Under The Boot – Spring Boot - DZone

Remember the times when we had to register dispatchers, viewResolvers, etc. to make our spring application web app? Then there was @EnableWebMvc annotation, and now even this is redundant. These days the only thing you need to do is to add org.springframework.boot:spring-boot-starter-web dependency to your project and everything else is done automagically. The same goes for a database connection.
