Required Maven Dependencies

The configuration utilizes several classes from the Logback framework:

• ConsoleAppender: ch.qos.logback.core.ConsoleAppender - Outputs logs to the console
• RollingFileAppender: ch.qos.logback.core.rolling.RollingFileAppender - Outputs logs to files with rolling capabilities
• TimeBasedRollingPolicy: ch.qos.logback.core.rolling.TimeBasedRollingPolicy - Handles log file rotation based on time

These classes are part of the logback-core.jar library. In a Spring Boot application, you typically need to add the web starter dependency which includes logging support:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
