log4j配置详解（非常详细）
log4j配置详解（⾮常详细）Log4J的配置⽂件(Configuration File)就是⽤来设置记录器的级别、存放器和布局的，它可接key=value格式的设置或xml格式的设置信息。
通过配置，可以创建出Log4J的运⾏环境。
1. 配置⽂件Log4J配置⽂件的基本格式如下：2. 在代码中初始化Logger:1）在程序中调⽤BasicConfigurator.configure()⽅法：给根记录器增加⼀个ConsoleAppender，输出格式通过PatternLayout设为"%-4r [%t] %-5p %c %x - %m%n"，还有根记录器的默认级别是Level.DEBUG.2）配置放在⽂件⾥，通过命令⾏参数传递⽂件名字，通过PropertyConfigurator.configure(args[x])解析并配置；3）配置放在⽂件⾥，通过环境变量传递⽂件名等信息，利⽤log4j默认的初始化过程解析并配置；4）配置放在⽂件⾥，通过应⽤服务器配置传递⽂件名等信息，利⽤⼀个特殊的servlet来完成配置。
3. 为不同的 Appender 设置⽇志输出级别：当调试系统时，我们往往注意的只是异常级别的⽇志输出，但是通常所有级别的输出都是放在⼀个⽂件⾥的，如果⽇志输出的级别是BUG！？那就慢慢去找吧。
这时我们也许会想要是能把异常信息单独输出到⼀个⽂件⾥该多好啊。
当然可以，Log4j已经提供了这样的功能，我们只需要在配置中修改Appender的Threshold就能实现,⽐如下⾯的例⼦：运⾏⼀下，看看异常信息是不是保存在了⼀个单独的⽂件error.log中。

Maven项目配置log4j2.xml
Maven项⽬配置log4j2.xmllog4j2相对于log4j 1.x有了脱胎换⾻的变化，其官⽹宣称的优势有多线程下10⼏倍于log4j 1.x和logback的⾼吞吐量、可配置的审计型⽇志、基于插件架构的各种灵活配置等。
以下是log4j2在maven 项⽬中的配置步骤：1、在pom.xml⽂件中引⼊log4j依赖<!-- https:///artifact/org.apache.logging.log4j/log4j-core --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-core</artifactId><version>2.10.0</version></dependency><!-- https:///artifact/org.apache.logging.log4j/log4j-api --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-api</artifactId><version>2.10.0</version></dependency><!-- https:///artifact/org.apache.logging.log4j/log4j-web --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-web</artifactId><version>2.10.0</version></dependency><!-- https:///artifact/com.lmax/disruptor --><dependency><groupId>com.lmax</groupId><artifactId>disruptor</artifactId><version>3.4.1</version></dependency>2、配置log4j2.xml⽂件放置到src/main/resources⽬录下<?xml version="1.0" encoding="UTF-8"?><!--status : 这个⽤于设置log4j2⾃⾝内部的信息输出,可以不设置,当设置成trace时,会看到log4j2内部各种详细输出monitorInterval : Log4j能够⾃动检测修改配置⽂件和重新配置本⾝, 设置间隔秒数。
log4j2.xml 标准配置写法
一、概述log4j2是Apache Software Foundation的一个开源日志框架，广泛应用于Java应用程序的日志记录和管理。
在使用log4j2时，通常需要编写log4j2.xml文件进行配置。
本文将介绍log4j2.xml标准配置的写法，帮助读者更加有效地使用log4j2进行日志记录和管理。
二、log4j2.xml文件概述1. log4j2.xml是log4j2的配置文件，用于定义日志记录器、日志级别、输出目的地等配置信息。
2. log4j2.xml采用XML格式进行配置，通过定义各种元素和属性来实现对log4j2框架的配置和定制。
三、log4j2.xml标准配置写法在编写log4j2.xml文件时，可以按照以下标准配置进行操作：1. 配置根节点```xml<?xml version="1.0" encoding="UTF-8"?><Configuration status="WARN" monitorInterval="30"><!-- 配置日志级别、Appenders等信息 --></Configuration>```其中，根节点<Configuration>包含了两个属性：status和monitorInterval。
status属性用于设置全局日志级别，monitorInterval属性用于指定log4j2监视配置文件变化的时间间隔。
2. 配置日志级别```xml<Loggers><Root level="debug"><AppenderRef ref="Console"/><AppenderRef ref="File"/></Root></Loggers>```在<Loggers>节点下，可以通过<Root>节点配置全局日志级别，并通过<AppenderRef>节点引用Appenders进行输出。
log4j2.xml配置
log4j2.xml配置log4j1.*版本在打印日志的时候不支持占位符，在打印日志的时候需要拼接起来。
所以我就讲log4j版本改为 2.*，log4j2.*版本支持占位符，在代码看上去就美观了很多。
首先下载log4j包地址:/log4j/2.x/download.html将log4j-api-2.*.jar、log4j-core-2.*.jar包放入lib文件夹下创建配置文件log4j 2.*有xml、json配置两种文件方式，并没有1.*版本的properties配置方式下面就以xml配置方式为例在src下创建一个log4j2.xml文件，注意是log4j2.xml内容如下：Java代码1.<?xml version="1.0" encoding="UTF-8"?>2.<configuration status="off">3.<Properties>4.<Property name="LOG_HOME">${sys:catalina.home}/log s/AppNetAgeService</Property>5.<Property name="LOG_NAME">log.txt</Property>6.</Properties>7.<appenders>8.<Console name="Console" target="SYSTEM_OUT">9.<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} %-5level [%thread][%file:%line] - %msg%n"/>10.</Console>11.<RollingFile name="log" fileName="${LOG_HOME}/${ LOG_NAME}" filePattern="${LOG_HOME}/${LOG_NAME}.%d{yyy y-MM-dd}" append="true">12.<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} %-5level [%thread][%file:%line] - %msg%n" />13.<Policies>14.<TimeBasedTriggeringPolicy modulate="true" interval ="1" />15.</Policies>16.<DefaultRolloverStrategy max="180" />17.</RollingFile>18.</appenders>19.<loggers>20.<root level="DEBUG">21.<appender-ref ref="Console"/>22.<appender-ref ref="log"/>23.</root>24.</loggers>25.</configuration>注意事项：1、<root level="DEBUG"></root>这个标签中level等级，、log4j优先级分别为FATAL、ERROR、WARN、INFO、DEBUG, 如果level的值设置为ERROR,那么只有FATAL、ERROR等级的日志才会打印2、 <Property name="LOG_HOME">${sys:catalina.home}/logs/AppNetAgeSer vice</Property>，1.*版本中获取tomcat路径是${catalina.home}，log4j2.*版本中获取tomcat路径是${sys:catalina.home}3、要在<root>标签中添加<appender-ref ref="Console"/>,<appender-ref ref="log"/>才能在控制台、和文件中打印日志4、RollingFile标签参数说明：4.1:、append这个参数是是否将日志追加的方式打印，如果为false时，tomcat重新后，log.txt这里原有的日志就会清空，如果为true时，tomcat重启后，log.txt日志不会清空4.2、TimeBasedTriggeringPolicy标签的interval属性是每天生成一个日志文件，RollingFile标签的filePttern属性是备份文件的格式。
log4j.xml配置实现
log4j.xml配置实现先写一个Servlet的listener，用来监听服务启动，并自动解析log4j.xml文件代码如下：import javax.servlet.ServletContextEvent;import javax.servlet.ServletContextListener;import org.apache.log4j.LogManager;import org.apache.log4j.PropertyConfigurator;import org.apache.log4j.xml.DOMConfigurator;public class Log4jConfigListener implements ServletContextListener{public static final String CONFIG_LOCATION_PARAM = "log4jConfigLocation";public static final String XML_FILE_EXTENSION = ".xml";public void contextDestroyed(ServletContextEvent event) {// TODO Auto-generated method stubLogManager.shutdown();}public void contextInitialized(ServletContextEvent event) {// TODO Auto-generated method stubString location = event.getServletContext().getInitParameter(CONFIG_LOCATION_PARAM); if (location != null) {if (!location.startsWith("/")) {location = "/" + location;}location = event.getServletContext().getRealPath(location);//如果是xml结尾就用DOM解析，否则就用properties解析if (location.toLowerCase().endsWith(XML_FILE_EXTENSION)) {DOMConfigurator.configure(location);}else {PropertyConfigurator.configure(location);}}}}再写个util类，用来生成所要的不同类型的日志代码如下：package com.zhaopin.util;import org.apache.log4j.Logger;public class Log4jUtil {public static Logger getSQLLogger(){return Logger.getLogger("sql");}public static Logger getBusinessLogger(){return Logger.getLogger("business");}public static Logger getSimpleErrorLogger(){return Logger.getLogger("simpleError");}public static Logger getNormalErrorLogger(){return Logger.getLogger("normalError");}}下面开始写配置文件，先要在web.xml下添加信息：<context-param><param-name>log4jConfigLocation</param-name><param-value>/WEB-INF/Log4j.xml</param-value></context-param><!-- 加载log4j配置文件--><listener><listener-class>Log4jConfigListener</listener-class></listener>最重要的log4j.xml的配置信息如下：<?xml version="1.0" encoding="GBK"?><!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"><log4j:configuration xmlns:log4j="/log4j/"><appender name="STDOUT" class="org.apache.log4j.ConsoleAppender"> <param name="target" value="System.out"/><layout class="org.apache.log4j.PatternLayout"><param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c] (%C:%L) - %m%n"/></layout></appender><!-- SQL类日志--><appender name="sql" class="org.apache.log4j.DailyRollingFileAppender"><param name="File" value="/usr/local/tomcat/logs/testlog4j.sql.log"/><param name="Append" value="true"/><!-- name="DatePattern"配置这条信息是让日志每天自动生成，名字尾部追加日期格式，第一天生成的日志需第二天才能看到log可以通过更改系统时间来看日志的输出--><param name="DatePattern" value="'.'yyyy-MM-dd"/><layout class="org.apache.log4j.PatternLayout"><param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c] (%C:%L) - %m%n"/></layout></appender><!-- 业务类日志--><appender name="business" class="org.apache.log4j.DailyRollingFileAppender"><param name="File" value="/usr/local/tomcat/logs/testlog4j.business.log"/><param name="Append" value="true"/><param name="DatePattern" value="'.'yyyy-MM-dd"/><layout class="org.apache.log4j.PatternLayout"><param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c] (%C:%L) - %m%n"/></layout></appender><!-- 不带执行轨迹错误日志--><appender name="simpleError" class="org.apache.log4j.DailyRollingFileAppender"><param name="File" value="/usr/local/tomcat/logs/testlog4j.error.simple.log"/><param name="Append" value="true"/><param name="DatePattern" value="'.'yyyy-MM-dd"/><layout class="org.apache.log4j.PatternLayout"><param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c] (%C:%L) - %m%n"/></layout></appender><!-- 带执行轨迹错误日志--><appender name="normalError" class="org.apache.log4j.DailyRollingFileAppender"><param name="File" value="/usr/local/tomcat/logs/testlog4j.error.normal.log"/><param name="Append" value="true"/><param name="DatePattern" value="'.'yyyy-MM-dd"/><layout class="org.apache.log4j.PatternLayout"><param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c] (%C:%L) - %m%n"/></layout></appender><logger name="sql" additivity="true"><priority value="info"/><appender-ref ref="sql"/></logger><logger name="business" additivity="true"><priority value="info"/><appender-ref ref="simpleError"/></logger><logger name="simpleError" additivity="true"><priority value="info"/><appender-ref ref="simpleError"/></logger><logger name="normalError" additivity="true"><priority value="info"/><appender-ref ref="normalError"/></logger><root><appender-ref ref="STDOUT"/><priority value="info"/></root></log4j:configuration>在程序中应用时需要编写如下代码:Log4jUtil.getBusinessLogger().info("message!");。
