How do I read attributes using jaxb?

Question

Given this XML:

<response>
    <detail Id="123" Length="10" Width="20" Height="30" />
</response>

This is what I have now, but it is not working (I'm getting empty result):

@XmlRootElement(name="response")
public class MyResponse {
    List<ResponseDetail> response;
    //+getters +setters +constructor
}

public class MyResponseDetail {
    Integer Id;
    Integer Length;
    Integer Width;
    Integer Height;
    //+getters +setters
}

I'm making a call to a remote service using RestOperations and I want to parse the <detail ..> element. I've tried passing both MyResponse and MyResponseDetail classes to RestOperations but the result is always empty.

What should my object structure look like to match that XML?

You need to annotate your classes like that:

@XmlRootElement
public class Response {

    private List<Detail> detail;

    public void setDetail(List<Detail> detail) {
        this.detail = detail;
    }
    public List<Detail> getDetail() {
        return detail;
    }

}

public class Detail {

    private String id;
    /* add other attributes here */

    @XmlAttribute(name = "Id")
    public void setId(String id) {
        this.id = id;
    }
    public String getId() {
        return id;
    }

}

+1 - Edited your answer to fix the accessors on the `Response` class, and remove unnecessary annotations. – bdoughan Aug 14 '13 at 13:48
