一个消费者的双重连接
Double connections for one consumer
我是 RabbitMQ 的新用户,我真的很喜欢它,但我有一个问题(它不会抛出任何错误,它不会影响任何东西,除了我的思想......)。
每次我 运行 一个消费者,它都会创建 2 个连接。我找不到原因所以我请求你的帮助。
我正在使用 Spring-Boot 和 Spring AMQP(可能是因为 Spring ...)
这是代码:
接收器-context.xml
<?xml version="1.0" encoding="UTF-8"?>

System.out.println("Waiting for message");
}
@Override

super.finalize();
this.context.close();
}
public static void main(String[] args) {

}
}

public void receiveMessage(String message) {
System.out.println("Message received : " + message);
}
}
这是开头的日志(注意带有双“*”的行):

这里是双连接:
如果我停止客户端,它会关闭两者(这就是为什么我确定它是同一消费者的双重连接)。
如果您需要更多信息,请在这里提问,我会尽快回复。
感谢大家的帮助。
答案很简单:我在同一个应用程序中创建了 2 个上下文。
new AnnotationConfigApplicationContext(AMQPPoCReceiverApplication.class);
和
SpringApplication.run(AMQPPoCReceiverApplication.class, args);
只需创建一个即可完成!
