java - 常规和 Spring 抽象的 Ignite 事务在手动重新连接后以 IllegalStateException 失败，clientReconnectDisabled 为 true

问题描述

我们正在运行 2.4 版并使用 Spring IgniteSpringBean、SpringTransactionManager和Spring Data存储库进行集群和事务缓存访问。

由于我们遇到了很多与 IgniteClientDisconnectedException 相关的问题，因此我正在编写一个手动分段解析器（通过禁用自动客户端重新连接并将 clientReconnectDisabled 设置为 true）来检测这种情况（使用定期运行的简单缓存查询）并启动断开连接通过IgniteSpringBean#close然后按照此处所述重新连接

我在缓存访问方面遇到了其他问题，我按照此处所述解决了这些问题

但问题是，每当我尝试使用 spring 事务注释方法时，它都无法创建一个带有 IllegalStateException 的事务，该异常提到网格处于无效状态。

我怀疑它与我之前遇到的相同问题（上面引用过）引用过时的引用，并且可能需要通过更新 SpringTransactionManager 中的内核引用来在代码中处理它。我正在尝试该修复程序，如果可行，将进行更新。

同时，如果有人有更简单/更快的修复方法/建议，请分享。

下面是例外，

解决方案

重新连接后关闭缓存在 2.5 版本中已修复（ https://issues.apache.org/jira/browse/IGNITE-2766）。

据我了解，您想创建一个新的 ignite 实例并将其用于 SpringTransactionManager。我认为这不是正确的方法，因为例如在 IgniteRepositoryImpl#cache 中有缓存实例也需要重新初始化。

我建议使用 IgniteClientDisconnectedException#reconnectFuture() 方法，该方法返回将在重新连接发生时完成的未来。因此，您可以阻止客户端并等到将来解决并且客户端变为活动状态。例如：

public void checkAndReconnect(){
    try{
        // make ignite query
    }catch(IgniteClientDisconnectedException ex){
       ex.reconnectFuture().get();
    }
}

希望它有助于解决连接问题。
