Spring Cloud Streaming多个Kafka活页夹配置恢复为默认活页夹

Question

我有一个具有多个kafka活页夹配置的spring boot应用程序：

spring.cloud.stream:    
  bindings.publisher_input:
    destination: input_publisherUpdate
    group: dev
    binder: kafka2_binder

  bindings.publisher_output:
    destination: output_publisherUpdate
    producer.headerMode: raw
    binder: kafka1_binder

  binders:
    kafka1_binder:
      defaultCandidate: false
      type: kafka
      inheritEnvironment: false
      environment:
        spring.cloud.stream.kafka.binder:
          zkNodes: zk-b-1-vm:2181
          brokers: kafka-c2-01-vm:9092
        spring.cloud.stream.kafka.mode: raw
        spring.cloud.stream.default.consumer.headerMode: raw

   kafka2_binder:
      defaultCandidate: false
      type: kafka
      inheritEnvironment: false
      environment:
        spring.cloud.stream.kafka.binder:
          zkNodes: zk-stage-1:2181
          brokers: kafka-stage-1-broker:9092
        spring.cloud.stream.kafka.mode: raw
        spring.cloud.stream.default.consumer.headerMode: raw

如果我不包括defaultCandidate: false，它会抱怨找不到默认的资料夹。当我包含它时，出现以下错误-它似乎正在寻找一些默认的活页夹配置（localhost：2181） 关于我在这里缺少什么的任何想法？
