spring集成：SpelEvaluationException：EL1004E :(方法8）：方法調用：方法getResponseForSample（javax.xml.bind.JAXBElement）

我是Spring集成中的新成員，並且在解組SOAP時遇到問題。我有以下示例XSD：spring集成：SpelEvaluationException：EL1004E :(方法8）：方法調用：方法getResponseForSample（javax.xml.bind.JAXBElement）

現在我已經創建使用jaxbmarshaller XJC編譯java文件，生成以下是objectFactory對象file.other文件FFSampleRequest，FFSampleResponse，GetResponseForSample，GetResponseForSampleResponse，包信息。把所有這些文件在

web.xml文件來處理SOAP請求：

<servlet> 
     <servlet-name>spring-ws</servlet-name> 
     <servlet-class>org.springframework.ws.transport.http.MessageDispatcherServlet</servlet-class> 
     <init-param>

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

和使用的配置文件中的以下設置用於調用服務方法，這個請求：

<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">

    </bean> 

<int:service-activator input-channel="FFSampleRequestChannel">

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

我的soap請求成功地點擊了服務類，但是我收到異常。

/**

    @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 ; 

     } 
    }

SOAP請求是如下：

<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>

我改變下面的服務方法的參數，但是當我嘗試接收的值在SOAP消息中給出的不是綁定，而是爲「SampleType」和「Timestamp」獲取空值。

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;*/ 
     }

我懷疑的是，在對象工廠創建的條目是不正確的，因爲覺得我面對的挑戰，因爲這些條目只（下面的條目）。請讓我知道，如果我們有任何限制使用jAXBMARSHALLER和xjc編譯器與Spring集成進行編組/解組的目的，因爲我面臨着許多來自xjc生成的java對象的soap映射的挑戰。請提供您的inpur並讓我知道我缺少綁定我的soap參數的地方。

/** 
    * 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); 
    }

我從來沒有使用JAXBElement，但它可能是有用的。我生成XSD類和它們標記爲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; 
}

而且只有手動使用ObjectFactory，不依賴於JAXB魔法。

這足以讓我根據入站XML獲取正確的模型對象。

從另一方面來說，如果您使用FFSampleImpl作爲Spring集成<service-activator>，那麼沒有理由用Spring-WS註釋標記它的方法。

非常感謝Artem。實際上，jaxbmarshaller xjc創建的文件並不總是正確的，但卻是真實的。我在Pojo文件和對象工廠手動更正了條目，現在這工作正常。 – user3777801

很高興聽到！ :-) –
