What modules and components are included in Spring Boot and how do they interact?

Spring Boot is a framework for simplifying the creation of applications on Spring. Its main modules and components include:

• Spring Boot Starter — a set of dependencies that simplifies the inclusion of necessary libraries (e.g., web, data-jpa, security).
• Auto-Configuration — automatically configures the application based on dependencies and configurations, reducing the need for manual setup.
• Spring Boot Actuator — provides metrics, health checks, and application monitoring.
• Spring Boot CLI — a command-line tool for quickly creating and running applications.
• Spring Boot DevTools — enhances development with automatic restarts and other conveniences.

The interaction works as follows: starters include the necessary libraries, auto-configuration analyzes the classpath and configurations to automatically set up beans and components. Actuator is integrated for monitoring, and DevTools assists during development.
