Spring Rest Controller @PostMapping parameter best practice ？

一般 postmapping 接收 json 数据的时候用什么格式比较好呢？ DTO object 还是 map ？

以下两个例子对比一下你觉得哪个好呢？

1. Map：

    @PostMapping("")
    public ResponseEntity<Transaction> addTransaction(HttpServletRequest request,
                                                      @PathVariable("categoryId") Integer categoryId,
                                                      @RequestBody Map<String, Object> transactionMap) {

1. DTO object：

    @PostMapping(path = "/", consumes = "application/json", produces = "application/json")
    public ApiResultBean createOrUpdatePeople(@Valid @RequestBody PostPeopleDTO postPeopleDTO) throws JsonProcessingException {
