后台接收json对象

需求：后台接收json对象

js代码如下：

function ss(){
	var sss = JSON.stringify({"datas":[{"name":"小红", "password":"12231123"}，{"name":"小黑s", "password":"12231123"}],
              "data":{"orderNumber":"123222", "name":"三星"}});
	$.ajax({        
		type:'post',        
		url: path+'/RoadTestController/saveRoadTest.do',  
		dataType:'json',  
		async: true,
		data: {"date":sss},
		success:function(result){
			
		}
			
	});
}

controller代码如下：

 */
	@RequestMapping("saveRoadTest")
	public ModelAndView saveRoadTest(HttpServletRequest request,HttpServletResponse response){
		String jsonStr = request.getParameter("date");
		JSONObject RoadTest = JSONObject.fromObject(jsonStr).getJSONObject("data");
		JSONArray RoadTestDetails = JSONObject.fromObject(jsonStr).getJSONArray("datas");
		int result = 0;
		String msg = "";
		if(RoadTestDetails.size()!=0){
			List<RoadTestDetails> detailsList = new ArrayList<RoadTestDetails>();
			for(int i=0;i<RoadTestDetails.size(); i++){
				JSONObject jsonJ = RoadTestDetails.getJSONObject(i);
				RoadTestDetails rtd= new RoadTestDetails();
				rtd.setName(jsonJ.getInt("name"));
				rtd.setPassword(jsonJ.getString("password"));
			}
			boolean istrue = appService.insertRoadTestDetails(detailsList);
			if(istrue){
				result = 1;
				if(RoadTest.size()!=0){
					List<RoadTest> list = new ArrayList<RoadTest>();
					RoadTest rt = new RoadTest();
					rt.setOrderNumber(RoadTest.getString("orderNumber"));
					rt.setName(RoadTest.getString("name"));
					boolean isTrue = appService.insertRoadTest(list);
					if(isTrue){
						 result = 1;
					}else{
						 result = 0;
						 msg = "上传数据失败！";
					}
				}
			}else{
				msg = "上传数据失败！";
			}
		}else{
			msg = "上传数据为空！";
		}
		MappingJackson2JsonView view = new MappingJackson2JsonView();
		Map<String, Object> attributes = new HashMap<String, Object>();
		attributes.put("result", result);
		attributes.put("message", msg);
		view.setAttributesMap(attributes);
		ModelAndView model = new ModelAndView();
		model.setView(view);
		return model;
	}
