创建bean持久性时出错，NoSuchMethodError: javax/ entityManagerFactory /Table.index
创建bean持久性时出错，NoSuchMethodError: javax/ entityManagerFactory /Table.index
提问于 2016-08-27 09:25:59
我使用内存中的HSQLDB开发了一个简单的应用程序，它在Windows上的Websphere Liberty Profile 8.5中运行。现在我已经在z/OS390大型机(Unix)上的Websphere中发布了这样的应用程序，并且我得到了下面的错误。
据了解，它不应该受到操作系统的影响，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。
因此，我的直接问题是:在entityManagerFactory创建过程中使用"NoSuchMethodError: javax/持久性/表.索引“的原因是什么？
让我的生活更艰难的是，在我本地的Websphere中部署的完全相同的ear不会弹出这样的错误。一个间接的问题可能是，在Unix中运行内存中的HSQLDB有什么技巧吗？我是不是读错了日志，而这样的错误实际上是由某个错误的Spring配置引起的？我不这么认为，因为正如所说的那样，完全相同的ear在另一个Websphere中运行。
我已经努力了4天，想找出一个可能的原因，但是我找不到。任何建议我都会非常感谢。

</project>*添加于2016年8月28日凌晨2:45巴西，圣保罗时区感谢提供的出色答案，我终于让我的应用程序像在大型机z/OS390 Websphere ND 8.5中一样在两个Windows Websphere 8.5 Liberty配置文件中运行。我在这里为未来的读者添加了我的解决方案。基本技巧是(1)降级Hibernate以使用JPA2和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;

你得到了下面的错误。
Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax/persistence/Table.indexes()ÝLjavax/persistence/Index;此错误指示所需的方法在特定类中不可用。可以在JPA2.1JAR (hibernate- JPA - 2.1 -api)的"javax.persistence.Table“类中找到"indexes()”方法。在你的部署中，它是如何选择JPA2.0JAR (hibernate- JPA - 2.0 -api)的，它在Table类中没有这个方法。在您的pom.xml中，您正在使用"hibernate-entitymanager 4.3.7.Final"，它提供了JPA2.1JAR文件。请在收到此错误的服务器中查找JPA2.0JARS文件。
