Package org.springframework.amqp.rabbit.test

Class RabbitListenerTestHarness

java.lang.Object

org.springframework.amqp.rabbit.annotation.RabbitListenerAnnotationBeanPostProcessor

org.springframework.amqp.rabbit.test.RabbitListenerTestHarness

All Implemented Interfaces:

Aware, BeanClassLoaderAware, BeanFactoryAware, BeanPostProcessor, SmartInitializingSingleton, EnvironmentAware, Ordered

public class RabbitListenerTestHarness
extends RabbitListenerAnnotationBeanPostProcessor

BeanPostProcessor extending RabbitListenerAnnotationBeanPostProcessor. Wraps the listener bean in a CGLIB proxy with an advice to capture the arguments and result (if any) in a blocking queue. Test cases can access the results by autowiring the test harness into test cases.
