导入实现
说明：首先根据条件查出的该类对应的集合，因为某些属性不需要，然后循环，并赋值给对应的单选、多选、判断集合

@PostMapping("/export")@RequiresPermissions("question:export")public void exportFile(@RequestBody Map<Object, Object> params, HttpServletResponse response) {Integer type = (Integer) params.get("quType");String content = (String) params.get("content");String panoramaId1 = (String) params.get("panoramaId");Integer level = (Integer) params.get("level");Long panoramaId = null;if
