尝试连接MySQL DB时创建EntityManagerFactory时出错

时间：2016-06-27 13:58:51

标签： mysql spring hibernate maven spring-mvc

我试图使用Spring制作ASP.NET MVCMusicStore。

我使用maven作为依赖项，使用jetty作为服务器和MySQL数据库。

我在运行时遇到此错误：

  

org.springframework.beans.factory.BeanCreationException：错误   创建名为“emf＆＃39;”的bean在ServletContext资源中定义   [/WEB-INF/spring-servlet.xml]：调用init方法失败;   嵌套异常是javax.persistence.PersistenceException：   [PersistenceUnit：MVCMusicStorePU]无法构建   EntityManagerFactory的

请帮助我。我会很感激。
