我有一个在AWS BeanStalk中运行的应用程序（Tomcat8 + SpringMVC + PostgreSQL + EclipseLink）。
应用程序运行正常，但运行一段时间后（2小时），一个错误开始发生：
截获的错误是：
org.springframework.transaction.CannotCreateTransactionException: Could not open JPA EntityManager for transaction; nested exception is javax.persistence.PersistenceException: Exception [EclipseLink-28013] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.EntityManagerSetupException Exception Description: Unable to deploy PersistenceUnit ###### in invalid state [DeployFailed].

基本错误是：
Attempted to redeploy a session without closing it.
完整的堆栈错误是：

我搜索答案并找到关于此错误的一些结果，并且所有信息都是旧的，2008年及以后就像这样： https://bugs.eclipse.org/bugs/show_bug.cgi?id=256284
我正在使用：
使用扩展的JpaTransactionManager类来租赁：
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;
}
我正在努力解决这个问题，但没有找到任何方法。
这里有人对这种情况有所了解吗？
经过多次测试后，我可以使用apache AB模拟问题来生成并发和一些请求。
没有显示其他登录信息。
运行相同的负载测试而不使用类MultiTenantJpaTransactionManager扩展JpaTransactionManager没有问题。
我认为问题出在持久性单位名称或其他方面。即使停止请求，在导致问题之后，错误仍然存在，直到重新启动服务器。
答案 0 :(得分：0)
用于MultiTenantJpaTransactionManager的解决方案是由我开发的，但并不完全正确。你已经知道了......我已经把它改了一点。我希望这个应该有效：
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());
}
}
如果您有时间，请阅读my article有关此解决方案的原因。也许你不需要这个＆＃34; hacking＆＃34;一点都不。
