Spring 云 stream RabbitMQ 随机失败，出现队列 NOT_FOUND 错误

Question

我已经配置了 RabbitMQ 集群，我使用 Spring Cloud Stream 和这样的配置：Z7EAA993723E57B3BFC99923

import org.springframework.cloud.stream.annotation.Input;
import org.springframework.messaging.SubscribableChannel;

public interface FileChangedSink {
    String INPUT = "fileChanged";

    @Input(INPUT)
    SubscribableChannel fileChanged();
}

和 application.yml

spring:
  cloud:
    stream:
      bindings:
        fileChanged:
          destination: file.changed
          binder: stream_rabbit
          consumer:
            max-attempts: 1

      binders:
        stream_rabbit:
          type: rabbit
          environment:
            spring:
              rabbitmq:
                host: ${RABBITMQ_HOST}
                port: ${RABBITMQ_NODE_PORT_NUMBER}
                username: ${RABBITMQ_DEFAULT_USER}
                password: ${RABBITMQ_DEFAULT_PASS}
                virtual-host: ${RABBITMQ_DEFAULT_VHOST}

版本：

Spring Boot Version: 1.5.10.RELEASE
spring-cloud-starter-stream: 1.3.2.RELEASE
spring-cloud-starter-stream-rabbit: 1.3.3.RELEASE

通常这个配置工作正常，但最近我遇到了这样的异常：

注意：此错误是随机的，通常我的配置可以正常工作。

从错误中我可以理解在 stream 尝试连接到它之前没有创建队列。

所以我的问题是它是如何发生的以及我如何防止这种情况发生？

Answer 1

不再支持引导 1.5.x； 最后一个版本 1.5.22 于 8 月发布。

您需要将队列参数x-queue-master-locator设置为client-local以确保在应用程序连接到的节点上创建匿名队列。

从 spring-amqp 2.1 版开始（由 Spring Boot 2.1 和 binder 2.2 使用），这是由框架自动完成的。

在早期版本中，您可以使用代理上的策略为匿名队列设置主定位器。
