1、Spring Boot默认使用slf4j+logback日志框架。如果要自定义logback日志则需要在项目的资源路径下添加logback.xml文件。logback.xml内容如下：

<?xml version="1.0" encoding="UTF-8"?>
    
    <configuration scan="false" scanPeriod="60 seconds" debug="false">
        
        <property name="LOG_HOME" value="/logs/log" />
        
        <property name="appName" value="mengxuegu-spring-boot"></property>
        
        <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
            
            <layout class="ch.qos.logback.classic.PatternLayout">
                <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} - [%thread] - %-5level - %logger{50} - %msg%n</pattern>
            </layout>
        </appender>
    
          
        <appender name="appLogAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
            
            <file>${LOG_HOME}/${appName}.log</file>
            
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                
                <fileNamePattern>${LOG_HOME}/${appName}-%d{yyyy-MM-dd}-%i.log</fileNamePattern>
                
                <MaxHistory>365</MaxHistory>
                
                <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                    <maxFileSize>100MB</maxFileSize>
                </timeBasedFileNamingAndTriggeringPolicy>
            </rollingPolicy>
                 
            <layout class="ch.qos.logback.classic.PatternLayout">
                <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [ %thread ] - [ %-5level ] [ %logger{50} : %line ] - %msg%n</pattern>
            </layout>
        </appender>
    
        
        
        <logger name="com.mengxuegu" level="debug" />
        
        <logger name="org.springframework" level="debug" additivity="false"></logger>
    
    
        
        <root level="info">
            <appender-ref ref="stdout" />
            <appender-ref ref="appLogAppender" />
        </root>
    </configuration>

2、也可以添加logback-spring.xml文件，logback-spring.xml比logback.xml多了一个可以根据环境来设置日志的标签，如下：

3、如果要切换Spring Boot的默认日志框架，首先把它原有的日志框架移除，然后再引入新的框架，比如使用log4j2框架

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