public class LocalValidatorFactoryBean extends SpringValidatorAdapter implements ValidatorFactory, ApplicationContextAware, InitializingBean, DisposableBean
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 5.0, this class requires Bean Validation 1.1+, with special support
for Hibernate Validator 5.x (see setValidationMessageSource(org.springframework.context.MessageSource)
).
This class is also runtime-compatible with Bean Validation 2.0 and Hibernate Validator 6.0,
with one special note: If you'd like to call BV 2.0's getClockProvider()
method,
obtain the native ValidatorFactory
through #unwrap(ValidatorFactory.class)
and call the getClockProvider()
method on the returned native reference there.
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.

Allow Map access to the bean validation properties to be passed to the validation provider,
with the option to add or override specific entries.
|
Validator |
getValidator() |
protected void |
postProcessConfiguration(Configuration<?> configuration)
Post-process the given Bean Validation configuration,
adding to or overriding any of its settings.
|
void |
setApplicationContext(ApplicationContext applicationContext)
Set the ApplicationContext that this object runs in.
|
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. |
void |
setConstraintValidatorFactory(ConstraintValidatorFactory constraintValidatorFactory)
Specify a custom ConstraintValidatorFactory to use for this ValidatorFactory.
|
void |
setMappingLocations(Resource... mappingLocations)
Specify resource locations to load XML constraint mapping files from, if any.
|
void |
setMessageInterpolator(MessageInterpolator messageInterpolator)
Specify a custom MessageInterpolator to use for this ValidatorFactory
and its exposed default Validator.
|
void |
setParameterNameDiscoverer(ParameterNameDiscoverer parameterNameDiscoverer)
Set the ParameterNameDiscoverer to use for resolving method and constructor
parameter names if needed for message interpolation.
|
void |
setProviderClass(Class providerClass)
Specify the desired provider class, if any.
|
void |
setTraversableResolver(TraversableResolver traversableResolver)
Specify a custom TraversableResolver to use for this ValidatorFactory
and its exposed default Validator.
|
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.
|
void |
setValidationProperties(Properties jpaProperties)
Specify bean validation properties to be passed to the validation provider.
|
void |
setValidationPropertyMap(Map<String,String> validationProperties)
Specify bean validation properties to be passed to the validation provider as a Map.
|
void |
setValidationProviderResolver(ValidationProviderResolver validationProviderResolver)
Specify a JSR-303
ValidationProviderResolver for bootstrapping the
provider of choice, as an alternative to META-INF driven resolution. |

public void setValidationMessageSource(MessageSource messageSource)
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.
ResourceBundleMessageInterpolator
public void setTraversableResolver(TraversableResolver traversableResolver)
public void setConstraintValidatorFactory(ConstraintValidatorFactory constraintValidatorFactory)
Default is a SpringConstraintValidatorFactory
, delegating to the
containing ApplicationContext for creating autowired ConstraintValidator instances.
public void setParameterNameDiscoverer(ParameterNameDiscoverer parameterNameDiscoverer)
Default is a DefaultParameterNameDiscoverer
.
public void setMappingLocations(Resource... mappingLocations)
public void setValidationProperties(Properties jpaProperties)
Can be populated with a String "value" (parsed via PropertiesEditor) or a "props" element in XML bean definitions.
public void setValidationPropertyMap(@Nullable Map<String,String> validationProperties)
Can be populated with a "map" or "props" element in XML bean definitions.
public Map<String,String> getValidationPropertyMap()
Useful for specifying entries directly, for example via "validationPropertyMap[myKey]".
public void setConfigurationInitializer(Consumer<Configuration<?>> configurationInitializer)
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(javax.validation.Configuration<?>)
template method.
public void setApplicationContext(ApplicationContext applicationContext)
ApplicationContextAware
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.
