org.springframework.beans.factory.BeanCurrentlyInCreationException: Fehler beim Erstellen Bean mit dem Namen 'SessionFactory'

Question

Ich verwende Spring und Hibernate für die Konfiguration mit mysql db.

Meine we.xml Datei hat folgenden Code:

<?xml version="1.0" encoding="UTF-8"?> 
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <welcome-file-list> 
     <welcome-file>index.jsp</welcome-file> 
    </welcome-file-list> 
</web-app> 

Meine applicationContext.xml Datei hat folgende Importe:

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"

Ich habe entsprechende lib enthalten. Nun zu der Zeit das Projekt laufen, ich bin immer folgende Fehlermeldung:

Kann jemand irgendwelche Lösungen haben, warum meine session Bean geben Fehler?

Vielen Dank im Voraus ...

Answer 1

Frühling Ihnen genau sagen, was das Problem ist, man muss nur das Protokoll und verschachtelte Fehlermeldung lesen:

Kann nicht Bezug auf Bohne lösen ‚session‘ beim Setzen der Bean-Eigenschaft 'sessionFactory'; verschachtelte Ausnahme ist org.springframework.beans.factory.BeanCurrentlyInCreationException: Fehler beim Erstellen der Bohne mit dem Namen ‚session‘: FactoryBean, die derzeit in der Schöpfung zurückgegeben null von getObject

Ein bisschen Google Suche läßt vermuten, dass dieser Fehler Nachricht ist in der Regel das Ergebnis von a circular dependency, und führte auch zu a mailing list post that recommends Entfernen default-autowire="detect" von Ihrem <beans> Element.
