我想问题在于某些依赖项或插件的版本冲突。编辑：将答案更新为预先修改的问题
org.hibernate.AnnotationException: No identifier specified for entity: com.malykhinvi.mvc1.domain.User
com.malykhini.mvc1.domain.User@IdBasePersistable @Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)
下面是BasePersistable_Roo_JavaBean.aj，它包含getId（）方法；用户是从BasePersistable继承的，所以它也有id的getter；档案在哪里？更新问题。继承（strategy=InheritanceType.TABLE\u PER\u CLASS）不会影响结果。已解决！原因是导入错误：“import org.springframework.data.annotation.Id”而不是“javax.persistence.Id”。
