org.apache.cxf.common.i18n.UncheckedException: No operation was found with the name

前言：

      在一個JavaWeb項目中，要接入WebService時，使用CXF。啓動已經成功，接口也已經成功發佈，但是在調用的時候報出如下異常：

org.apache.cxf.common.i18n.UncheckedException: No operation was found with the name {http://impl.webservice.barcode.*****.com/}TestService.

解決過程：

      看報錯情況，好像是項目沒有查找到TestService這個方法，但是從wsdl中，可以看到，有存在這個方法。

      Attach cxf2.6.0的源碼進行跟蹤，後來發現，cxf會在其內部用一個map來保存QName,而這個map裏，有validCodeReq，但是前半部分不對，不是 {http://impl.webservice.barcode.*****.com/}，而是{http://webservice.barcode.*****.com/}。原來是命名空間的問題！返回服務端代碼，在服務實現類的註解

@WebService(targetNamespace = "http://webservice.barcode.*****.com/",
endpointInterface = "com.*****.barcode.webservice.WebServices") 

     這下，問題解決。

PS：從這個錯誤中可以看出，如若我們的webservice接口和實現類Impl放置在同一個包下，而不分包，就不會有這個錯誤。
