Question

我有以下xml响应：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:DealLookupResponse xmlns:ns2="http://www.starstandards.org/webservices/2005/10/transport" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:type="xsd:anyType">
    <Deal>
        <CompanyNumber>CN7</CompanyNumber>
        <DealNumber>111</DealNumber>
        <RecordStatus>A</RecordStatus>
        <SalesPersons>
            <SalesPerson>
                <RecordType/>
                <SalesPersonID>CL1</SalesPersonID>
                <Status>A</Status>
                <SaleDate>20140806</SaleDate>
                <SalesPersonName>CLOSER 1</SalesPersonName>
                <IncentiveCommission>0.00</IncentiveCommission>
                <TotalCommission>0.00</TotalCommission>
            </SalesPerson>
        </SalesPersons>
    </Deal>
</ns2:DealLookupResponse>

当我将这个xml解组为Java Object时，我获得了Deal对象的所有值，但SalesPersons在列表中有一个元素，并且该元素的所有属性都为null。我错过了什么？

我的DealLookupResponse类是

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "deal"
})
@XmlRootElement(name = "DealLookupResponse", namespace="http://www.starstandards.org/webservices/2005/10/transport")

public class DealLookupResponse {

    @XmlElement(name = "Deal", required = false)
    Deal deal;

    public Deal getDeal() {
       return deal;
    }

    public void setDeal(Deal deal) {
       this.deal = deal;
    }
}

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Deal", propOrder = {
    "companyNumber",
    "dealNumber",
    "recordStatus",
    "salesPersons"
}, namespace = "http://www.starstandards.org/webservices/2005/10/transport")
public class Deal {

    @XmlElement(name="CompanyNumber")
    String companyNumber;

    @XmlElement(name="DealNumber")
    String dealNumber;

    @XmlElement(name="RecordStatus")
    String recordStatus;

    @XmlElementWrapper
    @XmlElement(name="SalesPerson")
    List<SalesPerson> salesPersons;
}

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "SalesPerson", propOrder = {
    "recordType",
    "salesPersonID",
    "status",
    "saleDate",
    "salesPersonName",
    "incentiveCommission",
    "totalCommission"
}, namespace = "http://www.starstandards.org/webservices/2005/10/transport")

public class SalesPerson {

   @XmlElement(name="RecordType")
   String recordType;

   @XmlElement(name="SalesPersonID")
   Long salesPersonID;

   @XmlElement(name="Status")
   String status;

   @XmlElement(name="SaleDate")
   Date saleDate;

   @XmlElement(name="SalesPersonName")
   String salesPersonName;

   @XmlElement(name="IncentiveCommission")
   Double incentiveCommission;

   @XmlElement(name="TotalCommission")
   Double totalCommission;

}

我的解组代码如下所示：

    JAXBContext jc =  JAXBContext.newInstance(DealLookupResponse.class);
    Unmarshaller unmarshaller = jc.createUnmarshaller();
    DealLookupResponse je = (DealLookupResponse)unmarshaller.unmarshal(xmlInputSource);

Answer 1

您目前拥有的

由于您未在name注释中指定@XmlElementWrapper，因此您将获得默认行为。

@XmlElementWrapper
@XmlElement(name="SalesPerson")
List<SalesPerson> salesPersons;

这意味着它将对应于以下XML：

<salesPersons>
    <SalesPerson>
    </SalesPerson>
<salesPersons>

如何修复

您需要将@XmlElementWrapper字段上的salesPersons注释更改为以下内容：

@XmlElementWrapper(name="SalesPersons")
@XmlElement(name="SalesPerson")
List<SalesPerson> salesPersons;

调试提示

当您遇到解组问题时，请填充对象模型，然后将其封送到XML。然后将此XML与您要解组的XML进行比较，以查看是否存在任何差异。

使用此XML

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<DealLookupResponse xmlns="http://www.starstandards.org/webservices/2005/10/transport" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:type="xsd:anyType">
    <Deal>
        <CompanyNumber>CN7</CompanyNumber>
        <DealNumber>111</DealNumber>
        <RecordStatus>A</RecordStatus>
        <SalesPersons>
            <SalesPerson>
                <RecordType/>
                <SalesPersonID>CL1</SalesPersonID>
                <Status>A</Status>
                <SaleDate>20140806</SaleDate>
                <SalesPersonName>CLOSER 1</SalesPersonName>
                <IncentiveCommission>0.00</IncentiveCommission>
                <TotalCommission>0.00</TotalCommission>
            </SalesPerson>
        </SalesPersons>
    </Deal>
