How to handle when the BROKER rabbitMq is down in Spring cloud stream?

Question

我想了解我们该如何处理经纪人本身处于关闭状态的情况，这是RabbitMQ，我也不想尝试RETRY机制。相反，我想检查一下Spring Cloud流， 怎么回事？检测RabbitMQ是否关闭 ，根据这种情况，我需要推送消息。

private CachingConnectionFactory connectionFactory;

Call connectionFactory.createConnection().close() to verify that the broker is up. If it's not you'll catch an exception.

In general, this won't open a new connection, it will just check that the shared (or a cached) connection is available.
