首先看一下springboot官方文档： [https://docs.spring.io/spring-boot/docs/1.5.19.RELEASE/reference/htmlsingle/\#howto-configure-log4j-for-logging][https_docs.spring.io_spring-boot_docs_1.5.19.RELEASE_reference_htmlsingle_howto-configure-log4j-for-logging]

# 开始配置 #

在pom.xml里面加入这个

<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>

然后resources里新建一个文件 log4j2.xml，内容如下

<?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="log/test.log" append="false">
                <PatternLayout pattern="%d{HH:mm:ss.SSS} %-5level %class{36} %L %M - %msg%xEx%n"/>
            </File>
            
            <RollingFile name="RollingFileInfo" fileName="${sys:user.home}/logs/yyw/info.log"
                         filePattern="${sys:user.home}/logs/yyw/$${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>
            </RollingFile>
    
            <RollingFile name="RollingFileWarn" fileName="${sys:user.home}/logs/yyw/warn.log"
                         filePattern="${sys:user.home}/logs/yyw/$${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="20"/>
            </RollingFile>
    
            <RollingFile name="RollingFileError" fileName="${sys:user.home}/logs/yyw/error.log"
                         filePattern="${sys:user.home}/logs/yyw/$${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>
            </RollingFile>
    
        </appenders>
        
        <loggers>
            
            <logger name="org.springframework" level="INFO"/>
            <logger name="org.eclipse.jetty" level="INFO"/>
            <logger name="org.mybatis" level="INFO"/>
            <root level="all">
                <appender-ref ref="Console"/>
                <appender-ref ref="RollingFileInfo"/>
                <appender-ref ref="RollingFileWarn"/>
                <appender-ref ref="RollingFileError"/>
            </root>
        </loggers>
    </configuration>

然后在application.yml文件里指定一下配置文件

logging:
      config: classpath:log4j2.xml

然后运行就OK了
