Answer
@Valid triggers validation of the request body against defined constraints.
By placing @Valid on a method parameter in a Spring Boot controller, you activate the validation mechanism. This ensures that any constraint violations are caught immediately, and an appropriate error response is returned. For instance, if a user registration form contains an email field annotated with @Email, the @Valid annotation will cause the API to reject any requests with an invalid email format.
