spring-boot - Rabbit 监听器注释从 yaml 中获取队列名称

Question

我目前将我的兔子监听器注释设置为:

@RabbitListener(queues = "my-queue")

是否无法从我的 yaml 文件中提取队列名称。我想这样做的原因是，我可以将我的队列更改为我的集成测试的测试队列，只需更改 yaml 文件中的队列名称。看来注释必须接受一个常量字符串，有没有办法解决这个问题？谢谢，

是的，它叫properties place holder并且可以这样做:

@RabbitListener(queues = "${myQueue.property}")

哪里 myQueue.property完全在您的 yaml 中声明。

The argument name, value, and type can be property placeholders (${...}) or SpEL expressions (#{...}). The name must resolve to a String; the expression for type must resolve to a Class or the fully-qualified name of a class. The value must resolve to something that can be converted by the DefaultConversionService to the type (such as the x-message-ttl in the above example).
