public class Validation
extends java.lang.Object
There are three ways to bootstrap it:
ValidatorFactory
.
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();In this case, the default validation provider resolver will be used to locate available providers.
The chosen provider is defined as followed:
ValidationProviderResolver
instance is used.ValidationProviderResolver
. The chosen
ValidationProvider
is then determined in the same way
as in the default bootstrapping case (see above).
Configuration<?> configuration = Validation .byDefaultProvider() .providerResolver( new MyResolverStrategy() ) .configure(); ValidatorFactory factory = configuration.buildValidatorFactory();
Optionally you can choose a custom ValidationProviderResolver
.
ACMEConfiguration configuration = Validation .byProvider(ACMEProvider.class) .providerResolver( new MyResolverStrategy() ) // optionally set the provider resolver .configure(); ValidatorFactory factory = configuration.buildValidatorFactory();
Note:
ValidatorFactory
object built by the bootstrap process should be cached
and shared amongst Validator
consumers.

buildDefaultValidatorFactory()
Builds and returns a
ValidatorFactory instance based on the
default Jakarta Bean Validation provider and following the XML configuration. |

Builds a

static <T extends Configuration<T>,U extends ValidationProvider<T>> |
byProvider(java.lang.Class<U> providerType)
Builds a
Configuration for a particular provider implementation. |
public static ValidatorFactory buildDefaultValidatorFactory()
ValidatorFactory
instance based on the
default Jakarta Bean Validation provider and following the XML configuration.
The provider list is resolved using the default validation provider resolver logic.
The code is semantically equivalent to
Validation.byDefaultProvider().configure().buildValidatorFactory()
.

Configuration
. The provider list is resolved
using the strategy provided to the bootstrap state.
Configuration<?> configuration = Validation .byDefaultProvider() .providerResolver( new MyResolverStrategy() ) .configure(); ValidatorFactory factory = configuration.buildValidatorFactory();The provider can be specified in the XML configuration. If the XML configuration does not exist or if no provider is specified, the first available provider will be returned.

Configuration
for a particular provider implementation.
Optionally overrides the provider resolution strategy used to determine the provider.
Used by applications targeting a specific provider programmatically.
ACMEConfiguration configuration = Validation.byProvider(ACMEProvider.class) .providerResolver( new MyResolverStrategy() ) .configure();, where
ACMEConfiguration
is the
