在karaf，cxf和dosgi中使用hibernate進行Bean驗證

Question

我使用cxf dosgi在Karaf中暴露了jax-rs服務。我正試圖添加一個休眠提供程序的bean驗證。

1. 我安裝的Hibernate驗證功能
2. 我安裝了CXF豆驗證和CXF豆驗證核心功能，雖然我不知道他們是否都是必要的。

3. 我增加了以下意圖啓用休眠提供商：

   @Component(immediate = true, property = "org.apache.cxf.dosgi.IntentName=bean-validation") 
   public class BeanValidationIntent implements Callable<List<Object>> { 
   
   @Override 
   public List<Object> call() throws Exception { 
   
       List<Object> list = new ArrayList<Object>(); 
   
       BeanValidationFeature beanValidationFeature = new BeanValidationFeature(); 
       beanValidationFeature.setProvider(new BeanValidationProvider(new HibernateValidationProviderResolver())); 
   
       list.add(beanValidationFeature); 
   
       return list; 
   } 
   

   }

但我得到的底部例外。我添加了包含缺少類捆（包裝）：

install -s wrap:mvn:com.sun.el/el-ri/1.0 

這仍然沒有解決問題。

我正在使用karaf 4.0.8

如果您有任何想法，請分享！謝謝！！

Answer 1

的EL ExpressionFactory初始化是有點馬車：它使用TCCL而不是使用自己的類加載和我們Karaf功能，因爲它不應該是必要不會導入com.sun.el的。

我們在HV中引入了externalClassLoader（）方法來（除其他外）解決此問題。

看看我們如何做到使用它在我們的OSGi集成測試： https://github.com/hibernate/hibernate-validator/blob/5.4/osgi/integrationtest/src/test/java/org/hibernate/validator/osgi/integrationtest/OsgiIntegrationTest.java#L139

（請注意，在5.4，你還需要providerResolver（）調用 - 這個限制是在即將移除要熬到6.0）
