我有一个新的SpringBoot应用程序来公开一些与生活在jar中的实体相关的服务(作为POM中的依赖项包含在内).对于数据访问,我计划使用SpringData,因此我可以使用优秀的JpaRepository而不是手动编写DAO.
从代码中可以看到jar,所以一切都编译得很好,但是当Spring开始连接bean时,它会抛出异常:
Caused by: java.lang.IllegalArgumentException: Not a managed type: class com.companyName.common.countrytype.Country
at org.hibernate.jpa.internal.metamodel.MetamodelImpl.managedType(MetamodelImpl.java:210) ~[hibernate-entitymanager-5.0.11.Final.jar:5.0.11.Final]
at org.springframework.data.jpa.repository.support.JpaMetamodelEntityInformation.<init>(JpaMetamodelEntityInformation.java:70) ~[spring-data-jpa-1.10.3.RELEASE.jar:na]
我已经尝试添加@EnableJpaRepositories指向扩展JpaRepository的接口包,但仍然没有成功.
但是,如果我使用粘贴在我的新项目中的@Entity副本,一切都会很好.(而不是使用jar中的实体)
你是否看到我缺少的东西使用一个在jar中声明的@Entity的SpringData/JpaEntity？你有没有做过类似的事情？
这是我的代码:
