Person類

public class Person {
	private int i = 0;

	public Person(){
		System.out.println("例項化一個物件");
	}
	
	public void init(){
		System.out.println("呼叫初始化方法....");
	}
	
	public void destory222(){
		System.out.println("呼叫銷燬化方法....");
	}
}

<?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">
	<!-- 配置初始化方法和銷燬方法，但是如果要銷燬方法生效scope="singleton" -->				
	<bean id="person" class="com.xxc.initAndDestory.domain.Person" scope="singleton" lazy-init="false" init-method="init" destroy-method="destory"></bean>
</beans>
 

public class Test {
	public static void main(String[] args) {
		//如果要呼叫銷燬方法必須用子類來宣告,而不是ApplicationContext,因為ApplicationContext沒有close()
		ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("com/xxc/initAndDestory/applicationContext.xml");
		Person p1 = (Person)ac.getBean("person");
		Person p2 = (Person)ac.getBean("person");
		ac.close();
	}
}
 

如果用註解方式配置：

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	   xmlns:context="http://www.springframework.org/schema/context" 
	   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  
                            http://www.springframework.org/schema/context   
                            http://www.springframework.org/schema/context/spring-context-2.5.xsd">  
							
	<context:annotation-config/> 
							
	<!-- scope預設是 prototype:getBean()一次建立一個例項-->
	<bean id="person" class="com.xxc.initAndDestory.domain.Person"></bean>
</beans>
 

public class Person {
	private int i = 0;

	public Person(){
		System.out.println("例項化一個物件");
	}
	@PostConstruct //初始化方法的註解方式  等同與init-method=init
	public void init(){
		System.out.println("呼叫初始化方法....");
	}
	@PreDestroy	//銷燬方法的註解方式  等同於destory-method=destory222
	public void destory(){
		System.out.println("呼叫銷燬化方法....");
	}
}
