Ich stehe vor einem Problem, wenn ich mein Spring-Projekt erstellen möchte. Der Fehler, den ich von Eclipse bekommen ist:java.lang.ClassNotFoundException: org.slf4j.Logger

Sie sollten die ' kompilieren' aus 'slf4j' entfernen (Sie benötigen es auch zur Laufzeit). –

Warum ' kompilieren' für 'slf4j '? – Gangaraju

Ich entfernte kompilieren, aber ich bin mit dem gleichen Problem konfrontiert –

Sie benötigen eine andere Abhängigkeit hinzuzufügen, um das Problem zu lösen.

<!-- Logging with SLF4J & LogBack --> 
    <dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>slf4j-api</artifactId> 
     <version>${slf4j.version}</version> 
     <scope>compile</scope> 
    </dependency> 
<dependency> 
    <groupId>org.slf4j</groupId> 
    <artifactId>slf4j-log4j12</artifactId> 
    <version>${slf4j.version}</version> 
</dependency>

Fügen Sie eine weitere Abhängigkeit hinzu. Hoffe es wird dir helfen.
