Rabbitmq + Spring Boot +消费者在处理一条消息后闲置15分钟

Question

我们使用Spring Boot（1.5）和集成来连接到Rabbit MQ作为PCF上的服务

设置的属性-并发= 15-maxConcurrency = 25-默认预取和txSize。

消息的处理方式。

1. 队列在不到1秒的时间内收到了26条消息。
2. 下一分钟有15位消费者开始和完成。
3. 每个消费者花费的平均时间约为30秒。
4. 很少有消费者花费少于15秒的时间。
5. 正如每个使用者确认的那样，来自就绪的新消息（第16条，第17条消息）在Rabbit MQ上未被确认。

到目前为止，由于我假设随着旧消息的确认，正在处理新消息。 但是随着新消息变得在RabbitMQ上没有得到确认，任何消费者都不会处理它们。 消费者陷入困境，无所事事。

1. 这将继续，并且所有就绪状态消息都将变为未确认状态，并停留在此状态而没有任何活动。
2. 它们都在大约15分钟后恢复。

我总是看到这种行为。

有指导吗？

这是执行兔子MQ接线的代码，中间的MessageHandler具有连接到大数据并进行一些查询的代码。

Answer 1

目前尚不清楚为什么会看到这种行为。 在大多数情况下（以我的经验），此类问题是由用户代码中的侦听器线程“卡住”引起的。 使用者线程不可能以这种方式“空闲”。 而且无论如何，它不会在15分钟后重新启动。

下一步（对我来说）将是执行线程转储以查看线程在做什么。 如果您不能使用jstack或VisualVM，则Boot提供了/dump端点来执行此操作。
