请求参数中包含HttpServletRequest 怎么去请求

下边这个接口怎么请求,怎么调通

 @ResponseBody
    @ApiOperation(value = "品牌系列表list列表")
    @RequestMapping(value = "/list.json", method = RequestMethod.POST)
    public IPage<BrandSet> getBrandSetList(@RequestAttribute("chachedUser") Staff user, HttpServletRequest req, HttpServletResponse res,
                                           @RequestParam(defaultValue = "1") Integer pageNumber,
                                           @RequestParam(defaultValue = "20") Integer pageSize) {

不用在意HttpServletRequest ，那个是tomcat赋值的，你要关心是需要手动去入参数的那些
