log4j、logback汇总

log4j 参考 配置Log4j(很详细) 和 Log4j按级别输出到不同文件。

主要是重写 DailyRollingFileAppender 

logback配置参考

<?xml version="1.0" encoding="UTF-8"?>

<configuration debug="true">

	<property resource="application.properties" />

	<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
		<encoder charset="UTF-8">
			<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
		</encoder>
	</appender>

	<appender name="FILE-ERROR"	class="ch.qos.logback.core.rolling.RollingFileAppender">
		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
			<fileNamePattern>${log.root.folder}/error.log.%d{yyyy-MM-dd}</fileNamePattern>
			<maxHistory>15</maxHistory>
		</rollingPolicy>
		<filter class="ch.qos.logback.classic.filter.LevelFilter">

      		<onMatch>ACCEPT</onMatch>

		</filter>
		<encoder>
			<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>

*********** 20161102 补充 ***********

logback提供了3种filter：LevelFilter、ThresholdFilter和EvalutorFilter。同时支持自定义filter。

比如为了方便日志调阅，我将项目包下面的日志独立出来。

import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.filter.Filter;
import ch.qos.logback.core.spi.FilterReply;

/**
 * Description:
 * Auth:Paris
 * Date:Nov 2, 2016
**/
public class ProjectFilter extends Filter<ILoggingEvent>{

	@Override
	public FilterReply decide(ILoggingEvent event) {
		if (event.getLoggerName().equals("xxx")){
			return FilterReply.ACCEPT;
		}else {
			return FilterReply.DENY;
		}
	}

}

import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.filter.Filter;
import ch.qos.logback.core.spi.FilterReply;

/**
 * Description:
 * Auth:Paris
 * Date:Nov 2, 2016
**/
public class ProjectDenyFilter extends Filter<ILoggingEvent>{

	@Override
	public FilterReply decide(ILoggingEvent event) {
		if (event.getLoggerName().equals("xxx")){
			return FilterReply.DENY;
		}else {
			return FilterReply.ACCEPT;
		}
	}

}

logger配置如下
