If an entry is found, the content in the cache is immediately returned to the caller, and the method is not invoked. Otherwise, the method is invoked, and the cache is updated before returning the value. ...

When you upgrade Spring Boot itself, these dependencies are upgraded as well in a consistent way. Each release of Spring Boot is associated with a base version of the Spring Framework. Starters are a set of convenient dependency descriptors that you can include in your application. ...
Spring Boot helps you to create stand-alone, production-grade Spring-based applications that you can run. Most Spring Boot applications need very little Spring configuration.
