调用接口 ,返回arraylist的时候出现这个错误,一开始还在排查是否是不能返回arraylist,因为list我一直用,是可行的。按道理实现的接口都是list没问题
最后发现问题。。。
arraylist< Object > 中的Object实体类没写 getter and setter方法。。

下面是查过以后可能会遇到的方法

@PostMapping("/getListByIdPost")
    @ResponseBody
    @JsonBackReference
    public JSONArray getListByIdPost(int id){
     
        System.out.println(tabOrganizationsService.listOrganizationsById(id));
        List<TabOrganizations> test = tabOrganizationsService.listOrganizationsById(id);
        return (JSONArray) JSON.toJSON( tabOrganizationsService.listOrganizationsById(id));
    }
