/**
 * {@link FactoryBean} for AMQP proxies. Exposes the proxied service for use as a bean reference, using the specified
 * service interface. Proxies will throw Spring's unchecked RemoteAccessException on remote invocation failure.
 *
 * 

* This is intended for an "RMI-style" (i.e. synchroneous) usage of the AMQP protocol. Obviously, AMQP allows for a much * broader scope of execution styles, which are not the scope of the mechanism at hand. *

* Calling a method on the proxy will cause an AMQP message being sent according to the configured * {@link org.springframework.amqp.core.AmqpTemplate}. * This can be received and answered by an {@link org.springframework.amqp.remoting.service.AmqpInvokerServiceExporter}. * * @author David Bilge * @author Gary Russell * * @since 1.2 * @see #setServiceInterface * @see AmqpClientInterceptor * @see org.springframework.remoting.rmi.RmiServiceExporter * @see org.springframework.remoting.RemoteAccessException * @deprecated will be removed in 3.0.0. */ @Deprecated public class AmqpProxyFactoryBean extends AmqpClientInterceptor implements FactoryBean, InitializingBean { private Object serviceProxy; @Override public void afterPropertiesSet() { if (getServiceInterface() == null) { throw new IllegalArgumentException("Property 'serviceInterface' is required"); } this.serviceProxy = new ProxyFactory(getServiceInterface(), this).getProxy(getBeanClassLoader()); } @Override public Object getObject() { return this.serviceProxy; } @Override public Class getObjectType() { return getServiceInterface(); } @Override public boolean isSingleton() { return true; } }
