org.springframework.validation.beanvalidation.LocalValidatorFactoryBean

All Implemented Interfaces:

OptionalValidatorFactoryBean

public class LocalValidatorFactoryBean
extends SpringValidatorAdapter
implements ValidatorFactory, ApplicationContextAware, InitializingBean, DisposableBean

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!

As of Spring 4.0, this class supports Bean Validation 1.0 and 1.1, with special support for Hibernate Validator 4.3 and 5.x (see setValidationMessageSource(org.springframework.context.MessageSource)).

Note that Bean Validation 1.1's #forExecutables method isn't supported: We do not expect that method to be called by application code; consider MethodValidationInterceptor instead. If you really need programmatic #forExecutables access, inject this class as a ValidatorFactory and call getValidator() on it, then #forExecutables on the returned native Validator reference instead of directly on this class. Alternatively, call #unwrap(Validator.class) which will also provide the native object.

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

Since:

3.0

Method Detail

setProviderClass

public void setProviderClass(java.lang.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()

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.

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 a DefaultParameterNameDiscoverer.

setMappingLocations

public void setMappingLocations(Resource... mappingLocations)

Specify resource locations to load XML constraint mapping files from, if any.

setValidationProperties

public void setValidationProperties(java.util.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(java.util.Map<java.lang.String,java.lang.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 java.util.Map<java.lang.String,java.lang.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

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

postProcessConfiguration

protected void postProcessConfiguration(Configuration<?> configuration)
