Spring XD，RabbitMq：失败的分区流部署

标签： rabbitmq spring-integration spring-xd

在将分区流部署到我们的XD容器中时，流失败了，我们可以在XD容器日志级别找到Amq问题。原因似乎来自XD源DLQ的创建：在队列创建过程中，Spring XD没有正确设置'x-dead-letter-exchange'？

Caused by: com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'x-dead-letter-exchange' for queue 'xdbus.partitioned.0-0' in vhost '/': received none but current is the value 'xdbus.DLX' of type 'longstr', class-id=50, method-id=10)

分区流功能实现

Spring XD guide中描述了此功能。 流定义比指南简单，我们已经定义了一个包含两个元素的流：一个接收器和一个用于检查行为的源; 

 time | log

当我们部署流时，我们设置了这种分区配置：

 module.time.producer.partitionKeyExpression=payload.charAt(payload.length()-1),module.log.count=3

所以，预期的结果是：

  • 为时间源部署1个实例，为日志接收器部署3个实例;
  • 在运行时，密钥表达式将用于通过日志实例路由消息。

我们的安装设置

  • Zookeeper安装在群集中。 （3个节点）
  • RabbitMq用作消息总线。 （2个节点）
  • Spring XD安装在群集中。 （3个节点）

注意：在XD级别，总线配置为在每个部署的XD“模块”之前创建DLQ。

有没有人有类似的问题？

任何想法都会受到欢迎。 感谢

答案 0 :(得分：1)

这是一个错误。

当使用分区流绑定生产者时，我们不会检查队列是否已经存在（就像使用非分区流一样）。

我打开了Touch Events not registering for HTML5 Canvas Authoring using Flash CC。

解决方法是在消费者端禁用AutoBindDLQ并使用策略手动配置死字法。
