Spring XD -测试失败

Question

我从github获取了XD源代码的最新副本，并尝试构建本地。当我运行构建任务时，出现以下错误。我在端口6379上运行Redis。不确定是不是还丢了什么东西。

我的/etc/hosts在Mac上看起来不错。我不得不做一个-x测试来跳过测试。有什么可能的解决方案吗？我应该运行gemfire吗？

Answer 1

很奇怪的一个。我同意，您的/etc/hosts看起来不错。我在Linux机器上看到过这种情况，它们有时使用127.0.1.1而不是127.0.0.1。如果您是GemFire用户，您可能希望检查主目录、当前目录或类路径中是否有gemfire.properties或cache.xml文件。GemFire因为能找到这些东西而臭名昭著。

Answer 2

同意，您的/etc/hosts文件看起来很好(不过，我会格式化它，使每个主机条目都在一行上)。

看起来你可能在运行GemFire 7？

另外，您在Mac上运行的Java供应商/版本是什么(Apple或Oracle JDK/JRE及其版本)？

您的Mac版本可能是一个因素(？)，特别是如果您禁用了网络(即没有“活动的”NIC，使用有效的IP连接，由ifconfig确定)，尽管这一点不太清楚。

简而言之，当环回地址只指定了IP (在/etc/ SocketCreator文件中)，或者像InetAddress.getLocalHost()返回的地址时，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)。

这个解析过程相当复杂，不幸的是，在装入SocketCreator类时，它包含在“静态初始化器”块中。

InetAddress.getLocalHost()似乎不太可能返回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值设定项块中初始化。

所以，要么没有调用静态初始化器，要么就是InetAddress.getLocalHost() (可能是因为网络被禁用了？)返回null，尽管查看GemFire的代码可能会导致NullPointerException (我不确定是否在某个地方被吞噬)，所以它看起来更像是前者，但两个答案似乎都不太可能，真的。

一种可能的解决方法(因为它避免了GemFire成员启动时的IP解析步骤，在堆栈跟踪中可以看到)是将第31行的Spring XD测试类JsonStringToObjectTransformerTests修改为...

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warn可以减少GemFire噪声，并显著加快测试速度。

希望这能有所帮助。
