Spring RabbitTemplate - 如何在发送时自动创建队列

问题描述

我将 RabbitMQ 与 Spring 的 RabbitTemplate 一起使用.

I am using RabbitMQ together with Spring's RabbitTemplate.

当使用模板发送方法向队列发送消息时，我希望队列不存在时自动创建/声明.

When sending messages to queues using the template send methods, I want the queue to automatically be created/declared if it is not already exists.

这非常重要，因为根据我们的业务逻辑，队列名称是在运行时生成的，我无法提前声明它们.

It is very important since according to our business logic queue names are generated on run-time and I cannot declare them in advance.

之前我们使用 JmsTemplate 并且任何发送或接收的调用都会自动创建队列.

Previously we have used JmsTemplate and any call to send or receive automatically created the queue.

推荐答案

是的，你可以使用 RabbitAdmin 和 admin.getQueueProperties() 来查看队列是否存在和 admin.declareQueue(new Queue(...)) 添加队列.您可能应该跟踪您已经检查/创建了哪些，以避免每次发送的开销.

Yes, you can use a RabbitAdmin and admin.getQueueProperties() to see if the queue exists and admin.declareQueue(new Queue(...)) to add a queue. You should probably keep track of which one's you've already checked/created in order to avoid the overhead on every send.

您还可以使用管理员添加交换并将队列绑定到它们.

You can also add exchanges and bind queues to them with the admin.
