logback 配置

为了实现日志自动清理，所以使用了logback来代替log4j，话不多说，下面就是实现方式，是不是超级简单？

 

添加依赖包

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.5</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>1.0.11</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.0.11</version>
</dependency>

 配置logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<!-- 要使配置文件自动重载，需要把 scan 属性设置为 true，默认情况下每分钟才会扫描一次，可以指定扫描间隔：scanPeriod 可用的单位是 
	milliseconds，seconds，minutes 和 hours -->
<configuration scan="true" scanPeriod="60 seconds" debug="false">
	<!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径 -->
	<property name="LOG_HOME" value="./logs" />
	<property name="fileLayoutPattern"
		value="%-20(%d{yyyy-MM-dd HH:mm:ss.SSS} [%logger{50}][%thread] [%-4relative]) [%X{hostName} %X{requestId} %X{processId} %X{service.timing} ][%level] %msg%n" />
	<property name="consoleLayoutPattern"
		value="%-20(%d{yyyy-MM-dd HH:mm:ss.SSS} [%logger{50}][%thread] [%-4relative]) [%X{hostName} %X{requestId} %X{processId} %X{service.timing} ][%level] %msg%n" />

	<!-- 控制台输出 -->
	<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
		<layout name="StandardFormat" class="ch.qos.logback.classic.PatternLayout">

	<!-- 按照每天生成日志文件 -->
	<appender name="INFO"

		<file>${LOG_HOME}/info.log</file>
		<!-- 日志过滤器，只记录warn级别日志 ,若要配置其他级别，复制appender，修改level，并在root中配置 -->
		<filter class="ch.qos.logback.classic.filter.LevelFilter">

			<onMismatch>DENY</onMismatch>
		</filter>
		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
			<fileNamePattern>${LOG_HOME}/info.%d{yyyy-MM-dd}.log
			</fileNamePattern>
			<!--日志文件保留天数 -->
			<MaxHistory>30</MaxHistory>
		</rollingPolicy>
		<layout>
			<pattern>${fileLayoutPattern}</pattern>
		</layout>
	</appender>

	<appender name="ERROR"
		class="ch.qos.logback.core.rolling.RollingFileAppender">
		<file>${LOG_HOME}/error.log</file>
		<!-- 日志过滤器，只记录warn级别日志 ,若要配置其他级别，复制appender，修改level，并在root中配置 -->
		<filter class="ch.qos.logback.classic.filter.LevelFilter">

			<onMismatch>DENY</onMismatch>
		</filter>
		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

			</fileNamePattern>
			<!--日志文件保留天数 -->
			<MaxHistory>30</MaxHistory>
		</rollingPolicy>
		<layout>
			<pattern>${fileLayoutPattern}</pattern>
		</layout>
	</appender>


	<!-- 日志输出级别 -->
	<root level="INFO">
		<appender-ref ref="STDOUT" />
		<appender-ref ref="INFO" />
		<appender-ref ref="ERROR" />
	</root>
</configuration>

 

java代码

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Main {
     public static Logger log = LoggerFactory.getLogger(Main.class);

public static void main(String[] args) {
     log.info("哦了");
     log.error("额。。。。");
}
