tomcat使用log4j2打日志

开始前准备
1. tomcat版本8.0.51
(下载地址:http://archive.apache.org/dist/tomcat/tomcat-8/v8.0.51/bin/apache-tomcat-8.0.51.tar.gz) 2018-05-09可以访问
2. tomcat日志扩展接口包
tomcat-juli.jar
tomcat-juli-adapters.jar
(下载地址:http://archive.apache.org/dist/tomcat/tomcat-8/v8.0.51/bin/extras/) 2018-05-09可以访问
3. log4j2版本2.3
log4j-core-2.3.jar
log4j-api-2.3.jar
log4j-1.2-api-2.3.jar
(下载地址:http://www.apache.org/dist/logging/log4j/2.3/apache-log4j-2.3-bin.zip) 2018-05-09可以访问
(三个jar都在bin压缩包里)
4. 新建log4j2.xml


<Configuration status="info">
    <Properties>
        <Property name="logdir">${sys:catalina.base}/logsProperty>
        <Property name="layout">%d [%t] %-5p %c-%m%nProperty>
    Properties>
    <Appenders>
        <Console name="CONSOLE" target="SYSTEM_OUT">
            <PatternLayout charset="UTF-8" pattern="${layout}" />
        Console>
        <RollingFile name="CATALINA" fileName="${logdir}/catalina.log"
            filePattern="${logdir}/catalina.%d{yyyy-MM-dd}.log.gz">
            <PatternLayout charset="UTF-8" pattern="${layout}" />
            
            <SizeBasedTriggeringPolicy size="50MB" />
            <DefaultRolloverStrategy max="20" />
        RollingFile>
        <RollingFile name="LOCALHOST" fileName="${logdir}/localhost.log"
            filePattern="${logdir}/localhost.%d{yyyy-MM-dd}-%i.log.gz">
            <PatternLayout charset="UTF-8" pattern="${layout}" />
            <SizeBasedTriggeringPolicy size="50MB" />
            <DefaultRolloverStrategy max="20" />
        RollingFile>
    Appenders>
    <Loggers>
        <Logger
            name="org.apache.catalina.core.ContainerBase.[Catalina].[localhost]"
            level="info">
            <AppenderRef ref="LOCALHOST" />
        Logger>
        <Root level="info">
            <AppenderRef ref="CATALINA" />
            <AppenderRef ref="CONSOLE" />
        Root>
    Loggers>
Configuration>

操作
1. jar包
三个 log4j2 的jar包 和 tomcat-juli-adapters.jar放到 tomact 目录下的lib文件夹下
tomcat-juli.jar 替换tomcat目录下 bin 文件夹下的同名文件
2. 配置文件
删除或重命名tomact目录下conf文件夹下的logging.properties文件
log4j2.xml,放到tomcat目录下lib文件夹下

启动tomcat,在tomcat目录下logs文件夹下查看日志文件
