我们正在使用Apache Ignite作为缓存来加速我们的授权和权限调用。在客户端加载应用程序时，应用程序会通过18次get调用命中Ignite缓存，在此期间，我们经常从Ignite获取缓存关闭异常。尽管我们一直试图使用大量调用来复制相同情况，但错误似乎每18次调用中有3-4次出现，而且当本地运行时也是如此。我们已经将所有推荐的配置应用于集群。
我们正在使用通过注解调用的简单缓存.get()和缓存.put()方法。
目前我们正在使用。

我们正在使用通过注解调用的简单缓存.get()和缓存.put()方法。
目前我们正在使用。
try {
cache.put(key, returnType.cast(result));
} catch (CacheException | org.hibernate.cache.CacheException e) {
if (e.getCause() instanceof IgniteClientDisconnectedException) {
IgniteClientDisconnectedException cause =(IgniteClientDisconnectedException)e.getCause();
cause.reconnectFuture().get(); // Wait for reconnection.
cache.put(key, returnType.cast(result));
addDiconnectCount();
LOGGER.error("Diconnection Reason Trace: ", e);
}
}
我们尝试使用以下方法解决错误，但我们无法找出频繁缓存重新连接的根本原因。我们在本地使用了4GB XMX，并且有大约86％未使用的堆内存以及在Ignite集群和客户端中几乎没有节点。
我们正在尝试存储以下类型的对象：
Map<String, Serializable>
map.put(String, String[]);
List<String>
