用kafka和spring boot传递消息时出错

我用的是Kafka，我要跑放法
Kafka是带有zookeeper的docker容器，我有一个主题叫updaterate
这是放方法运行的方法

@PutMapping("v1/branches/{branchId}/rateUpdate")
public ResponseEntity<Void> rateBranchUpdate(@RequestParam("rate") Double rate,@PathVariable Long branchId) throws JsonProcessingException {
    Map<String,String> map=new HashMap<String,String>();
    map.put("rate",rate.toString());
    map.put("branchId",branchId.toString());
    producer.produceUpdateRate(map);
    return ResponseEntity.noContent().headers(HeaderUtil.createEntityDeletionAlert(applicationName, true, ENTITY_NAME, branchId.toString())).build();

}

这位是制片人

public class BranchProducer {

    private static final String TOPIC = "updateRate";

    private static final String groupId="store-service";

   private KafkaTemplate<String, String> kafkaTemplate;

   private final BranchService branchService;

    public BranchProducer(BranchService branchService,KafkaTemplate<String, String> kafkaTemplate) {
        this.branchService = branchService;
       this.kafkaTemplate=kafkaTemplate;
    }

    public void produceUpdateRate(Map<String,String> rate) throws JsonProcessingException {
        ObjectMapper mapper = new ObjectMapper();
        kafkaTemplate.send(TOPIC,mapper.writeValueAsString(rate));
    }
}

这就是消费者

@Component
public class BranchConsumer {

    private final Logger log = LoggerFactory.getLogger(BranchService.class);
    private final BranchService branchService;
    private static final String TOPIC = "updateRate";
    private static final String groupId="store-service";
    public BranchConsumer(BranchService branchService) {
        this.branchService = branchService;
    }

   @KafkaListener(topics = TOPIC ,groupId = groupId)
    public void processUpdateRating(@Payload Map<String,String> rate)
    {
        branchService.rateUpdate(Double.parseDouble(rate.get("rate")),Long.parseLong(rate.get("branchId")));
        log.debug("done update in queue");

    }

}

但当运行代码生产者不发送消息给消费者，我有这个错误

ProcessUpdateing中的这个错误接受字符串参数，但我有map参数解决方案只是将map改为string
@kafkalistener（topics=topic，groupid=groupid）public void processupdateing（string rate）{log.debag（rate）；
}
