尝试使用spring-cloud-stream-binder-kstream 1.3.0.RELEASE版本

配置类：

@Configuration
@EnableBinding(KStreamProcessor.class)
public class KafkaProcessorConfiguration {


    @StreamListener(value = "input")
    @SendTo("output")
    public KStream<?, String> splitStrings(KStream<?, String> input) {
        input.print();
        System.out.println("PROCESSOR WITH INPUT "+input.toString());
        return input
                .flatMapValues(value -> Arrays.asList(value.toLowerCase().split("\\W+")));
    }
}

application.properties：

spring.cloud.stream.bindings.input.destination=kafka-kstream-source-output
spring.cloud.stream.bindings.output.destination=kafka-kstream-processor-output

P.S：注意同样的事情适用于此repo中共享的1.0.0.BUILD-SNAPSHOT https://github.com/mbogoevici/spring-cloud-stream-binder-kstream

=================================

更新：

按建议删除了devtools依赖项。

当然看起来像依赖版本不匹配。因此共享依赖树以供参考。

Answer 1

您是否有特殊原因在应用程序中使用devtools工件？你可以删除它并再试一次吗？似乎可能存在一些错误，一些代理如何在幕后工作。我们正在进一步研究这个问题。

您可能希望将所有spring cloud stream个依赖关系带到1.3.0行。

你能在GitHub上提供一个简单的示例应用程序，我们可以在那里重现这个问题吗？

我通过将所有scst版本升级到1.3来运行示例应用程序，但我没有得到您获得的异常。不要使用弹簧云BOM，请尝试使用：
