Is the spring version automatically inferred from spring-boot starter parent?
Yes, in a Spring Boot project, the version of the Spring Framework is often inferred from the version of the spring-boot-starter-parent.
By using the spring-boot-starter-parent, you delegate the management of dependencies, including the Spring Framework version, to Spring Boot. The parent POM (Project Object Model) file of the starter contains properties that specify the versions of various libraries, including the Spring Framework.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.0</version>
</parent>
<dependencies>
<!-- Other dependencies specified here will inherit the version from the parent -->
</dependencies>
<build>
<plugins>
<!-- Maven plugins with default configurations -->
</plugins>
</build>
