崩溃rabbitmq后，我使用以下命令再次重新启动：

sudo service rabbitmq-server restart

一旦rabbitmq重新启动，我就失去了所有队列。我的队列耐久性是持久的，消息传递模式是非持久的

有什么方法可以恢复队列中的消息吗？它拥有正在处理的非常重要的用户数据。

没有。非持久性意味着它们在RAM中，而不是存储在磁盘上

一般性注释-RabbitMQ不是数据库。即使您已将队列设置为持久性，但期望消息代理可靠地处理200000条消息的临时存储也是疯狂的。系统的设计应确保代理是任务之间的缓冲区，平均队列长度为零。如果您发现了如此大的数量，要么加快处理速度，要么将其存储在一个数据库中，该数据库设计为能够在偶尔的重启中存活下来，而不会产生什么后果
