Hi there, im trying to setup loggers programatically and noticed that
logback / log4j wont create the empty directory for you using
rollingfileappender. Here is what ive had to do to get the parent
directory recursively created because i wont be sure what the parent
directory of the logger will be until its created. Is there a better
way ?
LoggerContext lc = (LoggerContext)
logStats.getLoggerContext();
W3CAccessLayout layout = new W3CAccessLayout();
layout.setContext(lc);
layout.start();
RollingFileAppender<LoggingEvent> appender = new
RollingFileAppender<LoggingEvent>();
appender.setContext(lc);
appender.setImmediateFlush(true);
appender.setName(appenderName);
appender.setLayout(layout);
TimeBasedRollingPolicy policy = new TimeBasedRollingPolicy();
policy.setContext(lc);
policy.setFileNamePattern(path + logFilePattern);
policy.setParent(appender);
policy.setCurrentTime(System.currentTimeMillis());
policy.start();
File file = new File(policy.getNewActiveFileName());
File dir = new File(file.getParent());
dir.mkdirs();
appender.setRollingPolicy(policy);
appender.start();
logStats.addAppender(appender);
