我在启动HibernateJPAVendorAdapter时遇到了NoClassDefFoundError
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaVendorAdapter' defined in class path resource [META-INF/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org/hibernate/ejb/HibernatePersistence
我检查了几个关于此异常的线程，但未能找到导致此问题的根本原因。我认为JPAVendorAdapter的初始化失败但不确定原因。可能是我的包依赖项之间或我的applicationContext.xml中的不兼容。他们来了; pom.xml（仅包含相关部分）

如果有人能指出我的代码中有什么问题，真的很感激。

请确保您编译的war文件只包含一个org.hibernate.javax.persistence jar，它应该是2.1。 Spring-data-jpa拖拽hibernate-jpa 2.0，你应该在你的pom.xml中专门排除它。
最重要的是，你真的需要删除hibernate-core并且只在你的类路径上有hibernate-entitymanager。确保没有别的东西在hibernate-core上拖延。您正在寻找的类仅包含在hibernate-entitymanager中。
这两件事完全是你的罪魁祸首。编译并检查正确的JAR。如果您从Eclipse中启动Tomcat，请确保您的Deployment Assembly中包含所有正确的类路径文件。做mvn eclipse:eclipse也可能会有帮助。
基本上，在服务器启动之前，请确保所有jar /类都在它们应该的位置。正如我所说的那样，应该已经解决了，但如果不这样做，它肯定有助于识别罪魁祸首。

与NoClassDefFoundError with Spring maven hibernate org/hibernate/ejb/HibernatePersistence相同的问题？ 你错过了依赖：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>${hibernate.version}</version>
</dependency>
如果你有一个NoClassDefFound异常，一个好的起点是查看缺少的类是否在你的一个依赖项中。如果没有，请添加缺少的依赖项。
springframework-orm POM指的是hibernate-entitymanager 4.2.8.Final（参见http://central.maven.org/maven2/org/springframework/spring-orm/4.0.1.RELEASE/spring-orm-4.0.1.RELEASE.pom）你依赖4.1。*。
