Fehler beim Erstellen von Bean mit dem Namen 'entityManagerFactory' in der Klassenpfadressource [spring/business-config.xml]

Ich habe ein Problem mit einer Verbindung zwischen der dataSource und der entityManagerFactory. Die Daten werden nicht gesendet oder etwas oder die Bean wird nicht erstellt. Bis jetzt habe ich nicht die h2 Datenbank-Engine benutzt (erstelle eine In-Memory-Datenbank), so dass ich jetzt keine Ahnung habe, wo ich hinschauen oder ändern sollte. Jeder Rat ist willkommen.Fehler beim Erstellen von Bean mit dem Namen 'entityManagerFactory' in der Klassenpfadressource [spring/business-config.xml]

Auch ich suchte bisher auf der Seite nach Lösungen, aber keiner half mir bei diesem Problem.

Die App ist ein Tutorial von YouTube (ich werde Links für den Quellcode und Video) und ich versuche, es auf meinem PC zu integrieren, aber ich habe Schwierigkeiten.

Der Link zu dem Video tutorial (der 7. Teil ist die letzte, die ich über Pflege): https://www.youtube.com/playlist?list=PL4gCdGOq-cxJrbRMWjrIvGhYqQO1tvYyX

Der Link zum Quellcode: https://github.com/chrishenkel/spring-angularjs-tutorial-7

Dies ist die Konsole Ausgabefehler:

Es scheint, Sie vermissen die unter Abhängigkeit

<dependency> 
    <groupId>org.apache.commons</groupId> 
    <artifactId>commons-pool2</artifactId> 
    <version>2.0</version> 
</dependency>

Versuchen Sie es erneut, nachdem es hinzugefügt wird.

Nein, anscheinend hat es einige Sachen gelöst, aber nicht alles. Fehler beim Erstellen von Bean mit dem Namen 'entityManagerFactory' in der Klassenpfadressource [spring/business-config.xml]: Aufruf der init-Methode fehlgeschlagen; geschachtelte Ausnahme ist java.lang.NoSuchMethodError: org.apache.commons.pool2.impl.GenericObjectPool.setTestOnCreate (Z) V –

Sie können überprüfen, ob diese Methode in der Jar hinzugefügt wird. Wenn nicht, füge commons pool2 jar mit der verfügbaren Methode hinzu. –

das Problem war über die Feder Versionen Management, die Feder-Version waren nicht kompatibel mit den anderen Abhängigkeiten. –
