Spring XD - 測試失敗

Question

我從github上獲取了XD源代碼的最新副本，並試圖在本地構建。當我運行構建任務時，出現下面的錯誤。我在端口6379上運行Redis。不知道是否還有其他東西丟失。

我的/ etc/hosts在Mac中似乎很好看。我不得不做一個-x測試來跳過測試。任何可能的決議？我應該運行gemfire嗎？

Answer 1

甲怪異之一。我同意，你的/ etc/hosts看起來不錯。我在Linux上看到過這種情況，有時使用127.0.1.1而不是127.0.0.1。該測試簡單地啓動一個緩存 new CacheFactory().create();如果您是GemFire用戶，則可能需要檢查您的主目錄，當前目錄或類路徑中是否存在任何gemfire.properties或cache.xml文件。 GemFire因發現這些而臭名昭着。

Answer 2

同意，你的/ etc/hosts文件看起來沒問題（但是，我會格式化它，以便每個主機條目都在一行上）。

似乎你可能運行GemFire 7？

此外，您在Mac（Apple或Oracle JDK/JRE和版本）上運行的是哪個Java供應商/版本？

您的Mac OS X版本可能是一個因素（???），尤其是如果您禁用了網絡連接（即沒有「有效」網卡，由有效IP連接，由ifconfig確定）比清楚。

簡而言之，當環回地址僅指定了IP時（如在/ etc/hosts文件中），GemFire會嘗試解析/查找本地系統的實際IP地址（使用GemFire的內部SocketCreator類）由InetAddress.getLocalHost（）返回。

這個解析過程相當複雜，不幸包含在SocketCreator類中的「靜態初始化程序」塊中，當該類被加載時。

這似乎不大可能，InetAddress.getLocalHost（）將永遠返回null，但在這種情況下，爲什麼在的GemFire被UnknownHostException異常拋出的原因是因爲SocketCreator.localHost類的成員變量是空...

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

「靜態初始化程序塊」內初始化「SocketCreator.localHost」靜態成員變量。

因此，無論是靜態初始化沒有被調用或InetAddress.getLocalHost（）（可能是因爲網絡被禁用？）返回null，雖然看通過GemFire的代碼，將導致NullPointerException（我不確定是否可能有在某處被吞噬），所以它似乎更像前者的路線，但實際上，答案似乎都不太可能。

一個可能的解決方法（因爲它避免了啓動GemFire成員資格的IP解析步驟，就像在堆棧跟蹤中看到的那樣）將修改第31行的Spring XD測試類JsonStringToObjectTransformerTests爲...

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

這避免從DirectChannel.initAddress（DirectChannel.java:898）的SocketCreator.getLocalHost（）調用。

此外，將日誌級別設置爲警告可降低GemFire噪音並顯着加快測試速度。

希望這會有所幫助。
