org.springframework.web.context.request

Class AbstractRequestAttributesScope

java.lang.Object

org.springframework.web.context.request.AbstractRequestAttributesScope

All Implemented Interfaces:

org.springframework.beans.factory.config.Scope

Direct Known Subclasses:

RequestScope, SessionScope

public abstract class AbstractRequestAttributesScope
extends Object
implements org.springframework.beans.factory.config.Scope

Abstract Scope implementation that reads from a particular scope in the current thread-bound RequestAttributes object.

Subclasses simply need to implement getScope() to instruct this class which RequestAttributes scope to read attributes from.

Subclasses may wish to override the get(java.lang.String, org.springframework.beans.factory.ObjectFactory<?>) and remove(java.lang.String) methods to add synchronization around the call back into this superclass.

Since:

2.0
