Based on some examples I cobbled together the following code to programmatically
configure logback to write its output to a file (I don't like having config
files around), but the output still goes to stdout in addition to the file. Can
anyone give me a clue how I can only have the output go to the specific file and
not stdout?
Thanks
Steve
LoggerContext loggerContext = (LoggerContext)
LoggerFactory.getILoggerFactory();
FileAppender<ILoggingEvent> fileAppender = new
FileAppender<ILoggingEvent>();
fileAppender.setContext(loggerContext);
fileAppender.setFile(ConcurrencyExample.class.getSimpleName() + ".log");
PatternLayout pl = new PatternLayout();
pl.setPattern("%d %5p %t [%c:%L] %m%n)");
pl.setContext(loggerContext);
pl.start();
fileAppender.setLayout(pl);
fileAppender.start();
// attach the rolling file appender to the logger of your choice
Logger logbackLogger = loggerContext.getLogger(ConcurrencyExample.class);
logbackLogger.addAppender(fileAppender);
// OPTIONAL: print logback internal status messages
StatusPrinter.print(loggerContext);
// log something
logbackLogger.info("hello");
