当我在我的 spring 简单数据库连接代码中定义 applicationContext 时，我收到了这个错误。
但是当我将 applicationContext 放置在 java (DatabaseTestConnection.java) 所在的位置时，它可以毫无问题地连接。
线程“主”org.springframework.beans.factory.BeanDefinitionStoreException 中的异常：IOException 从类路径资源 [applicationContext.xml] 解析 XML 文档；嵌套异常是 java.io.FileNotFoundException: 类路径资源 [applicationContext.xml] 无法打开，因为它不存在
