Java 如何将JPA实体与PersistenceUnits关联
我有两个persistenceUnits映射到两个不同的Oracle模式，这些模式相似，但表名不同。当我尝试部署我的应用程序时，我得到一个Hibernate异常“Missing Table”，它似乎是Hibernate在错误的persistenceUnit中查找表 .ear#POI持久化单元\“：org.hibernate.hibernate异常：缺少表：POI_服务 原因：org.hibernate.HibernateException:缺少表：POI_服务“} 表“POI_服务”属于“POIExtractorPersistenceUnit”持久单元，而不是“POIPersistenceUnit”持久单元 我尝试在persistence.xml文件中列出具有各自persistenceUnits的实体，如下所示，但没有成功，仍然得到相同的错误Java 如何将JPA实体与PersistenceUnits关联,java,oracle,hibernate,jpa,wildfly,Java,Oracle,Hibernate,Jpa,Wildfly,我有两个persistenceUnits映射到两个不同的Oracle模式，这些模式相似，但表名不同。当我尝试部署我的应用程序时，我得到一个Hibernate异常“Missing Table”，它似乎是Hibernate在错误的persistenceUnit中查找表 .ear#POI持久化单元\“：org.hibernate.hibernate异常：缺少表：POI_服务 原因：org.hibernate.HibernateException:缺少表：POI_服务“} 表“POI_服务”属于“POI
