本文探讨了Spring Boot的默认Logback配置文件，并指导读者如何自定义日志格式。重点介绍了如何配置不同组件的日志级别和自定义输出模式。

1.默认logback的配置文件

/org/springframework/boot/spring-boot/2.0.5.RELEASE/spring-boot-2.0.5.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>

2.自定义日志格式

logging:
  file:
    name: lab.log
  level:
    com:
      dao: debug
    root: info
  pattern:
    console: "%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%t]){faint} %clr(%-40.40logger{39}){cyan}[line:%line]    %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:%wEx}"
    file: "%d{yyyy-MM-dd HH:mm:ss.SSS} ${LOG_LEVEL_PATTERN:-%5p} ${PID:- } --- [%t] %-40.40logger{39}[line:%line]: %m%n${LOG_EXCEPTION_CONVERSION_WORD:%wEx}"
