ConfigurationProperties 的 RabbitListener 注释队列名称 [英] RabbitListener annotation queue name by ConfigurationProperties

问题描述

我已经通过 application.yaml 和 spring configurationProperties 配置了我的兔子属性.因此，当我配置交换、队列和绑定时，我可以使用我的属性的 getter

I have configured my rabbit properties via application.yaml and spring configurationProperties. Thus, when I configure exchanges, queues and bindings, I can use the getters of my properties

@Bean Binding binding(Queue queue, TopicExchange exchange) {
    return BindingBuilder.bind(queue).to(exchange).with(properties.getQueue());
}

@Bean Queue queue() {
    return new Queue(properties.getQueue(), true);
}

@Bean TopicExchange exchange() {
    return new TopicExchange(properties.getExchange());
}

但是，当我配置 @RabbitListener 以从队列中记录消息时，我必须使用完整的属性名称，如

However, when I configure a @RabbitListener to log the messages on from the queue, I have to use the full properties name like

 @RabbitListener(queues = "${some.long.path.to.the.queue.name}") 
 public void onMessage(
            final Message message, final Channel channel) throws Exception {
       log.info("receiving message: {}#{}", message, channel);
    }

我想避免这种容易出错的硬编码字符串，并参考 configurationProperties bean:

I want to avoid this error prone hard coded String and refer to the configurationProperties bean like:

@RabbitListener(queues = "${properties.getQueue()}") 

我有一个 类似的问题，其中使用了 bean 引用的 @EventListener "@bean.method()" 有帮助，但它在这里不起作用，bean 表达式只是被解释为队列名称，失败是因为队列 namde "@bean...." 不存在.

I had a similar issue once with @EventListener where using a bean reference "@bean.method()" helped, but it does not work here, the bean expression is just interpreted as queue name, which fails because a queue namde "@bean...." does not exist.

是否可以将 ConfigurationProperty-Beans 用于 RabbitListener 队列配置?

Is it possible to use ConfigurationProperty-Beans for RabbitListener queue configuration?

推荐答案

这样的事情对我有用，我只使用了 Bean 和 SpEL.

Something like this worked for me where I just used the Bean and SpEL.

@Autowired
Queue queue;

@RabbitListener(queues = "#{queue.getName()}")
