Java/JAXB: Unmarshall XML elements with same name but different attribute values to different class members

问题

I am trying to parse XML that has several "Fields" elements to different class members according to one of their attributes. Here is the XML:

<Series>
    <Fields type="SelectedFields" operation="SUM">
        <Field name="Remaining" />
        <Field name="Invested" />
    </Field>
    <Fields type="FirstSelectedFields" operation="SUM">
        <Field name="Estimated" />
    </Field>
</Series>

And here is the java class it should be mapped to:

public class APMSeries {

    private List<Field> selectedFields;

    private List<Field> firstSelectedFields;

}

Can anyone tell me how can I set the Fields element with attribute type="SelectedFields" to the selectedFields member and the Fields element with the attribute type="FirstSelectedFields" to the firstSelectedFields member?

回答1:

public class APMSeries {

    @XmlElementWrapper(name="SelectedFields")
    private List<Field> selectedFields;

    @XmlElementWrapper(name="FirstSelectedFields")
    private List<Field> firstSelectedFields;

}
