How to configure rolling file appender within Spring Boot's application.yml

Question

Is is possible to configure a daily file appender within the application.yml of a Spring Boot application?

i.e. filenamePattern: myfile.%d{yyyy-MM-dd-HH-mm-ss}.log

I have configuration such as the following in my application.yml file.

logging:     file: /mypath/myfile.log     level:      mypackage: INFO 

Thanks

The default file appender is size based (10MB).

In your logback.xml just configure a TimeBasedRollingPolicy as described here

I.e. something like:

<?xml version="1.0" encoding="UTF-8"?> <configuration>   <include resource="org/springframework/boot/logging/logback/base.xml"/>    <appender name="ROLLIN" class="ch.qos.logback.core.rolling.RollingFileAppender">     <file>${LOG_FILE}</file>     <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">          <!-- daily rollover -->         <fileNamePattern>${LOG_FILE}.%d{yyyy-MM-dd}.log</fileNamePattern>      </rollingPolicy>   </appender>    <root level="INFO">     <appender-ref ref="ROLLIN" />   </root>    <logger name="org.springframework.web" level="INFO"/> </configuration>
