使用 Hibernate 实现在 OSGI 上下文中使用 CXF 进行 Bean 验证

Bean Validation with CXF in OSGI context using Hibernate Implementation

我正在尝试在 OSGI 上下文中使用 bean 验证(使用 Hibernate 实现)。

我的蓝图文件中的设置如下:

 <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"/>

这样我在 Karaf 中得到以下错误:

众所周知,BeanValidationProvider 对 OSGI 不是很友好,所以我试图 bootstrap 直接在我的蓝图中提供一个提供程序。

我知道我可以让工厂做以下事情:

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

自定义 ValidationProviderResolver:

public class HibernateValidationProviderResolver implements ValidationProviderResolver {  

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

这样我可以获得验证器和工厂,但我无法像在非 OSGi 环境中那样以某种方式将其注入 InInterceptor。

所以我基本上是在这里寻找解决方法!

有关 CXF 中 BeanValidation 的文档,请参阅 this link。

刚找到可行的解决方案:

我的蓝图文件:

<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"/>

我的 CustomBeanValidationProvider:

public class CustomBeanValidationProvider extends BeanValidationProvider {

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

我正在使用的自定义 ValidationProviderResolver:

public class HibernateValidationProviderResolver implements ValidationProviderResolver {  

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

希望对大家有所帮助!
