我要把电视放进去 wsa:To header，与扩展webservicegatewaysupport的客户端（端点的url）不同的值。
现在我这样使用服务：

public class HelloClient extends WebServiceGatewaySupport {
    public GetHelloResponse getHello(GetHelloRequest request) throws URISyntaxException {
        ActionCallback callback = new ActionCallback(
            new URI("urn", "test:mdm:system:epage:b2b:logs:hello", null),
            new Addressing10()
            );
        return (GetHelloResponse) getWebServiceTemplate()
            .marshalSendAndReceive(request, callback);
    }
}

在soap客户端配置类中：

@Bean
    public HelloClient getHelloClient() throws Exception {
        HelloClient helloClient = new HelloClient();
        helloClient.setMarshaller(getMarshaller());
        helloClient.setUnmarshaller(getMarshaller());
        helloClient.setDefaultUri(env.getProperty("uri.gethelloclient"));
        ClientInterceptor[] interceptors = new ClientInterceptor[] {
                securityInterceptor()
        };
        helloClient.setInterceptors(interceptors);
        return helloClient;
    }

在soap头中，结果如下：

<SOAP-ENV:Header>
  ...
  <wsa:To SOAP-ENV:mustUnderstand="1">http://localhost:8080/ws/hello</wsa:To>
  <wsa:Action>urn:antel:mdm:system:epagos:b2b:comercio:hola</wsa:Action>
  <wsa:MessageID>urn:uuid:27774d62-5867-47ec-b463-f50f702f4ae8</wsa:MessageID>
</SOAP-ENV:Header>

我阅读了官方文件中的参考资料，但没有提到这一点。
