在加载数据的时候,报错
但是再run一次的时候,错误又消失了

参考代码 createCache
private GridCacheContext createCache(CacheConfiguration<?, ?> cfg,
CacheGroupContext grp,
@Nullable CachePluginManager pluginMgr,
DynamicCacheDescriptor desc,
AffinityTopologyVersion locStartTopVer,
CacheObjectContext cacheObjCtx,
boolean affNode,
boolean updatesAllowed,
boolean disabledAfterStart)
throws IgniteCheckedException {
assert cfg != null;
if (cfg.getCacheStoreFactory() instanceof GridCacheLoaderWriterStoreFactory) {
GridCacheLoaderWriterStoreFactory factory = (GridCacheLoaderWriterStoreFactory)cfg.getCacheStoreFactory();
prepare(cfg, factory.loaderFactory(), false);
prepare(cfg, factory.writerFactory(), false);
}
else
prepare(cfg, cfg.getCacheStoreFactory(), false);
CacheStore cfgStore = cfg.getCacheStoreFactory() != null ? cfg.getCacheStoreFactory().create() : null;
//此处省略后面N行这个代码是在客户端创建cache,并且会判断cacheStoreFactory
通过debug代码,发现执行到这一块的时候,拿到了server端的已经创建的path,并且这个path是有cacheStoreFactory的
但是我本地的客户端把 jdbcSource给删除掉了,导致无法创建基于数据库的cacheStore
这说明客户端的cache也需要跟服务端一样的cache store配置
检查代码可以发现, 这个报错发生在
if (appCtx == null)
throw new IgniteException("Spring application context resource is not injected.");这个不是因为拿不到bean,而且appCtx就没有, 需要寻找这个值是在哪里初始化的?
这个值是通过调用如下方法拿到的
List<DynamicCacheDescriptor> startDescs = clientCachesToStart(msg.requestId(), msg.startRequests());
发现一个奇怪的现象, 初次重启集群,然后直接运行刚才的客户端程序就不报错
有3个步骤,
第一步:启动集群
第二步:使用jdbc方式创建表插入数据
第三步:使用function方式创建jdbcStore,从数据库load数据
如果按这3步顺序执行是没有问题的, 执行完后,再去执行第二步就报错了.
也就是说jdbcStore创建完成后,再想用客户端调用,也得有jdbcStore的初始化
需要分析一下这种不同的方式会有什么问题?
未完待续
