Eclipselink-error：试图在不关闭会话的情况下重新部署会话

Question

我有一个在AWS BeanStalk中运行的应用程序(Tomcat8+SpringMVC+PostgreSQL+EclipseLink)。

我正在使用：

• eclipselink-org.eclipse.persistence.jpa-2.5.2
• Spring MVC-许多特性-4.1.4.发布
• postgreSQL-org.postgreSQL-9.3-1100-jdbc41

并将扩展的JpaTransactionManager类用于租赁，即：

public class MultiTenantJpaTransactionManager extends JpaTransactionManager               {
protected static final Logger log = Logger.getLogger(MultiTenantJpaTransactionManager.class);

@Autowired
CurrentTenantResolverService currentTenantResolverService;

/**
 * NOTE:
 * Maybe it would be also possible to replace existing entityManager in transaction with new but it
 * isn't a good idea because of rollback and other problems.
 * So when new tenant is required always start new transaction for it.
 * 
 */


@Override
protected EntityManager createEntityManagerForTransaction() {
    EntityManager em = super.createEntityManagerForTransaction();

    boolean refreshed = false;
    ServerSession ss = ((EntityManagerImpl) em.getDelegate()).getServerSession();
    Map sessionProp = ss.getProperties();
    // don't run it if tenant didn't change
    // it should be quite faster then
    String OrgId = currentTenantResolverService.getCurrentTenantId();
    // set new tenant as property for actual session
    // while refreshing metadata it will be used from actual session for new session
    sessionProp.put(PersistenceUnitProperties.MULTITENANT_PROPERTY_DEFAULT, OrgId);
    MetadataRefreshListener mrl = ((EntityManagerImpl) em.getDelegate()).getServerSession().getRefreshMetadataListener();
    // metadata refresh listener is empty if it was already run for actual transaction (same entity manager)
    // because it is placed in createEntityManagerForTransaction now this shouldn't happen but to be sure...
    if (mrl != null) {
        Map<String, Object> prop = new HashMap<String, Object>();
        // metadata will be refreshed for next created entity manager
        mrl.triggerMetadataRefresh(prop);
        refreshed = true;
    }

    // if metadata for "old" entity manager wasn't refreshed we don't need to create a new one
    return refreshed ? super.createEntityManagerForTransaction() : em;
}

Answer 1

MultiTenantJpaTransactionManager使用的解决方案是我开发的，但并不完全正确。你已经知道了...我稍微修改了一下。我希望这个应该管用：

public class MultiTenantJpaTransactionManager extends JpaTransactionManager {

/**
 * This process shouldn't be interrupted by concurrent thread. Therefore the method is synchronized.
 */
@Override
protected synchronized EntityManager createEntityManagerForTransaction() {
    EntityManager em = null;
    Map<String, Object> properties = getJpaPropertyMap();
    // get EMF from JpaTransactionManager
    EntityManagerFactory emf = ((EntityManagerFactoryInfo) getEntityManagerFactory()).getNativeEntityManagerFactory();
    boolean isMetadataExpired = ((EntityManagerFactoryImpl) emf).unwrap().getSetupImpl().isMetadataExpired();
    // it is needed to get EM to update metadata if they are marked as expired otherwise serverSesstion and
    // therefore also actualTenant value being get below wouldn't be actual
    if (isMetadataExpired) {
        em = (!CollectionUtils.isEmpty(properties) ?
                emf.createEntityManager(properties) : emf.createEntityManager());
    }
    Server ss = JpaHelper.getServerSession(emf);
    String actualTenant = (String) ss.getProperty(PersistenceUnitProperties.MULTITENANT_PROPERTY_DEFAULT);
    // don't run it if tenant didn't change
    // it should be quite faster then
    if ((actualTenant == null && SecurityHelper.getActiveTenantSchema() != null) ||
            (actualTenant != null  && !actualTenant.equals(SecurityHelper.getActiveTenantSchema()))) {
        Map newProperties = new HashMap();
        newProperties.put(PersistenceUnitProperties.MULTITENANT_PROPERTY_DEFAULT, SecurityHelper.getActiveTenantSchema());
        JpaHelper.getEntityManagerFactory(emf).refreshMetadata(newProperties);
    } else
    if (em != null) {
        // don't get it again
        // it is unnecessary
        return em;
    }

    return (!CollectionUtils.isEmpty(properties) ? emf.createEntityManager(properties) : emf.createEntityManager());
}
}

如果你有时间，你应该读一下我的文章，关于是什么导致了这个解决方案。也许你根本不需要这种“黑客攻击”。
