Spring -Boot -API Erhalten Sie Fehler 404 auf dem Postboten ⇐ Java

[Guest]

Ich lerne jetzt, wie man Spring Boot verwendet, und es fällt mir schwer herauszufinden, warum meine Postanfragen nicht durchkommen. < /p>
Ich verwende Java 17 , Vs Code und Postman für die Anfragen. Ich habe auch nicht ein Frontend in Betrieb. < /p>
Ich versuche nur, einen Status 200 für die Anfrage zu erhalten. Großartig.
