public class MethodValidationPostProcessor extends AbstractAdvisingBeanPostProcessor implements InitializingBean
BeanPostProcessor implementation that delegates to a
JSR-303 provider for performing method-level validation on annotated methods.
Applicable methods have JSR-303 constraint annotations on their parameters and/or on their return value (in the latter case specified at the method level, typically as inline annotation), e.g.:
public @NotNull Object myValidMethod(@NotNull String arg1, @Max(10) int arg2)
Target classes with such annotated methods need to be annotated with Spring's
Validated annotation at the type level, for their methods to be searched for
inline constraint annotations. Validation groups can be specified through @Validated
as well. By default, JSR-303 will validate against its default group only.
As of Spring 4.0, this functionality requires either a Bean Validation 1.1 provider (such as Hibernate Validator 5.x) or the Bean Validation 1.0 API with Hibernate Validator 4.3. The actual provider will be autodetected and automatically adapted.

public void setValidatedAnnotationType(java.lang.Class<? extends java.lang.annotation.Annotation> validatedAnnotationType)
Validated annotation.
This setter property exists so that developers can provide their own (non-Spring-specific) annotation type to indicate that a class is supposed to be validated in the sense of applying method validation.
