    Mcq_Question updateQuestion(@RequestBody Mcq_Question q)

    @GetMapping("/Questions/{question_id}")

    Mcq_Question getQuestion(@RequestParam(name="question_id") String id)
    {
        return qs.getQuestion(Integer.parseInt(id));
    }

    @GetMapping("/Questions")

    List<Mcq_Question> getQuestions()
    {
        
        return qs.getQuestions();
    }

    @RequestMapping(name="/Questions/{question_id}",method = RequestMethod.DELETE) 

    ResponseEntity<HttpStatus>  deleteQuestion(@RequestParam(name = "question_id",required =false) String id)
    {
        try {
            l.info(""+id);
    qs.deleteQuestion(Integer.parseInt(id));    
    l.debug(""+id);

        return new ResponseEntity<>(HttpStatus.OK);
        }catch (Exception e) {
            l.debug("jay  ijfiji"+e);

        return new ResponseEntity<>(HttpStatus.INTERNAL_SERVER_ERROR);
            }   
          }
    }

在客户端，我使用postman来访问api

方法 删除映射

http://localhost:8080/Questions?question_id=78

感谢大家的帮助我发现问题出在我的数据库上我尝试了手动删除数据，但表中存在一些不允许删除数据的限制“org.springframework.web.HttpRequestMethodNotSupportedException:请求方法'DELETE'不受支持\r\n\t请改用@DeleteMapping\r\n\t谢谢您的回复，但我使用了删除映射代码我尝试过@DeleteMapping，但仍然出现相同的错误
