This is my controller :

@Controller
@RequestMapping(value = "/paymentgateway")
public class PaymentGatewayController {


@RequestMapping(value = "/checkPayStatusProposalID/{proposalID}", method = RequestMethod.GET)
@ResponseBody
public PGTransaction checkPayStatusByProposalId(@PathVariable String proposalID) throws Exception {
		
PGTransaction pgTrans = commservice.fetchPaymetDetailsByProposalID(proposalID);
		
		return pgTrans;

	}
}

This is my ajax call by which i am trying to call my handler method in spring controller. 

function test(){
var testData = 	{"proposalID":"123"}	            
	var URL =  "http://localhost:8080/ABHI/paymentgateway/checkPayStatusProposalID/123";
$.ajax({
                url : URL,
                async :false,
                type : 'POST',
				
                dataType : 'json',
                data: JSON.stringify(testData),
                contentType : 'application/json',
                mimeType : 'application/json',
                crossDomain : true,
				
                success : function(data) {	
				console.log(JSON.stringify(data,null,4));
				alert(data);
                },
                error : function(data, status, er) {
				console.log(JSON.stringify(data,null,4));
                    console.log("Errors : ");  //+data.responseJSON.errorMessage
                }
            });
			}

Error that i am getting on chrome: 

jquery.js:4 Failed to load http://localhost:8080/myProject/login/fetchagent: Response to preflight request doesn't pass access control check: 
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

    "statusText": "NetworkError: Failed to execute 'send' on 'XMLHttpRequest':
