1、创建文件
在项目的resources目录下，创建logback-spring.xml文件
2、基本格式
logback-spring.xml文件的最外层标签为
<configuration scan="true" scanPeriod="60 seconds" debug="false">....<conversionRule /><property /><appender />.......</configuration>3、引入色彩依赖
<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"/>4、设置属性参数
<property resource="application.yml"/> <property name="log.path" value="logs"/> <property name="log.pattern"value="%clr(%d{${yyyy-MM-dd HH:mm:ss.SSS}}){faint} {magenta} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%20.20t]){faint} %clr(%-40.40logger{39}){cyan} : %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}"/> <property name="file.log.pattern"value="%d{${yyyy-MM-dd HH:mm:ss.SSS}} ${LOG_LEVEL_PATTERN:-%5p} ${PID:- } --- [%15.15t] %-40.40logger{39} : %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}"/>5、控制台输出appender
配置控制台输出的appender
<appender name="console" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>${log.pattern}</pattern> <charset>UTF-8</charset> </encoder> </appender>6、Info类型日志文件储存
通过RollingFileAppender实现，输出到硬盘的文件进行动态滚动，通过LevelFilter过虑其他类型的日志，保证INFO级别日志才能写道文件中；
<appender name="file_info" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${log.path}/info.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"> <fileNamePattern>${log.path}/info/%d{yyyy-MM-dd}-%i.log</fileNamePattern> <maxFileSize>10MB</maxFileSize> <maxHistory>15</maxHistory> <totalSizeCap>20GB</totalSizeCap> </rollingPolicy> <encoder> <pattern>${file.log.pattern}</pattern> <charset>UTF-8</charset> </encoder> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>INFO</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender>7、error类型日志文件储存
通过RollingFileAppender实现，输出到硬盘的文件进行动态滚动，通过LevelFilter过虑其他类型的日志，保证ERROR级别日志才能写道文件中；
<appender name="file_error" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${log.path}/error.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"> <fileNamePattern>${log.path}/error/%d{yyyy-MM-dd}-%i.log</fileNamePattern> <maxFileSize>10MB</maxFileSize> <maxHistory>15</maxHistory> <totalSizeCap>20GB</totalSizeCap> </rollingPolicy> <encoder> <pattern>${file.log.pattern}</pattern> <charset>UTF-8</charset> </encoder> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender>7、全局日志文件储存
可以为error、info级别的日志单独配置不同的文件进行储存，但是在查看实时日志时不直观，因为不能同时查看error、info、debug等级别的日志，为了解决这个问题，引入一个全局日志文件来记录所有级别的日志，并且不做任何的储存，用于排查问题时，进行实时的显示。文件只会有一个，并且大小不超过5MB，记录的是最新的日志信息。
<appender name="file_application" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${log.path}/application.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> <fileNamePattern>${log.path}/application/application.%i.log</fileNamePattern> <minIndex>1</minIndex> <maxIndex>1</maxIndex> </rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <maxFileSize>5MB</maxFileSize> </triggeringPolicy> <encoder> <pattern>${file.log.pattern}</pattern> <charset>UTF-8</charset> </encoder> </appender>8、配置logger
