1. What is Spring MVC?
Ans. Spring MVC is a web application framework developed by the Spring Framework team. It is based on the Model-View-Controller architectural pattern and provides a flexible and scalable way to develop web applications in Java.
2. What is a custom Form Validation annotation in Spring MVC?
Ans. A custom Form Validation annotation in Spring MVC is a user-defined annotation that can be used to validate form input data in web applications. By creating custom annotations, developers can define their own validation rules and apply them to form fields or objects.
3. How can I write a custom Form Validation annotation in Spring MVC?
Ans. To write a custom Form Validation annotation in Spring MVC, you need to create a new annotation interface and define the validation rules using the annotation's attributes. You also need to implement a validator class that implements the Spring Validator interface to perform the actual validation logic.
4. What are the benefits of using custom Form Validation annotations in Spring MVC?
Ans. Using custom Form Validation annotations in Spring MVC provides several benefits. It allows developers to define their own validation rules and apply them consistently across the application. It also improves code readability and maintainability by encapsulating the validation logic within annotations. Additionally, custom annotations can be easily reused in different parts of the application.
5. Can I use multiple custom Form Validation annotations on the same field in Spring MVC?
Ans. Yes, you can use multiple custom Form Validation annotations on the same field in Spring MVC. When multiple annotations are applied to a field, each annotation's validation rules are executed in the order they are declared. If any validation rule fails, an appropriate error message is displayed. This allows for more granular and complex validation scenarios to be implemented.
