将XML属性映射到Java属性

Question

Is there a way to map xml attributes to Java attributes using Jackson Faster xml.
Sample xml
<student>
 <details>
  <element key="firstName" value="John" />
  <element key="lastName" value="Doe" />
 </details>
</student>

以上XML需要映射到Java类以下。

public class Student {
private String firstName;
private String lastName;
}

Answer 1

对于这种情况，我编写了静态代码：

public static <T> T unmarshall(String xml, Class<T> clazz) throws JAXBException {
        JAXBContext jc = JAXBContext.newInstance(clazz);
        Unmarshaller unmarshaller = jc.createUnmarshaller();
        T obj = clazz.cast(unmarshaller.unmarshal(new StringReader(xml)));
        return obj;
    }

也注释您的DTO：

@Getter
@Setter
@XmlRootElement(name = "<SomeName>")
@XmlAccessorType(XmlAccessType.FIELD)
public class Student {
private String firstName;
private String lastName;
}

使用此方法后，您可以使用它来序列化数据：

Student studentResponse = (Student) unmarshall(response, Student.class);
