ajax 发送post请求传参给SpringMVC

function addNewPrice() {
		
			var data = {};
			data.revitAddInId = $("#revitAddInId").val();
			data.period = $(".periodSelector").val();
			data.money = $("#money").val();
			if (data.money.length==0 || isNaN(data.money)){
				alert("钱不能为空,且要为数字");
				return false;
			}
			data.srevitAddInName = $(this).data("name");
			//datas.push(data);
			//console.log(JSON.stringify(datas));
			$.ajax({
				url : ctx + '/revitAddIn/addPrice.html',
				type : "POST",
				contentType : "application/json",
				data : JSON.stringify(data),
				dataType : 'json',
				success : function(data) {
					if (data.success) {
						location.href =ctx+ "/XX/enterPriceEdit.html?reivtAddInId="+$("#revitAddInId").val()+
								"&revitAddInName="+$("#revitAddInName").val();
					}
				}
			}); 

后端使用requestbody 对象接收
