JSR-303 ConstraintValidatorFactory implementation that delegates to a Spring BeanFactory for creating autowired ConstraintValidator instances.

Note that this class is meant for programmatic use, not for declarative use in a standard validation.xml file. Consider SpringWebConstraintValidatorFactory for declarative use in a web application, e.g. with JAX-RS or JAX-WS.
