HttpClient通過Post方式發送Json數據

服務器用的是Springmvc，接口內容：

?

@ResponseBody??
@RequestMapping(value="/order",method=RequestMethod.POST)??
public?boolean?order(HttpServletRequest?request,@RequestBody?List<Order>?orders)?throws?Exception?{??
????AdmPost?admPost?=?SessionUtil.getCurrentAdmPost(request);??
????if(admPost?==?null){??
????????throw?new?RuntimeException("[OrderController-saveOrUpdate()]?當前登陸的用戶職務信息不能為空！");??
????}??
????try?{??
????????this.orderService.saveOrderList(orders,admPost);??
????????Loggers.log("訂單管理",admPost.getId(),"導入",new?Date(),"導入訂單成功,訂單信息-->?"?+?GsonUtil.toString(orders,?new?TypeToken<List<Order>>()?{}.getType()));??
????????return?true;??
????}?catch?(Exception?e)?{??
????????e.printStackTrace();??
????????Loggers.log("訂單管理",admPost.getId(),"導入",new?Date(),"導入訂單失敗,訂單信息-->?"?+?GsonUtil.toString(orders,?new?TypeToken<List<Order>>()?{}.getType()));??
????????return?false;??
????}??
}??

通過ajax訪問的時候，代碼如下：

?

?

??????????????????$.ajax({??
????type?:?"POST",??
????contentType?:?"application/json;?charset=utf-8",??
????url?:?ctx?+?"order/saveOrUpdate",??
????dataType?:?"json",??
????anysc?:?false,??
????data?:?{orders:[{orderId:"11",createTimeOrder:"2015-08-11"}]},??//?Post?方式，data參數不能為空""，如果不傳參數，也要寫成"{}"，否則contentType將不能附加在Request?Headers中。??
????success?:?function(data){??
????????if?(data?!=?undefined?&&?$.parseJSON(data)?==?true){??
????????????$.messager.show({??
????????????????title:'提示信息',??
????????????????msg:'保存成功！',??
????????????????timeout:5000,??
????????????????showType:'slide'??
????????????});??
????????}else{??
????????????$.messager.alert('提示信息','保存失敗!','error');??
????????}??
????},??
????error?:?function(XMLHttpRequest,?textStatus,?errorThrown)?{??
????????alert(errorThrown?+?':'?+?textStatus);?//?錯誤處理??
????}??
});??

通過HttpClient方式訪問，代碼如下：
