Here I'll show you my logback configuration useful to avoid this problem and grep the log easily.
%-30(%d [%thread]) %-5level %logger{16} - %replace(%msg){'\n','|'} %xEx%n
The class below produces logs like this. Too bad that even if you try to log in single line the Exception stack trace adding '%replace' in %xEx, it works only for the first stack trace line, if you have a solution please tell me.
package com.googlecode.log.pretty;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class App {
private static final Logger log = LoggerFactory.getLogger(App.class);
public static void main(String[] args) {
log.info("Hello World!");
String message = "I'm a message\nI m a new line\n\tI'm a tabbed new line";
log.trace(message);
log.debug(message);
log.info(message);
log.warn(message);
log.error(message);
log.error("I'm an error", new Exception("To see stackTrace"));
}
}
