springboot+logback日志时间切割

1.jar

一定不要引入多于的log相关的jar，官网自带的默认就是logback

2.logback.xml

新建logback.xml放入resource目录下

<?xml version="1.0" encoding="UTF-8"?>
<!-- Logback configuration. See http://logback.qos.ch/manual/index.html -->
<configuration scan="true" scanPeriod="10 seconds">
    <include resource="org/springframework/boot/logging/logback/base.xml" />

    <!--日志输出路径-->
    <property name="LOG_PATH" value="/app/mdr/logs" />
    <!--项目名-->
    <property name="APP_NAME" value="mdr" />

    <appender name="INFO_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>${LOG_PATH}/${APP_NAME}_info.log</File>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_PATH}/info-%d{yyyyMMdd}.log.%i</fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>500MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
            <maxHistory>30</maxHistory>
        </rollingPolicy>
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n
            </Pattern>
        </layout>
    </appender>

    <appender name="ERROR_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
        <File>${LOG_PATH}/${APP_NAME}_error.log</File>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_PATH}/error-%d{yyyyMMdd}.log.%i
            </fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>500MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
            <maxHistory>30</maxHistory>
        </rollingPolicy>
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n
            </Pattern>
        </layout>
    </appender>

    <root level="INFO">
        <appender-ref ref="INFO_FILE" />
        <appender-ref ref="ERROR_FILE" />
    </root>

    <logger name="org.springframework.boot" level="INFO"/>

</configuration>

3.application.properties

可以什么都不用配置，如果需要的话，配上sql的打印日志
logging.level.com...dao=debug

备选配置文件

<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>
    <include resource="org/springframework/boot/logging/logback/console-appender.xml"/>
    <property name="FILE_LOG_PATTERN" value="%d{yyyy-MM-dd HH:mm:ss} %highlight(%-5level) %(%thread) %(%logger) %line{1} %msg%n" />
    <!--应用名称-->
    <property name="APP_NAME" value="partyplus"/>
    <!--日志文件保存路径-->
    <property name="LOG_FILE_PATH" value="${LOG_PATH:-.}"/>
    <contextName>${APP_NAME}</contextName>

    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>${FILE_LOG_PATTERN}</pattern>
            <charset>UTF-8</charset>
        </encoder>
    </appender>

    <!--每天记录日志到文件appender-->
    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>${LOG_FILE_PATH}/${APP_NAME}.log</File>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

        </encoder>
    </appender>
    
    <!--myibatis log configure-->
    <logger name="com.apache.ibatis" level="INFO"/>
    <logger name="java.sql.Connection" level="INFO"/>
