```
public class MethodValidationPostProcessor
extends AbstractBeanFactoryAwareAdvisingPostProcessor
implements InitializingBean
```
A convenient 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 5.0, this functionality requires a Bean Validation 1.1+ provider.

public MethodValidationPostProcessor()

- Method Detail
  - setValidatedAnnotationType
```
public void setValidatedAnnotationType(Class<? extends Annotation> validatedAnnotationType)
```
    Set the 'validated' annotation type. The default validated annotation type is the 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.
    Parameters:
    validatedAnnotationType - the desired annotation type
  - setValidator
```
public void setValidator(Validator validator)
```
    Set the JSR-303 Validator to delegate to for validating methods.
    Default is the default ValidatorFactory's default Validator.
  - setValidatorFactory
```
public void setValidatorFactory(ValidatorFactory validatorFactory)
```
    Set the JSR-303 ValidatorFactory to delegate to for validating methods, using its default Validator.
    Default is the default ValidatorFactory's default Validator.
    See Also:
    ValidatorFactory.getValidator()
  - afterPropertiesSet
```
public void afterPropertiesSet()
```
    Description copied from interface: InitializingBean
    Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.
    This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
    Specified by:
    afterPropertiesSet in interface InitializingBean
  - createMethodValidationAdvice
```
protected Advice createMethodValidationAdvice(@Nullable
                                              Validator validator)
```
    Create AOP advice for method validation purposes, to be applied with a pointcut for the specified 'validated' annotation.
    Parameters:
    validator - the JSR-303 Validator to delegate to
    Returns:
    the interceptor to use (typically, but not necessarily, a MethodValidationInterceptor or subclass thereof)
