FileAppender appender = new FileAppender();
// configure the appender here, with file location, etc
appender.activateOptions();

Logger logger = getRootLogger();
logger.addAppender(appender);

代码示例来源：origin: stackoverflow.com

ConsoleAppender console = new ConsoleAppender(); //create appender
//configure the appender
String PATTERN = "%d [%p|%c|%C{1}] %m%n";
console.setLayout(new PatternLayout(PATTERN)); 
console.setThreshold(Level.FATAL);
console.activateOptions();
//add appender to any Logger (here is root)
Logger.getRootLogger().addAppender(console);
FileAppender fa = new FileAppender();
fa.setName("FileLogger");
fa.setFile("mylog.log");
fa.setLayout(new PatternLayout("%d %-5p [%c{1}] %m%n"));
fa.setThreshold(Level.DEBUG);
fa.setAppend(true);
fa.activateOptions();
//add appender to any Logger (here is root)
Logger.getRootLogger().addAppender(fa);
//repeat with all other desired appenders
