Question

Using $.getJSON my result can be empty, a single value or a list of values.

If the result contains a single value i can access the data via result.someReturnedValue however if the result contains a list i have to loop through the result data using array syntax to access the data E.g. result[i].someReturnedValue

Now i dont want to write the same code twice to handle each type of result. (I’m appending the result to DOM elements and the code is getting large when i have to account for both notations) Is there a generic way i can handle the result to prevent this duplication?

Example of single result;

    $('div[id="'+divId+'"]').append("<td>" + result.someValue1+ "</td>");
$('div[id="'+divId+'"]').append("<td>" + result.someValue2+ "</td>");
$('div[id="'+divId+'"]').append("<td>" + result.someValue2+ "</td>");

Example of multiple results:

    $('div[id="'+divId+'"]').append("<td>" + result[i].someValue1+ "</td>");
$('div[id="'+divId+'"]').append("<td>" + result[i].someValue2+ "</td>");
$('div[id="'+divId+'"]').append("<td>" + result[i].someValue2+ "</td>");

Ok i found a solution for this issue. You can create your own Provider class which Jersey will use when generating the JSON response.

@Component
@Provider
public class 

JAXBContextResolver implements ContextResolver<JAXBContext> {

private final JAXBContext context;

private final Class[] cTypes = { SomeCustomClass.class };

public JAXBContextResolver() throws JAXBException {
    this.context = new JSONJAXBContext(JSONConfiguration.natural().build(),
            cTypes);
}

public JAXBContext getContext(Class<?> objectType) {
    for (Class type : cTypes) {
        if (type == objectType) {
            return context;
        }
    }
    return null;
}

This provider uses the NATURAL JSON notation, which serializes the object as required in list format.

Ensure Spring is aware of the class by including the necessary annotations/bean definition
