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

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

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) {

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

debug看看其他层哪里有问题,这里贴上的代码应该没问题

qq_42200843
qq_42200843 我这controller层都没有进来,输入网址后回车直接就抛这个异常。
大约一年之前 回复

BeanInstantiationException,说明是初始化bean失败,检查有配置bean的类,比如xml或者@Service @Repository的类有没有写错,报没找到构造函数,有个类是私有构造函数?或者把接口初始化成Bean了?

图片说明
我终于找到原因了 看,试图找到参数的构造器,失败了没有找到,因为数组是找不到构造器的(并不是Object的原因)
我的天我跟了二十分钟才找到这里!!!
