log4j2 ERROR StatusLogger Spécificateur de conversion non reconnu

J'ai log4j2 dans mon projet lorsque j'exécute la méthode principale dans intellij Idea, il est correct d'imprimer le journal.

lorsque j'utilise le projet de package maven-shadow-plugin dans un fichier jar et que j'exécute jar en tant qu'application autonome, il affiche une erreur:

Java -cp package.jar com.xxx.TestMain

la sortie de la console

Si une dépendance contient le plug-in log4j2, un fichier de cache Log4j2Plugins.dat est inclus dans le bocal. Lorsque le plugin d'ombrage Maven est utilisé pour fusionner plusieurs pots avec un fichier Log4j2Plugins.dat, un seul survivra. Sans les définitions de plugin, des erreurs sont affichées au démarrage. problème Log4j2

Une solution consiste à exclure le fichier de cache Log4j2Plugins.dat du pot ombré afin que Log4j recherche les plugins au démarrage. Pour cela, ajoutez un filtre dans maven-shade-plugin configuration dans votre pom:

    <plugin>
        <groupId>org.Apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>3.1.0</version>
        <configuration>
            <createDependencyReducedPom>false</createDependencyReducedPom>
            <filters>
                <filter>
                    <artifact>*:*</artifact>
                    <excludes>
                        <exclude>**/Log4j2Plugins.dat</exclude>
                    </excludes>
                </filter>
            </filters>
        </configuration>
        ...
    </plugin>

Une autre solution consiste à fusionner les fichiers de cache à l'aide d'un plugin de transformation qui est spécifique à la version log4j.

J'ai déjà vu cette erreur lorsque les gens avaient plusieurs versions de Log4j2 sur le chemin de classe.
