系统是考试系统的改进版增加了了自动组卷功能 ，原来是将用的选的题目类型 /参数/难度拿到后台后，

生成随机数，从题库中随机获取题目。

实现的代码

@Autowired
    QuestionService questionService;
    /*自动生成试卷*/
    @RequestMapping(value = "/edit", method = RequestMethod.POST)
    public RestResponse<ExamPaperEditRequestVM> edit(@RequestBody Map map) {
        System.out.print(map);

        Integer difficulty = (Integer) map.get("difficulty");
        Integer multipleChoice = (Integer) map.get("multipleChoice");
        Integer shortAnswer = (Integer) map.get("shortAnswer");
        Integer trueFalse = (Integer) map.get("trueFalse");

        ExamPaperEditRequestVM model = new ExamPaperEditRequestVM();
        Instant instant = Instant.now();
        String timestamp = String.valueOf(instant.toEpochMilli());
        model.setLevel(1);
        model.setPaperType(1);
        model.setSubjectId(1);
        model.setName("自动生成试卷"+timestamp);
        model.setSuggestTime(30);
        model.setScore("100");

        ArrayList<ExamPaperTitleItemVM>  titleitems = new ArrayList<ExamPaperTitleItemVM>();


        ExamPaperTitleItemVM examPaperTitleItemVM = new ExamPaperTitleItemVM();

        examPaperTitleItemVM.setName("智能试卷"+timestamp );

        ArrayList<QuestionEditRequestVM> questionEditRequestVMS = new ArrayList<>();


        List<Question> page = questionMapper.page(new QuestionPageRequestVM());

        ArrayList<Integer> integers = new ArrayList<>();


        Random random = new Random();
        List<Integer> ids1 = page.stream()
                .filter(question -> question.getQuestionType() == 1) // 过滤指定类型的题目
                .filter(question -> question.getDifficult() == difficulty) // 过滤指定类型的题目
                .map(Question::getId) // 获取题目的ID
                .limit(multipleChoice)
                .collect(Collectors.toList());// 转换为列表


        List<Integer> ids3 = page.stream()
                .filter(question -> question.getQuestionType() == 3) // 过滤指定类型的题目
                .filter(question -> question.getDifficult() == difficulty) // 过滤指定类型的题目
                .map(Question::getId) // 获取题目的ID
                .distinct() // 去重
                .limit(shortAnswer)
                .collect(Collectors.toList());// 转换为列表


        List<Integer> ids5 = page.stream()
                .filter(question -> question.getQuestionType() == 5) // 过滤指定类型的题目
                .filter(question -> question.getDifficult() == difficulty) // 过滤指定类型的题目
                .map(Question::getId) // 获取题目的ID
                .distinct() // 去重
                .limit(trueFalse)
                .collect(Collectors.toList());// 转换为列表


        // 创建一个新的ArrayList用于合并
        List<Integer> mergedList = new ArrayList<>();
        mergedList.addAll(ids1);
        mergedList.addAll(ids3);
        mergedList.addAll(ids5);





        for (Integer id : mergedList) {
            QuestionEditRequestVM questionEditRequestVM = questionService.getQuestionEditRequestVM(id);
            questionEditRequestVMS.add(questionEditRequestVM);
        }

        examPaperTitleItemVM.setQuestionItems(questionEditRequestVMS);
        titleitems.add(examPaperTitleItemVM);

        model.setTitleItems(titleitems);

        ExamPaper examPaper = examPaperService.savePaperFromVM(model, getCurrentUser());
        ExamPaperEditRequestVM newVM = examPaperService.examPaperToVM(examPaper.getId());
        return RestResponse.ok(newVM);
    }
