CDI：從掃描中排除類的註釋

我有一個只能有選擇地動態加載的類，當有其他依賴項可用時。CDI：從掃描中排除類的註釋

但CDI（焊接）掃描它並報告一個醜陋的錯誤，見下文。

如何擺脫它，理想情況下使用一些註釋？

沒有註釋做開箱即用，但是Apache Deltaspike和其他幾個人提供@Veto。

不是添加依賴你可能只是做一個簡單的CDI擴展，將否決你的類型，像這樣：

public class VetoExtension implements Extension { 

    public void vetoMyType(@Observes ProcessAnnotatedType<YourTypeGoesHere> pat) { 
     pat.veto(); 
    } 

}

你可以看到這個更多的進入和一個具體的例子：CDI Portable Extensions

根據@ LightGuard的以下評論，在CDI 1.1中，這將與@Vetoed

開箱即用。右，我看着@Vetoed，但我的應用程序沒有與Weld 2.x一起工作，也許我會看看進入它，修復並使用它。 –
