java - CXF WebService 测试期间 JAXB 中的 SAXParseException

Question

我是 JAXB 新手。我获得了一个 wsdl 文件，我使用 apache-cxf 实用程序 wsdl2java 来获取许多 Java 类，从中我实现了我的 Web 服务。但是当我在服务上启动客户端服务器测试时，出现以下异常:

мар 25, 2013 12:19:36 PM org.apache.cxf.wsdl.EndpointReferenceUtils createSchema
WARNING: SAXException for newSchema()
org.xml.sax.SAXParseException; src-import.1.1: The namespace attribute 'http://www.aaa.com/bbb/ccc/ddd' of an <import> element information item must not be the same as the targetNamespace of the schema it exists in.

为什么这个中间 XML 会生成为导入自身？可以以某种方式取消此导入标签的出现吗？我想，原因可能是在最初的 wsdl 中，或者可能是一些错误。

问题是因为在我生成的 ProxyServiceImpl 类中，我在 @WebService 注释中缺少 wsdlLocation:

@javax.jws.WebService(
                  serviceName = "ServiceName",
                  portName = "ServicePort",
                  targetNamespace = "http://www.aaa.com/bbb/ccc/ddd",
                  wsdlLocation = "path_to_wsdl",
                  endpointInterface = "ProxyService_class")

当我添加它时，一切正常。
