我使用In Memory HSQLDB开发了一个简单的应用程序，它通过Windows在Websphere Liberty Profile 8.5中运行。现在我已经通过z / OS390 Mainframe（Unix）在Websphere上发布了这样的应用程序，我收到以下错误。
据了解，它不应受操作系统的影响，因为它是相同的jar（hsqldb-2.3.2.jar），相同的JDK版本（7）和完全相同的myapp.ear文件。
所以，我直截了当的问题是：在entityManagerFactory创建过程中出现“NoSuchMethodError：javax / persistence / Table.indexes”的原因是什么？
让我的生活更难的是，在我的本地Websphere中部署的完全相同的耳朵不会弹出这样的错误。一个间接的问题可能是，在Unix中运行的内存HSQLDB中有什么技巧吗？我错误地读了日志，这样的错误实际上是由一些错误的Spring配置引起的？我不这么认为，因为完全相同的耳朵在另一个Websphere中运行如上所述。
我已经苦苦挣扎了4天才找到可能的原因，但我不能。任何建议都将受到高度赞赏。

****于2016年8月28日上午2:45添加巴西，圣保罗时区 由于提供了出色的答案，我最终在Windows Websphere 8.5 Liberty Profile中运行我的应用程序，就像在Mainframe z / OS390 Websphere ND 8.5中一样。我在这里添加了我的未来读者解决方案。基本技巧是（1）降级Hibernate以使用JPA2并使用EntityManager.getDelegate（）
@Component
public class TestDataInitializer {
@Autowired
private EntityManagerFactory entityManagerFactory;
@Autowired
AnotherModelRepository anotherModelRepository;
// I TOOK @PersistenceContext OUT
/* @PersistenceContext
private EntityManager em;*/
public void init() throws Exception {
// I REPLACED entityManagerFactory.unwrap AND sessionFactory.openSession OUT
//SessionFactory sessionFactory = entityManagerFactory.unwrap(SessionFactory.class);
//Session session = sessionFactory.openSession();
// BY createEntityManager AND getDelegate
EntityManager em = entityManagerFactory.createEntityManager();
Session session = (Session) em.getDelegate();
Transaction transaction = session.beginTransaction();
…
@Repository
public class MyModelRepository {
/* @PersistenceContext
private EntityManager em;*/
@Autowired
private EntityManagerFactory entityManagerFactory;
public MyModel findMyModelById(Long MyModel) {
EntityManager em = entityManagerFactory.createEntityManager();
List<MyModel> MyModels = em.createNamedQuery(MyModel.FIND_BY_ID, MyModel.class).setParameter("MyModelId", MyModel).getResultList();
return MyModels.size() == 1 ? MyModels.get(0) : null;
}
public List<MyModel> findOutByIn(Integer certainId){
//SessionFactory sessionFactory = entityManagerFactory.unwrap(SessionFactory.class);
EntityManager em = entityManagerFactory.createEntityManager();
Session session = (Session) em.getDelegate();
String query = "select c from … c "
+ " inner join … o "
+ " where …;
//Session session = sessionFactory.openSession();
Transaction transaction = session.beginTransaction();
List<MyModel> l = session.createQuery(query).list();
return l;
}
答案 0 :(得分：4)
您收到以下错误。
Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax/persistence/Table.indexes()ÝLjavax/persistence/Index;
此错误表示特定类中没有所需的方法。 “index（）”方法可以在JPA 2.1 jar（hibernate-jpa-2.1-api）的“javax.persistence.Table”类中找到。一些如何在你的部署中挑选JPA 2.0 jar（hibernate-jpa-2.0-api），它在Table类中没有这个方法。在您的pom.xml中，您使用的是“hibernate-entitymanager 4.3.7.Final”，它提供了JPA 2.1 jar文件。请在您的服务器中查找JPA 2.0 jars文件，您将收到此错误。
