springboot 日志按照年月日保存

在resouces添加文件logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml" />
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{35} - %msg %n</pattern>
            <charset>UTF-8</charset>
        </encoder>
    </appender>
    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <!--<file>d:/tmp/logs/stdout.log</file>-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- daily rollover 保存历史记录到这个文件夹一日起为后缀 -->
            <fileNamePattern>d:/appdata/zhima/%d{yyyy,aux}/%d{MM,aux}/%d{dd,aux}/%d{yyyy-MM-dd}.log</fileNamePattern>
            <!-- keep 30 days' worth of history -->
            <maxHistory>30</maxHistory>
        </rollingPolicy>
        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <maxFileSize>10MB</maxFileSize>
        </triggeringPolicy>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{35} - %msg %n</pattern>
            <charset>UTF-8</charset> <!-- 此处设置字符集 -->
        </encoder>
    </appender>
    <root level="INFO">
        <appender-ref ref="CONSOLE"></appender-ref>
        <appender-ref ref="FILE"></appender-ref>
    </root>
</configuration>

fileNamePattern 就是保存路径
