Handling HTTP Requests & Responses
Learn to process request parameters, path variables, request bodies, and craft appropriate HTTP responses.
Requests & Responses
When you interact with a web application, your browser sends an HTTP Request to a server. The server then processes it and sends back an HTTP Response.
In Spring Boot, we write code to listen for these requests, extract information, perform actions, and then craft a suitable response.
Getting Query Params: @RequestParam
Sometimes, extra data is sent in the URL after a ?, like /search?keyword=java. These are query parameters.
Spring Boot uses the @RequestParam annotation to easily extract these values into your method parameters.
