使用 HTTPS 的 Web 服务

Question

我有一个外部 Web 服务，它通过 https 工作，我可以使用 wsimport 生成 java 类，但是当我调用该服务时，我收到以下异常：

Exception in thread "main" com.sun.xml.internal.ws.client.ClientTransportException: HTTP transport error: java.net.UnknownHostException: ECM01
at com.sun.xml.internal.ws.transport.http.client.HttpClientTransport.getOutput(Unknown Source)

at java.net.SocksSocketImpl.connect(Unknown Source)
at java.net.Socket.connect(Unknown Source)
at java.net.Socket.connect(Unknown Source)
at sun.net.NetworkClient.doConnect(Unknown Source)

我调用服务的类是这样的：

public static void main(String[] args) {
    ColleagueServiceService cs = new ColleagueServiceService();
    ColleagueService service = cs.getColleagueServicePort();

    try {
        service.getColleagues("user", "password", 1);
    } catch (Exception_Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

我尝试使用 SoapUI 调用 web 服务，但它显示另一个异常：

已编辑：

这个网络服务是我的，但它在一个外部服务器中，我看到我的班级 ColleagueService（不是我做的）它的注释是：

@WebService(serviceName="ColleagueServiceService")
@SOAPBinding(style = SOAPBinding.Style.RPC, use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)
public class ColleagueService {

生成的 wsdl 我有这个：

<port binding="tns:ColleagueServiceBinding" name="ColleagueServicePort">
    <soap:address location="http://ECM01:80/services/ColleagueService"/>
</port>

外部服务器（一个客户端）有一个 jboss 服务器和一个 apache http 服务器，http 服务器通过 ProxyPass 将所有请求重定向到路径 /services/ 到 jboss 服务器（jboss 服务器是主机 ECM01），无论如何 wsdl 是错误的因为服务是 https 并且在 wsdl 我有 http

有人可以帮忙吗？谢谢。

Answer 1

原因：java.net.UnknownHostException: ECM01

这是 WSDL 中指定的主机吗？寻找这样的部分：

<wsdl:port binding="tns:FooBinding" name="FooPort">
  <soap:address location="https://ECM01/FooService"/>
</wsdl:port>

如果是这样，您必须在端口上set the endpoint：

BindingProvider bindingProvider = (BindingProvider) port;
bindingProvider.getRequestContext()
    .put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endpoint);

这将是其他任务的补充，例如提供proxy configuration 作为Anders R. Bystrup 提及和（可能）configuring SSL client certificates。

WSDL 不反映真实的服务端点是完全正常的。在我工作过的任何地方，都会使用已知的错误 URI（例如，本地主机，其中所有内容都分布在不同的主机上。）客户端可以通过配置机制显式设置端点（请参阅上面的 JAX-WS 客户端代码。）这允许灵活性在开发期间并防止在从开发过渡到生产期间使用错误的主机。

也就是说，当使用自动生成的 WSDL 时，我认为如何生成 SOAP 地址元素是您的 JAX-WS 实现的一个实现细节。我不确定，因为我从来没有依赖过它。我会参考您的容器实现的文档。
