* Interface to be implemented by beans that want to release resources on destruction.
* A {@link BeanFactory} will invoke the destroy method on individual destruction of a
* scoped bean. An {@link org.springframework.context.ApplicationContext} is supposed
* to dispose all of its singletons on shutdown, driven by the application lifecycle.
*
* <p>A Spring-managed bean may also implement Java's {@link AutoCloseable} interface
* for the same purpose. An alternative to implementing an interface is specifying a
* custom destroy method, for example in an XML bean definition. For a list of all
* bean lifecycle methods, see the {@link BeanFactory BeanFactory javadocs}.
