Re: [logback-user] programmatic configuration to log to file

1 Feb 2013

      Hi Steve,

The code for programmatic configuration is good. You just need to reset 
the context before you configure. Add the following line after the 
definitionof the loggerContext variable.

   loggerContext.reset();

HTH,

Is it the same output that is also showing up in the log file, or
other output? Can you provide a more complete code sample with file
output and stdout output?

Here is the complete source code (no config files at all):
package com.geekster.logbackDemo;
import org.slf4j.LoggerFactory;
import ch.qos.logback.classic.Logger;
import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.PatternLayout;
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.FileAppender;
public class Testcase {
public static void main(String[] args) {
       LoggerContext loggerContext = (LoggerContext)
LoggerFactory.getILoggerFactory();
FileAppender<ILoggingEvent> fileAppender = new
FileAppender<ILoggingEvent>();
       fileAppender.setContext(loggerContext);
       fileAppender.setFile(Testcase.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();
Logger logbackLogger = loggerContext.getLogger(Testcase.class);
       logbackLogger.addAppender(fileAppender);
logbackLogger.info("this should only be in the logfile.");
       System.out.println("this should only be at the console");
    }
}
Here is what gets written to System.out:
12:57:07.496 [main] INFO  com.geekster.logbackDemo.Testcase - this
should only be in the logfile.
this should only be at the console
Here is what gets written to Testcase.log:
2013-02-01 12:57:07,496  INFO main
[com.geekster.logbackDemo.Testcase:31] this should only be in the logfile.
So what I'm looking to do is to have the log entry "12:57:07.496 [main]
INFO com.geekster.logbackDemo.Testcase - this should only be in the
logfile." only appear in the logfile, but not at the console where I
only expect "this should only be at the console" to be visible.
Thanks for looking.
Steve
