我使用 CXF 的 wsdl2java 从 WSDL 文件生成代码。然后,我使用 ant 构建 xml 文件(也是由 CXF 的 wsdl2java 生成)构建代码。
当我在本地 Java 7 计算机上运行代码时,一切正常。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
我进行了搜索,但找不到任何可以解释我的场景中的错误的信息。我不知道从哪里开始处理这个问题。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:根据 Syon 的请求添加以下代码:
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

最佳答案
据我所知,JAX-WS/CXF 始终需要 WSDL。是否您的 WSDL 包含在本地计算机上某处的类路径中,但不在 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。 URL 需要指向 WSDL,您可以使用 Web 服务端点 + 最后的 ?wsdl
,或者在本地保存 WSDL 的副本并指向该副本。
在您的评论中,您提到最好引用网络上的 WSDL。就我个人而言,我会将其存储在本地,因为这将提高调用 Web 服务时的性能。每次创建代理时,框架不需要通过网络进行调用来获取 WSDL。
