Spring Boot

Understand the idea

Boot combines dependency management, starters, auto-configuration, and an application launcher. An embedded server lets a Java main method start the web application. Boot configures infrastructure according to dependencies, properties, and existing beans; you still implement the domain behavior.

A concrete example

SpringApplication.run(TodoApplication.class, args);

mvn spring-boot:run

In the application

TodoApplication starts each lab. pom.xml selects the starters, while application.properties selects the port and database configuration.

Auto-configuration does not implement CRUD, ownership checks, or login business rules for you.
