彈簧加載上下文配置文件時發生Java異常 - 發生在UNIX而非Windows中

我一直堅持使用這一段現在。我已經創建了這個項目的一個小子集，並且重現了這個問題。基本上我正在運行一個測試，它將一個bean的spring上下文文件加載到ClassPathXmlApplicationContext對象中。彈簧加載上下文配置文件時發生Java異常 - 發生在UNIX而非Windows中

奇怪的是，在Windows上，當我從IDE（Eclipse/Intellij）運行時，以及在運行maven命令行時，測試通過的很好。當從UNIX機器（紅帽企業Linux 5）運行測試時（這是代碼不可避免的結果），它會失敗。

在下面的異常中抱怨LookUtils類。我看不出它爲什麼要創建這個類，但我注意到的一件事是它有一個私有構造函數。另外，我使用spring v2.5.6，出於安全原因必須堅持這一點。我很堅持這一個，所以任何幫助將不勝感激。

謝謝。

這裏是個例外：

這裏是我的測試：

package StartupTest; 

import org.junit.Test; 
import org.springframework.context.support.ClassPathXmlApplicationContext; 

public class AppTest { 
    @Test 
    public void testGuiStartup() { 
     new ClassPathXmlApplicationContext("startup-context.xml"); 
    } 
}

它看起來像jgoodies的外觀庫不在類路徑中。 – 2013-05-09 12:38:29

但是，如果將它添加爲Maven依賴關係，它會自動添加到類路徑中？如何確認/解決這個問題？ – user528827 2013-05-09 12:47:02

對不起。我誤解了這個問題，並認爲你在運行時得到了這個，而不是執行單元測試。 – 2013-05-09 12:52:07

終於明白了這一點。畢竟很簡單。所以它在UNIX（紅帽企業Linux 5）上失敗的原因是因爲這臺機器上沒有圖形界面！沒有侏儒，沒有KDE或任何東西。所以它在嘗試配置應用程序GUI的外觀時感到失敗。事後看來，我應該提到我使用TeamCity來運行這些測試，而且我從來沒有身在RHEL5服務器的前面。

解決方案是創建一個只運行GUI測試的新TeamCity構建，它在Windows機器上執行此操作。

因此，如果在遠程計算機上運行GUI測試，請確保它具有圖形支持！

是在RHEL服務器上設置爲true的java.awt.headless？假設它不是，你可能會得到更有意義的錯誤信息。它應該在沒有gui的服務器中設置爲true。如果是這樣，這是一個jgoodies不檢查的問題，但我認爲他們會檢查它。 – eis 2013-06-14 11:57:49
