Question

Using Jackson I can able to convert the object to JSON

@RequestMapping(value="getMessage.test", headers = "Accept=application/json" ,method = RequestMethod.POST)
    public @ResponseBody TestObject getMessage(){
        TestObject object=new TestObject();
        object.setMessage("Hello JQuery");
        return object;
    }

The above code works well… But conversion from JSON to Object gives WARN PageNotFound – No matching handler method found for servlet request: path ‘/setMessage.test’, method ‘POST’, parameters map[[empty]] Below is the code. Where i am going wrong..

@RequestMapping(value="setMessage.test", method = RequestMethod.POST, headers = "Accept=application/json"  )
    public void setMessage(@RequestBody TestObject test,HttpServletRequest request){
        System.out.println("Inside setting message");
        System.out.println(test.getMessage());
    }

JQuery Ajax calls…

 $.ajaxSetup({   contentType: "application/json; charset=UTF-8" }); 

    $.post('getMessage.test',function(response) {  
        alert(response.message);
           }, 'json');  

    $.post( 'setMessage.test', {message: 'Hello Spring'});

Finally i got the fix. There is a bug in JQuery $.post method which is not setting the proper contenttype. So setting the contenttyple in the ajaxsetup works well… and i used jquery.json-2.3.min.js to create a json object…..

$.ajaxSetup({   
           contentType: "application/json; charset=UTF-8"
    });
