logback配置文件拆分，抽取公共配置

完整的日志文件 https://www.cnblogs.com/gyjx2016/p/5900035.html

日志拆分的原因：

1、抽取公共部分统一管理

2、统一日志格式

3、方便维护

1、新建base-logback.xml

<!--定义公共配置-->
<included>
    <!--日志公共配置-->
    <!--日志格式-->
    <property name="PATTERN" value="%d{yyyy-MM-dd HH:mm:ss.SSS} %X{TRACE_ID} [%thread] %-5level %logger[%L] - %m%n"/>
    <!--日志编码-->
    <property name="CHARSET" value="utf-8"/>
    <!--单个日志文件大小-->
    <property name="MAX_FILE_SIZE" value="10Kb"/>
    <!--日志过期时间-->
    <property name="MAX_HISTORY" value="1"/>
    <!--日志根路径-->
    <property name="BASE_LOG_PATH" value="/data/logs"/>

    <!--控制台打印日志-->
    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>${PATTERN}</pattern>
            <charset>${CHARSET}</charset>
        </encoder>
    </appender>


    <appender name="fileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <!--当前日志文件名-->
        <File>${BASE_LOG_PATH}/${SERVICE_NAME}/${SERVICE_NAME}-info.log</File>
        <!--日志级别过滤-->
        <filter class="com.luna.log.filter.LogbackInfoAndDebugFilter"></filter>
        <!--日志滚动策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--日志归档文件名-->
            <fileNamePattern>${BASE_LOG_PATH}/${SERVICE_NAME}/${SERVICE_NAME}-info.log.%d{yyyy-MM-dd}.log.%i.gz
            </fileNamePattern>
            <!--按天滚动-->
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <!--单个日志文件最大，也会滚动-->
                <maxFileSize>${MAX_FILE_SIZE}</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
            <!--日志存活时间，大于这个时间的日志都将会删除-->
            <maxHistory>${MAX_HISTORY}</maxHistory>
        </rollingPolicy>
        <encoder>
            <!--日志格式-->
            <pattern>${PATTERN}</pattern>
            <!--日志编码-->
            <charset>${CHARSET}</charset>
        </encoder>
    </appender>


    <appender name="errorAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>${BASE_LOG_PATH}/${SERVICE_NAME}/${SERVICE_NAME}-error.log</File>
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${BASE_LOG_PATH}/${SERVICE_NAME}/${SERVICE_NAME}-error.log.%d{yyyy-MM-dd}.log.%i.gz
            </fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>${MAX_FILE_SIZE}</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
            <maxHistory>${MAX_HISTORY}</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>${PATTERN}</pattern>
            <charset>${CHARSET}</charset>
        </encoder>
    </appender>


    <!--开启logback异步记录日志-->
    <appender name="async-console" class="ch.qos.logback.classic.AsyncAppender">
        <appender-ref ref="console"/>
        <includeCallerData>true</includeCallerData>
    </appender>

    <appender name="async-fileAppender" class="ch.qos.logback.classic.AsyncAppender">
        <appender-ref ref="fileAppender"/>
        <includeCallerData>true</includeCallerData>
    </appender>

    <appender name="async-errorAppender" class="ch.qos.logback.classic.AsyncAppender">
        <appender-ref ref="errorAppender"/>
        <includeCallerData>true</includeCallerData>
    </appender>


    <!--整个项目打印INFO 以上级别-->
    <logger name="com.luna" level="INFO">
        <appender-ref ref="async-fileAppender"/>
        <appender-ref ref="async-errorAppender"/>
    </logger>

    <!--记录druid-sql的记录-->
    <logger name="druid.sql.Statement" level="debug" additivity="false">
        <appender-ref ref="async-console"/>
        <appender-ref ref="async-fileAppender"/>
    </logger>
</included>

2、新建logback-spring.xml引用base-logback.xml

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

    <!--日志服务名-->
    <property scope="local" name="SERVICE_NAME" value="demo"/>

    <!--引用公共日志-->
    <include resource="base-logback.xml"/>

    <!--全局打印INFO 级别日志-->
    <root level="INFO">
        <appender-ref ref="async-console"/>
    </root>

</configuration>

因为我的项目是springboot构建，所以命名logback-spring.xml，这种命名可以使用spring标签
