spring中init-method和destroy-method配置

//Person类

public class Person {
	private int i = 0;
 
	public Person(){
		System.out.println("实例化一个对象");
	}
	
	public void init(){
		System.out.println("调用初始化方法....");
	}
	
	public void destory222(){
		System.out.println("调用销毁化方法....");
	}
}

applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
		xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
		xsi:schemaLocation="http://www.springframework.org/schema/beans 
							http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
	<!-- 配置初始化方法和销毁方法，但是如果要销毁方法生效scope="singleton" -->				
	<bean id="person" class="com.xxc.initAndDestory.domain.Person" scope="singleton" lazy-init="false" init-method="init" destroy-method="destory"></bean>
</beans>

测试类：
public class Test {
	public static void main(String[] args) {
		//如果要调用销毁方法必须用子类来声明,而不是ApplicationContext,
		//因为ApplicationContext没有close()
		ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("com/xxc/initAndDestory/applicationContext.xml");
		Person p1 = (Person)ac.getBean("person");
		Person p2 = (Person)ac.getBean("person");
		ac.close();
	}
}
