问如何在春季Kafka消费前对Kafka消息进行过滤

EN

consumerRecord.key() // will return key of message
consumerRecord.value() // will return the message

 @Bean(name = "kafkaListenerContainerFactory")
public ConcurrentKafkaListenerContainerFactory<String, String> kafkaListenerContainerFactory() {
    ConcurrentKafkaListenerContainerFactory<String, String> factory = new ConcurrentKafkaListenerContainerFactory<>();
    factory.setConcurrency(Integer.parseInt(threads));
    factory.setBatchListener(true);
    factory.setConsumerFactory(kafkaConsumerFactory());
    factory.getContainerProperties().setPollTimeout(Long.parseLong(pollTimeout));
    factory.getContainerProperties().setAckMode(AbstractMessageListenerContainer.AckMode.BATCH);

    if(true) {
        factory.setRecordFilterStrategy(new RecordFilterStrategy<String, String>() {

            @Override
            public boolean filter(ConsumerRecord<String, String> consumerRecord) {
                if(consumerRecord.key().equals("ETEST")) {
                return false;
                }
            else {
                return true;
                 }
            }   
        });
    }

    return factory;
}
