Class LazyServiceFactoryBean

java.lang.Object
  org.kuali.rice.ksb.api.bus.support.LazyServiceFactoryBean

All Implemented Interfaces:

org.springframework.beans.factory.FactoryBean<Object>, org.springframework.beans.factory.InitializingBean

public class LazyServiceFactoryBean
extends Object
implements org.springframework.beans.factory.FactoryBean<Object>, org.springframework.beans.factory.InitializingBean

Loads a lazy proxy to a service from the ServiceBus. This proxy is created based on either the proxy interfaces that are injected into this bean, or derived from the objectType which is injected into this bean. If neither of these are injected, then an exception will be through during bean initialization. The attempt to fetch the resource from the ServiceBus won't be attempted until a method on the resulting proxy is invoked. If it fails to locate the resource, it will throw a ResourceLoaderException indicating the service could not be loaded.

This allows for referencing of a potentially remote service in the spring context during startup which won't get used until after startup. If the remote service gets used *during* startup, then it must be available from the GRL during startup or else the ResourceLoaderException will be thrown.
