springboot-用logback将日志文件按等级保存到不同文件

springboot-用logback将日志文件按等级保存到不同文件

案例：

例如项目基本包名为com.xxx，将该包下的所有日志按debug、info、warn、error等级分别保存到D:/log文件夹下的logback_debug、logback_info、logback_warn、

logback_error文件中。每日凌晨0点将日志文件归档保存为zip压缩包，每个压缩包最大50M,若压缩包文件大小超过50M，将会被保存为多个压缩包。最多保留最近

30天的归档日志文件。

logback-spring.xml配置文件如下图所示：

<configuration debug="false" scan="true" scanPeriod="10 seconds">
<!--<include resource="org/springframework/boot/logging/logback/base.xml"/>-->
<!--<include resource="org/springframework/boot/logging/logback/console-appender.xml"/>-->

<contextName>logback</contextName>

<!--输出sql语句-->
<logger name="com.xxx" level="debug"/>
<property name="path" value="D:/log"></property>
<property name="maxHistory" value="30"/>
<property name="maxFileSize" value="50MB"/>
