需要关于Spring Boot Kafka Stream Binder应用程序错误的建议

濮阳赞
2023-03-14

我试图运行一个Spring boot Kafka流示例https://cloud.spring.io/spring-cloud-stream-binder-kafka/spring-cloud-stream-binder-kafka.html#_usage_2地点

我能够成功地构建它。但在运行时，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）。有人能帮忙找出代码中的问题吗？

ReplicateKafkaStreamApplication。Java语言

您需要使用匹配的spring版本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>

并从依赖项中删除相同的内容
