Spring kafka设置最大拉取数量

现在是服务器调用我的接口，然后我手动打开kafka监听，返回数据给接口，但是考虑到服务器 的性能，一次只希望消费比如10条左右，但是我设置了max-poll-records这个参数以后，还是会监听到所有的消息

List<String> dataList=new ArrayList<>();

    @Autowired
    private KafkaListenerEndpointRegistry registry;

    @Autowired
    private ConsumerFactory consumerFactory;

    @Bean
    public ConcurrentKafkaListenerContainerFactory delayContainerFactory() {
        ConcurrentKafkaListenerContainerFactory container = new ConcurrentKafkaListenerContainerFactory();
        container.setConsumerFactory(consumerFactory);
        //禁止自动启动
        container.setAutoStartup(false);
        return container;
    }

    @KafkaListener( topics = "topic.message1",containerFactory = "delayContainerFactory",id="KAFKA_ID")
    public void durableListener(String data) {
        //这里做数据持久化的操作
        log.info("topic.message receive : " + data);
        JSONObject obj = new JSONObject(data);
        String subject = (String) (obj.get("subject"));
        log.info(subject);

        dataList.add(subject);
    }


    public void startListener() {
        log.info("开启监听");
        //判断监听容器是否启动，未启动则将其启动
        if (!registry.getListenerContainer("KAFKA_ID").isRunning()) {
            registry.getListenerContainer("KAFKA_ID").start();
        }
        registry.getListenerContainer("KAFKA_ID").resume();
    }

    public void shutDownListener() {
        log.info("关闭监听");
        registry.getListenerContainer("KAFKA_ID").pause();
    }

    public List<String> receivedData(){
        return dataList;
    }

server:
    port: 8080
Spring:
    kafka:
        bootstrap-servers: 132.232.8.25:32091
        consumer:
            enable-auto-commit: true
            auto-commit-interval: 100ms
            auto-offset-reset: latest
            group-id: uap-message
            key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
            value-deserializer: org.apache.kafka.common.serialization.StringDeserializer
            max-poll-records: 1

我设置的最大是一条，但是消息传过来我还是能收到好几条，是什么原因

一次调用poll()操作时返回的最大记录数，默认值为500
把max-poll-records值改为2 试试
