Dieser Code fungiert lediglich als Beispiel. Wenn Sie ihn in Ihr System kopieren, vergessen Sie nicht,
MY_EXTERNAL_FOLDER zu dem Verzeichnis umzuändern, in dem Sie die Logs speichern möchten, z. B.
/home/usr/my-re-log in Linux oder
D:/remote-engine/my-log-folder in Windows.
Der Teil $\\{ctx:flowID\\}/$\\{ctx:flowExecutionId\\} entspricht den für die Benennung der Logdateien zu verwendenden Variablen. Wenn Sie keinen dynamisch generierten Logdatei-Namen benötigen, ersetzen Sie ihn durch Klartext.
Nach diesen Änderungen sehen die Zeilen
log4j2.appender.external.routes.route1.rolling.fileName und
log4j2.appender.external.routes.route1.rolling.filePattern folgendermaßen aus:
- In Windows:
log4j2.appender.external.routes.route1.rolling.fileName = C:/my-personal-folder/my-log-foler/my-log.log
log4j2.appender.external.routes.route1.rolling.filePattern = C:/my-personal-folder/my-log-foler/my-log.log.%i
- In Linux:
log4j2.appender.external.routes.route1.rolling.fileName = /home/usr/my-re-log/my-log.log
log4j2.appender.external.routes.route1.rolling.filePattern = /home/usr/my-re-log/my-log.log.%i
