Today uses @RequestBody comment

    @PutMapping("group")
    public int updateSpec(@RequestBody SpecGroup group) {
        System.out.println(group);
        int i = specificationService.updataSpe(group);
        return i;
    }

Because the front came through a json data, it is necessary to turn about. If you come through the front-end is also not resolved after the turn. For example stringify parsed into objects it is also possible.
So far we have been involved in the
@RequestParam
@PathVariable

@RestController
@RequestMapping
@ResponseBody
@Get/Post/PutMapping

These annotations, and serialization. The sequence of on and springify confused.
