如何解决需要有关Spring Boot Kafka Stream Binder应用程序错误的建议
我试图从https://cloud.spring.io/spring-cloud-stream-binder-kafka/spring-cloud-stream-binder-kafka.html#_usage_2网站运行Spring boot Kafka Stream示例。
能够成功构建它。但是在运行它时出现如下所示的错误（ java.lang.IllegalStateException：org.springframework.cloud.stream.function.FunctionConfiguration 上的错误处理条件）。 谁能帮助找出代码中的问题？
ReplicateKafkaStreamApplication.java

}
}

解决方法
您需要使用匹配版本的spring才能正确加载依赖项
真正的错误是NoClassDefFoundError
删除依赖项部分中的所有版本，并更新您的父级以使用
<artifactId>spring-cloud-starter-stream-kafka</artifactId>
并从依赖项中删除
