CXF2.7.0配置REST和spring時報錯：Error creating bean with name '***': Invocation of init method failed; nested exception is ***.ServiceConstructionException

今天配置CXF2.7.0的REST和spring時一直再報：

Error creating bean with name '***': Invocation of init method failed; nested exception is org.apache.cxf.service.factory.ServiceConstructionException的錯誤，查看了自己的application-server.xml里面的bean配置沒問題，找了一下午，最后發現是jar包沖突。

解釋是：

CXF bug.  You can remove the cxf-services-ws-discovery-service-2.7.0.jar from the lib dir and it should "fix" this. 

意思就是刪除cxf-services-ws-discovery-service-2.7.0.jar這個jar包。

問題解決....
