Class AzureListenerAnnotationBeanPostProcessor

java.lang.Object

com.microsoft.azure.spring.messaging.config.AzureListenerAnnotationBeanPostProcessor

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.config.BeanPostProcessor, org.springframework.beans.factory.SmartInitializingSingleton, org.springframework.beans.factory.support.MergedBeanDefinitionPostProcessor, org.springframework.core.Ordered

public class AzureListenerAnnotationBeanPostProcessor
extends Object
implements org.springframework.beans.factory.support.MergedBeanDefinitionPostProcessor, org.springframework.core.Ordered, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.SmartInitializingSingleton

Bean post-processor that registers methods annotated with AzureMessageListener to be invoked by a Azure message listener container created under the cover by a ListenerContainerFactory according to the attributes of the annotation.

Annotated methods can use flexible arguments as defined by AzureMessageListener.

This post-processor is automatically registered by the EnableAzureMessaging annotation.

Autodetects any AzureListenerConfigurer instances in the container, allowing for customization of the registry to be used, the default container factory or for fine-grained control over endpoints registration. See the EnableAzureMessaging javadocs for complete usage details.
