Spring Boot is a micro-framework open-source maintained by a firm called Pivotal. It provides a platform for Java developers to get started with an auto-configurable spring application in production-grade. With this, developers can easily get started without spending time planning and configuring their spring program. Spring Boot is installed at the top of the spring and includes all the spring features. And is becoming a developer’s favorite these days because it’s a simple production-ready environment that allows developers to concentrate directly on the logic instead of dealing with the configuration and setup. Spring Boot architecture: Since Spring boot uses all spring-like Spring Files, Spring MVC, etc. features/modules, so the architecture is almost the same as spring MVC, except for the fact that there is no need for DAO and DAOImpl classes in spring boot. Instead of creating a data access layer, only a repository class is required which implements class-containing CRUD operation. A customer demands the https (PUT / GET) Then, as the request handles it, it goes to the controller, and the controller mapped with that path and calls the service logic if necessary. Business logic is performed in the service layer which may be performing model/entity class logic on data from the database mapped through JPA. Finally, if no error occurred, a JSP page is returned in the answer. Features of Spring Boot: It provides a flexible way to configure Java Beans, XML configurations, and Database Transactions. It provides a powerful batch processing and manages REST endpoints. In Spring Boot, everything is auto-configured; no manual configurations are needed. It offers annotation-based spring application Eases dependency management It includes Embedded Servlet Container Goals of Spring Boot To avoid complex XML configuration in spring To develop production-ready spring applications in an easier way To reduce the development time and run the application independently Offer an easier way of getting started with the application Advantages of Spring Boot Easy to understand and develop spring application Increases productivity Reduces the development time
