Impossible d'initialiser une instance de org.apache.velocity.runtime.log.Log4JLogChute avec la configuration d'exécution en cours

Question

Je travaille sous linux, dans ma demande, je la permission limitée et tout chemin sera lu que

dans ma demande que j'ai utilisé vitesse-1.6.2.jar et à chaque fois quand il est appelé à créer velocity.log et ce fichier doit être en lecture/écriture.

pour ce problème que je tente de désactiver diagraphie de vitesse

J'essaie d'ajouter cette ligne dans propriétés de vitesse:

runtime.log.logsystem.class=org.apache.velocity.runtime.log.NullLogSystem 

mais je cette erreur:

org.apache.velocity.exception.VelocityException: Failed to initialize an instance of org.apache.velocity.runtime.log.Log4JLogChute with the current runtime configuration.

Answer 1

Vous utilisez NullLogChute qui est un Deprecated class, si vous voulez vraiment

Enregistreur utilisé en cas de défaillance. Ne fait rien.

utilisation org.apache.velocity.runtime.log.NullLogChute, dans velocity.properties:

runtime.log.logsystem.class=org.apache.velocity.runtime.log.NullLogChute 

Voir aussi dependencies pour la vitesse 1.6.2 et vérifiez que vous disposez des versions pertinentes.
