Spring MVC mit Kacheln: java.lang.NoClassDefFoundError: org/Springframework/Bohnen/Fabrik/NoUniqueBeanDefinitionException

Question

Ich bin neu im Frühling und ich folge einige der Online-Tutorial-Website, meine erste Website mit Spring-Mvc, Winterschlaf zu versuchen mit mySQL als Backend, Kacheln.

Ich habe einige der Dateien konfiguriert und alle erforderlichen JAR-Dateien in dieses Projekt aufgenommen. Wenn ich versuche, meine Apache-tomcat-7-Instanz aus meiner Eclipse zu starten, erhalte ich den folgenden Fehler.

Ich habe mehr als 15 Threads mit der gleichen Ausnahme gelesen, aber seit meinem Mangel an Know-how konnte ich mein Problem nicht lösen. Ich kämpfe seit 2 Tagen um dieses Problem zu lösen.

Lassen Sie mich wissen, wenn ich andere Informationen einfügen muss.

Unten ist mein Fehler Nachricht:

Answer 1

Sie haben den Spring classes (abhängig Gläser) während des Projekt Kompilierung zur Verfügung gestellt, aber nicht während der Laufzeit.

Ihr Apache-tomcat-7-Server kann die Spring-Abhängigkeiten (JAR-Dateien) NICHT auflösen und laden, daher müssen Sie die Spring-JARs dem Tomcat-Klassenpfad hinzufügen.

Kopieren Sie also die Jug-Dateien mit Federabhängigkeit in den Ordner Tomcat/webapps/yourproject/WEB-INF/lib folder oder direkt in den Ordner Tomcat/lib.
