Jaxb在Unmarshalling嵌套Soap Message上赋予null

Question

我需要使用jaxb取消对java对象的嵌套soap响应。但我总是得到一个空指针异常。

我已经检查了几乎所有链接，如下所示： jaxb unmarshalling returns null jaxb unmarshalling giving NULL to anytype element in xsd

但没有任何事情可以帮助我。

这是我的肥皂回应消息

<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsap.org/sap/env/' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
   <soapenv:Body>
      <ns1:subscribeProductResponse xmlns:ns1='http://www.csapi.org/schema/parlayx/subscribe/manage/v1_0/local'>
         <ns1:subscribeProductRsp>
            <result>22007233</result>
            <resultDescription>Temporary Order saved successfully! DataSendStep finish end.</resultDescription>
         </ns1:subscribeProductRsp>
      </ns1:subscribeProductResponse>
   </soapenv:Body>
</soapenv:Envelope>

以下是我的Java Pojo类

@XmlRootElement (name="subscribeProductResponse",namespace="http://www.csapi.org/schema/parlayx/subscribe/manage/v1_0/local")
@XmlAccessorType(XmlAccessType.FIELD)
public class SubscribeProductResponse {
//  @XmlElementWrapper
    @XmlElement(name="subscribeProductRsp")
    private SubscribeProductRsp subscribeProductRsp;

    public SubscribeProductRsp getSubscribeProductRsp() {
        return subscribeProductRsp;
    }

        public void setSubscribeProductRsp(SubscribeProductRsp subscribeProductRsp) {
        this.subscribeProductRsp = subscribeProductRsp;
    }



}

@XmlRootElement(name="subscribeProductRsp")
public class SubscribeProductRsp {

    private String result;

    private String resultDescription;

    public String getResult() {
        return result;
    }

    @XmlElement(name = "result", required = true)
    public void setResult(String result) {
        this.result = result;
    }

    public String getResultDescription() {
        return resultDescription;
    }
    @XmlElement(name = "resultDescription", required = true)
    public void setResultDescription(String resultDescription) {
        this.resultDescription = resultDescription;
    }

    @Override
    public String toString() {
        return "ClassPojo [result = " + result + ", resultDescription = "
                + resultDescription + "]";
    }
}

以下是解组响应消息的代码

    JAXBContext jc = JAXBContext.newInstance(SubscribeProductResponse.class);
       Unmarshaller um = jc.createUnmarshaller();
       SubscribeProductResponse output = (SubscribeProductResponse)um.unmarshal(soapResponse.getSOAPBody().extractContentAsDocument());

       System.out.println(output.getSubscribeProductRsp().getResult());

    JAXBContext jc = JAXBContext.newInstance(SubscribeProductResponse.class);
   Unmarshaller um = jc.createUnmarshaller();
   SubscribeProductResponse output = (SubscribeProductResponse)um.unmarshal(soapResponse.getSOAPBody().extractContentAsDocument());

   System.out.println(output.getSubscribeProductRsp().getResult());

我将output.getSubscribeProductRsp（）视为null

任何人都可以告诉我我做错了什么。
