# Package org.springframework.validation.beanvalidation

Support classes for integrating a JSR-303 Bean Validation provider (such as Hibernate Validator 4.0) into a Spring ApplicationContext and in particular with Spring's data binding and validation APIs.

See: Description

- Class Summary
  Class | Description
  --- | ---
  BeanValidationPostProcessor | Simple `BeanPostProcessor` that checks JSR-303 constraint annotations in Spring-managed beans, throwing an initialization exception in case of constraint violations right before calling the bean's init method (if any).
  CustomValidatorBean | Configurable bean class that exposes a specific JSR-303 Validator through its original interface as well as through the Spring `Validator` interface.
  LocaleContextMessageInterpolator | Delegates to a target `MessageInterpolator` implementation but enforces Spring's managed Locale.
  LocalValidatorFactoryBean | This is the central class for `javax.validation` (JSR-303) setup in a Spring application context: It bootstraps a `javax.validation.ValidationFactory` and exposes it through the Spring `Validator` interface as well as through the JSR-303 `Validator` interface and the `ValidatorFactory` interface itself.
  MessageSourceResourceBundleLocator | Implementation of Hibernate Validator 4.1's `ResourceBundleLocator` interface, exposing a Spring `MessageSource` as localized `MessageSourceResourceBundle`.
  MethodValidationInterceptor | An AOP Alliance `MethodInterceptor` implementation that delegates to a JSR-303 provider for performing method-level validation on annotated methods.
  MethodValidationPostProcessor | A convenient `BeanPostProcessor` implementation that delegates to a JSR-303 provider for performing method-level validation on annotated methods.
  SpringConstraintValidatorFactory | JSR-303 `ConstraintValidatorFactory` implementation that delegates to a Spring BeanFactory for creating autowired `ConstraintValidator` instances.
  SpringValidatorAdapter | Adapter that takes a JSR-303 `javax.validator.Validator` and exposes it as a Spring `Validator` while also exposing the original JSR-303 Validator interface itself.

## Package org.springframework.validation.beanvalidation Description

Support classes for integrating a JSR-303 Bean Validation provider (such as Hibernate Validator 4.0) into a Spring ApplicationContext and in particular with Spring's data binding and validation APIs.

The central class is `LocalValidatorFactoryBean` which defines a shared ValidatorFactory/Validator setup for availability to other Spring components.
