動的配置Log 4 j

1.導入のインスタンス化

PatternLayout layout = new PatternLayout("[%d{yyyy-MM-dd HH:mm:ss}][%p][%l] - %m%n");
ConsoleAppender consoleAppender=new ConsoleAppender(layout);
consoleAppender.setTarget("System.out");

DailyRollingFileAppender dailyRollingFileAppender=new DailyRollingFileAppender(layout, "./logs", "'.'yyyy-MM-dd'.log'");
dailyRollingFileAppender.setName("DailyRollingFile");
dailyRollingFileAppender.setAppend(true);

Logger logger=Logger.getLogger(cls.getName());
logger.addAppender(consoleAppender);
logger.addAppender(dailyRollingFileAppender);

logger.debug("ok");

 
2.プロファイル配置の指定

PropertyConfigurator.configure(".\\src\\main\\conf\\log4j.properties");
Logger logger=Logger.getLogger(cls.getName());
logger.debug("ok");
