public class MethodValidationPostProcessor
extends org.springframework.aop.framework.AbstractAdvisingBeanPostProcessor
implements org.springframework.beans.factory.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 3.1, this functionality requires Hibernate Validator 4.2 or 4.3. In Spring 4.0, this class will autodetect a Bean Validation 1.1 compliant provider (such as Hibernate Validator 5.0) and automatically use the standard method validation support when available.

3.1

Method Detail

setValidatedAnnotationType

public void setValidatedAnnotationType(java.lang.Class<? extends java.lang.annotation.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.
