Question

I have a REST api GET call that takes an array of strings formatted as JSON. I’d like to use Jersey to convert that array of strings to something like a string array or List. I’ve reviewed http://jersey.java.net/nonav/documentation/latest/json.html, but it looks like Jersey wants me to create an object that specifies how it should be mapped, which I really don’t want to do because it’s just a simple array.

        @GET
        public Response get(@QueryParam("json_items") String requestedItems) throws IOException
        {
            //Would like to convert requestedItems to an array of strings or list

        }

I know there are lots of libraries for this – but I’d prefer to use Jersey and not introduce any new libraries.

Answer 1

Just try to add to your Response the array, like

return Response.ok(myArray).build();

and see what happen.
If it’s just a very simple array it should be parsed without any problem.

EDIT:

If you want to receive it then just accept an array instead of a String. Try with a List or something like this.

Otherwise you can try to parse it using an ObjectMapper

mapper.readValue(string, List.class);
