如何销毁/清除使用Spring MVC中的applicationcontext.xml文件创建的对象？

Question

I am creating Web application using Spring 3.2.1...

I have injected number of beans from my ApplicationContext.xml file, Its gets initialized and works fine.

Now my Issue is, I want to destroy some of those(not all object) objects created using ApplicationContext.xml manually.

Is it possible to destroy particular objects created using applicationcontext.xml file? If so please let me know the way to achieve it..

Thanks in advance...

The following snippet demonstrates how to remove a bean from the ApplicationContext.

ConfigurableListableBeanFactory configurableListableBeanFactory = context
        .getBeanFactory();

BeanDefinitionRegistry beanDefinitionRegistry = (BeanDefinitionRegistry) configurableListableBeanFactory;
// Removing the bean from container
beanDefinitionRegistry.removeBeanDefinition("demo");

To retrieve the ApplicationContext from a controller simply autowire the context.

private @Autowired
ApplicationContext context;
