java - Spring mvc 分页

Question

你好，我的项目使用jqgrid，我需要实现分页，所以我在php中找到了一段代码并将其复制到java中:

@RequestMapping(value = "getgriddata", method = RequestMethod.GET)
    public @ResponseBody
    String getGrid(@RequestParam("page") String page, @RequestParam("rows") int rownumber, @RequestParam("sidx") String sortBy, @RequestParam("sord") String sortOrder,@RequestParam(value = "_search") String search, @RequestParam(value="filters", required = false) String filters) {

        int totalCount = dao.getTotalRecordCount();

        CustomJsonResponse response = new CustomJsonResponse();

        int totalPages = 0;

        if (totalCount > 0) {
            totalPages = (int) Math.ceil(totalCount/rownumber);
        }

        if (Integer.valueOf(page) > totalPages) {
            page = String.valueOf(totalPages);
        }

        Gson jsonConverter = new Gson();

        int start = (rownumber * Integer.valueOf(page)) - rownumber;
        Filters searchFilter = null;

        if(Boolean.valueOf(search) == true){
            searchFilter = jsonConverter.fromJson(filters, Filters.class);
        }

        // Retrieve records from database
        List<Record> recorBatch = dao.getRecords(start, rownumber, sortBy, sortOrder, search, searchFilter);

        // Assign the result from the service to this response
        response.setRows(recorBatch);
        response.setTotal(String.valueOf(totalPages));
        response.setRecords(String.valueOf(stagingLoadBatch.size()));
        response.setPage(page);

        return jsonConverter.toJson(response);
    }

当我处理整组数据时，这可以正常工作，但是当我缩小搜索范围(即在某个时间间隔内选择记录)时，分页就会崩溃。我意识到这是不好的做法，我从这段代码中复制了它用于分页:

有人可以为此提出更好的解决方案吗？

我建议你看看Display Tag Library ，用于分页。
