Question

当我运行JAXBxmlToJava时，LocationType设置为null。任何人都可以建议如何将xml的类型组件映射到Java的LocationType对象。我有以下arc-response.xml： -

<address_component>
   <long_name>BMC Colony</long_name>
   <short_name>BMC Colony</short_name>
   <type>neighborhood</type>
   <type>political</type>
  </address_component>

以下代码，AddressComponent： -

@XmlRootElement(name = "address_component")
public class AddressComponent {

    @XmlElement(name = "long_name")
    private String longName;
    @XmlElement(name = "short_name")
    private String shortName;
    @XmlElement(name = "type")
    private Set<LocationType> locationTypeSet;
    //Setter Getter
}

的locationType： -

@XmlRootElement(name="type")
public class LocationType {

    private Integer locationTypeId;
    @XmlElement(name = "type")
    private String type;
    private String status;
    //Setter Getter
}

JAXBxmlToJava.java:-

    public class JAXBxmlToJava {
    public static void main(String[] args) {
        try {
            File file = new File("arc-response.xml");
            JAXBContext jaxbContext = JAXBContext.newInstance(AddressComponent.class);

            Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
            AddressComponent geoResponse = (AddressComponent) jaxbUnmarshaller.unmarshal(file);
            System.out.println(geoResponse);
        } catch (JAXBException e) {
            e.printStackTrace();
        }
    }
}

您需要@XmlValue将文本节点（例如“邻居”）映射到自定义类中的字段。

当我测试您的代码时，Set<LocationType>不是null - 其中有两个LocationType，但他们的 type字段是 null。我不确定这是否就是你在问题中的意思。

当我将LocationType课程更改为

时

@XmlRootElement(name = "type")
public class LocationType {

    private Integer locationTypeId;
    @XmlValue
    private String type;
    private String status;
    // Setter Getter
}

它有效。

将Java对象映射到@XmlElement值
