Class PulsarReaderAnnotationBeanPostProcessor<V>

java.lang.Object

org.springframework.pulsar.annotation.AbstractPulsarAnnotationsBeanPostProcessor

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

Type Parameters:

V - the payload type.

All Implemented Interfaces:

Aware, BeanPostProcessor, InitializingBean, SmartInitializingSingleton, ApplicationContextAware, Ordered

public class PulsarReaderAnnotationBeanPostProcessor<V>
extends AbstractPulsarAnnotationsBeanPostProcessor
implements 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 PulsarReaderContainerFactory 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.
