针对于get请求 springmvc前端传对象后端接收后进行取值并对数据库进行操作

controller层代码

 @RequestMapping(value = "/deleteone",method = RequestMethod.GET,produces = {"application/json;charset=UTF-8"})
    public Result deleteone(@RequestParam(name = "checkitem") String checkItem){
        try {
            //解决get乱码问题
            String str=new String(checkItem.getBytes("ISO8859-1"),"UTF-8");
            //将字符串转换成对象
            CheckItem checkItem1 = new Gson().fromJson(str, CheckItem.class);
            Integer id = checkItem1.getId();
            System.out.println(id);
            checkItemService.deleteone(id);
            return new Result(true, MessageConstant.DELETE_CHECKITEM_SUCCESS,null);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return new Result(false, MessageConstant.DELETE_CHECKITEM_FAIL,null);
    }

前端js：

  handleDelete(row) {
                    this.resetForm();
                    //发送ajax请求
                    var _this = this;
                    //param由后端QueryPageBean queryPageBean接收请求映射参数
                    console.log(row)
                    axios.get("/checkitem/deleteone.do", {params:{checkitem:row}},
                    ).then((resp) => {
                        console.log(resp.data)
                        if(resp.data.flag){ // 服务器端处理成功
                            _this.$message({
                                message: resp.data.message,
                                type: 'success'
                            });
                            _this.findPage();
                        }else{ // 服务器端处理失败
                            _this.$message.error(resp.data.message);
                        }
                    });

尝试过后端直接用对象接收数据发现接收的全是null？

此问题有待解决！上面的方法只是没办法的情况下的办法
