我尝试使用springcloudkafka活页夹创建一个简单的pub-sub应用程序。但是，我无法在application.yml中设置序列化程序、反序列化程序属性以及其他生产者和使用者属性。我总是得到序列化/反序列化错误。甚至kafka在springboot项目中的日志也显示生产者和消费者仍然通过realyserializer配置用户。下面是代码示例。

处理器.java

public interface Processor {
    String INPUT="k-msg-source";
    String OUTPUT="k-msg-sink";
    @Input(INPUT)
    SubscribableChannel input();
    @Output(OUTPUT)
    MessageChannel output();
}

克雷斯特. java
@restcontroller公共类krest{

@Autowired
private Processor processor;
@GetMapping("/send")
public ResponseEntity<Void> send(@RequestParam("key")String key, @RequestParam("msg") String text){
    processor.input().send(MessageBuilder.withPayload(Message.builder().text(text).build()).setHeader(KafkaHeaders.MESSAGE_KEY, key).build());
    return ResponseEntity.ok().build();
}

}
消息.java

@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
public class Message {
    private String text;
}

最后是application.yml

spring:
  cloud:
    stream:
      bindings:
        k-msg-source:
          binder: kafka
          content-type: application/json
          destination: topic.kp.msg
          group: kp.msg.source
        k-msg-sink:
          binder: kafka
          content-type: application/json
          destination: topic.kp.msg
          group: kp.msg.sink
          producer:
            partition-count: 10
      binders:
        kafka:
          type: kafka
          environment:
            spring.cloud.stream.kafka.binder:
              brokers: localhost:9092
              configuration:
                value.serde: JsonSerde
                key.serde: StringSerde
              producer:
                value.serde: JsonSerde
                key.serde: StringSerde
              replication-factor: 1
