org.hibernate.validator.cdi.ValidationExtension

All Implemented Interfaces:

javax.enterprise.inject.spi.Extension

Direct Known Subclasses:

ValidationExtension

public class ValidationExtension
extends java.lang.Object
implements javax.enterprise.inject.spi.Extension

A CDI portable extension which integrates Bean Validation with CDI. It registers the following objects:

• Beans for ValidatorFactory and Validator representing default validator factory and validator as configured via META-INF/validation.xml. These beans will have the Default qualifier and in addition the HibernateValidator qualifier if Hibernate Validator is the default validation provider.
• In case Hibernate Validator is not the default provider, another pair of beans will be registered in addition which are qualified with the HibernateValidator qualifier.

Neither of these beans will be registered in case there is already another bean with the same type and qualifier(s), e.g. registered by another portable extension or the application itself.
