所以我要把一个微服务从spring框架迁移到springboot2.3.10.release。但当我尝试创建集成测试并启动它时，出现了一个模糊的错误：

这是我的Kafka配置：

@EnableKafka
    @Configuration
    public class KafkaConfig {
      // Some Properties & Consumer Configurations

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

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

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

服务pom父级继承自版本为2.3.10.release的spring boot starter父级。jackson库版本也继承自父pom，我检查了所有jackson版本都使用2.11.4，没有冲突的依赖关系。当我运行应用程序时，kafkatemplate会正常示例化。它只在我开始集成测试时抛出这个错误。我错过了什么？有办法调试这个吗？
以下是我尝试过但失败的：
清除.m2目录
在父pom中显式声明jackson数据绑定版本
将JUnit4更改为JUnit5
升级maven-plugins至最新版本
将Spring Boot版本降低1
