【问题描述】：

Soap 服务是远程托管的，但由于我们服务器的一些限制，我获得了 WSDL 并将其存储在本地。使用 maven、org.apache.cxf 插件和生成源命令我从本地 WSDL 生成了类。

WebServiceClient 类属性：

@WebServiceClient(name = "ManageCredit",
                  wsdlLocation = localWSDLAddress,
                  targetNamespace = targetNamespace)
public class ManageCredit extends Service 
    public final static URL WSDL_LOCATION;

    public final static QName SERVICE = new QName(targetNamespace, "ManageCredit");
    public final static QName ManageCreditEndpoint = new QName(targetNamespace, "ManageCreditEndpoint");
    static 
        URL url = null;
        try 
            url = new URL(localWSDLAddress);
         catch (MalformedURLException e) 
            java.util.logging.Logger.getLogger(ManageCredit.class.getName())
                .log(java.util.logging.Level.INFO,
                     "Can not initialize the default wsdl from 0", localWSDLAddress);
        
        WSDL_LOCATION = url;
    

客户端设置：

ManageCredit manageCreditService = new ManageCredit();
ManageCreditPortType manageCreditPortType = manageCreditService.getManageCreditEndpoint();
SignContractRequest signContractRequest = new SignContractRequest();
signContractRequest.setRequestID("123");
signContractRequest.setApplicationID("1111");
signContractRequest.setChannelID("someValue");
manageCreditPortType.signContract(signContractRequest);

使用此代码，调用 http://localhost:8080/.... 我需要调用远程服务器，例如https://example.google:1820，而不是本地主机。如何在不更改 wsdl 位置的情况下更改客户端调用的端点。

【参考方案1】：

由于您在本地下载了 WSDL，因此您现在可以控制它。因此，如果您将 WSDL 文件本身中的 SOAP 地址更改为指向您想从客户端调用的任何地址，它可能会起作用。

或者，您可以尝试使用BindingProvider.ENDPOINT_ADDRESS_PROPERTY，如here 所示，尽管据我记得您需要为每个请求执行此操作，而不是为整个服务客户端配置它：

MyService service = new MyService(wsdlURL, serviceName);
ServicePort client = service.getServicePort();
BindingProvider provider = (BindingProvider)client;
// You can set the address per request here
provider.getRequestContext().put(
     BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
     "http://my/new/url/to/the/service");

【参考方案2】：

您应该将 wsdl 文件复制到 src/main/resources 文件夹下的某个位置，以便将其打包到项目的 jar 文件中（对于下面的示例，我使用 src/main/resources/META-INF/wsdl）。配置cxf-codegen-plugin时，指定wsdlLocation配置值，如下图。

<plugin>
  <groupId>org.apache.cxf</groupId>
  <artifactId>cxf-codegen-plugin</artifactId>
  <version>3.3.0</version>
  <executions>
    <execution>
      <id>my-wsdl</id>
      <phase>generate-sources</phase>
      <goals>
        <goal>wsdl2java</goal>
      </goals>
      <configuration>
        <encoding>UTF-8</encoding>
        <wsdlOptions>
          <wsdlOption>
            <wsdl>$project.basedir\src\main\resources\META-INF\wsdl\helloWorld.wsdl</wsdl>
            <wsdlLocation>classpath:/META-INF/wsdl/helloWorld.wsdl</wsdlLocation>
          </wsdlOption>
        </wsdlOptions>
      </configuration>
    </execution>
  </executions>
</plugin>

然后您生成的 WebServiceClient 代码应该从类路径加载 wsdl，类似于此...

@WebServiceClient(name = "HelloWorldService",
                  wsdlLocation = "classpath:/META-INF/wsdl/helloWorld.wsdl",
                  targetNamespace = "http://example.com/helloWorld")
public class HelloWorldService extends Service 

    public final static URL WSDL_LOCATION;

    public final static QName SERVICE = new QName("http://example.com/helloWorld", "HelloWorldService");
    public final static QName HelloWorldProxyPort = new QName("http://example.com/helloWorld", "HelloWorldProxyPort");
    static 
        URL url = HelloWorldService.class.getClassLoader().getResource("/META-INF/wsdl/helloWorld.wsdl");
        if (url == null) 
            url = HelloWorldService.class.getClassLoader().getResource("META-INF/wsdl/helloWorld.wsdl");
        
        if (url == null) 
            java.util.logging.Logger.getLogger(HelloWorldService.class.getName())
                .log(java.util.logging.Level.INFO,
                     "Can not initialize the default wsdl from 0", "classpath:/META-INF/wsdl/helloWorld.wsdl");
        
        WSDL_LOCATION = url;
    

    ...

使用服务时，可以为服务设置端点地址如下...

HelloWorldService helloWorldService = new HelloWorldService();
HelloWorldPort client = service.getHelloWorldPort();
BindingProvider provider = (BindingProvider)client;
// You can set the address per request here
provider.getRequestContext().put(
     BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
     "http://my/new/url/to/the/service");

【讨论】：

谢谢。那行得通

你能把它标记为接受的答案吗？
