Controller?

package club.zstuca.myzstu.controller;import club.zstuca.myzstu.dto.yooc.ExamDTO; import club.zstuca.myzstu.dto.yooc.QuestionDTO; import club.zstuca.myzstu.entity.yooc.Question; import club.zstuca.myzstu.service.IYOOCExamQuestionService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.*;import javax.servlet.http.HttpServletResponse; import java.util.ArrayList; import java.util.List;/*** @Author ShenTuZhiGang* @Version 1.0.0* @Date 2020-04-26 08:26*/ @Controller @CrossOrigin @RequestMapping("/yooc") public class YOOCController {@AutowiredIYOOCExamQuestionService iyoocExamQuestionService;@ResponseBody@RequestMapping(value = "/group/{groupId}/exam/{examId}/upload",method = RequestMethod.POST)public Object uploadExam(@PathVariable("groupId")String groupId,@PathVariable("examId")String examId,@RequestBody List<QuestionDTO> questionDTOS,HttpServletResponse response){response.setHeader("Content-Security-Policy","upgrade-insecure-requests");List<Question> questions = new ArrayList<>();for (QuestionDTO questionDTO: questionDTOS) {Question question =new Question(groupId,examId,questionDTO.getId().substring(9),questionDTO.getQuestion());questions.add(question);//System.out.println(question);}iyoocExamQuestionService.saveOrUpdateBatch(questions);return questions;}@ResponseBody@RequestMapping(value = "/group/{groupId}/exam/{examId}/answer",method = RequestMethod.GET)public Object getAnswerByQuestionId(@PathVariable("groupId")String groupId,@PathVariable("examId")String examId,@RequestParam("question") List<String> questions){List<QuestionDTO> questionDTOS = new ArrayList<>();for (String question:questions) {Question questiona=iyoocExamQuestionService.getById(question);if(questiona==null){questionDTOS.add(QuestionDTO.getNullQuestionDTO(question));}else{questionDTOS.add(new QuestionDTO(questiona.getId(),questiona.getQuestion()));}}return questionDTOS;} }

無答案時

public static QuestionDTO getNullQuestionDTO(String id){QuestionDTO question = new QuestionDTO();question.setId(id);question.setQuestion("<div class=\"question-board\" id=\"question-"+id+"\">\n" +" <div class=\"the-ans fls\">\n" +" <p>這一題還沒有正確的答案，快點上傳吧！</p>\n" +" </div>\n" +" </div>");return question;}
