xml with attributes to java object with jaxb

Question

I have an xml like below:

<response>
    <adminArea5 type="City">Rochester</adminArea5>
    <adminArea3 type="State">NY</adminArea3>
    <adminArea4 type="County">Monroe County</adminArea4>             
    <adminArea1 type="Country">US</adminArea1>
</response>

Java Class:

public class Response{

    private String street;

    @XmlAttribute(name = "adminArea5")
    private String city;

    @XmlAttribute(name = "adminArea3")
    private String state;

    @XmlAttribute(name = "adminArea4")
    private String county;

    @XmlAttribute(name = "adminArea1")
    private String country;
}

I am using "JAXB.unmarshal(new StringReader(xml), targetClass)" to parse xml into java object. But these fields are being null after parsing xml. Any help will be appreciated.

create an XML file in the project, right click on the XML file and generate a schema and then generate the java classes. [Generate Java Classes from XML](https://stackoverflow.com/questions/24982321/jaxb-unmarshalling-issues-with-xml-attributes) — lucas, May 06 '20 at 17:50

Update your Java class as below

@XmlRootElement(name = "response")
@XmlAccessorType(XmlAccessType.PROPERTY)
public class Response {
    private String street;

    @XmlElement(name = "adminArea5")
    private String city;

    @XmlElement(name = "adminArea3")
    private String state;

    @XmlElement(name = "adminArea4")
    private String county;

    @XmlElement(name = "adminArea1")
    private String country;

    @Override
    public String toString() {
        return "Response{" +
                "street='" + street + '\'' +
                ", city='" + city + '\'' +
                ", state='" + state + '\'' +
                ", county='" + county + '\'' +
                ", country='" + country + '\'' +
                '}';
    }
}
