500内部服务器错误

Question

当我尝试在我的RESTful webservice中测试方法时，我得到500：内部服务器错误。我已将方法从返回ModelAndView转换为返回ResponseEntity。

我的代码：

旧代码

@RequestMapping("showAdd")
    @PreAuthorize(AUDIT_MANAGE_PERM_EXPR)
    public ModelAndView showAdd(@RequestParam("id") Long id, @RequestParam("type") String type) {
        return setModel(id, false, type);
    }

private ModelAndView setModel(Long id, Boolean view, String type) {
        ScheduleAuditElement scheduleAuditElement = elementService.findByAll(id);
        List<ElementDataGridHelper> elementDataGridHelpers = resultService.getElementsData(scheduleAuditElement);
        ModelAndView mv = new ModelAndView(ADD_PAGE);
        mv.addObject("type", type);
        ElementResult elementResult = null;
        if (!resultService.isHierarchy(scheduleAuditElement.getElement().getId())
                && scheduleAuditElement.getStatus().equals(STATUS_ASSIGNED))
            mv.addObject("isHierarchy", false);
        else
            mv.addObject("isHierarchy", true);

        mv.addObject(ATTR_ELEMENT_DATA_HELPERS, elementDataGridHelpers);

        if (scheduleAuditElement.getStatus().equals(STATUS_ASSIGNED)) {
            elementResult = new ElementResult();
            elementResult.setScheduleAuditElement(scheduleAuditElement);
            mv.addObject("isNew", true);
        } else {
            elementResult = resultService.findBySchedule(scheduleAuditElement.getId());
            mv.addObject("isNew", false);
        }
        mv.addObject("elementResult", elementResult);
        mv.addObject("isView", view);
        mv.addObject("scheduleAuditId", scheduleAuditElement.getScheduleAudit().getId());
        mv.addObject("isSubmit", true);

        if (type.equals("view"))
            mv.addObject("screenId", helpService.findScreenId("2115"));
        else
            mv.addObject("screenId", helpService.findScreenId("2113"));
        return mv;
    }

新代码

@RequestMapping(value="showAdd",method=RequestMethod.GET)
    public ResponseEntity<Map<String, Object>> showAdd(@RequestParam("id") Long id, @RequestParam("type") String type){
        Map<String, Object> mapShowAdd = new HashMap<>();
    //  ResponseEntity<Map<String, Object>> resp = new ResponseEntity<Map<String,Object>>((Map<String, Object>) mapShowAdd, HttpStatus.OK);
        //resp=setModel(id, false, type);
        mapShowAdd.put("Set Model", setModel(id, false, type));
        return new ResponseEntity<Map<String, Object>>(mapShowAdd, HttpStatus.OK);
    }

则setModel

private ResponseEntity<Map<String, Object>> setModel(Long id, Boolean view, String type){
        ScheduleAuditElement scheduleAuditElement = elementService.findByAll(id);
        List<ElementDataGridHelper> elementDataGridHelpers = resultService.getElementsData(scheduleAuditElement);
        Map<String, Object> mapSet = new HashMap<>();
        mapSet.put("type", type);
        ElementResult elementResult = null;
        if (!resultService.isHierarchy(scheduleAuditElement.getElement().getId())
                && scheduleAuditElement.getStatus().equals(STATUS_ASSIGNED))
            mapSet.put("isHierarchy", false);
        else
            mapSet.put("isHierarchy", true);

        mapSet.put(ATTR_ELEMENT_DATA_HELPERS, elementDataGridHelpers);
        if (scheduleAuditElement.getStatus().equals(STATUS_ASSIGNED)) {
            elementResult = new ElementResult();
            elementResult.setScheduleAuditElement(scheduleAuditElement);
            mapSet.put("isNew", true);
        } else {
            elementResult = resultService.findBySchedule(scheduleAuditElement.getId());
            mapSet.put("isNew", false);
        }

        mapSet.put("elementResult", elementResult);
        mapSet.put("isView", view);
        mapSet.put("scheduleAuditId", scheduleAuditElement.getScheduleAudit().getId());
        mapSet.put("isSubmit", true);

        if (type.equals("view"))
            mapSet.put("screenId", helpService.findScreenId("2115"));
        else
            mapSet.put("screenId", helpService.findScreenId("2113"));
        return new ResponseEntity<Map<String, Object>>(mapSet, HttpStatus.OK);

    }
