为什么 JLupin 存储队列无法访问任务？

Question

我在使用 JLupin 存储队列时遇到了问题。完成后检索任务时出现问题。JLupin 配置在 2 个集群上，每个集群 3 台服务器。Jlupin QueueMicroservice 安装在每个节点上。先感谢您。

您可能没有为您的 queueMicroservice 实例配置共享磁盘。默认情况下，“平台/存储”用作存储队列数据的位置。查看 JLupin 的文档以获取有关使用磁盘存储实现配置队列的更多详细信息。https://jlupin.io/documentation/jlupin-reactive-queues-16/page/storage-jlupin_disk.html
