Logging slf4j configuration through code.

[archit thakur]

Hi,

I am trying to use slf4j and logback libraries for logging in my project. I want to do the configuration through code rather than through xml.

LoggerContext loggerContext = (LoggerContext)LoggerFactory.getILoggerFactory();
			RollingFileAppender rollingFileAppender = new RollingFileAppender();
			rollingFileAppender.setName("Exporter");
			rollingFileAppender.setFile("logFile.log");
			rollingFileAppender.setContext(loggerContext);

TimeBasedRollingPolicy timeBasedRollingPolicy = new TimeBasedRollingPolicy();
			timeBasedRollingPolicy.setFileNamePattern("logFile.%d{yyyy-MM-dd}.log");
			timeBasedRollingPolicy.setMaxHistory(30);
			rollingFileAppender.setRollingPolicy(timeBasedRollingPolicy);

			PatternLayoutEncoder patternLayoutEncoder = new PatternLayoutEncoder();
			patternLayoutEncoder.setPattern("[%d] %-5level %logger{35} - %msg%n");
			rollingFileAppender.setEncoder(patternLayoutEncoder);

                        Logger localLogger = loggerContext.getLogger("Exporter");
			localLogger.addAppender(rollingFileAppender);
			localLogger.setLevel(ALL);

and afetrwards, I am catching localLoger in

org.slf4j.Logger logger = localLogger

. and then using it for logging via

logger.debug

. Idea about where I have got wrong it is not making the new file logFile.log, and printing log messages on screen.

Archit,

Please DontWriteLongLines (←click), because it makes your thread very hard to read. I suggest that you use the 'Edit' key to break them up; I'd do it myself, but there's a lot of them.

Thanks
