Class PulsarListenerAnnotationBeanPostProcessor<V>

java.lang.Object

org.springframework.pulsar.annotation.AbstractPulsarAnnotationsBeanPostProcessor

org.springframework.pulsar.annotation.PulsarListenerAnnotationBeanPostProcessor<V>

Type Parameters:

V - the payload type.

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.config.BeanPostProcessor, org.springframework.beans.factory.InitializingBean, org.springframework.beans.factory.SmartInitializingSingleton, org.springframework.context.ApplicationContextAware, org.springframework.core.Ordered

public class PulsarListenerAnnotationBeanPostProcessor<V>
extends AbstractPulsarAnnotationsBeanPostProcessor
implements org.springframework.beans.factory.SmartInitializingSingleton

Bean post-processor that registers methods annotated with PulsarListener to be invoked by a Pulsar message listener container created under the covers by a PulsarListenerContainerFactory according to the parameters of the annotation.

Annotated methods can use flexible arguments as defined by PulsarListener.

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

Auto-detect any PulsarListenerConfigurer 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 EnablePulsar Javadoc for complete usage details.
