我试图将kafka集成到项目中的一个服务中，但是它已经集成在另一个服务中，所以我自然地尝试使用使用这两个依赖项的相同kafka版本:
implementation 'org.springframework.integration:spring-integration-kafka:3.1.5.RELEASE'
implementation 'org.springframework.kafka:spring-kafka:2.2.15.RELEASE'
但是我得到的是这个错误:
Error creating bean with name 'kafkaProducerFactory' defined in class path resource [org/springframework/boot/autoconfigure/kafka/KafkaAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.kafka.core.ProducerFactory]: Factory method 'kafkaProducerFactory' threw exception; nested exception is java.lang.NoClassDefFoundError: org/springframework/kafka/core/MicrometerProducerListener
得到之后，我查找了kafka spring兼容性矩阵(https://spring.io/projects/spring-kafka/#quick-start)，并相应地更新了我的项目到
implementation 'org.springframework.kafka:spring-kafka:2.7.14'
服务工作，所以我尝试升级相同的依赖，但最终得到错误:
Error creating bean with name 'org.springframework.kafka.config.internalKafkaListenerAnnotationProcessor': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.kafka.annotation.KafkaListenerAnnotationBeanPostProcessor]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org/springframework/core/log/LogAccessor
这对我来说真的很奇怪，因为两个服务上的spring版本是一样的，我知道我在这些服务上使用不同版本的kafka依赖，但是也许有人能给我一些清晰的问题，为什么会发生这种情况，为什么我不能只使用兼容性矩阵?(也许这只是一个错误的矩阵?)

您的Spring Framework版本(5.1.9.RELEASE)太旧;一般来说，最好只指定Boot版本，它会使用它的依赖管理功能引入所有依赖的正确版本。
同样，spring-integration-kafka必须是5.5。X(根据该矩阵)
