我是 Junit 框架的新手。我正在尝试使用反射 API 从 Junit 测试 class 调用另一个 class 中的私有方法。 运行 JUnit 测试时出现以下错误：

看来这与你的私有方法无关。在线 SP 的构造函数中抛出异常：
plnCategoryList = persister.getSortedList( persClass, new PersistableDescriptionComparator());
当我尝试调用 searchpln() 方法时，它未能初始化数据库连接，因此我得到 java.lang.ExceptionInInitializerError。
问题现已解决。我已通过在 class.
