后台控制层代码：

@GetMapping(value = {URI_FILE_CASE_PANEL_AUDI, URI_FILE_CASE_PANEL_AUDI_HTM})    public ModelAndView indexFile(@RequestParam(value = "caseId", required = false) Long caseId,                                  @RequestParam(value = "taskId", required = false) String taskId,                                  @RequestParam(value = "uuid", required = false) String uuid) {        LOGGER.info("enter file case audit panel,caseId:{},taskId:{}", caseId, taskId);        ModelMap map = new ModelMap();        map.put("caseId", caseId);        map.put("taskId", taskId);        map.put("uuid", uuid);        return new ModelAndView(FWD_FILE_CASE_PANEL_FILE_CASE, map);    }
