嗨，我是 Spring 的新手，过去几天一直在尝试。它最初对我有用，但现在我遇到了错误。有人可以帮忙吗？我正在使用 Spring 3.1。和我得到的休眠 4.1.1 错误：

在您的应用程序的类路径中应该有多个具有该名称net.sf.ehcache.config.CacheConfiguration的类。并且首先找到错误的。要解决此问题，请net.sf.ehcache.config.CacheConfiguration在应用程序的类路径中搜索。您可以使用JFind来完成此任务。然后一一检查，找出哪个是您的期望。您可以使用jd-gui来完成此任务。最后小心地管理你的依赖。

谷歌搜索后，这似乎是一个普遍的问题。希望这封邮件能帮到你。

在您的配置中，不要使用新属性：

<property name="hibernate.cache.region.factory_class" value="net.sf.ehcache.hibernate.EhCacheRegionFactory"/>

但旧的：

<property name="hibernate.cache.provider_class" value="net.sf.ehcache.hibernate.EhCacheProvider"/>

我最近遇到了一个类似的问题，一个类被多次加载。这可能来自于在您的类路径上有同一个类的多个版本。在我的情况下，它net.sf.ehcache.config.CacheConfiguration被加载了两次，一次来自我的 tomcat 的 lib 文件夹，一次来自我的应用程序 lib 文件夹。

要检查类的加载位置和次数，请使用以下命令启动 VM

-verbose:class

这将打印所有正在加载的类以及文件系统上的位置。

然后，您应该通过修复依赖问题或删除任何有问题的 jar 来删除该特定类的任何重复项。也可能会证明您有不同版本的ehcache库，在这种情况下，您需要先解决该问题。如果您发布有关类加载次数以及从何处加载的更多详细信息，我们可能会提供有关如何解决此问题的更详细说明。

我正在加载 ehcahe 和 ehcahe-core，所以我删除了 ehcahce。然后异常消失并排除ehcache-core，如下所示。请确保您的 pom 中不应该有 ehcache 依赖项。请参考此链接了解更多信息：
