java - WSDL 操作中的soapAction 属性为空

Question

有一个具有以下 WSDL 的 Web 服务:

<?xml version="1.0" encoding="UTF-8" standalone="no"?><wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:sch="http://fer2.klab/notify" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://fer2.klab/notify" targetNamespace="http://fer2.klab/notify">

            </xs:sequence>
        </xs:complexType>
    </xs:element>
    <xs:element name="ServiceResponse">
        <xs:complexType>
            <xs:sequence>
                <xs:element maxOccurs="1" minOccurs="1" name="response" type="xs:string"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

  </wsdl:types>
  <wsdl:message name="ServiceResponse">
    <wsdl:part element="tns:ServiceResponse" name="ServiceResponse">

  </wsdl:message>
  <wsdl:message name="ServiceRequest">
    <wsdl:part element="tns:ServiceRequest" name="ServiceRequest">
    </wsdl:part>
  </wsdl:message>
  <wsdl:portType name="NotifyPort">
    <wsdl:operation name="Service">
      <wsdl:input message="tns:ServiceRequest" name="ServiceRequest">
    </wsdl:input>
      <wsdl:output message="tns:ServiceResponse" name="ServiceResponse">
    </wsdl:output>
    </wsdl:operation>
  </wsdl:portType>
  <wsdl:binding name="NotifyPortSoap11" type="tns:NotifyPort">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>

      <wsdl:input name="ServiceRequest">
        <soap:body use="literal"/>
      </wsdl:input>
      <wsdl:output name="ServiceResponse">
        <soap:body use="literal"/>
      </wsdl:output>
    </wsdl:operation>
  </wsdl:binding>
  <wsdl:service name="NotifyPortService">
    <wsdl:port binding="tns:NotifyPortSoap11" name="NotifyPortSoap11">
      <soap:address location="http://192.168.1.101:8080/fer2-0.0.1/ws"/>
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

有一个端点:

@Endpoint
public class NotifyEndPoint {

    private static final String NAMESPACE_URL = "http://fer2.klab/notify";

    @Autowired
    MainController mainController;

    @PayloadRoot(namespace = NAMESPACE_URL, localPart = "ServiceRequest")
    @ResponsePayload
    public ServiceResponse send(@RequestPayload ServiceRequest hlMessage){
        System.out.println("notify method");
        Object resp = mainController.notify(null, "", hlMessage.getHL7Message());
        ServiceResponse sr = new ServiceResponse();
        if (resp != null){
            sr.setResponse(resp.toString());
        }
        else{
            sr.setResponse("null");
        }

        return sr;
    }
}

调度程序servlet.xml:

为什么 Service生成的 WSDL 中的操作具有空属性 soapAction ?

对 URL 的 SOAP 请求 http://192.168.1.101:8080/fer2-0.0.1/ws具有以下内容:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:not="http://fer2.klab/notify">
   <soapenv:Header/>
   <soapenv:Body>
      <not:ServiceRequest>
         <not:HL7message>hdfghdfghdfgh</not:HL7message>
      </not:ServiceRequest>
   </soapenv:Body>
</soapenv:Envelope>

结果记录了以下错误:

 org.springframework.ws.server.EndpointNotFound- No endpoint mapping found for [SaajSoapMessage {http://fer2.klab/notify}ServiceRequest]

Answer 1

soapAction soap:operation 的属性element 是将包含在 HTTP 请求消息中的值，如下所示:

POST /StockQuote HTTP/1.1
Content-Type: text/xml; charset="utf-8"
Content-Length: nnnn
SOAPAction: "http://electrocommerce.org/abc#MyMessage"

如 specification 中所述此值仅指示将调用哪个操作的意图，并且在创建 stub 时 Web 服务框架通常不使用它。

一个常见的模式是将其设置为空字符串，如 <soap:operation soapAction=""这意味着请求所指的操作在 http 请求的有效负载中指明。所以你的 wsdl 在这方面看起来不错。

在 Spring但是，您可以使用 @SoapAction 注释方法并且该方法将使用soapAction header 进行映射。但是您正在使用 @PayloadRoot在您的方法上，因此它将使用本地名称“ServiceRequest”进行映射，因此soapAction 的值将为 ""它不会被使用。
