java - value.serializer 出错（Docker 中的 Spring Boot 和 Kafka）

Question

如果我从 fatjar 运行 spring，它会使用 spring 序列化程序，它可以工作（在生产者设置，包中规定org.springframework.kafka.support.serializer.JsonSerializer），消息序列化没有错误，但是如果你尝试在容器中运行 spring boot，由于某种原因设置不适用，标准com.fasterxml.jackson.databind.JsonSerializer有效，为什么会这样？

import org.springframework.kafka.support.serializer.JsonSerializer;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

@Configuration
public class KafkaProducerConfig {

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

    @Value("${spring.kafka.producer.client-id}")
    private String kafkaProducerId;

    @Bean
    public Map<String, Object> producerConfigs() {
        Map<String, Object> props = new HashMap<>();
        props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, kafkaServer);
        props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, LongSerializer.class);
        props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, JsonSerializer.class);
        props.put(ProducerConfig.CLIENT_ID_CONFIG, kafkaProducerId);
        return props;
    }

登录码头：

value.serializer = class com.fasterxml.jackson.databind.JsonSerializer

无法实例化类com.fasterxml.jackson.databind.JsonSerializer
