获取错误:请求了未知服务[org.hibernate.boot.register.classloading.spi.Cl

Question

我使用的是Spring 3.2.3.RELEASE+Hibernate 4.3.5.Final，我无法启动我的应用程序（在tomcat 6上）

错误：

好的，我解决了这个问题。

首先，Spring3.2与Hibernate 4.3不兼容。您需要将Spring升级到版本4，或者将Hibernate降级到版本4.2（4.2.11.Final对我来说还可以）。

第二，你不能有<tx:注释驱动/>在applicationContext中。你需要将它放在你的调度器上下文中（<servlet_name>-servlet.xml）。我不太确定为什么，但这里有参考：forum.spring.io

根据您的堆栈和代码判断，您使用组件扫描，并且有重复的组件。如何克服这一点在参考指南中进行了解释，并在之前在论坛上多次回答

哇！太棒了！只是移动<tx:注释驱动/>从applicationContext到dispatcherContext，现在就可以工作了！谢谢！
