Bean Validation in Spring Boot enforces data integrity across DTOs, controllers, and services by providing reusable constraints, cross-field checks, and custom validators with internationalized messages.
Annotate your DTO fields with the appropriate Jakarta Validation annotations to enforce rules on incoming requests.

Annotate your DTO fields with Jakarta Validation constraints like NotNull or Size to enforce data validation rules on incoming request bodies and domain models in Spring Boot.
Use validation groups to separate create vs update scenarios in Spring Boot, allowing you to apply different constraint sets to the same DTO fields depending on the API operation.
Yes, you can enforce cross-field validation by creating custom constraint annotations and custom validators that implement your specific business rules across multiple DTO fields.
Spring Boot bean validation supports nested objects and collections by applying the @Valid annotation to complex fields, ensuring deep validation of container elements and child models.
Internationalize bean validation error messages by defining custom message sources in Spring Boot, formatting errors into standard RFC 7807 patterns for consistent API responses.
Jakarta Validation enforces method-level constraints on service layer parameters and return values in Spring Boot, preventing invalid data from propagating past your controllers into business logic.
