Проверка компонентов с помощью CXF в контексте OSGI с использованием реализации Hibernate

Я пытаюсь использовать проверку bean (используя реализацию Hibernate) в контексте OSGI.

В моем файле чертежа установка следующая:

 <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"/>

Таким образом, я получаю следующую ошибку в Karaf:

Status: Failure

Известно, что BeanValidationProvider не очень дружелюбен к OSGI, поэтому я пытаюсь загрузить провайдера прямо в свой проект.

Я знаю, что могу заставить фабрику делать следующее:

Configuration<?> configuration = Validation.byDefaultProvider().providerResolver(
        new HibernateValidationProviderResolver()
    ).configure();
ValidatorFactory instance = configuration.buildValidatorFactory();

Пользовательский ValidationProviderResolver:

public class HibernateValidationProviderResolver implements ValidationProviderResolver {  

    @Override  
    public List getValidationProviders() {  
        List providers = new ArrayList(1);  
        providers.add(new HibernateValidator());  
        return providers;  
    }  
}

Таким образом, я могу получить как валидатор, так и фабрику, но я не могу каким-то образом внедрить его в InInterceptor, как это предполагалось в среде, отличной от OSGi.

Так что я в основном ищу обходной путь здесь!

Только что нашел рабочее решение:

Мой файл чертежа:

<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"/>

Мой CustomBeanValidationProvider:

public class CustomBeanValidationProvider extends BeanValidationProvider {

    public CustomBeanValidationProvider() {
            super(new HibernateValidationProviderResolver());
    }
}

И пользовательский ValidationProviderResolver, который я использую:

public class HibernateValidationProviderResolver implements ValidationProviderResolver {  

    @Override  
    public List getValidationProviders() {  
        List providers = new ArrayList(1);  
        providers.add(new HibernateValidator());  
        return providers;  
    }  
}

Надеюсь, это поможет кому-то!
