java - 常规和 Spring 抽象的 Ignite 事务失败，并在手动重新连接后出现 IllegalStateException，并将 clientReconnectDisabled 设置为 true

Question

我们正在运行版本 2.4 并使用 Spring IgniteSpringBean , SpringTransactionManager & Spring Data用于集群和事务缓存访问的存储库。

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)&通过 IgniteSpringBean#close 发起断开连接然后按照描述重新连接 here

我在缓存访问方面遇到了其他问题，已按照描述解决了 here

但问题是，每当我尝试使用 Spring 事务注释方法时，它都会无法创建事务，并出现 IllegalStateException 提到网格处于无效状态。

我怀疑这又是我之前(上面提到的)过时引用所遇到的相同问题，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，如果有效的话将会更新。

同时，如果有人有更简单/更快的修复方法/建议，请分享。

下面是异常(exception)情况，

2.5版本修复重连后关闭缓存的问题( https://issues.apache.org/jira/browse/IGNITE-2766 )。

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

我确实建议使用 IgniteClientDisconnectedException#reconnectFuture()返回重新连接发生时将完成的 future 的方法。因此，您可以阻止客户端并等待，直到 future 得到解决并且客户端变得活跃。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。
