本文介绍了在类路径资源[jpaContext.xml]中定义名称为'entityManagerFactory'的Bean时创建错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在春天遇到一个问题，我是一个新手，在Hibernate，JPA和Maven中使用这个框架，我正在关注一个关于pluralsight的教程，但是当在服务器中启动应用程序时，我有这个错误信息。

java.lang.IllegalStateException：无法加载JDBC驱动程序类[com .postgresql.driver]
没有类 com.postgresql.driver 有一个 org.postgresql.Driver 类。相应地更改您的配置。
I am having a problem with spring , I am a newbie using this framework with Hibernate , JPA and Maven , I am following a tutorial on pluralsight but when launching the app in the server I have this error message.
