Swagger无法渲染 Finished Loading Resource Information. Rendering Swagger UI...

问题：无法渲染swagger ui页面，本来swagger页面是正常加载的，但突然不能加载了

 

 修改前代码：

 @ApiOperation(value = "新地图的告警", notes = "新地图的告警")
    @GetMapping("/getAlarmList")
    @MyLog(title = "地图配置管理-查询",action = "新地图的告警")
    public DataResult getListByECIds( Boolean dataRights, HttpServletRequest request, String type) {
        String accessToken=request.getHeader(BaseConstant.ACCESS_TOKEN);
        String userId = JwtTokenUtil.getUserId(accessToken);
        List<Map> list = null;
        try {
            list =  gisEntityGeometryService.getAlarmList(userId,dataRights,type);
        } catch (Exception e) {
            e.printStackTrace();
            return DataResult.getResult(400, "查询失败");
        }
        return DataResult.success(list);
    }

修改代码后：

 @ApiOperation(value = "新地图的告警", notes = "新地图的告警")
    @GetMapping("/getAlarmList")
    @MyLog(title = "地图配置管理-查询",action = "新地图的告警")
    public DataResult getListByECIds(@RequestParam("dataRights") Boolean dataRights, HttpServletRequest request, String type) {
        String accessToken=request.getHeader(BaseConstant.ACCESS_TOKEN);
        String userId = JwtTokenUtil.getUserId(accessToken);
        List<Map> list = null;
        try {
            list =  gisEntityGeometryService.getAlarmList(userId,dataRights,type);
        } catch (Exception e) {
            e.printStackTrace();
            return DataResult.getResult(400, "查询失败");
        }
        return DataResult.success(list);
    }

原因：该接口有个boolean参数没有添加@RequestParam注解，随后加上该注解，swagger又可以加载了
