how can i disable the default console handler, while using the java logging api ?
- by loudiyimo
Hi I am trying to implement the java logging in my application. I want to use two handlers.
A file handler and my own console handler. Both of my handlers work fine. My logging is send to a file and to the console .
My logging is also sent to the default console handler, which i do not want. If you run my code you will see extra two line sent to the console. I don't want to use de default console handler. Does anyone know how to disable the default console handler.
I only want to use the two hadlers i have created.
Handler fh = new FileHandler("test.txt");
fh.setFormatter(formatter);
logger.addHandler(fh);
Handler ch = new ConsoleHandler();
ch.setFormatter(formatter);
logger.addHandler(ch);
import java.util.Date;
import java.util.logging.ConsoleHandler;
import java.util.logging.FileHandler;
import java.util.logging.Formatter;
import java.util.logging.Handler;
import java.util.logging.Level;
import java.util.logging.LogManager;
import java.util.logging.LogRecord;
import java.util.logging.Logger;
public class LoggingExample {
private static Logger logger = Logger.getLogger("test");
static {
try {
logger.setLevel(Level.INFO);
Formatter formatter = new Formatter() {
@Override
public String format(LogRecord arg0) {
StringBuilder b = new StringBuilder();
b.append(new Date());
b.append(" ");
b.append(arg0.getSourceClassName());
b.append(" ");
b.append(arg0.getSourceMethodName());
b.append(" ");
b.append(arg0.getLevel());
b.append(" ");
b.append(arg0.getMessage());
b.append(System.getProperty("line.separator"));
return b.toString();
}
};
Handler fh = new FileHandler("test.txt");
fh.setFormatter(formatter);
logger.addHandler(fh);
Handler ch = new ConsoleHandler();
ch.setFormatter(formatter);
logger.addHandler(ch);
LogManager lm = LogManager.getLogManager();
lm.addLogger(logger);
}
catch (Throwable e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
logger.info("why does my test application use the standard console logger ?\n" +
" I want only my console handler (Handler ch)\n " +
"how can i turn the standard logger to the console off. ??");
}
}
