Java使用Queryable-pageable实现分页

    @ResponseBody
    @RequestMapping(value = "getLbjzkList", method = RequestMethod.GET)
    @PageableDefaults(sort = "id=desc")
    private void ajaxList(Queryable queryable, PropertyPreFilterable propertyPreFilterable, HttpServletRequest request,
        HttpServletResponse response) throws IOException {
        EntityWrapper<LbjZk> entityWrapper = new EntityWrapper<LbjZk>(entityClass);
        propertyPreFilterable.addQueryProperty("id");
        propertyPreFilterable.addQueryProperty("name");
       Integer page= Integer.parseInt(request.getParameter("page").toString());
       Integer rows= Integer.parseInt(request.getParameter("rows").toString());

        // 预处理
        queryable.setPageable(new PageRequest(page, rows));
        QueryableConvertUtils.convertQueryValueToEntityValue(queryable, entityClass);
        SerializeFilter filter = propertyPreFilterable.constructFilter(entityClass);
        PageJson<LbjZk> pagejson = new PageJson<LbjZk>(lbjZkService.list(queryable,entityWrapper));
        String content = JSON.toJSONString(pagejson, filter);
        StringUtils.printJson(response, content);
    }
