NoSuchMethodError when trying to map Kafka binder to input method-CodePudding

The following is prompted in console when trying to launch a spring cloud streams project with the Kafka binder active:

org.springframework.context.ApplicationContextException: Failed to start bean 'inputBindingLifecycle';
Caused by: java.lang.NoSuchMethodError: java.util.List.of(Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)Ljava/util/List;

My input method goes as follows using Spring Cloud functions:

    @Bean
    public Function<Message<String>, byte[]> exec() {
        return input -> ...

Now, having Kafka in place, my .properties file looks as follows:

spring.cloud.stream.function.bindings.exec-in-0=in
spring.cloud.stream.bindings.in.destination=topic-0
spring.cloud.stream.function.bindings.exec-out-0=out
spring.cloud.stream.bindings.out.destination=topic-1

spring.cloud.stream.bindings.in.binder=kafka
spring.cloud.stream.kafka.bindings.in.consumer.configuration.value.deserializer=org.apache.kafka.common.serialization.StringDeserializer

spring.cloud.stream.bindings.out.binder=kafka
spring.cloud.stream.kafka.bindings.out.producer.configuration.value.serializer=org.apache.kafka.common.serialization.ByteArraySerializer

Am I missing any configs for the input method? Should that method be different for Kafka (already tested this with PubSub and it works)?

CodePudding user response：

The error in your stack trace gives us a clue that you are facing this problem: https://github.com/spring-projects/spring-integration/issues/3761.

So, or upgrade to the latest Spring Cloud Stream: https://spring.io/projects/spring-cloud-stream#learn

Or to the latest Spring Integration: https://spring.io/projects/spring-integration#learn

Or just use Java > 8 !
