Package org.springframework.cloud.stream.binder.kafka.streams

Class StreamsBuilderFactoryManager

java.lang.Object

org.springframework.cloud.stream.binder.kafka.streams.StreamsBuilderFactoryManager

All Implemented Interfaces:

org.springframework.context.Lifecycle, org.springframework.context.Phased, org.springframework.context.SmartLifecycle

public class StreamsBuilderFactoryManager
extends Object
implements org.springframework.context.SmartLifecycle

Iterate through all StreamsBuilderFactoryBean in the application context and start them. As each one completes starting, register the associated KafkaStreams object into InteractiveQueryService. This SmartLifecycle class ensures that the bean created from it is started very late through the bootstrap process by setting the phase value closer to Integer.MAX_VALUE. This is to guarantee that the StreamsBuilderFactoryBean on a StreamListener method with multiple bindings is only started after all the binding phases have completed successfully.
