日志使用http://www.iteye.com/topic/378077

补充 如何定义日志句柄：

private static Logger logger = LoggerFactory.getLogger("cons");
private static Logger logger = LoggerFactory.getLogger("file");

 

log4j.properties

log4j.logger.cons=info,appender1 
log4j.appender.appender1=org.apache.log4j.ConsoleAppender 
log4j.appender.appender1.layout=org.apache.log4j.PatternLayout 
log4j.appender.appender1.layout.ConversionPattern=[%d{yy/MM/dd HH:mm:ss:SSS}][%C-%M] %m%n
 
log4j.logger.file=info,appender2 
log4j.appender.appender2=org.apache.log4j.FileAppender 
log4j.appender.appender2.File=c:/Log4JDemo06.log 
log4j.appender.appender2.layout=org.apache.log4j.PatternLayout
log4j.appender.appender2.layout.ConversionPattern=[%d{HH:mm:ss:SSS}][%C-%M] -%m%n
