Package org.springframework.context.support

Class SimpleThreadScope

java.lang.Object
org.springframework.context.support.SimpleThreadScope
All Implemented Interfaces:
org.springframework.beans.factory.config.Scope
public class SimpleThreadScope extends Object implements org.springframework.beans.factory.config.Scope
A simple thread-backed Scope implementation.

NOTE: This thread scope is not registered by default in common contexts. Instead, you need to explicitly assign it to a scope key in your setup, either through ConfigurableBeanFactory.registerScope(java.lang.String, org.springframework.beans.factory.config.Scope) or through a CustomScopeConfigurer bean.

SimpleThreadScope does not clean up any objects associated with it. It is therefore typically preferable to use a request-bound scope implementation such as org.springframework.web.context.request.RequestScope in web environments, implementing the full lifecycle for scoped attributes (including reliable destruction).

For an implementation of a thread-based Scope with support for destruction callbacks, refer to Spring by Example.

Thanks to Eugene Kuleshov for submitting the original prototype for a thread scope!
