<parent> in pom.xml takes care of dependency management super well and Spring Boot recommend use <parent>.

If want custom own dependency configure without <parent> tag, can use <dependencyManagement> like below coed.

<dependencyManagement>

        <dependency>
            <!-- Import dependency management from Spring Boot -->
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-dependencies</artifactId>
            <version>2.2.4.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

If want add other dependency, just write dependency code in <dependencies> at pom.xml.
