springboot自动清理日志

1. logback-spring.xml

在xml中rollingPolicy标签内加入以下：

<maxHistory>2maxHistory>
<cleanHistoryOnStart>truecleanHistoryOnStart>

完整的文件：

<configuration>

    
    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>

    
    <springProperty scope="context" name="LOG_PATH" source="log.path" defaultValue="app-log"/>

    
    
    
    <springProfile name="local">
        <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

            <appender-ref ref="FILE_ALL"/>
        root>

    springProfile>
configuration>

2. logback.xml

我项目里的logback.xml也更改掉：

<configuration  scan="true" scanPeriod="60 seconds" debug="false">
<contextName>logbackcontextName>
<springProperty scope="context" name="logLevel" source="logging.levels"/>
<springProperty scope="context" name="logPath" source="logging.path"/>

<appender name="console" class="ch.qos.logback.core.ConsoleAppender">

<encoder>
<pattern>%d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%npattern>
<charset>UTF-8charset>
encoder>
appender>


<appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>${logPath}logback.%d{yyyy-MM-dd}.logfileNamePattern>
    <maxHistory>2maxHistory>
    <cleanHistoryOnStart>truecleanHistoryOnStart>
rollingPolicy>
<encoder>
<pattern>%d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%npattern>
<charset>UTF-8charset>
encoder>
appender>


<root level="info">
<appender-ref ref="console" />
<appender-ref ref="file" />
root>
configuration>
