PageHelper同一个接口中分页2次集合

    @ApiOperation("查询")
    @GetMapping(value = "/business")
    @ResponseBody
    public  Map<String, Object> findBusiness(@ApiParam("页码") @RequestParam(value = "page", defaultValue = "1") Integer page,
                                         @ApiParam("查询数量") @RequestParam(value = "pageSize", defaultValue = "10") Integer pageSize
                                         ) { 
List<Business> list;
            //判断 是否为空
            if (StringUtils.isBlank(id)) {
                
                PageHelper.startPage(page, pageSize, "");
                list = service.findBusiness();
            } else {
                PageHelper.startPage(page, pageSize, "");
                list = service.findBusinessOrder();
            }

 PageInfo<Business> page = new PageInfo<Business>(list);
 Map<String, Object> map = new HashMap<String, Object>();
        map .put("list", page);
return map;
}
    

 PageHelper.startPage(page, pageSize, "");需要分开写，否则分页不成功！！！！
