org.springframework.validation.beanvalidation

## Class LocalValidatorFactoryBean

- java.lang.Object
- - org.springframework.validation.beanvalidation.SpringValidatorAdapter
  - - org.springframework.validation.beanvalidation.LocalValidatorFactoryBean

- All Implemented Interfaces:
    Validator, ValidatorFactory, Aware, InitializingBean, ApplicationContextAware, SmartValidator

      public class LocalValidatorFactoryBean
      extends SpringValidatorAdapter
      implements ValidatorFactory, ApplicationContextAware, InitializingBean

  This is the central class for `javax.validation` (JSR-303) setup in a Spring application context: It bootstraps a `javax.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`!

    - #### 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.

        `Validation.byProvider(Class)`, `Validation.byDefaultProvider()`

    - #### 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 4.1 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 `MessageSourceResourceBundleLocator` when constructing your interpolator.

        `ResourceBundleMessageInterpolator`, `MessageSourceResourceBundleLocator`

    - #### 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.

    - #### 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:
        `Configuration.addProperty(String, String)`

    - #### setValidationPropertyMap

          public void setValidationPropertyMap(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:
        `Configuration.addProperty(String, String)`

    - #### 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]".

    - #### 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:
        `BeanInitializationException`

    - #### afterPropertiesSet

          public void afterPropertiesSet()

      Description copied from interface: `InitializingBean`
      Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

      This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

      Specified by:
        `afterPropertiesSet` in interface `InitializingBean`
