Class AbstractSpringReference<T>

java.lang.Object
  org.wicketstuff.springreference.AbstractSpringReference<T>

Type Parameters:

T - type of the wrapped spring bean

All Implemented Interfaces:

Serializable, Cloneable

Direct Known Subclasses:

SpringReference

public abstract class AbstractSpringReference<T>
extends Object
implements Serializable, Cloneable

An abstract base class for referring spring beans.

This class supports serialization. The referred spring bean does not get serialized, after deserialization it is looked up again on the first access.

Subclasses must implement the getSupporter() method used to locate the AbstractSpringReferenceSupporter object. This class does not depend on wicket or spring-web. So in theory subclasses can be used in non-wicket, non-web spring applications too.
