Interface DisposableBean

All Known Implementing Classes:

AbstractPoolingTargetSource, ThreadLocalTargetSource, SingleConnectionDataSource, LocalSessionFactoryBean, LocalPersistenceManagerFactoryBean

public interface DisposableBean

Interface to be implemented by beans that want to release resources on destruction. A BeanFactory is supposed to invoke the destroy method if it disposes a cached singleton. An application context is supposed to dispose all of its singletons on close.

An alternative to implementing DisposableBean 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.
