如何在客户端使用JAXB注释进行GWT？

import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlElement;

@XmlRootElement
public class Person {
    private String name;
    private int age;

    @XmlElement
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @XmlElement
    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

import com.google.gwt.http.client.RequestBuilder;
import com.google.gwt.http.client.RequestCallback;
import com.google.gwt.http.client.Response;
import com.google.gwt.http.client.RequestException;
import com.google.gwt.http.client.URL;

public class MyClient {
    public void fetchData() {
        RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, URL.encode("/api/person"));
        try {
            builder.sendRequest(null, new RequestCallback() {
                public void onResponseReceived(Request request, Response response) {
                    if (response.getStatusCode() == 200) {
                        Person person = JAXB.unmarshal(response.getText(), Person.class);
                        // 处理获取到的数据
                    } else {
                        // 处理错误情况
                    }
                }

                public void onError(Request request, Throwable exception) {
                    // 处理请求错误
                }
            });
        } catch (RequestException e) {
            // 处理请求异常
        }
    }
}
