今天在做jpa与spring整合时,发现个异常... 如下
异常内容: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [beans.xml]:: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: No PersistenceProvider specified in EntityManagerFactory configuration, and chosen PersistenceUnitInfo does not specify a provider class name either
解决方法: 在persisitence.xml文件中添加 <provider>org.hibernate.ejb.HibernatePersistence</provider>
