Spring init and destroy methods

package com.idol;

public class Auditorium {       
Auditorium(){
}  
public void turnOnLights() {  
    System.out.println("Lights are turned on"); 
}  
public void turnOffLights(){  
    System.out.println("Lights are turned off");
}

}

For xml context I have:

 <bean id="Auditorium" class="com.idol.Auditorium" init-method="turnOnLights" destroy-method="turnOffLights"/>

Testing:

ApplicationContext auditorium =
        new ClassPathXmlApplicationContext("ApplicationContextVer6.xml"); 

auditorium.getBean("Auditorium");

I get:

Does only print "Lights are turned on" and doesn't print "Lights are turned off". I though that before destroying the bean it should invoke the destroy-method too, what am I missing or not getting? (I have no errors in log, just in case)

Thanks

You cannot observe destroy method working, because beans are available in Spring context all the time. When you close/destroy your application context, then all beans instantiated within it should be destroyed. Take a look at the close() and destroy() methods at the org.springframework.context.support.AbstractApplicationContext class.

Try it like this:

final ConfigurableApplicationContext auditorium =
        new ClassPathXmlApplicationContext("ApplicationContextVer6.xml");
auditorium.getBean("Auditorium");
auditorium.close(); // thx Nathan

// auditorium.refresh() will also turn the lights off
// before turning them on again
