Understanding Bean Validation and Spring Validation in Java Applications

Bean Validation (JSR‑303/380) offers a standard, annotation‑driven API—implemented by Hibernate Validator—for declaring constraints such as @NotNull or @Email, while Spring integrates it via @Valid and @Validated (with group support and AOP‑based method validation), enabling automatic request‑body checks, custom constraints, and service‑layer validation, provided the proper annotations are applied.
