Example 1 with DefaultKafkaConsumerFactory

use of org.springframework.kafka.core.DefaultKafkaConsumerFactory in project spring-integration-samples by spring-projects.

the class Application method addAnotherListenerForTopics.

public void addAnotherListenerForTopics(String... topics) {
    Map<String, Object> consumerProperties = kafkaProperties.buildConsumerProperties();
