我有一个线程，偶尔会列出消息中心的主题。但偶尔，我会收到一个：发送ssl关闭消息失败。
有什么想法吗？

KafkaConsumer<String, String> consumer = new KafkaConsumer<>(getConsumerConfiguration());
try {
    Map<String, List<PartitionInfo>> topics = consumer.listTopics();
    return new ArrayList<String>(topics.keySet());
} finally {
    if (consumer != null) {
      **consumer.close();**
    }
}

我收到消费者的警告。关闭。
耗电元件的配置：
sasl.mechanism=普通
security.protocol=sasl\u ssl协议
group.id=消费者1
ssl.enabled.protocol=tlsv1.2
ssl.endpoint.identification.algorithm=https
ssl.protocol=tlsv1.2协议
sasl.jaas.config=org.apache.kafka.common.security.plain.plainloginmodule所需用户名=“用户名”密码=“密码”；
