那么，在生产环境中使用ignite cluster时，如何处理关键故障呢 您的Ignite缓存创建配置错误。正确检查缓存配置。请参阅此链接 如果只需要将数据存储在缓存中，可以使用以下配置
CacheConfiguration<Long, User> cacheCfg = new CacheConfiguration<>("QQ");
cacheCfg.setCacheMode(CacheMode.PARTITIONED);
IgniteCache<Long, User> cache = ignite.getOrCreateCache(cacheCfg);
其中CacheStore是用户定义类，具有第三方数据操作指令我想您可以通过扩展AbstractFailureHandler来编写自己的处理程序。是的，这可能是一个解决方案。我知道配置是配置，但我想说的是如何处理此错误。因为我想在生产环境中使用ignite，如果有人编写这样的代码，集群将崩溃，其他人将丢失他们的数据。很难确定所有人都会做正确的事情。这是你在问题中给出的完整配置吗？如果是，则此配置即使在本地环境中也不应工作。因为无论何时将setReadThrough或setWriteThrough属性设置为true，都需要添加其CacheStoreFactory。
cacheCfg.setReadThrough(true);
cacheCfg.setCacheStoreFactory(FactoryBuilder.factoryOf(CacheStore.class));
