Question

我有一个xml文件：

@XmlRootElement(name = "Data", namespace = "http://vv.com/namespace")
public class AddressDto implements Serializable
{
    private String street;
    private String city;
    private CountryDto country;

    public AddressDto()
    {
        super();
    }
    
    @XmlElement(name = "Addr")
    public String getStreet1()
    {
        return street;
    }

    public void setStreet1(final String street1)
    {
        this.street = street1;
    }

    @XmlElement(name = "Locality")
    public String getCity()
    {
        return city;
    }

    public void setCity(final String city)
    {
        this.city = city;
    }

    public CountryDto getCountry()
    {
        return country;
    }
    
    public void setCountry(final CountryDto country)
    {
        this.country = country;
    }
}

AddressDto.java

public class CountryDto implements Serializable
{
    private String name;
    private String code;

    public CountryDto()
    {
        super();
    }

    @XmlElement(name = "CountryCode")
    public String getCode()
    {
        return code;
    }

    public void setCode(final String code)
    {
        this.code = code;
    }
    
    @XmlElement(name = "Country")
    public String getName()
    {
        return name;
    }

    public void setName(final String name)
    {
        this.name = name;
    }
}

CountryDto档案：

JAXBContext context = JAXBContext.newInstance(AddressDto.class);
Unmarshaller un = context.createUnmarshaller();
AddressDto emp = (AddressDto) un.unmarshal(response.getSOAPBody().extractContentAsDocument());
return emp;

当我运行代码时

{{1}}

我可以在AddressDto对象中获取街道和城市。但是田野国家显示为空......任何想法在这里出错了吗？

谢谢

Parser不知道Country / CountryCode的含义。您在AddressDto类中仅将Addr和Locality定义为XmlElement。因此，您将获得null。

您需要将xml修改为以下内容：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <ns1:Data xmlns:ns1="http://vv.com/namespace">
         <Addr>Address 1</Addr1>
         <Locality>San Francisco</Locality>
         <CountryDto>
             <Country>Japan</Country>
             <CountryCode>JP</CountryCode>
         </CountryDto>
      </ns1:Data>
   </soapenv:Body>
</soapenv:Envelope>

并修改你的地址以便 getCountry（）也是XmlElement：

@XmlElement(name = "CountryDto")
public CountryDto getCountry()
{
    return country;
}

现在Country和CountryCode不再为null

无法解析另一个对象内的对象
