I am trying to use bean validation (using Hibernate implementation) in an OSGI context.
The setup is the following in my blueprint file:
<jaxrs:server address="/myPath" id="myserverid">
<jaxrs:serviceBeans>
<ref component-id="myRestImpl"/>
</jaxrs:serviceBeans>
<jaxrs:providers>
</jaxrs:providers>
<jaxrs:inInterceptors>
<ref component-id="validationInInterceptor" />
</jaxrs:inInterceptors>
</jaxrs:server>
<bean id="validationInInterceptor" class="org.apache.cxf.jaxrs.validation.JAXRSBeanValidationInInterceptor">
<property name="provider" ref="validationProvider" />
</bean>
<bean id="validationProvider" class="org.apache.cxf.validation.BeanValidationProvider"/>
This way I am getting the following error in Karaf:
Status: Failure

Exception:

It is known that the BeanValidationProvider is not very OSGI friendly so I am trying to bootstrap a provider directly in my blueprint.
I know I can get a factory doing the following:
Configuration<?> configuration = Validation.byDefaultProvider().providerResolver(
new HibernateValidationProviderResolver()
).configure();
ValidatorFactory instance = configuration.buildValidatorFactory();
The Custom ValidationProviderResolver:
public class HibernateValidationProviderResolver implements ValidationProviderResolver {
@Override
public List getValidationProviders() {
List providers = new ArrayList(1);
providers.add(new HibernateValidator());
return providers;
}
}
This way I can get a both a validator and a factory but I am unable to inject it somehow in the InInterceptor like its supposed to in an non-OSGi environment.
So I'm basically looking for a workaround here!
See this link for the documentation of BeanValidation in CXF.
Just found out a working solution:
My blueprint file:
<jaxrs:server address="/myPath" id="myserverid">
<jaxrs:serviceBeans>
<ref component-id="myRestImpl"/>
</jaxrs:serviceBeans>
<jaxrs:providers>
</jaxrs:providers>
<jaxrs:inInterceptors>
<ref component-id="validationInInterceptor" />
</jaxrs:inInterceptors>
</jaxrs:server>
<bean id="validationInInterceptor" class="org.apache.cxf.jaxrs.validation.JAXRSBeanValidationInInterceptor">
<property name="provider" ref="validationProvider" />
</bean>
<bean id="validationProvider" class="foo.bar.mycompany.CustomBeanValidationProvider"/>
My CustomBeanValidationProvider:
public class CustomBeanValidationProvider extends BeanValidationProvider {
public CustomBeanValidationProvider() {
super(new HibernateValidationProviderResolver());
}
}
And the custom ValidationProviderResolver I'm using:
public class HibernateValidationProviderResolver implements ValidationProviderResolver {
@Override
public List getValidationProviders() {
List providers = new ArrayList(1);
providers.add(new HibernateValidator());
return providers;
}
}
Hope It will help someone !
