我第一次尝试 gridgain 并面临一些序列化问题。在尝试使用 GridClosure 在不同节点上投影作业时，我得到了 marshaling exception 。在调试时，似乎失败总是针对 Apache log4j Logger 对象。我很难避免使用记录器，并且想了解这是否是一个已知问题，或者我可以通过某种方式解决这个问题。我的网格配置的 requireSerializable 设置为 false。

您可以将 Log4J 对象设为静态，这样它就不会影响序列化吗？如果没有，GridGain 允许您将记录器资源注入几乎任何东西，包括闭包。您可以在 GridConfiguration 中将 GridLogger 配置为 GridLog4jLogger。

这是一个例子：

GridRunnable run = new GridRunnable() {
    // Can be any logger, including GridLog4jLogger.
    @GridLoggerResource
    GridLogger log;

    @Override public void run() {
        log.info("Hello");

        // Do some logic.
    }
}

或者

// Can be any logger, including GridLog4jLogger
final GridLogger log = grid.log();

GridRunnable run = new GridRunnable() {
    @Override public void run() {
        log.info("Hello");

        // Do some logic.
    }
}

有关更多信息，请参阅 GridGain 文档中的资源注入页面。
