layUI的分页不起作用

问题：点击页数无效，问题在总条数

1.前端分页传的是page,limit.

2.前端jq

    layui.use(['form', 'table'], function () {
        var $ = layui.jquery,
            form = layui.form,
            table = layui.table;

        table.render({
            elem: '#currentTableId',
            url: '/tuserList',
            toolbar: '#toolbarDemo',
            defaultToolbar: ['filter', 'exports', 'print', {
                title: '提示',
                layEvent: 'LAYTABLE_TIPS',
                icon: 'layui-icon-tips'
            }],
            cols: [[
                {type: "checkbox", width: 50},
                {field:'id', width:150, title: 'ID', sort: true},
                {field: 'username', width: 150, title: '用户名'},
                {field: 'number', width: 150, title: '账号', sort: true},
                {field: 'phone', width: 150, title: '手机号码'},
                {field: 'email', title: '邮箱', minWidth: 150},
                {title: '操作', minWidth: 150, toolbar: '#currentTableBar', align: "center"}
            ]],
            limits: [10, 15, 20, 25, 50, 100],
            limit: 10,
            page: true,
            skin: 'line'
        });

        // 监听搜索操作
        form.on('submit(data-search-btn)', function (data) {
            var username=$("#username").val();

            //执行搜索重载
            table.reload('currentTableId', {
                page: {
                    curr: 1
                }
                , where: {
                    username: username
                }
            }, 'data');

            return false;
        });

3.controller的分页其中用到了分页插件PageHelper,因为框架的问题所以返回的结果类型要一致

 /**
     * 使用分页插件获取用户的list
     * @return
     */
    @RequestMapping(value = "/tuserList")
    @ResponseBody
    public JSONObject userList(HttpServletRequest request,TUser user, @RequestParam( required = false,value = "page",defaultValue = "1") int pageNum,@RequestParam( required = false,value = "limit",defaultValue = "10") int pageSize ){
        JSONObject jsonObject=new JSONObject();
        System.out.println(user.getUsername());
        System.out.println(request.getParameter("username"));
        List list = userService.userPage(pageNum,pageSize,user);
        //使用分页插件
        PageInfo pageInfo=new PageInfo<>(list);
        if (CollectionUtils.isNotEmpty(list)){
            jsonObject.put("code",0);
            jsonObject.put("msg","请求成功");
            jsonObject.put("count",pageInfo.getTotal());
            jsonObject.put("data",pageInfo.getList());
        }
        return jsonObject;
    }

4.service层

    //用户的分页
    public List userPage(int pageNum,int pageSize,TUser user);

5.serviceImpl层

    @Override
    public List userPage(int pageNum,int pageSize,TUser user) {
        //查询出全部数据
        PageHelper.startPage(pageNum,pageSize);
        List userList=baseMapper.userPage(user);

        return userList;
    }

6.mapper层

    public List userPage(@Param("user") TUser user);

7.mapper.xml

 
        select * from t_user
        
            <if test="user.username !=null and user.username !=''">
                and username=#{user.username}
            if>
