Spring boot之log4j2按日期拆分日誌

1、application.yml

logging:
  config: classpath:log4j2.xml

2、log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<Configuration monitorInterval="30">
    <Properties>
        <!--系統變量  ${sys:logPath:-/var/logs} 讀取系統變量logPath的值，如果爲空則設默認值：/var/logs-->
       <Property name="LOG_HOME">${sys:catalina.home:-.}/logs</Property>
        <Property name="LOG_BACK_HOME">${sys:catalina.home:-.}/logs/backup</Property>
        <Property name="LOG_PATTERN_LAYOUT">%date %highlight{[%-5.5level]}{STYLE=Logback} [%-10.10thread] [%X{employeeCode}] [%X{X-B3-TraceId}/%X{X-B3-SpanId}] %cyan{[%-50.50class:%-4.4line]} - %msg%xEx%n </Property>
        <Property name="DEFAULT_CHARSET">UTF-8</Property>
        <Property name="ERROR_FILE_NAME">error</Property>
        <Property name="INFO_FILE_NAME">info</Property>
    </Properties>

    <Appenders>
        <!-- 配置日常日誌 -->
        <RollingFile name="${INFO_FILE_NAME}" fileName="${LOG_HOME}/${INFO_FILE_NAME}.log" filePattern="${LOG_BACK_HOME}/$${date:yyyy-MM}/${INFO_FILE_NAME}-%d{yyyy-MM-dd}.log.gz" append="true">

                <TimeBasedTriggeringPolicy interval="1" modulate="true" />
            </Policies>
            <Filters>
                <!--級別大於等於WARN的日誌可以寫入-->
                <ThresholdFilter level="WARN" onMatch="ACCEPT" onMismatch="DENY"/>
            </Filters>
        </RollingFile>
    </Appenders>

    <Loggers>
        <Logger name="org.springframework" level="INFO" additivity = "false">
            <AppenderRef ref="${INFO_FILE_NAME}"/>
            <AppenderRef ref="${ERROR_FILE_NAME}"/>
        </Logger>
        <Logger name="com.picc" level="DEBUG" additivity = "false">
            <AppenderRef ref="${INFO_FILE_NAME}"/>
            <AppenderRef ref="${ERROR_FILE_NAME}"/>
        </Logger>
        <Root level="INFO">
            <AppenderRef ref="${INFO_FILE_NAME}"/>
            <AppenderRef ref="${ERROR_FILE_NAME}"/>
        </Root>
    </Loggers>
</Configuration>

3、使用結果展示

cd backup/

會發現按月份備份

 cd 2020-06/

日誌是壓縮的，自行解壓查看即可
