meine eine Anwendung mit Feder als dynamische Web-Projekt realisiert diese Anwendung nicht eine Feder Boot ist, und ich habe Feder 3.2.2 Glas in meinem Classpath kann jede Stelle mir bitte sagen, wo ich das Problem verursacht bin .

Answer 1

Die beiden Taglibs von Spring werden von Spring MVC unterstützt. Sie müssen spring-webmvc-3.2.2.RELEASE.jar herunterladen (um mit Ihrer aktuellen Version konsistent zu bleiben) und die Bibliothek in den Ordner WEB-INF/lib Ihrer Anwendung kopieren.

EDIT: Hier ist der Maven-Abhängigkeitsbaum eines funktionierenden Prototyps (mit Taglibs und Spring 3.2.2).

+- org.springframework:spring-webmvc:jar:3.2.2.RELEASE:compile 
| +- org.springframework:spring-beans:jar:3.2.2.RELEASE:compile 
| +- org.springframework:spring-context:jar:3.2.2.RELEASE:compile

Der Code läuft auf Jetty 9.2.17. Sie könnten überprüfen, ob Ihre Tomcat-Instanz JSTL in ihrem lib-Ordner hat.
