Question

我想在Spring MVC应用程序中添加一个可消耗合同优先的Web服务 - 该应用程序是Web服务提供者。在web.xml中，我添加了第二个应该处理请求的servlet：

<servlet>
    <servlet-name>webservices</servlet-name>
    <servlet-class>org.springframework.ws.transport.http.MessageDispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:/webservices-servlet.xml</param-value>
    </init-param>
    <init-param>
        <param-name>transformWsdlLocations</param-name>
        <param-value>true</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>webservices</servlet-name>
    <url-pattern>/services/*</url-pattern>
</servlet-mapping>

webservices-servlet.xml包含：

<context:component-scan base-package="de.y.application" />

<sws:static-wsdl id="yAdaptorService" location="/WEB-INF/wsdl/yAdapterService.wsdl" />

<bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping">
    <property name="interceptors">
        <list>
            <bean
                class="org.springframework.ws.server.endpoint.interceptor.PayloadLoggingInterceptor" />
            <bean
                class="org.springframework.ws.soap.server.endpoint.interceptor.PayloadValidatingInterceptor">
                <property name="schema" value="/WEB-INF/wsdl/ResourceAdapter.xsd" />
                <property name="validateRequest" value="true" />
                <property name="validateResponse" value="true" />
            </bean>
        </list>
    </property>
    <property name="order" value="1" />
</bean>

在Tomcat 7中部署和启动应用程序时，将部署WSDL http://localhost:8080/application/services/yAdapterService.wsdl

相关的WSDL片段：

<message name="pingRequest">
</message>
<message name="pingResponse">
</message>
<portType name="yAdaptor">
    <operation name="ping">
        <input message="tns:pingRequest"></input>
        <output message="tns:pingResponse"></output>
    </operation>
</portType>
<binding name="SoapBinding" type="tns:yAdapter">
    <wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <operation name="ping">
        <wsdlsoap:operation soapAction="urn:webservice.y.x.com:wsdl/ping"/>
        <input>
            <wsdlsoap:body use="literal"/>
        </input>
        <output>
            <wsdlsoap:body use="literal"/>
        </output>
    </operation>
</binding>
<service name="yAdapterService">
    <port binding="tns:SoapBinding" name="yAdapterSoapPort">
        <wsdlsoap:address location="http://localhost:8080/application/services/yAdapterService"/>
    </port>
</service>

将logger设置为调试级别，Tomcat在启动时告诉我：

09 Jan 2014 12:20:49,247 DEBUG org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping:105 - Mapped [{urn:webservice.x.com:wsdl}ping] onto endpoint [public void de.y.yAdapterService.ping()]

但是当谈到通过SOAP-UI的简单ping请求时

SOAPAction: urn:webservice.x.com:wsdl/ping

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <soapenv:Header/>
    <soapenv:Body/>
</soapenv:Envelope>

到此端点

private static final String NAMESPACE_URI   = "urn:webservice.x.com:wsdl";

@Override
@PayloadRoot(localPart = "ping", namespace = NAMESPACE_URI)
public void ping()
{
    System.out.println("ping pong");
}

无法找到映射的端点

/* SOAP-UI REQUEST ON urn:webservice.x.com:wsdl/ping */

我错过了什么？为什么找不到最初映射的端点？

Answer 1

最后我发现SOAP-UI在解析WSDL时使用了错误的命名空间。正确的请求消息是：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:webservice.x.com:wsdl">
    <soapenv:Header/>
    <soapenv:Body>
        <urn:ping/>
    </soapenv:Body>
</soapenv:Envelope>

Spring WS似乎忽略了映射端点
