Q1:Failed to start bean 'org.springframework.kafka.config.internalKafkaListenerEndpointRegistry'

A1:是因為沒有在注入時未對其進行配置導致，註冊參照如下

/**

@Configuration
@EnableKafka
public class kafkatemplateConfig {

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

    @Bean
    public KafkaListenerContainerFactory<ConcurrentMessageListenerContainer<String,String>> kafkaListenerContainerFactory(){
        ConcurrentKafkaListenerContainerFactory<String,String> factory = new ConcurrentKafkaListenerContainerFactory<>();
        factory.setConsumerFactory(consumerFactory());
        factory.setConcurrency(3);
        factory.getContainerProperties().setPollTimeout(5000);
        return factory;
    }

    @Bean
    public ConsumerFactory<String,String> consumerFactory(){
        return new DefaultKafkaConsumerFactory<>(consumerConfigs());
    }

    @Bean
    public Map<String,Object> consumerConfigs(){
        Map<String,Object> propsMap = new HashMap<>();
        propsMap.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG,this.bootstrapServers);
        propsMap.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG,false);//自行控制提交offset
        propsMap.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG,"100");//提交延遲毫秒數
        propsMap.put(ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG,"15000");//執行超時時間
        propsMap.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
        propsMap.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
        propsMap.put(ConsumerConfig.GROUP_ID_CONFIG,"dsafas");
        propsMap.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG,"latest");//開始消費位置
        return propsMap;
    }

    @Bean
    public Consumer listener(){
        return new Consumer();
    }
}

 Q2:a:Could not instantiate class org.springframework.kafka.support.serializer.JsonDeserializer

　　b:org.springframework.kafka.support.serializer.JsonDeserializer with modifiers "protected"

　　c:If the serializationyou can also enable trust all (*)   

A2:看下是因為要為監聽者得到的物件 在進行序列化與反序列化 要進行設定在上述配置類中如下兩列針對該問題

參考1    參考2

    propsMap.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
    propsMap.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);

Q3:java.lang.IllegalArgumentException: Magic v1 does not support record headers

　　A3:版本問題 我其實遇到時是用的 springboot.version: 2.1.0.RELEASE 部署的kafka元件版本為較新版kafka_2.11-2.1.0    與舊版kafka_2.12-0.10.2.1 最終將springboot.version換成1.5.10.RELEASE
