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 name="ServiceResponse">

      <wsdl:input message="tns:ServiceRequest" name="ServiceRequest">

      <wsdl:output message="tns:ServiceResponse" name="ServiceResponse">

    </wsdl:operation>
  </wsdl:portType>
  <wsdl:binding name="NotifyPortSoap11" type="tns:NotifyPort">

        <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：

<bean id="notify" name="notify" class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition">
    <!--<property name="createSoap12Binding" value="true" />-->
    <property name="portTypeName" value="NotifyPort" />
    <property name="locationUri" value="/ws" />
    <property name="schema">
        <bean class="org.springframework.xml.xsd.SimpleXsdSchema">
            <property name="xsd" value="notify.xsd" />
        </bean>
    </property>
    <property name="targetNamespace" value="http://fer2.klab/notify" />
    <!--<property name="soapActions">-->
        <!--<props>-->
            <!--<prop key="ServiceRequest">http://fer2.klab/notify/ServiceRequest"</prop>-->
        <!--</props>-->
    <!--</property>-->
</bean>

应用程序配置.xml：

    <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
    <property name="locations">

为什么生成的WSDL中的Service操作有空属性soapAction？

对 URL http://192.168.1.101:8080/fer2-0.0.1/ws 的 SOAP 请求，内容如下：

<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>

导致记录以下错误：

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

Answer 1

soap:operation 元素的soapAction 属性是将包含在 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，并且在创建存根时，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=""，这意味着请求所引用的操作在http请求的有效负载中指示。所以你的 wsdl 在这方面看起来不错。

虽然在Spring 中，您可以使用@SoapAction 注释方法，并且该方法将使用soapAction 标头映射。但是您在方法上使用了@PayloadRoot，因此它将使用本地名称'ServiceRequest'进行映射，因此soapAction的值将是""并且不会被使用。

Answer 2

问题终于解决了。

WSDL 是自动生成的并且是静态的。

Endpoint是这样改的（这里的重点是@Action注解）：

@Endpoint
public class NotifyEndPoint {

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

    @Autowired
    MainController mainController;

    @PayloadRoot(namespace = NAMESPACE_URL, localPart = "ServiceRequest")
    @Action("http://fer2.klab/notify/ServiceRequest")
//    @ResponsePayload
    public void send(@RequestPayload ServiceRequest hlMessage) {
        System.out.println("notify method");
        mainController.notify(null, "", hlMessage.getHL7Message());
    }

}

dispatcher-servlet.xml 改为：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:sws="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <sws:annotation-driven />

    <bean id="notify" name="notify" class="org.springframework.ws.wsdl.wsdl11.SimpleWsdl11Definition">
        <property name="wsdl" value="notify.wsdl" />
    </bean>

    <context:component-scan base-package="klab.fer2"/>

</beans>

Answer 3

对我来说它只工作（spring-boot 应用程序）：

Resolve empty soapAction

wsdl11Definition.setSoapActions(soapActions);

public class WebServiceConfig extends WsConfigurerAdapter {

@Bean(name = "someService")
public DefaultWsdl11Definition defaultWsdl11Definition(XsdSchema schema) {
    DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition();
    ....

    Properties soapActions = new Properties();
    for (Method method : endpointController.class.getMethods() ) {
        soapActions.setProperty(method.getName(), Const.NAMESPACE_URI + "/#" + method.getName());
    }
    wsdl11Definition.setSoapActions(soapActions);

    return wsdl11Definition;
}
