类装入器错误 - 未命名的模块的装入器 org.springframework.boot.devtools.restart.classloader.RestartClassLoader

我对Spring和Java作为一个整体很陌生，我目前正在研究一个API。我有这个代码访问MSSQL数据库，检索结果并应该可视化它，但它不起作用。我的意思是，如果我只调用过程并可视化结果集，它将正常工作。问题是我无法使用“RatingProcedure”对象。当我尝试获取某个对象的值时，它会向我显示以下错误：

Hibernate： {call dis_entity.spdcmpracovnici（?,?,?,?）} 2019-09-02 01：56：01.355 WARN 8720 --- [nio-8050-exec-3] .m.m.a.ExceptionHandlerExceptionResolver ： Resolved [java.lang.ClassCastException： class [Ljava.lang.Object; can not cast to class com.pproi.dcm.ratingprocedure.RatingProcedure.RatingProcedure.RatingProcedure （[Ljava.lang.Object; is in module java.base of loader 'bootstrap'; >com.pproi.dcm.ratingprocedure.RatingProcedure 位于 loader > 的未命名模块中org.springframework.boot.devtools.restart.classloader.RestartClassLoader @7193df92）]

代码：

@GetMapping("/replacements/{sourceId}/workers")
    public ResponseEntity<List<PossibleReplacementResponseModel>> getReplacements(@PathVariable Integer sourceId,
            @RequestParam(required = false) Integer targetWorkerId,
            @RequestParam(required = false) Integer targetLineId,
            @RequestParam(required = false) String targetWorkplaces) {

        List<PossibleReplacementResponseModel> response = new ArrayList<>();

        // 400 Bad Request
        if ((targetLineId != null && targetWorkerId != null) || (targetWorkplaces != null && targetLineId == null))
            return ResponseEntity.badRequest().build();

        StoredProcedureQuery ratingProcedure = entityManager.createNamedStoredProcedureQuery("dcmrating");

        StoredProcedureQuery storedProcedure = ratingProcedure.setParameter("pk_target_worker", targetWorkerId)
                .setParameter("pk_target_sdl", targetLineId).setParameter("pk_target_workplaces", targetWorkplaces)
                .setParameter("pk_source_sdl", sourceId);

        List<RatingProcedure> ratings = storedProcedure.getResultList();

        for(RatingProcedure rating : ratings) {
            PossibleReplacementResponseModel responseModel = new PossibleReplacementResponseModel();
            Optional<Worker> _worker = workerRepository.findById(rating.getPersonalId());

            if(_worker.isPresent()) {
                Worker worker = _worker.get();
                responseModel.setId(worker.getId());
                responseModel.setName(worker.getFullName());
                responseModel.setSkills(findWorkersSkills(worker));
                responseModel.setPhysicalExamination(findWorkersMedicalExaminationEndDate(worker));
                responseModel.setExams(findWorkersExams(worker));
                responseModel.setRestrictions(findWorkersRestrictions(worker));
                responseModel.setRating(rating.getRating());
            }
            response.add(responseModel);
        }

        return ResponseEntity.ok(response);
    }

我甚至可能对解决方案有一个想法！我可能应该自定义我的重新启动类加载器，如这里所示，但是我的技能在那里结束，我不知道我应该在文件中指定什么。

有什么想法吗？

非常感谢。
