概要
springboot默认选用的框架是 slf4j+logback。
使用
Springboot默认配置好了日志框架，直接使用即可。
配置
Springboot的jar包中包含了默认的日志格式配置：
C:\Users\Administrator.m2\repository\org\springframework\boot\spring-boot\2.2.2.RELEASE\spring-boot-2.2.2.RELEASE.jar!\org\springframework\boot\logging\logback\defaults.xml
<?xml version="1.0" encoding="UTF-8"?>
<!--
Default logback configuration provided for import
-->
<included>
<conversionRule conversionWord="clr" converterClass="org.springframework.boot.logging.logback.ColorConverter" />
<conversionRule conversionWord="wex" converterClass="org.springframework.boot.logging.logback.WhitespaceThrowableProxyConverter" />
<conversionRule conversionWord="wEx" converterClass="org.springframework.boot.logging.logback.ExtendedWhitespaceThrowableProxyConverter" />
<property name="CONSOLE_LOG_PATTERN" value="${CONSOLE_LOG_PATTERN:-%clr(%d{${LOG_DATEFORMAT_PATTERN:-yyyy-MM-dd HH:mm:ss.SSS}}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}"/>
<property name="FILE_LOG_PATTERN" value="${FILE_LOG_PATTERN:-%d{${LOG_DATEFORMAT_PATTERN:-yyyy-MM-dd HH:mm:ss.SSS}} ${LOG_LEVEL_PATTERN:-%5p} ${PID:- } --- [%t] %-40.40logger{39} : %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}"/>
<logger name="org.apache.catalina.startup.DigesterFactory" level="ERROR"/>
<logger name="org.apache.catalina.util.LifecycleBase" level="ERROR"/>
<logger name="org.apache.coyote.http11.Http11NioProtocol" level="WARN"/>
<logger name="org.apache.sshd.common.util.SecurityUtils" level="WARN"/>
<logger name="org.apache.tomcat.util.net.NioSelectorPool" level="WARN"/>
<logger name="org.eclipse.jetty.util.component.AbstractLifeCycle" level="ERROR"/>
<logger name="org.hibernate.validator.internal.util.Version" level="WARN"/>
</included>
如果想要自定义日志文件配置：
如果类路径下有如下文件，springboot将会自动加载覆盖默认配置:
logback-spring.xml
logback.xml
logback-spring.groovy
logback.groovy
spring推荐使用-spring的写法。这样可以使用springboot提供的profile功能。（不加的话会被日志框架识别从而绕过springboot，这样就不能使用这个功能。）
<springProfile name="staging">
<!-- configuration to be enabled when the "staging" profile is active -->
</springProfile>
<springProfile name="dev | staging">
<!-- configuration to be enabled when the "dev" or "staging" profiles are active -->
</springProfile>
<springProfile name="!production">
<!-- configuration to be enabled when the "production" profile is not active -->
</springProfile>
示例
配置文件
D:\springbootdemo\src\main\resources\logback-spring.xml
<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false" scan="true" scanPeriod="60 seconds">

</encoder>
</appender>
<!--输出到文件-->
<!-- RollingFileAppender：滚动记录文件，先将日志记录到指定文件，当符合某个条件时，将日志记录到其他文件 -->
<!-- 以下的大概意思是：1.先按日期存日志，日期变了，将前一天的日志文件名重命名为XXX%日期%索引，新的日志仍然是sys.log -->
<!-- 2.如果日期没有发生变化，但是当前日志的文件大小超过1KB时，对当前日志进行分割 重命名-->
