Spring XD - 测试失败

Question

我从github上获取了XD源代码的最新副本，并试图在本地构建。当我运行构建任务时，出现下面的错误。我在端口6379上运行Redis。不知道是否还有其他东西丢失。

我的/ etc/hosts在Mac中似乎很好看。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

甲怪异之一。我同意，你的/ etc/hosts看起来不错。我在Linux上看到过这种情况，有时使用127.0.1.1而不是127.0.0.1。该测试简单地启动一个缓存 new CacheFactory().create();如果您是GemFire用户，则可能需要检查您的主目录，当前目录或类路径中是否存在任何gemfire.properties或cache.xml文件。 GemFire因发现这些而臭名昭着。

Answer 2

同意，你的/ etc/hosts文件看起来没问题（但是，我会格式化它，以便每个主机条目都在一行上）。

似乎你可能运行GemFire 7？

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

您的Mac OS X版本可能是一个因素（???），尤其是如果您禁用了网络连接（即没有“有效”网卡，由有效IP连接，由ifconfig确定）比清楚。

简而言之，当环回地址仅指定了IP时（如在/ etc/hosts文件中），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）由InetAddress.getLocalHost（）返回。

这个解析过程相当复杂，不幸包含在SocketCreator类中的“静态初始化程序”块中，当该类被加载时。

这似乎不大可能，InetAddress.getLocalHost（）将永远返回null，但在这种情况下，为什么在的GemFire被UnknownHostException异常抛出的原因是因为SocketCreator.localHost类的成员变量是空...

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

“静态初始化程序块”内初始化“SocketCreator.localHost”静态成员变量。

因此，无论是静态初始化没有被调用或InetAddress.getLocalHost（）（可能是因为网络被禁用？）返回null，虽然看通过GemFire的代码，将导致NullPointerException（我不确定是否可能有在某处被吞噬），所以它似乎更像前者的路线，但实际上，答案似乎都不太可能。

一个可能的解决方法（因为它避免了启动GemFire成员资格的IP解析步骤，就像在堆栈跟踪中看到的那样）将修改第31行的Spring XD测试类JsonStringToObjectTransformerTests为...

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

这避免从DirectChannel.initAddress（DirectChannel.java:898）的SocketCreator.getLocalHost（）调用。

此外，将日志级别设置为警告可降低GemFire噪音并显着加快测试速度。

希望这会有所帮助。
