XStream to use getter for serialization

Question

My web service returns data in both xml and json using Spring MVC. For json, spring uses Jackson and XStream for XML. However, XStream uses fields for serialization while Jackson uses methods (setter/getter).

I would like to include all/some getter in xml serialization. How can this be accomplished via a custom converter or annotation?

You need to register a custom JavaBeanConverter, take a look at the unit tests here: https://fisheye.codehaus.org/browse/xstream/tags/XSTREAM_1_1_3/xstream/src/test/com/thoughtworks/xstream/converters/javabean/JavaBeanConverterTest.java?r=554

XStream xstream = new XStream();
xstream.registerConverter(new JavaBeanConverter(xstream.getClassMapper(), "class"), -20);

If you make the fields public, Jackson can use them instead of getter/setter methods. There is also an annotation @JsonProperty to cause that.

public class KeyValuePair {

    @JsonProperty
    private int value;
    @JsonProperty
    private String key;
}

Or look here how to specify jackson to only use fields - preferably globally to understand:

 @JsonAutoDetect(fieldVisibility = Visibility.ANY, getterVisibility = Visibility.NONE, setterVisibility = Visibility.NONE)

Thanks, would you be able to tell me which annotation? I been searching for it and couldn't find anything. – ltfishie Feb 22 '13 at 19:20
I was looking for the XStream XML annotation. Sorry if the question wasn't clear. – ltfishie Feb 22 '13 at 19:32
