J'essaye d'ajouter un DB Appender dans ma configuration de logback. Voici la partie du fichier logback.xml lié à la question:logback. classe not found exception
<appender name="db" class="src.main.java.database.SqliteLogbackAppender">
<connectionSource class="ch.qos.logback.core.db.DriverManagerConnectionSource">
<driverClass>org.sqlite.JDBC</driverClass>
<url>jdbc:sqlite:/home/db/logger.db</url>
</connectionSource>
</appender>
La chose est, j'utiliser un appender personnalisé, qui est situé dans ma scr.main.java ... etc dossier , mais pas dans bibliothèque logback classique
quand je lance mon application, je reçois l'erreur suivante:
09:02:06,682 |-ERROR in [email protected]:78 - ActionException in Action for tag [appender] ch.qos.logback.core.joran.spi.ActionException: ch.qos.logback.core.util.DynamicClassLoadingException: Failed to instantiate type src.main.java.database.SqliteLogbackAppender

Cependant, quand j'écris sur classpath logback.xml configuration, je suis en mesure d'accéder au fichier avec l'interface IDE IntellijIdea (en cliquant sur ctrl + left_mouse_button), donc je crois qu'il n'y a pas de fautes de frappe.
Cordialement.
Merci à tous! C'était exactement le problème! – Vittori0
