Логгирование в разные файлы в Spring Boot

1) отключаем встроенный логгер спринга

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
        <exclusions>
            <exclusion>
                <artifactId>logback-classic</artifactId>
                <groupId>ch.qos.logback</groupId>
            </exclusion>
            <exclusion>
                <artifactId>log4j-over-slf4j</artifactId>
                <groupId>org.slf4j</groupId>
            </exclusion>
        </exclusions>
    </dependency>

2) добавляем в зависимости какой хотим, к примеру Log4j

3) конфигурирем его как уже душе угодно
