Rabbit MQ：PrefetchCount和连续主动触发器之间的区别？

Question

我正在使用Sprint配置RabbitMQ的PrefetchCount和连续活动触发器参数。

请，您能告诉我这两个参数之间的区别吗？

@Bean
    public SimpleRabbitListenerContainerFactory rabbitListenerReceiveError(ConnectionFactory connectionFactory) {
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory);
        int concurrentConsumers = Integer.parseInt(PropertiesLoader.getProperty("queue.receive_error.concurrent-consumers"));
        int maxConcurrentConsumers = Integer.parseInt(PropertiesLoader.getProperty("queue.receive_error.max-concurrent-consumers"));
        int consecutiveActiveTrigger = Integer.parseInt(PropertiesLoader.getProperty("queue.receive_error.consecutive-active-trigger"));
        int prefectCount = Integer.parseInt(PropertiesLoader.getProperty("queue.receive_error.prefetch_count"));

        factory.setPrefetchCount(prefectCount);
        factory.setConcurrentConsumers(concurrentConsumers);
        factory.setMaxConcurrentConsumers(maxConcurrentConsumers);
        factory.setConsecutiveActiveTrigger(consecutiveActiveTrigger);
        return factory;
    }

.properties文件中的信息

queue.receive_error.name=queue.receive_error
queue.receive_error.exchange=auto.receive_error
queue.receive_error.routingKey=receive_error
queue.receive_error.concurrent-consumers=1
queue.receive_error.max-concurrent-consumers=30
queue.receive_error.consecutive-active-trigger=5
queue.receive_error.prefetch_count=1
