Java JUnit+；Spring配置文件：无法加载JDBC驱动程序类

在配置中看不到任何问题

它工作得很好，但在一些重构失败之后

例外情况

您确定spring会接收到

profiles.xml

吗？它是spring启动应用程序吗？如果是这样，请使用

SpringApplicationConfiguration

或

ContextConfiguration

来指定配置文件。您确定

profiles.xml

是由spring拾取的吗？它是spring引导应用程序吗？如果是，请使用

SpringApplicationConfiguration

或

ContextConfiguration

指定配置文件。
