spring integration：SpelEvaluationException：EL1004E：（pos 8）：方法调用：方法getResponseForSample（javax.xml.bind.JAXBElement）

Question

我是Spring集成的新手，在解组SOAP请求时遇到了问题。我有以下示例xsd：

        </xs:sequence>
    </xs:complexType>
</xs:schema>

现在我使用jaxbmarshaller xjc编译器创建了java文件，下面是objectFactory文件。生成的其他文件是FFSampleRequest，FFSampleResponse，GetResponseForSample，GetResponseForSampleResponse，package-info。将所有这些文件放在

用于处理soap请求的web.xml文件：

<servlet>
        <servlet-name>spring-ws</servlet-name>
        <servlet-class>org.springframework.ws.transport.http.MessageDispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>WEB-INF/spring-ws-config.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>spring-ws</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>

并使用配置文件中的以下设置来调用此请求的服务方法：

<int:channel id="FFSampleRequestChannel"/>

<int-ws:inbound-gateway id="ws-ffsample-gateway" request-channel="FFSampleRequestChannel" marshaller="marshaller" unmarshaller="marshaller"/>

<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
    <property name="contextPath" value="com.java.MyChannel.model" />
    </bean>

<int:service-activator input-channel="FFSampleRequestChannel">
    <bean class="com.java.MyChannel.serviceImpl.FFSampleImpl">
    <constructor-arg ref = "ffSampleRequest"></constructor-arg>

<bean id="ffSampleRequest" class="com.java.MyChannel.model.FFSampleRequest"></bean>
    <bean id="ffSampleResponse" class="com.java.MyChannel.model.FFSampleResponse"></bean>

我的soap请求成功点击服务类但我得到例外。

  /**
     * @author Vinay Agrawal
     */
    @XmlRegistry
    public class FFSampleImpl implements FFSampleInterface
    {

        @Autowired
        FFSampleRequest request;
        @Autowired
        FFSampleJdbc ffSampleJdbc;
        public FFSampleImpl() {
        }

        public FFSampleImpl(FFSampleRequest request) {
            super();
            this.request = request;
        }

        @Override
        @PayloadRoot(localPart = "getResponseForSample" , namespace = "http://tempuri.org/")
        @ResponsePayload
        public FFSampleResponse getResponseForSample(@RequestPayload FFSampleRequest request){
            List<FFSampleResponse> ffSampleResponse = new ArrayList<FFSampleResponse>();

            return ffSampleResponse ;

        }
    }

肥皂请求如下：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://tempuri.org/">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:getResponseForSample>
         <!--Optional:-->
         <arg0>

            <ser:Timestamp>"100"</ser:Timestamp>
            <ser:SampleType>15</ser:SampleType>
         </arg0>
      </ser:getResponseForSample>
   </soapenv:Body>
</soapenv:Envelope>

我收到以下例外情况：

我更改了下面的服务方法参数但是当我尝试接收SOAP消息中给出的值时没有绑定，并且我得到＆＃34; SampleType＆＃34;和＆＃34;时间戳＆＃34;。

  public class FFSampleImpl implements FFSampleInterface
    {

        @Autowired
        FFSampleRequest request;
        public FFSampleImpl() {
        }

        public FFSampleImpl(FFSampleRequest request) {
            super();
            this.request = request;
        }

        @Override
        @PayloadRoot(localPart = "getResponseForSample" , namespace = "http://tempuri.org/")
        @ResponsePayload
        public FFSampleResponse getResponseForSample(@RequestPayload JAXBElement<FFSampleRequest> ffreq){
            FFSampleResponse ffSampleResponse2 = new FFSampleResponse();
            return ffSampleResponse2;

        /*  return FFSampleResponse;*/
        }

我怀疑在对象工厂中创建的条目不正确，因为我觉得我因为这些条目而面临挑战（在条目下面）。如果我们对使用jAXBMARSHALLER和xjc编译器以及用于编组/解组目的的spring集成有任何限制，请告诉我，因为我面临着来自xjc生成的java对象的soap映射的许多挑战。请提供你的inpur，让我知道我的肥皂参数绑定缺失的地方。

/**
     * Create an instance of {@link JAXBElement }{@code <}{@link GetResponseForSample }{@code >}}
     * 
     */
    @XmlElementDecl(namespace = "http://tempuri.org/", name = "getResponseForSample")
    public JAXBElement<FFSampleRequest> createGetResponseForSample(FFSampleRequest value) {
        return new JAXBElement<FFSampleRequest>(_GetResponseForSample_QNAME, FFSampleRequest.class, null, value);
    }

    /**
     * Create an instance of {@link JAXBElement }{@code <}{@link GetResponseForSampleResponse }{@code >}}
     * 
     */
    @XmlElementDecl(namespace = "http://tempuri.org/", name = "getResponseForSampleResponse")
    public JAXBElement<GetResponseForSampleResponse> createGetResponseForSampleResponse(GetResponseForSampleResponse value) {
        return new JAXBElement<GetResponseForSampleResponse>(_GetResponseForSampleResponse_QNAME, GetResponseForSampleResponse.class, null, value);
    }

Answer 1

我从未使用JAXBElement，但它可能有用。 我为XSD生成类并将它们标记为JaxB元素，例如：

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "feeRequest", propOrder = {
        "billerId",
        "amount"
})
@XmlRootElement(name = "feeRequest")
public class FeeReqData {

    @XmlElement(required = true)
    protected Long billerId;

    @XmlElement(required = true)
    protected Double amount;
}

仅手动使用ObjectFactory并且不依赖于JaxB魔法。

这足以让我根据入站XML获取正确的模型对象。

另一方面，如果您使用FFSampleImpl作为Spring Integration <service-activator>，则没有理由使用Spring-WS注释标记其方法。
