NoClassDefFoundError: org/hibernate/ejb/HibernatePersistence
NoClassDefFoundError: org/hibernate/ejb/HibernatePersistence
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，但未能找出其根本原因。我认为 JPAVendorAdapter 的初始化失败但不确定原因。也许我的包依赖项之间不兼容，或者在我的 applicationContext.xml 中不兼容。他们来了;

与 NoClassDefFoundError with Spring maven hibernate org/hibernate/ejb/HibernatePersistence 相同的问题？
你错过了一个依赖：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>${hibernate.version}</version>
</dependency>
如果您遇到 NoClassDefFound 异常，一个好的起点是查看缺少的 class 是否在您的依赖项 jar 之一中。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）您依赖 4.1.*。
请确保您编译的 war 文件只包含一个 org.hibernate.javax.persistencejar，它应该是 2.1。 Spring-data-jpa 拖拽 hibernate-jpa 2.0，你应该在你的 pom.xml.
中明确排除它
最重要的是，您确实需要删除 hibernate-core，并且在您的 class 路径上只包含 hibernate-entitymanager。确保没有其他东西拖累 hibernate-core。您要查找的 class 仅包含在 hibernate-entitymanager 中。
这两件事绝对是你的罪魁祸首。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 class 路径文件。这样做 mvn eclipse:eclipse 也可能有所帮助。
基本上，在服务器启动之前，确保所有 jars/classes 都在它们应该在的位置。按照我说的去做应该已经解决了它，但如果没有，它肯定有助于找出罪魁祸首。
