1、maven加载依赖

		<dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-api</artifactId>
            <version>2.20.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-core</artifactId>
            <version>2.20.0</version>
        </dependency>

2、配置log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
    <Properties>
        <property name="basePath">./Log/log4j2</property>
        <property name="console_log_pattern">%d{yyyy-MM-dd HH:mm:ss.SSS} [%-5level] %l - %m%n</property>
        <property name="log_pattern">%d{yyyy-MM-dd HH:mm:ss.SSS} [%-5level] %C.%M[%L line] - %m%n</property>
        <!-- 日志默认切割的最小单位 -->
        <property name="every_file_size">10MB</property>
        <!-- 日志默认输出级别 -->
        <property name="output_log_level">DEBUG</property>

        <!-- 日志默认存放路径(所有级别日志) -->
        <property name="rolling_fileName">${basePath}/all.log</property>
        <property name="rolling_filePattern">${basePath}/all-%d{yyyy-MM-dd}-%i.log.gz</property>
        <property name="rolling_max">7</property>
        <property name="rolling_timeInterval">1</property>
        <property name="rolling_timeModulate">true</property>

        <!-- Info日志默认存放路径(Info级别日志) -->
        <property name="info_fileName">${basePath}/info.log</property>
        <property name="info_filePattern">${basePath}/info-%d{yyyy-MM-dd}-%i.log.gz</property>
        <property name="info_max">7</property>
        <property name="info_timeInterval">1</property>
        <property name="info_timeModulate">true</property>

    </Properties>
    <Appenders>
        <!--  控制台输出-->
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="${console_log_pattern}"/>
        </Console>

        <RollingFile name="RollingFile" fileName="${rolling_fileName}" filePattern="${rolling_filePattern}">

                <SizeBasedTriggeringPolicy size="${every_file_size}"/>
            </Policies>
            <DefaultRolloverStrategy max="${info_max}" />
            <Filters>

            </Filters>
        </RollingFile>

    </Appenders>
    <Loggers>
        <!-- 设置包的级别 -->
        <Logger name="com" level="${output_log_level}"/>
        <!-- 总日志级别 -->
        <Root level="debug">
            <AppenderRef ref="Console"/>
            <AppenderRef ref="RollingFile"/>
            <AppenderRef ref="InfoFile"/>
        </Root>
    </Loggers>
</Configuration>
