Weblogic12c org.hibernate.service.UnknownServiceException：请求了未知服务[org.hibernate.engine.jdbc.connections.spi.ConnectionProvider]

Question

env：weblogic12c oracle11g spring4 hibernate4

当我在weblogic服务器控制台上重新启动Web应用程序时，先停止然后再启动，Web应用程序将引发Exception。但是，每次我重新启动weblogic12c（不是Web应用程序）时，都可以毫无问题地访问Web应用程序。

有人可以帮我理解为什么吗？
