public interface DisposableBean

Interface to be implemented by beans that want to release resources on destruction. A BeanFactory will invoke the destroy method on individual destruction of a scoped bean. An org.springframework.context.ApplicationContext is supposed to dispose all of its singletons on shutdown, driven by the application lifecycle.

A Spring-managed bean may also implement Java's 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 BeanFactory javadocs.
