如何使Java Web服务客户端在执行时获取并解析WSDL？

Question

I've created java webservices and clients using Netbeans. However, the clients seem to have the WSDL already 'built-in'.

Is there an easy way of making my client fetch and parse the WSDL code upon execution, so that if the webservice moves to another server, the client is just invoked with a different commandline argument for where to find the webservice?

Answer 1

NetBeans' auto-generated proxy factory provides two constructors.

The nullary one initializes the factory to the hardcoded URI provided to the "New Web Service Client from WSDL..." dialogue.

The second constructor accepts a URL to the WSDL documentation, and the service QName.

When you have NetBeans insert the service call into your source code, the code fragment it generates uses the nullary constructor, but you can manually change that.

// alternate constructor: SampleDomainService(URL, QName)
SampleDomainService service = new SampleDomainService();
SampleDomain port = service.getSampleDomainPort();
SampleDomainRequestType request = new SampleDomainRequestType();
SampleDomainResponseType result = port.sampleOperation(request);

Answer 2

您是否考虑过让客户端根本不使用WSDL中的服务器URL，而仅使用为其配置服务器地址？

Answer 3

大多数自动生成的客户端允许您指定WSDL URL的位置，即使其中一个是硬编码的（例如，使用CXF进行编码）。
