Advent of Spring Boot - DAY04 - Forget controller and use Router Function

Описание: Welcome to Day 4 of the Spring Boot Advent of Code series! 🌐 In this episode, we explore an alternative to the traditional @RestController approach by switching to RouterFunction for defining endpoints. Here's what you'll learn:

What RouterFunction and the functional programming style in Spring Boot are all about.
How to rewrite your existing REST endpoints using the RouterFunction API.
Setting up routing with methods like route(), GET(), POST(), and more.
Pros and cons of using RouterFunction compared to @RestController.
By the end of this session, you'll have a new tool in your Spring Boot toolkit, giving you more flexibility and control over your application's routing logic. Let's go functional! 🛠️✨
