Konnte Sicht mit Namensfehler nicht auflösen Frühling MVC 4 + Apache-Fliesen 3

Question

Ich erhalte einen Fehler, wenn ich Apache Fliesen 3 mit Frühling MVC 4 integrieren möchte. Bitte helfen Sie mir mit dieser Situation. Idee ist es, Seiten zu erstellen, die mit Apache Tiles dynamisch aktualisiert werden. Ich habe die Abhängigkeiten überprüft und sie scheinen alle in Ordnung zu sein. Ich denke, dass meine Konfiguration etwas fehlt oder der Controller die Kachel-Konfigurationsdatei nicht erkennt.

Bitte helfen Sie mir dabei. Ich bin ziemlich neu in der Entwicklung von Spring MVC und Apache Tiles Anwendungen. Bitte schlage vor, was mit diesem Code schief gegangen sein könnte.

Answer 1

Sie haben als angegeben, aber die Basis-definiation nicht definiert ist (es App-default) .Es sollte entweder app-default oder App erweitern -default sollte als app-base geändert werden
