Example 1 with IntegrationFlow

use of org.springframework.integration.dsl.IntegrationFlow in project spring-integration-samples by spring-projects.

the class Application method addAnotherListenerForTopics.

public void addAnotherListenerForTopics(String... topics) {
    Map<String, Object> consumerProperties = kafkaProperties.buildConsumerProperties();
    // change the group id so we don't revoke the other partitions.
    consumerProperties.put(ConsumerConfig.GROUP_ID_CONFIG, consumerProperties.get(ConsumerConfig.GROUP_ID_CONFIG) + "x");
    IntegrationFlow flow = IntegrationFlows.from(Kafka.messageDrivenChannelAdapter(new DefaultKafkaConsumerFactory<String, String>(consumerProperties), topics)).channel("fromKafka").get();
    this.flowContext.registration(flow).register();
}
