  Here is an example of providing a `BinderCustomizer` bean.
  
  [source, java]
  ----
  @Bean
  public BinderCustomizer binderCustomizer() {
      return (binder, binderName) -> {
          if (binder instanceof KafkaMessageChannelBinder) {
              ((KafkaMessageChannelBinder) binder).setRebalanceListener(/*...*/);
          }
          else if (binder instanceof KStreamBinder) {
              // ...
          }
          else if (binder instanceof RabbitMessageChannelBinder) {
              // ...
          }
      };
  }
  ----
  
  Note that, when there are more than one instance of the same type of the binder, the binder name can be used to filter customization.
