消费者有时不工作,有时不工作,无法解决问题。

spring boot - 1.5.21.release
kafka client - 0.11.0.0
kafka servers - IBM event stream service on cloud.

应用程序属性:


# Producer

spring.kafka.template.default-topic=distitopic
spring.kafka.producer.client-id=event-streams-kafka
spring.kafka.producer.key-serializer=org.apache.kafka.common.serialization.StringSerializer
spring.kafka.producer.value-serializer=org.apache.kafka.common.serialization.StringSerializer

# Consumer

tier2.disti.search.topic=distitopic
spring.kafka.consumer.enable-auto-commit=false
spring.kafka.consumer.group-id=distigroup
spring.kafka.consumer.auto-offset-reset=latest
spring.kafka.consumer.key-deserializer=org.apache.kafka.common.serialization.StringDeserializer
spring.kafka.consumer.value-deserializer=org.apache.kafka.common.serialization.StringDeserializer

在我的rest控制器中,我有这个方法

@KafkaListener(topics = "${tier2.disti.search.topic}")
public void listen(ConsumerRecord<String, String> cr) throws Exception {

在websphereapplicationserver的系统输出日志中,我经常看到这些消息

您是在“bootstrap.servers”或fqdn中指定实际的以逗号分隔的主机名吗?当使用fqdn而不是直接使用主机名时,我遇到了类似的问题。
