public class LocalValidatorFactoryBean extends SpringValidatorAdapter implements ValidatorFactory, ApplicationContextAware, InitializingBean, DisposableBean
This is the central class for jakarta.validation (JSR-303) setup in a Spring application context: It bootstraps a jakarta.validation.ValidationFactory and exposes it through the Spring Validator interface as well as through the JSR-303 Validator interface and the ValidatorFactory interface itself.

When talking to an instance of this bean through the Spring or JSR-303 Validator interfaces, you'll be talking to the default Validator of the underlying ValidatorFactory. This is very convenient in that you don't have to perform yet another call on the factory, assuming that you will almost always use the default Validator anyway. This can also be injected directly into any target dependency of type Validator!

This class is also being used by Spring's MVC configuration namespace, in case of the jakarta.validation API being present but no explicit Validator having been configured.

  • Method Details

    • setProviderClass

      public void setProviderClass(Class providerClass)
      Specify the desired provider class, if any.

      If not specified, JSR-303's default search mechanism will be used.

      See Also:

    • setValidationProviderResolver

      public void setValidationProviderResolver(ValidationProviderResolver validationProviderResolver)
      Specify a JSR-303 ValidationProviderResolver for bootstrapping the provider of choice, as an alternative to META-INF driven resolution.
      Since:
      4.3

    • setMessageInterpolator

      public void setMessageInterpolator(MessageInterpolator messageInterpolator)
      Specify a custom MessageInterpolator to use for this ValidatorFactory and its exposed default Validator.

    • setValidationMessageSource

      public void setValidationMessageSource(MessageSource messageSource)
      Specify a custom Spring MessageSource for resolving validation messages, instead of relying on JSR-303's default "ValidationMessages.properties" bundle in the classpath. This may refer to a Spring context's shared "messageSource" bean, or to some special MessageSource setup for validation purposes only.

      NOTE: This feature requires Hibernate Validator 4.3 or higher on the classpath. You may nevertheless use a different validation provider but Hibernate Validator's ResourceBundleMessageInterpolator class must be accessible during configuration.

      Specify either this property or "messageInterpolator", not both. If you would like to build a custom MessageInterpolator, consider deriving from Hibernate Validator's ResourceBundleMessageInterpolator and passing in a Spring-based ResourceBundleLocator when constructing your interpolator.

      In order for Hibernate's default validation messages to be resolved still, your MessageSource must be configured for optional resolution (usually the default). In particular, the MessageSource instance specified here should not apply "useCodeAsDefaultMessage" behavior. Please double-check your setup accordingly.

      See Also:
      • ResourceBundleMessageInterpolator

    • setTraversableResolver

      public void setTraversableResolver(TraversableResolver traversableResolver)
      Specify a custom TraversableResolver to use for this ValidatorFactory and its exposed default Validator.

    • setConstraintValidatorFactory

      public void setConstraintValidatorFactory(ConstraintValidatorFactory constraintValidatorFactory)
      Specify a custom ConstraintValidatorFactory to use for this ValidatorFactory.

      Default is a SpringConstraintValidatorFactory, delegating to the containing ApplicationContext for creating autowired ConstraintValidator instances.

    • setParameterNameDiscoverer

      public void setParameterNameDiscoverer(ParameterNameDiscoverer parameterNameDiscoverer)
      Set the ParameterNameDiscoverer to use for resolving method and constructor parameter names if needed for message interpolation.

      Default is Hibernate Validator's own internal use of standard Java reflection. This may be overridden with a custom subclass or a Spring-controlled DefaultParameterNameDiscoverer if necessary.

    • setMappingLocations

      public void setMappingLocations(Resource... mappingLocations)
      Specify resource locations to load XML constraint mapping files from, if any.

    • setValidationProperties

      public void setValidationProperties(Properties jpaProperties)
      Specify bean validation properties to be passed to the validation provider.

      Can be populated with a String "value" (parsed via PropertiesEditor) or a "props" element in XML bean definitions.

      See Also:

    • setValidationPropertyMap

      public void setValidationPropertyMap(@Nullable Map<String,String> validationProperties)
      Specify bean validation properties to be passed to the validation provider as a Map.

      Can be populated with a "map" or "props" element in XML bean definitions.

      See Also:

    • getValidationPropertyMap

      public Map<String,String> getValidationPropertyMap()
      Allow Map access to the bean validation properties to be passed to the validation provider, with the option to add or override specific entries.

      Useful for specifying entries directly, for example via "validationPropertyMap[myKey]".

    • setConfigurationInitializer

      public void setConfigurationInitializer(Consumer<Configuration<?>> configurationInitializer)
      Specify a callback for customizing the Bean Validation Configuration instance, as an alternative to overriding the postProcessConfiguration(Configuration) method in custom LocalValidatorFactoryBean subclasses.

      This enables convenient customizations for application purposes. Infrastructure extensions may keep overriding the postProcessConfiguration(jakarta.validation.Configuration<?>) template method.

      Since:
      5.3.19

    • setApplicationContext

      public void setApplicationContext(ApplicationContext applicationContext)
      Description copied from interface: ApplicationContextAware
      Set the ApplicationContext that this object runs in. Normally this call will be used to initialize the object.

      Invoked after population of normal bean properties but before an init callback such as InitializingBean.afterPropertiesSet() or a custom init-method. Invoked after ResourceLoaderAware.setResourceLoader(org.springframework.core.io.ResourceLoader), ApplicationEventPublisherAware.setApplicationEventPublisher(org.springframework.context.ApplicationEventPublisher) and MessageSourceAware, if applicable.

      Specified by:
      setApplicationContext in interface ApplicationContextAware
      Parameters:
      applicationContext - the ApplicationContext object to be used by this object
      See Also:

    • 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

    • postProcessConfiguration

      protected void postProcessConfiguration(Configuration<?> configuration)
      Post-process the given Bean Validation configuration, adding to or overriding any of its settings.

      Invoked right before building the ValidatorFactory.

      Parameters:
      configuration - the Configuration object, pre-populated with settings driven by LocalValidatorFactoryBean's properties
