使用spring-cloud-stream发送rabbitmq消息时无法指定发送的RoutingKey

Question

我用的是3.1.3版本。以下配置后，'output-out-0.producer.bindingRoutingKey'不生效。当我发送消息时，路由键 = command_exchange_open 而不是：ORDER_PUSH

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-stream-binder-rabbit</artifactId>
</dependency>

spring:
  rabbitmq:
    addresses: amqp://sycx:sycx@192.168.1.204
  cloud:
    stream:
      rabbit:
        bindings:
          input-in-0:
            consumer:
              bindingRoutingKey: ORDER_PUSH
              exchangeType: direct
              queueNameGroupOnly: true
          output-out-0:
            producer:
              bindingRoutingKey: ORDER_PUSH
              queueNameGroupOnly: true
              bindQueue: false
      bindings:
        input-in-0:
          destination: command_exchange_open
          group: ORDER_END
        output-out-0:
          destination: command_exchange_open
          group: ORDER_END
    function:
      definition: input;output

生产者 属性 应该是 routing-key-expression: '''ORDER_PUSH''' 而不是 bindingRoutingKey。

          output-out-0:
            producer:
              bindingRoutingKey: ORDER_PUSH
              queueNameGroupOnly: true
              bindQueue: false

这些属性不适用于生产者（除非您设置了 required-groups）。
