RabbitMQ无法声明队列,并且侦听器无法在服务器上获取队列

标签: spring-boot rabbitmq message-queue spring-amqp spring-rabbitmq

我有 spring boot rabbitmq 应用程序,我必须将Employee对象发送到队列。然后我设置了一个监听器应用程序。对employee对象进行一些处理,并将此对象放入回调队列。

为此,我在我的应用程序中创建了以下对象。

  1. 创建 ConnectionFactory
  2. 使用 ConnectionFactory 创建 RabbitAdmin 对象。
  3. 请求队列。
  4. 回调队列。
  5. 直接交流。
  6. 请求队列绑定。
  7. 回调队列绑定。
  8. 的MessageConverter。
  9. RabbitTemplate对象。
  10. 最后是 SimpleMessageListenerContainer 的对象。
  11. 我的应用程序文件如下所示。

    application.properties

    spring.rabbitmq.host=localhost
    spring.rabbitmq.port=5672
    spring.rabbitmq.username=guest
    spring.rabbitmq.password=guest

    有人可以帮我解决我的问题吗?根据我的理解,当创建 SimpleMessageListenerContainer 的对象时,不会在rabbitmq服务器上创建回调队列。我尝试使用 RabbitAdmin 对象声明队列,但随后执行停止,没有任何进展。当我在默认虚拟主机中声明队列时,此问题不存在。但当我添加虚拟主机 foo 时,所有突然停止工作。您可以使用上面的代码复制此问题。我已经粘贴了所有代码。请告诉我是否还有其他事情要发布。

    有趣的是,即使我收到此异常,我的应用程序也已启动并运行。这意味着我的回调队列以某种方式被创建, SimpleMessageListenerContainer 的对象获得队列。我在某处读到,当创建队列时,我的 SimpleMessageListenerContainer 对象将监听它。

    请帮我解决这个问题。

答案 0 :(得分:2)

  

当我在默认虚拟主机中声明队列时,此问题不存在。但当我添加虚拟主机foo时,所有突然停止工作。

访问新虚拟主机的用户是否拥有configure权限?声明队列需要配置权限。

需要RabbitAdmin来声明队列/绑定;容器只执行被动声明以检查队列是否存在。

修改

container.start();

您不能在bean定义中start()容器autoStartUp。如果容器的trueSpacePhoto(默认值),应用程序上下文将在完全构建应用程序上下文后执行此操作。

从您的日志中可以清楚地看到容器启动太早 - 在声明其他bean(管理员,队列等)之前。
