java - 获取 CXF 错误 : javax. xml.ws.WebServiceException:WSDL 元数据不可用于创建代理

Question

我已经使用 CXF 的 wsdl2java 从 WSDL 文件生成代码。然后，我使用 ant 构建 xml 文件(也由 CXF 的 wsdl2java 生成)构建代码。

当我在我的本地 Java 7 机器上运行我的代码时，一切都很好。当我在运行 Java 1.5 的云中的 linux 机器上运行代码时，出现以下错误:

javax.xml.ws.WebServiceException: WSDL Metadata not available to create the proxy,
either Service instance or ServiceEndpointInterface com.a.b.TheService should have
WSDL information

我四处搜索，但找不到任何可能解释我的场景中的错误的信息。我不确定从哪里开始。任何人都可以阐明吗？

我在上面提到了 Java 版本，因为这是一个明显的差异，但它可能与问题无关。

更新:应 Syon 的要求添加以下代码:

private static final String servicesNamespace = "http://www.serviceprovider.com/services/2009/03/02";
private static final String servicesNamespaceSchema = "http://www.serviceprovider.com/services/2009/03/02/schema";
private static String SERVICE_NAME = "TheService";
private QName SERVICE_QNAME;
private TheService m_theService;
...

SERVICE_QNAME = new QName(servicesNamespace, SERVICE_NAME);

I wrote this code quite some time ago, and at the time I wrote the comment below.
I've included it here in case it is helpful:

// The sample code creates an instance of the generated TheService_Service class.
// TheService_Service has references to the local WSDL file that it was generated from, and
// will report an error if it is not found. To prevent that error, we could:
// (1) ensure that the WSDL is available locally in the production environment in the location
//     referenced in the generated Java
// (2) generate the Java from the WSDL located on the web rather than local WSDL, meaning that
//     the WSDL referenced in the generated Java would be a URL to where it is located on
//     serviceproviders's web site.
// (3) Rather than create an instance of TheService_Service, just create an instance of its
//     super class, javax.xml.ws.Service, which has a static method to create an instance of it that
//     does not require the location of the WSDL to be passed to it.
// I am going to choose option (3). Option (2) is a close second.

Service service = Service.create(SERVICE_QNAME);
m_theService = service.getPort(TheService.class);   <-- Fails here

((BindingProvider)m_theService).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endpointAddress);

Binding binding = ((BindingProvider)m_theService).getBinding();
((SOAPBinding)binding).setMTOMEnabled(false);

谢谢，

据我所知，JAX-WS/CXF 始终需要 WSDL。会不会是您的 WSDL 包含在本地机器某处的类路径中，而不是在您的 linux 机器上？

无论如何，您应该能够使用 Service.create(URL, QNAME) 方法解决此问题。该 URL 需要指向 WSDL，您可以在末尾使用 Web 服务端点 + ?wsdl，或者在本地保存 WSDL 的副本并改为指向它。

在您的评论中，您提到在 Web 上引用 WSDL 更为可取。我个人会将其存储在本地，因为这会提高调用 Web 服务时的性能。每次您创建代理时，该框架都不需要通过网络调用来获取 WSDL。
