Question

我创建了一个带有消息过期args的队列，但是在启动服务器时出现以下错误。

[SimpleAsyncTaskExecutor-1] o.s.a.r.c.RabbitAdmin [RabbitAdmin.java:375] Auto-declaring a non-durable Queue (TEST_QUEUE). It will be redeclared if the broker stops and is restarted while the connection factory is alive, but all messages will be lost.
pool-1-thread-1] o.s.a.r.c.CachingConnectionFactory [CachingConnectionFactory.java:249] Channel shutdown: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'durable' for queue 'EXP_MSG' in vhost '/': received 'false' but current is 'true', class-id=50, method-id=10)
ERROR [SimpleAsyncTaskExecutor-1] o.s.a.r.l.SimpleMessageListenerContainer [SimpleMessageListenerContainer.java:914] Failed to check/redeclare auto-delete queue(s).

我使用Spring boot 1.2.8和Spring 4.2.5版本。

   @Bean
    Queue expiredMessageQueue() {
        Map args = new HashMap();
        args.put("x-message-ttl", 60000);
        return new Queue(expiredMessageQueue, false, false, false,args);
    }

不等价的arg＆＃39;耐用＆＃39;对于队列＆＃39; EXP_MSG＆＃39;在vhost＆＃39; /＆＃39;：收到＆＃39; false＆＃39;但目前是真的＆＃39;

这意味着RabbitMQ Broker上已经存在这样的队列，但具有不同的属性。

如果您想要更改它并通过应用程序重新创建，则应在开始应用程序之前首先从Broker中删除它。或者将所有选项与现有选项对齐。

这就像passiveDeclaration一样。监听器确实需要一个真正的队列来订阅，并且只有为什么要检查它是否存在于所需状态，尝试在监听器启动期间声明它。

使用args创建SpringAMQP队列
