[Ljava.lang.Object;]: No default constructor found

Question

Servlet.service() for servlet [springmvc] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate **[[Ljava.lang.Object;]: No default constructor found; **nested exception is java.lang.NoSuchMethodException: [Ljava.lang.Object;.()] with root cause
java.lang.NoSuchMethodException: [Ljava.lang.Object;.()

我在做一个网站开发，我希望在Cotroller层中传入Object类型的可变参数，就一直报这个错误，请问该怎么解决呢？以下是我的代码：

//可变参数做查询
    //localhost/detailsss/?detail=徐国权&detail=12
    @RequestMapping("/detailsss/")
    public String queryDetails(Model model,Object...detail){

        try {
            Object consume = null;
            List<Object> list = new ArrayList<>();
            for(Object obj : detail){   
                if(obj instanceof String){                  
                    consume = new String(((String) obj).getBytes("iso-8859-1"),"utf-8");
                }
                else if(obj instanceof Integer){
                    consume = (int)obj;
                }
                else if(obj instanceof Date){
                    consume = (Date)obj;
                }
                else if(obj instanceof Time){
                    consume = (Time)obj;
                }else{
                    consume = obj;
                }
                list.add(consume);
            }
            //调用service的方法
            List<Detailed> details = comsumeService.queryDetails(list);
            model.addAttribute("details",details);
            return "comsume_info";
        } catch (Exception e) {
            e.printStackTrace();
            return "err";
        }       
    }

Object类不能直接实例化，直接用string类型呗，跟object不是一样嘛
