PageHelper这么用

@GetMapping("/list")
    public R getUserList(@RequestParam(value = "page", defaultValue = "1") Integer page, @RequestParam(value = "pageSize", defaultValue = "10") Integer pageSize, HttpSession session, String search) {
        //PageHelper分页插件
        PageHelper.startPage(page, pageSize);
        //按名称模糊查询
        QueryWrapper<User> queryWrapper = new QueryWrapper<>();
        if (search != null && search != "") {
            queryWrapper.like("user_name", search);
        }
        List<User> list = userService.list(queryWrapper);
        //将需要分页的数据集合，引入PageHelper分页插件的PageInfo类
        PageInfo<User> pageInfo = new PageInfo<User>(list, 10);
        session.setAttribute("page", pageInfo);
        return new R(true, pageInfo);
    }
