Re-explain

Spring Boot is an opinionated framework that simplifies Spring application development by providing:

Auto-configuration: Automatically configures Spring applications
Starter dependencies: Pre-configured dependency sets
Embedded servers: Tomcat, Jetty, Undertow embedded
Production-ready features: Metrics, health checks, externalized configuration
No XML configuration: Convention over configuration
Standalone applications: JAR files with embedded servers
