Spring 3 Security j_spring_security_check

Ich versuche zu erfahren, wie die Frühlingssicherheit funktioniert, also habe ich ein Beispielprojekt heruntergeladen und versucht, diese Lösung in meinem Projekt zu implementieren. Aber wenn ich versuche, mich anzumelden, erhalte ich 404 Fehler und in einer Adressleiste habe ich http://localhost:8080/fit/j_spring_security_check. Ich habe versucht, ähnliche Fragen hier zu betrachten, konnte aber nicht erkennen, wie ich sie in meinem Projekt anwenden kann. Ich wäre wirklich dankbar, wenn mir jemand helfen könnte, der mehr Erfahrung hat.

Meine App-Struktur sieht folgendermaßen aus:
