Study Notes
Spring Boot Fundamentals
Spring Boot is a popular framework known for its simplified approach to building APIs and web services. Developed to make the process of setting up a full web project easy, it includes a fully functioning embedded servlet container, and is built on top of the Spring Framework. Spring Boot provides extensive support for building RESTful web services, making it a preferred choice for developers seeking to create APIs.
Spring Boot Controllers
Controllers are crucial components in Spring Boot. They handle incoming HTTP requests and generate appropriate responses. Using Spring Boot's @RestController annotation, developers can easily create RESTful controllers for handling different types of requests. These controllers can be decorated with additional annotations like @GetMapping, @PostMapping, etc., to specify the desired HTTP methods.
RESTful Web Services Principles
RESTful web services adhere to several guiding principles:
- Resource Identification through URI: Each resource has an individual and globally unique identifier in the form of a Uniform Resource Identifier (URI).
- Uniform Interface: Resources are subjected to a consistent set of operations: PUT, GET, POST, and DELETE, denoted by respective HTTP methods.
- Stateless Interaction: All information needed to service any request is contained within the client itself.
- Client-Server Architecture: Clients initiate the interaction by sending a request to the server.
- Cache Mechanisms: Responses must indicate whether they are cacheable.
- Layered System: Clients can access resources through a hierarchical architecture of layers.
These principles enable RESTful services to provide fast, lightweight, and secure communication between clients and servers.
