person)factory.getBean("person");

		System.out.println(person == person2);

	}
}

　　输出结果：

Hello,Tom
true

　　说明person和person2是同一个对象

如果此时在beans.xml增加属性scope="prototype"，

则输出结果为false

Hello,Tom
false
