ajax @requestBody

前端：

$.ajax({
    type: "POST",contentType: "application/json;charset=UTF-8",url: REQUEST_URL.SAVE_ITEM_DETAILS,async: false,data: JSON.stringify(itemDetails.itemDetailList),//JSON对象需要转成JSON字符串
    success: function (retResult) {
        alert(retResult.retMsg);
    },error: function (XMLHttpRequest,textStatus,errorThrown) {
        alert("保存失败！");
    }
});

后台：

　　 @ResponseBody
    @RequestMapping("/saveItemDetails")
    public RetResult saveItemDetails(@RequestBody ItemDetail[] itemDetailList){ //ItemDetail中的属性不能少　　　　//todo save
    }
