我正在尝试通过sasl\u ssl协议和jaas config连接到kafka群集，如下所示：

spring:
  cloud:
    stream:
      bindings:
        binding-1:
          binder: kafka-1-with-ssl
          destination: <destination-1>
          content-type: text/plain
          group: <group-id-1>
          consumer:
            header-mode: headers
        binding-2:
          binder: kafka-2-with-ssl
          destination: <destination-2>
          content-type: text/plain
          group: <group-id-2>
          consumer:
            header-mode: headers

      binders:
        kafka-1-with-ssl:
          type: kafka
          defaultCandidate: false
          environment:
            spring:
              cloud:
                stream:
                  kafka:
                    binder: 
                      brokers: <broker-hostnames-1>
                      configuration:
                        ssl:
                          truststore:
                            location: <location-1>
                            password: <ts-password-1>
                            type: JKS
                      jaas:
                        loginModule: org.apache.kafka.common.security.scram.ScramLoginModule
                        options:
                          username: <username-1>
                          password: <password-1>

        kafka-2-with-ssl:
          type: kafka
          defaultCandidate: false
          environment:
            spring:
              cloud:
                stream:
                  kafka:
                    binder: 
                      brokers: <broker-hostnames-2>
                      configuration:
                        ssl:
                          truststore:
                            location: <location-2>
                            password: <ts-password-2>
                            type: JKS
                      jaas:
                        loginModule: org.apache.kafka.common.security.scram.ScramLoginModule
                        options:
                          username: <username-2>
                          password: <password-2>
      kafka:
        binder:
          configuration:
            security:
              protocol: SASL_SSL
            sasl:
              mechanism: SCRAM-SHA-256

上面的配置与springcloudstream的官方gitrepo上提供的示例配置是内联的。
在图书馆的gitrepo上提出的类似问题表示，它在最新版本中得到了修复，但看起来并非如此。获取以下错误：
springbootversion:2.2.8和SpringCloudStreamDependencies版本-horsham.sr6。

这让我觉得库没有正确地获取配置道具，因为 jaas.loginModule 指定为 ScramLoginModule 但它在使用 Krb5LoginModule 进行身份验证。
但是，令人吃惊的是，当按照以下方式进行配置时（区别在于最后一部分在binder的环境之外使用ssl凭据），它连接到全局ssl props（在binder的env之外）中指定的binder，并且默默地忽略另一个binder，而不显示任何错误日志。
说明绑定器的密码凭据 kafka-2-with-ssl 如果在全局ssl props中指定了，则将创建该绑定器，并且订阅该绑定器的绑定将开始使用事件。但这仅在需要创建单个绑定器时才有用。

向您保证ssl凭据没有问题。用ssl-kafka绑定器中的任何一个进行了认真的测试，成功地单独创建了。其目的是通过sasl\u ssl协议连接到多个kafka绑定器。提前谢谢。
