Spring Framework FAQ: Top Questions

Spring MVC supports form handling by binding HTML forms to model objects using the ModelAttribute annotation and form tags.

📘 Process:

1. Create a form-backing object (POJO).
2. Bind the object with @ModelAttribute.
3. Use form tags in views (like JSP or Thymeleaf).

📥 Example:

@Controller
public class UserController {

  @GetMapping("/register")
  public String showForm(Model model) {
    model.addAttribute("user", new User());
    return "register";
  }

  @PostMapping("/register")
  public String submitForm(@ModelAttribute("user") User user) {
    // save user
    return "result";
  }
}

🏆 Expected Output:

Form inputs bind to the User object, saved and redirected to result view.

🛠️ Use Cases:

• Binding user input to Java objects.
• Validation and error feedback integration.
