What are Spring Boot validation annotations?
An example of an AI chatbot conversation about Spring Boot validation annotations.
What are Spring Boot validation annotations?
Spring Boot validation annotations are used to enforce constraints on Java objects, ensuring data integrity.
Can you give me some examples of these annotations?
Sure! Common annotations include @NotNull, @Size, @Min, and @Max, which validate fields in your models.
How do I use these annotations in my Spring Boot application?
You can use them by adding the annotations directly to your model class fields and then validating them in your controller.
What happens if validation fails?
If validation fails, Spring Boot will throw a MethodArgumentNotValidException, and you can handle it to return appropriate error messages.
