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!

Since:

3.0

Method Detail

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:

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

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

Specified by:

getValidator in interface ValidatorFactory

usingContext

public ValidatorContext usingContext()

public MessageInterpolator getMessageInterpolator()

Specified by:

getTraversableResolver

public TraversableResolver getTraversableResolver()

Specified by:

getConstraintValidatorFactory

public ConstraintValidatorFactory getConstraintValidatorFactory()
