錯誤：java.lang.ClassCastException：類org.apache.cxf.bus.spring.SpringBusFactory

直升機！錯誤：java.lang.ClassCastException：類org.apache.cxf.bus.spring.SpringBusFactory

我試圖創建一個使用CXF Web服務客戶端。我的應用程序在OSGi中。我使用Felix框架。

但出現以下錯誤：

我說，這可能是因爲不同的ClassLoader。可能嗎？

任何想法如何解決這個問題？

謝謝！

是的，它看起來就像你有兩個BusFactory類定義。 SpringBusFactory實現其中的一個，而asSubclass（）調用則在另一個上進行。由於一個BusFactory與另一個BusFactory不同，你會得到一個CCE。查找包含BusFactory類的兩個不同的包。其中一個將由定義SpringBusFactory的包導入。

Felix中沒有兩個類BusFactory的實現。只有cxf-bundle。而我的bundle不導入類SpringBusFactory，只有javax.xml.ws.Service類。 – user923957

我認爲「兩所BusFactory類定義」是一個紅色的鯡魚。

不確定您使用的CXF版本是什麼（猜測2.4.2），但該代碼在尋找子類實現時嘗試使用線程上下文類加載器來執行ServiceLoader類。

我最好的猜測是有一些春「神奇」的是CXF依賴於你的缺失，提供它的包。查看Karaf的CXF功能，它具有大量的依賴關係，請檢查並確保您已獲得全部 - 此時使用安裝了CXF功能的karaf可以更容易地嘗試此操作。

如果你正在使用Maven的特徵文件可以用此來訪問：

<dependency> 
     <groupId>org.apache.cxf.karaf</groupId> 
     <artifactId>apache-cxf</artifactId> 
     <version>2.4.2</version> 
     <type>xml</type> 
     <classifier>features</classifier> 
    </dependency>

我發現SOAP客戶端在OSGi環境中不適用於CXF。 – user923957

Hi @ user923957你能解決這個問題嗎？ – udi

我已經看到了奇怪的錯誤，如與在PAX-考試過去。這是否在「正常」OSGi環境下的pax考試之外運行？ Talend Service Factory（http://talend.com/products/tsf）有幾個CXF客戶端和服務在OSGi中運行的示例（在單獨的示例下載包中），它們都可以工作。
