Pour développer un nouveau projet, j'ai utilisé Springboot comme framework. Lors du développement du projet, j'ai utilisé Eclipse pour les tests. J'ai découvert ce problème récemment alors que je me préparais à le déployer sur le Tomcat8 local. développement client. Plus précisément, l’exception est la suivante :

Caused by: java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.apache.logging.slf4j.Log4jLoggerFactory loaded from file:/C:/server/apache-tomcat-8.5.15/webapps/ucwapi/WEB-INF/lib/log4j-slf4j-impl-2.4.1.jar).
