Question

现在我在春季应用程序中收到此错误，这表示什么？怎么解决？

 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Cannot create inner bean 'org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter#2f8b5a' of type [org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter] while setting bean property 'jpaVendorAdapter'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter#2f8b5a' defined in ServletContext resource [/WEB-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

Answer 1

嵌套异常显示NoClassDefFoundError: org/hibernate/ejb/HibernatePersistence，因此很可能找不到包含此类的正确jar。您是否正确设置了类路径？

我认为如果不提供更多详细信息（例如Spring应用程序上下文文件的相关部分），我们就无法提供更具体的帮助。

Answer 2

问题的根源在于您获得了NoClassDefFoundError：

java.lang.NoClassDefFoundError：org / hibernate / ejb / HibernatePersistence

此错误的JavaDoc提供了大量信息：

如果Java虚拟机或ClassLoader实例尝试加载类的定义（作为普通方法调用的一部分或作为使用新表达式创建新实例的一部分），则抛出该类，并且没有类的定义可以被发现。

在编译当前正在执行的类时存在搜索的类定义，但无法再找到该定义。

我会假设类路径问题。
