Question

我能够直接使用hibernate来使用hibernate多租户，但我的要求是从jpa使用hibernate。使用来自hibernate的Hibernate SessionFactory：

 SessionFactory factory1=HibernateUtil.getSession();
      Session session1=factory1.withOptions().tenantIdentifier("db2").openSession();
      session1.beginTransaction();

使用JPA

    EntityManagerFactory factory=JpaUtil.getEntityManagerFactory();
    EntityManager em=factory.createEntityManager();
    em.getTransaction().begin();

这样我就可以按照预期的方式跟踪EntityManager创建没有factory1.withOptions().tenantIdentifier("db2").openSession();

的SessionFactory

Exception in thread "main" javax.persistence.PersistenceException: org.hibernate.HibernateException: SessionFactory configured for multi-tenancy, but no tenant identifier specified

如何解决此错误？或者是否有其他方法可以在JPA中使用Hibernate Multi-tenancy？
