Spring Boot is a framework built on top of the Spring Framework, designed to simplify the process of building stand-alone, production-ready Spring applications.
What is Spring Boot?
- Spring Boot is a project under the Spring ecosystem that simplifies application configuration and development.
- It eliminates boilerplate configurations by using defaults and annotations.
- It includes an embedded server (e.g., Tomcat, Jetty) for running applications without external setup.
Why Use Spring Boot?
- Provides auto-configuration for Spring applications, reducing manual setup.
- Simplifies the creation of REST APIs and microservices.
- Offers a built-in embedded server, eliminating the need for external deployment.
- Reduces boilerplate code with features like Spring Initializer for project scaffolding.
- Makes testing easier with built-in tools and test libraries.
Prerequisites to Learn Spring Boot
- Strong understanding of Core Java and object-oriented programming.
- Familiarity with Spring Framework basics like dependency injection and Spring MVC.
- Basic knowledge of web technologies like HTTP, REST, and JSON.
Scope of Spring Boot
- Powers microservices architecture for cloud-native applications.
- Used in building scalable, high-performance enterprise systems.
- Plays a crucial role in modern DevOps workflows with containerization tools like Docker and Kubernetes.
