推荐答案
您无需生成代码即可使用 JAX-WS 客户端 - example - 但你需要了解一些关于请求/响应形式的信息以调用服务并解释响应.
You don't need to generate code to use JAX-WS clients - example - but you'll need to know something about the form of the requests/responses in order to invoke the service and interpret the response.
WSDL 描述了 SOAP 有效负载的形式.SOAP 有效负载可以包含各种复杂的 XML 结构.服务可能能够在合同中描述它的所有约束，但可能有逻辑约束不是.您可以从 WSDL 推断出有限数量的事情.
The WSDL describes the form of the SOAP payloads. SOAP payloads can contain all sorts of complex XML structures. The service might be able to describe all its constraints in the contract, but there may be logical constraints that aren't. There are a finite number of things you can infer from the WSDL.
