运行JUNIT方法时java.lang.ExceptionInInitializeError

我用一个测试方法运行了一个简单的JUnitTestClass。 我被下面的错误卡住了

stackTrace如下所示

有人能帮我吗？背后的原因是什么

不过，我不必向类路径添加任何jar文件。我通过添加以下系统属性解决了这个问题：

-Dorg.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.SLF4JLogFactory

在通过JUNit运行Web服务时，这是必须的吗？

这是您的整个Stacktrace吗？我希望看到一个“由以下原因引起的”：在此之后阻塞。您可能希望显示一些代码。在@MrWiggles中，我正在尝试调用webservice方法。并检查响应是否为null。我正在尝试使用new实例化webservice，其中抛出此ExceptionInInitializationError。我使用的语句如下XXXXProxy=new XXXXProxy（）；但这是您的全部Stracktrace吗？例外InInitializeRexception通常伴随着一个根本原因stacktrace的其余部分被附加到主stacktrace stacktrace告诉您到底是什么问题。它甚至给您一个链接，让您跟随阅读以解决问题-它以前没有运行，我不知道为什么。现在我设置了正确的如前所述，它是有效的，我不知道为什么！+1尽管如此！
