Spring XD - 测试失败

Question

我从github上获取了XD源的最新副本并尝试构建本地。当我运行构建任务时，会出现以下错误。我在端口6379上运行Redis。不确定是否还有其他东西丢失。

我的/ etc / hosts似乎在Mac上看起来很好。我不得不做一个-x测试来跳过测试。任何可能的决议？我应该运行gemfire吗？

Answer 1

奇怪的一个。我同意，你的/ etc / hosts看起来不错。我在Linux机器上看到过这种情况，有时使用127.0.1.1而不是127.0.0.1。测试只是启动缓存 new CacheFactory().create();如果您是GemFire用户，您可能需要检查主目录，当前目录或类路径中是否有任何gemfire.properties或cache.xml文件。 GemFire因发现这些而臭名昭着。

Answer 2

同意，您的/ etc / hosts文件似乎没问题（但是，我会将其格式化，以便每个主机条目都在一行上）。

好像你可能正在运行GemFire 7？

此外，您在Mac上运行的Java供应商/版本（Apple或Oracle JDK / JRE和版本）？

您的Mac OS X版本可能是一个因素（???），特别是如果您已禁用网络（即没有“活动”NIC，连接有效IP，由ifconfig确定），尽管如此不太清楚。

简而言之，当环回地址仅指定IP时（如在/ etc / hosts文件中）或返回时，GemFire会尝试解析/查找本地系统的实际IP地址（使用GemFire的内部SocketCreator类）通过InetAddress.getLocalHost（）。

这个解决过程非常复杂，不幸的是，在加载类时，它包含在SocketCreator类中的“静态初始化程序”块中。

InetAddress.getLocalHost（）似乎不可能返回null，但在这种情况下，抛出GemFire中的UnknownHostException的原因是因为SocketCreator.localHost类成员变量为null ...

310:  public static InetAddress getLocalHost() throws UnknownHostException {
311:    if (localHost == null) {
312:      throw new UnknownHostException();
313:    }
314:    return localHost;
315:  }

“SocketCreator.localHost”静态成员变量在静态初始化程序块中初始化。

那么，是不是调用了静态初始化程序，还是没有调用InetAddress.getLocalHost（）（可能是因为网络已被禁用？）返回null，虽然通过GemFire的代码查看会导致NullPointerException（我不确定是否可能已经获得）吞噬了某个地方），所以看起来更像是前者，但这两种答案似乎都不可能，真的。

一种可能的解决方法（因为它避免了启动GemFire成员资格时的IP解析步骤，如堆栈跟踪中所示）将修改第31行的Spring XD测试类JsonStringToObjectTransformerTests为... < / p>

31:    new CacheFactory().set("mcast-port", "0").set("log-level", "warning").create();

这避免了来自DirectChannel.initAddress（DirectChannel.java:898）的SocketCreator.getLocalHost（）调用。

此外，将日志级别设置为警告会降低GemFire噪音并显着加快测试速度。

希望这有帮助。
