Apache IGNITE高速缓存操作故障

Question

我已经使用Docker Hub的Docker Image安装了IGNITE。IGNITE服务器节点启动正确。但是我在尝试更新缓存时会得到以下例外：

[SEVERE][rest-#35%null%][GridCacheCommandHandler] Failed to execute cache command: GridRestCacheRequest [cacheName=null, cacheFlags=0, ttl=null, super=GridRestRequest [destId=null, clientId=466b7ff5-c303-452e-8f2d-97d59c753de5, addr=null, cmd=CACHE_PUT]]

有什么想法是什么问题？

Answer 1

您应该在开始使用它之前创建缓存。使用getorcreatecache方法。

您可以在DOC中阅读更多信息，并检查此示例，该示例使用缓存API。

另外，Apache Ignite中有很多例子。
