How should I access a Spring MVC rest service using javascript?

Question

I have a Spring-MVC based rest service returning json which is setup like so

@Controller
@RequestMapping("/api")
public class JSONController {

@Autowired
private FooService fooService;

@RequestMapping(value = "{name}", method = RequestMethod.GET)
public @ResponseBody
List<Foo> getFoos(@PathVariable String name)

I plan on doing the rest of the CRUD operations through this api - what I was wondering was how should I write a client - using Json or JsonP?

At the moment I've retrieved the list of Foos with

    $.ajax({
    type: "GET",
    dataType: "jsonp",
    url: "http://xxx.com/rest/api/1",
    success: function(data){
        alert(data);
        $.each(data, function(index, data) {

            var foo = $.extend(new Foo(result[key].name));
            users.push(foo );

        });

    }
});

I can see the returned objects in firebug but the success callback is not reached. Is there a proper client side pattern for interacting with restful services?

Cheers!

It seems that your call is not reaching the success function because you are returning the list of you call in jsonp format. The mapper i think JacksonMapper is returning the list in "json" format.

If you use:

$.ajax({
    type: "GET",
    dataType: "json",
    url: "http://xxx.com/rest/api/1",
    success: function(data){
        alert(data);
        $.each(data, function(index, data) {

            var foo = $.extend(new Foo(result[key].name));
            users.push(foo );

        });

    }
});

It should work, I hope it helps.

Thanks for your response. I found the answer I needed in a few blogs by adding CORS support to the backend request. Here's some more info java-success.blogspot.com.au/2012/11/…
