Question

问题控制器

    import com.jay.login.entitie.Mcq_Question;
    import com.jay.login.service.QuestionService;

    @RestController

    public class QuestionController {

        @Autowired

        QuestionService qs;

        private static final Logger l=  LoggerFactory.getLogger(QuestionController.class);

        @PostMapping("/Questions")
       
         Mcq_Question addQuestion(@RequestBody Mcq_Question q)
        { System.out.println(q);
          return    qs.addQuestion(q);
        
         }
    @PutMapping("/Questions")

    Mcq_Question updateQuestion(@RequestBody Mcq_Question q)
    {
        return qs.updateQuestion(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);
            }   
          }
    }

错误如下：

感谢大家的帮助，我发现问题出在我的数据库上，我尝试手动删除数据，但表中有一些限制不允许删除数据
