一、pom.xml添加依赖

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    
    
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-log4j2</artifactId>
    </dependency>

二、创建log4j2.xml或log4j2-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
    
    
    
    
    <configuration status="warn" monitorInterval="30">
        
        <appenders>
            
            <console name="Console" target="SYSTEM_OUT">
                
                <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>
            </console>
            
            <File name="log" fileName="logs/test.log" append="false">
                <PatternLayout pattern="%d{HH:mm:ss.SSS} %-5level %class{36} %L %M - %msg%xEx%n"/>
            </File>
            
            <RollingFile name="RollingFileInfo" fileName="logs/info.log"
                         filePattern="logs/$${date:yyyy-MM}/info-%d{yyyy-MM-dd}-%i.log">
                <Filters>
                    
                    <ThresholdFilter level="INFO" onMatch="ACCEPT" onMismatch="DENY"/>
                    <ThresholdFilter level="WARN" onMatch="DENY" onMismatch="NEUTRAL"/>
                </Filters>
                <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>
                <Policies>
                    <TimeBasedTriggeringPolicy/>
                    <SizeBasedTriggeringPolicy size="100 MB"/>
                </Policies>
                
                <DefaultRolloverStrategy max="24"/>
            </RollingFile>
    
            <RollingFile name="RollingFileWarn" fileName="logs/warn.log"
                         filePattern="logs/$${date:yyyy-MM}/warn-%d{yyyy-MM-dd}-%i.log">
                <Filters>
                    <ThresholdFilter level="WARN" onMatch="ACCEPT" onMismatch="DENY"/>
                    <ThresholdFilter level="ERROR" onMatch="DENY" onMismatch="NEUTRAL"/>
                </Filters>
                <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>
                <Policies>
                    <TimeBasedTriggeringPolicy/>
                    <SizeBasedTriggeringPolicy size="100 MB"/>
                </Policies>
                
                <DefaultRolloverStrategy max="24"/>
            </RollingFile>
    
            <RollingFile name="RollingFileError" fileName="logs/error.log"
                         filePattern="logs/$${date:yyyy-MM}/error-%d{yyyy-MM-dd}-%i.log">
                <ThresholdFilter level="ERROR"/>
                <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>
                <Policies>
                    <TimeBasedTriggeringPolicy/>
                    <SizeBasedTriggeringPolicy size="100 MB"/>
                </Policies>
                
                <DefaultRolloverStrategy max="24"/>
            </RollingFile>
    
        </appenders>
        
        <loggers>
            
            <logger name="org.springframework" level="INFO">
            </logger>
            <logger name="org.mybatis" level="INFO">
            </logger>
            <root level="all">
                <appender-ref ref="Console"/>
                <appender-ref ref="RollingFileInfo"/>
                <appender-ref ref="RollingFileWarn"/>
                <appender-ref ref="RollingFileError"/>
            </root>
        </loggers>
    
    </configuration>

无须配置application.yml

logging:
      config: classpath:log4j2.xml

启动项目后，会在项目下新建一个logs的文件夹，下面有日志，刷新项目查看
