LocalValidatorFactoryBean (Spring Framework 5.2.1.RELEASE API)

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

All Implemented Interfaces:

Validator, ValidatorFactory, Aware, DisposableBean, InitializingBean, ApplicationContextAware, SmartValidator

Direct Known Subclasses:

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 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.

Since:

3.0

  - 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()
  - 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.

    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.

  - setTraversableResolver
```
public void setTraversableResolver(TraversableResolver traversableResolver)

  - 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.

```
    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
