간단한 log4j 설정

 log4j.properties:

log4j.rootLogger=ERROR, logfile,console
log4j.logger.com.opensymphony.xwork2=error, logfile
log4j.logger.org.hibernate.cfg=ERROR,console,logfile

log4j.appender.logfile=org.apache.log4j.RollingFileAppender
log4j.appender.logfile.File=D\:\\markertlog\\log4j.log
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=[%-5p] %d{HH:mm:ss} [%c{1}] - %m%n

# 
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=[%-5p] %d{HH:mm:ss} [%c{1}] - %m%n 

 
 
 
A.java에서 호출하는 경우:
private transient final Log logger = LogFactory.getLog(A.class);
방법에서logger를 사용할 수 있습니다.error("..................");
