SSM处理前端ajax发送json数组对象转List

前端ajax请求

var datalist = new Array();var object = new Object();datalist.push(object);$.ajax({            type : "POST",            url : "select/saveOffer",            // async : false,            data : JSON.stringify({                "datalist" : datalist,                "selectLE" : selectLE,                "usercode" : usercode,                "no" : no,                "offersys" : offersys            }),            dataType : "json",            contentType : "application/json; charset=utf-8",            success : function(data) {}

后台接收处理请求

@RequestMapping(value = "/saveOffer", method = RequestMethod.POST)    // @Token(save = true)String arr = com.alibaba.fastjson.JSONArray.toJSONString(map.get("datalist"));                List<OfferValues> datalist = new ArrayList<>();                datalist = com.alibaba.fastjson.JSONArray.parseArray(arr, OfferValues.class);    }
