@RequestParam 注解使用是bug ,未查明问题原因 也可能是 Pageable 的原因

    @GetMapping
    @ResponseBodypublic Object findAll(@RequestParam(value = "page", required = false, defaultValue = "0") Integer page,
                          @RequestParam(value = "pageSize", required = false, defaultValue = "10") Integer pageSize, String data) {
        Pageable pageable = PageRequest.of(page, pageSize, Sort.Direction.DESC, "id");
        Predicate predicate = getPredicate(data);
        Page<Invite> pageResult = inviteService.findByProperties(pageable, predicate);
        return Response.list(pageResult.getContent(), (int) pageResult.getTotalElements());
    }

        page = null != page ? --page : 0;
        pageSize = null != pageSize ? pageSize : 10;
        Pageable pageable = PageRequest.of(page, pageSize, Sort.Direction.DESC, "id");
        Predicate predicate = getPredicate(data);
        Page<Invite> pageResult = inviteService.findByProperties(pageable, predicate);
        List<Invite> list = inviteService.findListByProperties(predicate);
        System.out.println("list====[]"+list);
        logger.debug("list====={}",list);
        return Response.list(pageResult.getContent(), (int) pageResult.getTotalElements())

　

　第一种写法无法会使得Page产生错误 具体原因未知:

 正确的方式:一脸懵逼 参数哪里不一样吗?
