我制作了我的第一个Spring MVC + Hibernate + MySQL + Maven项目我尝试用Tomcat部署它，但我遇到了这个错误：

我希望你能帮助我。我在stackoverflow和另一个sitde上检查了很多主题，但我没有找到解决方案。谢谢！

解决方案： 我找到了这个并帮助了我：www.mkyong.com/hibernate/hibernate-error-javareflectionmanager-cannot-be-cast-to-metadataproviderinjector/

我删除了： org.hibernate作为冬眠的注解 3.5.6决赛和hibernate核心依赖也，我只保留 org.hibernate作为冬眠-的EntityManager 5.1.0.Final

您还需要添加以下依赖项以获取此修复程序。

<dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>5.1.0.Final</version>
    </dependency>

Hibernate核心将具有hibernate-common-annotation。这是缺少的课程
