log4j、logback彙總

log4j 參考 配置Log4j(很詳細) 和 Log4j按級別輸出到不同文件。

主要是重寫 DailyRollingFileAppender 

logback配置參考

<?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>

*********** 20161102 補充 ***********

logback提供了3種filter：LevelFilter、ThresholdFilter和EvalutorFilter。同時支持自定義filter。

比如爲了方便日誌調閱，我將項目包下面的日誌獨立出來。

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
