In src/main/resources folder, create logback.xml file. Put these configuration:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
<configuration>
    <!-- File appender -->
     <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>D:\mmt-ws-logs\mmt-ws-log.log</File>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
               <FileNamePattern>D:\mmt-ws-logs\mmt-ws-log.%d{yyyy-MM-dd}.log</FileNamePattern>
               <MaxHistory>30</MaxHistory>
          </rollingPolicy>
   
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <pattern>%d{ISO8601} [%-5p] [%t] %c %X - %m%n</pattern>
        </encoder>
    </appender>
   
    <!-- Console appender -->
      <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <charset>UTF-8</charset>
            <pattern>%d{HH:mm:ss} %level [%thread] %logger [%file:%line] %msg%n</pattern>
        </encoder>
    </appender>

  <root level="INFO,ERROR">
    <appender-ref ref="FILE" />
    <appender-ref ref="STDOUT" />
  </root>
</configuration>

In this case, we use RollingFileAppender to write log to file. It also recreate new file for new date.

For showing in Console, use ConsoleAppender.
