Hello everyone, I am trying to specify the size of my log file in my Java code. However, no file is written in the specified directory. Using a FileAppender without a triggering policy works fine. But I would like to specify the max. log file size. Any help is appreciated :) Thanx in advance! Here is my code: LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory(); RollingFileAppender<ILoggingEvent> fileAppender = new RollingFileAppender<ILoggingEvent>(); fileAppender.setContext(loggerContext); fileAppender.setFile("C:\\log\\log.txt"); SizeBasedTriggeringPolicy<ILoggingEvent> triggeringPolicy = new SizeBasedTriggeringPolicy<ILoggingEvent>(); triggeringPolicy.setMaxFileSize("5MB"); triggeringPolicy.start(); PatternLayoutEncoder encoder = new PatternLayoutEncoder(); encoder.setContext(loggerContext); encoder.setPattern("%d %level %logger: %msg%n"); encoder.start(); fileAppender.setEncoder(encoder); fileAppender.setTriggeringPolicy(triggeringPolicy); fileAppender.start(); Logger logbackLogger = loggerContext.getLogger("ExportMapToFile"); ((ch.qos.logback.classic.Logger) logbackLogger).addAppender(fileAppender); logbackLogger.info(info); fileAppender.stop(); triggeringPolicy.stop(); encoder.stop();
