前後端JSON傳值

後端接口實現

@RequestBody

    @PostMapping({"/question/choice/md5"})
    public ResponseEntity findExercises(@RequestBody @NotEmpty(message = "{exercises.id.NotEmpty.message}") List<String> cmd5s) {
        List<ChoiceQuestion> contentMd5s = service.findAllByContentMd5In(cmd5s);
        List<ChoiceRtnDto> repetitions = contentMd5s
                .stream()
                .map(e -> new ChoiceRtnDto(e.getContentMd5(), e.getTitle(), e.getPid()))
                .collect(Collectors.toList());
        return ResponseEntity.status(HttpStatus.ALREADY_REPORTED).body(repetitions);
    }
