spring rabbit amqp @RabbitListener配置min和max的消费者数量 [英] spring rabbit amqp @RabbitListener configure min and max number of consumers

问题描述

我正在使用spring amqp rabbit @RabbitListener annotation
from：artifact spring-rabbit-1.7.1.RELEASE
我想知道是否有办法为每个队列配置多少个消费者？
我一直在挖掘文档并发现什么都没有，有没有办法在相关容器中为每个队列配置多少消费者？
提前致谢。

解决方案

通过容器工厂bean，如文档所示。

  @Bean 
 public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory（）{
 SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory（）; 
 factory.setConnectionFactory（connectionFactory（））; 
 factory.setConcurrentConsumers（3）; 
 factory.setMaxConcurrentConsumers（10）; 
返厂; 
} 
  

如果您使用Spring Boot，它会为您创建工厂bean，可以使用属性配置它们。

如果你想要固定数量的消费者，只需省略 max 。

如果您想为每个监听器设置不同的设置，则每组设置需要不同的工厂。然后，您将在其 containerFactory 属性中为 @RabbitListener 引用特定容器工厂。

I am using spring amqp rabbit @RabbitListener annotation from : artifact spring-rabbit-1.7.1.RELEASE I wonder if there is a way to configure for each queue the number of consumers ? I have been digging in the documentation and found nothing yet , is there a way to configure in the related container for each queue the number of consumers ? Thanks in advance.

解决方案

Configure the concurrency via the container factory bean as shown in the documentation.

@Bean
public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory() {
    SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
    factory.setConnectionFactory(connectionFactory());
    factory.setConcurrentConsumers(3);
    factory.setMaxConcurrentConsumers(10);
    return factory;
}

If you are using Spring Boot, which creates the factory bean for you, you can configure them using properties.

If you want a fixed number of consumers, just omit the max.

If you want different settings for each listener, you need a different factory for each set of settings. You would then reference the particular container factory for a @RabbitListener in its containerFactory property.
