log4j 日志分级处理

log4j 配置文件:

log4j.rootLogger=debug,stdout,debug,info,error
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%-5p] [%d{HH:mm:ss}] %c - %m%n

log4j.logger.info=info
log4j.appender.info=com.ctcti.webExtensioncallcenter.utils.Appender
#log4j.appender.info =org.apache.log4j.DailyRollingFileAppender
log4j.appender.info.layout=org.apache.log4j.PatternLayout
log4j.appender.info.layout.ConversionPattern=[%-5p] [%d{HH:mm:ss}] %c - %m%n
log4j.appender.info.datePattern='.'yyyy-MM-dd
log4j.appender.info.Threshold = INFO
log4j.appender.info.append=true
log4j.appender.info.File=../logs/info.txt

log4j.logger.debug=debug
log4j.appender.debug=com.ctcti.webExtensioncallcenter.utils.Appender
#log4j.appender.debug =org.apache.log4j.DailyRollingFileAppender
log4j.appender.debug.layout=org.apache.log4j.PatternLayout
log4j.appender.debug.layout.ConversionPattern=[%-5p] [%d{HH:mm:ss}] %c - %m%n
log4j.appender.debug.datePattern='.'yyyy-MM-dd
log4j.appender.debug.Threshold = DEBUG
log4j.appender.debug.append=true
log4j.appender.debug.File=../logs/debug.txt

log4j.logger.error=error
log4j.appender.error=com.ctcti.webExtensioncallcenter.utils.Appender
#log4j.appender.error =org.apache.log4j.DailyRollingFileAppender
log4j.appender.error.layout=org.apache.log4j.PatternLayout
log4j.appender.error.layout.ConversionPattern=[%-5p] [%d{HH:mm:ss}] %c - %m%n
log4j.appender.error.datePattern='.'yyyy-MM-dd
log4j.appender.error.Threshold = ERROR
log4j.appender.error.append=true
log4j.appender.error.File=../logs/error.txt
log4j.appender.FILELOGER.encoding=UTF-8

log4j 等级区分配置

log4j.appender.info.Threshold = INFO

修改log4j 输出日志的类型，重写它里面的区分等级方法

public class Appender extends DailyRollingFileAppender{

@Override
public boolean isAsSevereAsThreshold(Priority priority) {
//只判断是否相等，而不判断优先级
return this.getThreshold().equals(priority);
}
}

这样日志就会按等级区分啦。
