为什么要用

@RequestBody   有些不用呢。 早就声明了号dao 层 或者entity 声明好了就不用。 否则要做后台解析

	@ResponseBody
	@RequestMapping(value = "searchDevice")
	public AjaxJson searchDevice(@RequestBody Serial serial,HttpServletRequest request){
        try {  
        	AjaxJson j = new AjaxJson();
        	String parm ="accessToken="+token+"&pageStart="+serial.getPageStart()+"&pageSize="+serial.getPageSize();
            String str = HttpURLConnectionUtil.HttpUrl(serial.getUrl(), parm);
            JSONObject jsonObject=JSONObject.fromObject(str);
            j.setObj(jsonObject);
            return j;
        
      
        } catch (Exception e) {  
            e.printStackTrace();  
        }
		return null;  
   
		
	}

	@ResponseBody
	@RequestMapping(value = "list")
	public AjaxJson list(Article article,HttpServletRequest request){
		AjaxJson j = new AjaxJson();	
		 List<Article> list = articleService.findListTreeData(article);
		 j.setList(list);
		return j;
	
		
	}
