}

Declare a queue
Params:
queue – the name of the queue
durable – true if we are declaring a durable queue (the queue will survive a server restart)
exclusive – true if we are declaring an exclusive queue (restricted to this connection)
autoDelete – true if we are declaring an autodelete queue (server will delete it when no longer in use)
arguments – other properties (construction arguments) for the queue
Returns:
a declaration-confirm method to indicate the queue was successfully declared
Throws:
IOException – if an error is encountered

        中文注释：

queue：队列的名称。
durable：队列是否持久化，如果为true，rabbitmq服务重启该队列仍然存在。

exclusive：（独占）声明队列同一时间只能保证一个连接，且该队列只有被这一个连接使用。

autoDelete：自动删除的队列，当该队列没有任何的关联时，就会被自动删除。

arguments：扩展参数。
