Jeder ist da ... – user1126046

Wo ist der Fehler statck Spur? "nicht die DB-Verbindung zu bekommen" wird einfach nicht hilfreich sein. –

hinzugefügt das Fehlerprotokoll pls ein Blick auf es – user1126046

eine Möglichkeit besteht, dass Sie möglicherweise nicht die Hibernate-Session nach dem mit ihm getan veröffentlichen .. versuchen, die OpenSessionInViewFilter verwenden, vermeiden mit factory.openSession()

ich ähnliche Probleme in einem der Projekte arbeite ich konfrontiert hatte auf .. Es wäre sehr hilfreich, wenn Sie den Stacktrace posten können, bevor ich mir der Ursache sicher sein kann.

aktualisiert das Fehlerprotokoll, pls haben es sich angesehen – user1126046

können Sie überprüfen, ob Ihre Ausnahme http://issues.liferay.com/browse/LPS-2769 oder https://forum.hibernate.org/viewtopic.php?f=1&t=943079&p=2440195#p2440195 da es zwei Gründe für die Ausnahme gibt. –

scheint, dass nur..aber Maxwait ist auf -1 in meinem hibernate.config.xml gesetzt – user1126046

<property name="testOnBorrow" value="true"/>

ODER

  <prop key="hibernate.dbcp.validationQuery">select 1</prop> 
      <prop key="hibernate.dbcp.testOnReturn">true</prop>

hinzufügen Eigenschaft in Datenbank-Verbindung Bean in xml

oben Die prüft Verbindungen jedes Mal, wenn Sie aus dem Pool ausleihen.
