目前我们正在使用Ignite 2.1和Spring Data Ignite Repository。我有一个服务器节点和一个带有一个缓存“TestCache”的客户端节点。当客户端连接到服务器，并且服务器节点关闭时，它将断开连接。当服务器节点重新启动时，客户机节点将重新连接回来。
但是，当它连接回来时，不再可以访问缓存“TestCache”，但出现以下异常：

尝试过以下方法，但似乎没有连接回缓存。对以下问题有任何想法吗？
ig.events().localListen(new IgnitePredicate<Event>() {
@Override public boolean apply(Event event) {
switch (event.type()) {
case EventType.EVT_CLIENT_NODE_RECONNECTED:
logger.info("Ignite Client reconnected!");
Runnable task = () -> {
ig.getOrCreateCache(spaCacheName);
logger.info("getOrCreateCache after reconnected");
};
Thread thread = new Thread(task);
thread.start();
}
return true;
}
}, EventType.EVT_CLIENT_NODE_DISCONNECTED, EventType.EVT_CLIENT_NODE_RECONNECTED);
提前致谢〜
我看到有关此问题的一些信息： How to restore cache after ignite server reconnected https://issues.apache.org/jira/browse/IGNITE-5789
答案 0 :(得分：3)
是的，您正确发现了与此问题相关的问题：https://issues.apache.org/jira/browse/IGNITE-5789
重新启动后，服务器节点（显然）没有任何有关缓存在停止之前启动的信息。同时，如果客户端重新连接EVT_CLIENT_NODE_RECONNECTED事件，则它不会再次创建缓存，因为它认为它已重新连接到已创建此缓存的同一群集。
作为一种解决方法，您可以重新启动客户端节点，它将在正常重新启动后再次创建缓存。
