希望你能帮助我。我在 stackoverflow 和另一个 sitede 上检查了很多主题，但没有找到解决方案。 谢谢!
解决方案: 我发现了这个，它对我有帮助:www.mkyong.com/hibernate/hibernate-error-javareflectionmanager-cannot-be-cast-to-metadataproviderinjector/
我删除了: 组织 hibernate hibernate注释 3.5.6-最终 和 hibernate 核心依赖关系也只有我保留 组织 hibernate Hibernate实体管理器 5.1.0.最终版
最佳答案
您还需要添加以下依赖项才能获得此修复。
<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。这是缺少类(class)

关于java - org.springframework.beans.factory.BeanCreationException : NoClassDefFoundError: Could not initialize class org. hibernate.ann，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/37335059/
