SpringBoot配置logback

0. 杂项技巧

我的常用配置:

logging.pattern.console=%clr(%d{yyyy-MM-dd HH:mm:ss.SSS,GMT+8} [%thread] %-5level %logger{72}[%L] - %msg%n)
logging.level.root=warn
logging.level.com.github.yingzhuo.cheliangbao=trace
logging.level.org.springframework=warn
logging.level.org.hibernate=warn

可以指定日志输出的颜色

%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){yellow}

被支持的颜色有:

blue cyan faint green magenta red yellow

1. logback-spring.xml 可以细化配置profile

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">

    <property resource="logback-spring.properties"/>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS,GMT+8} [%thread] %-5level %logger{72}[%L] - %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="DEBUG_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_DIR}/${DEBUG_LOG_FILE_NAME}.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_DIR}/${DEBUG_LOG_FILE_NAME}.%d{yyyy-MM-dd}.log.gz</fileNamePattern>
            <maxHistory>365</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS,GMT+8} [%thread] %-5level %logger{72}[%L] - %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="BUSINESS_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_DIR}/${BUSINESS_LOG_FILE_NAME}.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

            <maxHistory>365</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS,GMT+8}|%level|%logger|%msg%n</pattern>
        </encoder>
    </appender>

</configuration>

2. logback-spring.properties提供变量定义，指定日志文件位置等信息

##
# 日志存放目录
##
LOG_DIR=/tmp/logs/cheliangbao-rest/

##
# 业务日志文件名
##
BUSINESS_LOG_FILE_NAME=business

##
# 调试日志文件名
##
DEBUG_LOG_FILE_NAME=debug
