Question

我正在使用spring-rabbit-1.7.1库供Java中的Rabbitmq使用者使用。我有7个使用者在运行，相同的服务器也是生产者。突然，消费者停止使用消息，并在我重新启动消息时恢复了消息。没有例外，线程转储如下：

随着队列中消息数量的增加，生产者工作正常。

当前的1.7.x版本是1.7.10。

确保基础RabbitMQ enableAutoRecovery中的false是ConnectionFactory。在4.0.x客户端中默认设置为true； Spring AMQP不需要客户端自动恢复，因为它从1.0.0开始具有自己的恢复机制。

已解决了一些错误，以解决大多数兼容性问题，但应将其设置为false。除非您提供预先配置的RabbitMQ ConnectionFactory-例如PCF上的spring-cloud-connectors，否则Spring AMQP将自动禁用它。

此问题已在连接器的2.0.3版本中修复。

RabbitMQ spring JAVA客户端停止使用消息，重新启动后恢复运行
