Have you heard anything about Spring MVC?

Yes, I am familiar. Spring MVC is a flexible and powerful web framework that is part of the Spring Framework. It is based on the Model-View-Controller (MVC) pattern and is used for developing web applications.

Main components:

• DispatcherServlet: Front controller that handles incoming HTTP requests and delegates them to appropriate handlers (controllers).
• Controller: Processes requests, interacts with the model, and selects a view for rendering.
• Model: Represents application data. It can be a POJO object.
• View: Responsible for rendering the user interface based on data from the model. Various technologies can be used, such as JSP, Thymeleaf, Freemarker.
• ViewResolver: Determines which view should be used for rendering the response.

Key features:

• Flexibility and loose coupling of components.
• Support for various view technologies.
• Easy testing of controllers and other components.
• Integration with other Spring modules (Spring Security, Spring Data, etc.).
• Support for RESTful web services.
• Use of annotations for configuration (@Controller, @RequestMapping, @GetMapping, @PostMapping).

Example of a simple controller:

// Example of a simple controller
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class GreetingController {

    @GetMapping("/greeting") // Handles GET requests to "/greeting"
    public String greeting(String name, Model model) {
        model.addAttribute("name", name); // Add data to model
        return "greeting"; // Return view name
    }
}

Spring MVC provides a clear separation of concerns, simplifying development, testing, and maintenance of web applications.
