如何在 Spring 云 Stream 中使用 2 个 Azure 事件中心

Question

I want to consume messages from following 2 connection strings

Endpoint=sb://region1.servicebus.windows.net/;SharedAccessKeyName=abc;SharedAccessKey=123;EntityPath=my-request Endpoint=sb://region2.servicebus.windows.net/;SharedAccessKeyName=def;SharedAccessKey=456;EntityPath=my-request

It is very simple to use Java API

EventHubConsumerAsyncClient client = new EventHubClientBuilder()
                        .connectionString("Endpoint=sb://region1.servicebus.windows.net/;SharedAccessKeyName=abc;SharedAccessKey=123;EntityPath=my-request")
                        .buildAsyncConsumerClient();

However, how to make this work in yaml file using Spring Cloud Stream (equivalent to the Java code above)?Tried all tutorials found online and none of them works.

spring:
      cloud:
        stream:
          function:
            definition: consumeRegion1;consumeRegion2
          bindings:
            consumeRegion1-in-0:
              destination: my-request
              binder: eventhub1
            consumeRegion2-in-0:
              destination: my-request
              binder: eventhub2
          binders:
            eventhub1:
              type: eventhub
              default-candidate: false
              environment:
                spring:
                  cloud:
                    azure:
                      eventhub:
                        connection-string: Endpoint=sb://region1.servicebus.windows.net/;SharedAccessKeyName=abc;SharedAccessKey=123;EntityPath=my-request
            eventhub2:
              type: eventhub
              default-candidate: false
              environment:
                spring:
                  cloud:
                    azure:
                      eventhub:
                        connection-string: Endpoint=sb://region2.servicebus.windows.net/;SharedAccessKeyName=def;SharedAccessKey=456;EntityPath=my-request

    @Bean
    public Consumer<Message<String>> consumeRegion1() {
        return message -> {
            System.out.printf(message.getPayload());
        };
    }

    @Bean
    public Consumer<Message<String>> consumeRegion2() {
        return message -> {
            System.out.printf(message.getPayload());
        };
    }

Answer 1

As log says use spring.cloud.function.definition property. Refer to docs
