Question

我正在尝试设置具有Spring Cloud Stream支持的RabbitMQ

我有几个消费者和生产者。生产者之一应将消息产生到同一RabbitMQ实例（以后可能是不同的物理实例）上的单独虚拟主机。

application.yaml

spring:
  cloud:
    stream:
      binders:
        binder1:
          type: rabbit
            defaultCandidate: false
            inheritEnvironment: false
          environment:
            spring:
              rabbitmq:
                host: localhost
                port: 5672
                virtual-host: virtual-host-1
                username: guest
                password: guest
        binder2:
          type: rabbit
            defaultCandidate: false
            inheritEnvironment: false
          environment:
            spring:
              rabbitmq:
                host: localhost
                port: 5672
                virtual-host: virtual-host-2
                username: guest
                password: guest
      bindings:
        test:
          binder: binder1
        coordinates:
          destination: coordinates
          binder: binder1
        events:
          destination: events
          binder: binder1
        events_output:
          destination: events
          binder: binder1
        tasks:
          destination: tasks
          binder: binder2

目标是绑定tasks应该使用虚拟主机virtual-host-2。其他绑定应使用虚拟主机virtual-host-1。

但是似乎忽略了binder值，并且在应用程序启动时使用默认设置考虑了默认rabbit活页夹。

我在调试运行时注意到它：

每个绑定上的binder值为NULL。尽管该值在属性中明确提供。

如果我将defaultCandidate中的任何活页夹设置为true，则该活页夹设置将替代默认设置。

配置不正确吗？

Answer 1

这是我不喜欢Yaml的原因之一。很难跟踪可能配置错误的内容。无论如何，这是我刚刚尝试的工作示例。

spring:
  cloud:
    stream:
      bindings:
        input:
          binder: rabbit1
          group: vhost1-group
          destination: vhost1-queue
        output:
          binder: rabbit2
          destination: vhost2-queue
      binders:
        rabbit1:
          type: rabbit
          environment:
            spring:
              rabbitmq:
                host: localhost
                virtual-host: vhost1
        rabbit2:
          type: rabbit
          environment:
            spring:
              rabbitmq:
                host: localhost
                virtual-host: vhost2

我刚刚复制/粘贴了您的配置；修复了一些缩进，对我来说效果很好...

spring:
  cloud:
    stream:
      binders:
        binder1:
          type: rabbit
          defaultCandidate: false
          inheritEnvironment: false
          environment:
            spring:
              rabbitmq:
                host: localhost
                port: 5672
                virtual-host: virtual-host-1
                username: guest
                password: guest
        binder2:
          type: rabbit
          defaultCandidate: false
          inheritEnvironment: false
          environment:
            spring:
              rabbitmq:
                host: localhost
                port: 5672
                virtual-host: virtual-host-2
                username: guest
                password: guest
      bindings:
        test:
          binder: binder1
        tasks:
          destination: tasks
          binder: binder2

@SpringBootApplication
@EnableBinding(Foo.class)
public class So56462671Application {

    public static void main(String[] args) {
        SpringApplication.run(So56462671Application.class, args);
    }

}

interface Foo {

    @Input
    MessageChannel test();

    @Input
    MessageChannel tasks();

}

和

      defaultCandidate: false
      inheritEnvironment: false

缩进不正确，但出现YAML解析错误。
