This lesson explains why Spring Boot was created and what problems it solves for Java web application development. Learners will see how traditional Spring projects often required significant setup, dependency coordination, XML or Java configuration, servlet container management, and repeated infrastructure decisions before useful application code could be written.
The lesson introduces Spring Boot as an opinionated layer on top of the Spring ecosystem that reduces setup work through auto-configuration, starter dependencies, embedded servers, and production-friendly defaults. It also clarifies what Spring Boot does not do: it does not replace Spring, hide Java fundamentals, or eliminate the need to understand configuration and application design.
