springboot配置logback日志到文件，按天储存

(1).配置文件增加如下内容：

application.properties

(2).创建\src\main\resources\logback-spring.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>

    <!-- 设置日志文件路径,${log.path}变量的值 -->
    <property name="log.path" value="logs" />

    <!-- 配置日记记录格式 -->
    <springProfile name="staging">
        <appender name="STAGING" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <encoder>
                <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
            </encoder>
            <file>${log.path}/staging.log</file>
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <fileNamePattern>${log.path}/staging.%d{yyyy-MM-dd}.log</fileNamePattern>
                <maxHistory>10</maxHistory>
            </rollingPolicy>
        </appender>
        <root level="INFO">
            <appender-ref ref="STAGING" />
        </root>
    </springProfile>
</configuration>
