我有一个相同的问题，我用persistence.xml解决了该问题，在该文件中我声明了db shema时引用了所需的orm.xml文件。
<persistencexmlns="http://java.sun.com/xml/ns/persistence"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"version="2.0" ><persistence-unit name="schemaOne"> . . . <mapping-file>ormOne.xml</mapping-file> . . .</persistence-unit><persistence-unit name="schemaTwo"> . . . <mapping-file>ormTwo.xml</mapping-file> . . . </persistence-unit></persistence>
现在您可以为您的特殊模式创建EntityManagerFactory
EntityManagerFactory emf = Persistence.createEntityManagerFactory("schemaOne");
