I am working on a spring mvc application. I needed an async request, so I came across a request which returns Callable

TestController.java


@RequestMapping(value ="/views/async", method = RequestMethod.GET)
public Callable<String> getViewAsyncWay(){
    return new Callable<String>(){
        Thread.sleep(5000);
        return "test-async"
    };
}

test-async.jsp


    <div>This page is delivered with async request.</div>

home.jsp


    $(document).ready(function(){
        $('btn-aync-req').on('click', function(){
            $.ajax({
                type: 'GET',
                url: "<c:url value="/views/async"/>",
                success: function(data){
                    $('#container').html(data);
                }
            });
        });
    });

    <body>
        <div id="container">
        </div>
        <input type="button" id="btn-async-req" value="Send Request"/>
    </body>

Now when I click on the Send Request, server log says request processed normally and the resource returned is /views/aysnc.jsp (which is my request uri)

I am not able to figure out which step I am making mistake.

To applicationContext.xml I have added:


<task:annotation-driven/>

The normal spring-mvc request in my project works fine.
