我正在尝试创建一个具有多个持久性单元的项目。但是当我添加一个持久性单元时，我现有的测试用例（没有 Hibernate-OGM）失败了，因为该测试用例也在查看其他 Hibernate-OGM 持久性单元。
单元测试用例：
public class AuthorTest {
Logger log = Logger.getLogger(this.getClass().getName());
EntityManagerFactory emf ;
@Before
public void init() {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("templatePU");}
@After
public void destroy() { emf.close();}
@Test
public void persist() {
log.info("...persist...");
EntityManager em = emf.createEntityManager();
em.getTransaction().begin();
Author author = new Author();
author.setFirstName("Ayman");
author.setLastName("Patel");
em.getTransaction().commit();
em.close();
}
}
persistance.xml：

我尝试在 @PersistanceUnit (reference link) 上添加 EntityManagerFactory，但它给出了相同的错误。有没有其他方法可以为测试类选择单个持久性单元？
