后台实现：

    @RequestMapping(value = "/dataGrid", method = RequestMethod.POST)
    @ResponseBody
    public PageInfo dataGrid(UserVo userVo, Integer page, Integer rows, String sort, String order) {
        PageInfo pageInfo = new PageInfo(page, rows);
        Map<String, Object> condition = Maps.newHashMap();

        if (StringUtils.isNoneBlank(userVo.getName())) {
            condition.put("name", userVo.getName());
        }
        if (userVo.getOrganizationId() != null) {
            condition.put("organizationId", userVo.getOrganizationId());
        }
        if (userVo.getCreatedateStart() != null) {
            condition.put("startTime", userVo.getCreatedateStart());
        }
        if (userVo.getCreatedateEnd() != null) {
            condition.put("endTime", userVo.getCreatedateEnd());
        }
        pageInfo.setCondition(condition);
        userService.findDataGrid(pageInfo);
        return pageInfo;
    }
