在向 msk(kafka 2.1.0) 生成消息时，我得到了

“向主题 AWSKafkaTopic发送消息时引发异常key='null'”payload='Message->0'

我正在尝试使用 docker 从部署在 EC2 上的 springboot 应用程序生成它。但是当我尝试使用 kafka-console-producer.sh 从同一个 EC2 客户端生成消息时，生产者工作正常。

bin/kafka-console-producer.sh --broker-list "XXBootstrapBrokerStringTlsXX" --producer.config client.properties --topic AWSKafkaTopic

我已经在本地使用 kafka 2.3.0 和 zookeeper 尝试了相同的程序，它在那里运行良好（在 docker 上运行 springboot 应用程序）。

Config-> 
    @Value("${spring.kafka.producer.bootstrap-servers}")
        private String bootstrapServers;

        @Bean
        public Map<String, Object> producerConfigs() {
            Map<String, Object> props = new HashMap<>();
            props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG,bootstrapServers);    props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG,StringSerializer.class);        props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG,StringSerializer.class);
            return props;
        }

        @Bean
        public ProducerFactory<String, String> producerFactory() {
            return new DefaultKafkaProducerFactory<>(producerConfigs());
        }

        @Bean
        public KafkaTemplate<String, String> kafkaTemplate() {
            return new KafkaTemplate<>(producerFactory());
        }

        @Bean
        public Sender sender() {
            return new Sender();
        }


Client->
     @Autowired
        private KafkaTemplate<String,String> kafkaTemplate;

        public void sendMessage(String message){
            this.kafkaTemplate.send("AWSKafkaTopic",message);
        }

Actual result->

在我的情况下，我尝试在新主题中生成消息，但auto.create.topics.enable在falseaws 代理中，因此更好地在现有主题上创建消息或auto.create.topics.enable将此属性设置为true并尝试。
