A beginner-oriented walkthrough explaining why Spring Boot was created by contrasting it with traditional Spring MVC + JPA configuration. First, a full 7-step manual setup is shown (Maven dependencies, AppConfig, WebMvcConfig, DispatcherServlet registration, JPA entity, controller, Thymeleaf view) to illustrate the verbosity and boilerplate involved. Then the same application is rebuilt with Spring Boot in 5 simpler steps, demonstrating auto-configuration, starter dependencies, and embedded Tomcat. Key benefits covered: simplified pom.xml via spring-boot-starter-* artifacts, automatic bean wiring for DataSource/EntityManagerFactory/TransactionManager, embedded servlet container, and overridable defaults via application.properties.
