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)?
