Class StreamsBuilderFactoryBean

  • All Implemented Interfaces:
    org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.FactoryBean<org.apache.kafka.streams.StreamsBuilder>, org.springframework.beans.factory.InitializingBean, org.springframework.context.Lifecycle, org.springframework.context.Phased, org.springframework.context.SmartLifecycle
    public class StreamsBuilderFactoryBean
extends org.springframework.beans.factory.config.AbstractFactoryBean<org.apache.kafka.streams.StreamsBuilder>
implements org.springframework.context.SmartLifecycle, org.springframework.beans.factory.BeanNameAware
    An AbstractFactoryBean for the StreamsBuilder instance and lifecycle control for the internal KafkaStreams instance.

    A fine grained control on KafkaStreams can be achieved by KafkaStreamsCustomizers.
