bootstrap-table 服务器分页 （spring 后台

最近前端都是用的bootstrap table这个插件，客户端分页的话数据量一多交互不好，所以大数据量的分页都用服务器端，下面开始撸代码

前端

首先看下bootstrap table 默认传的分页参数是什么

• offset 从哪个下标开始
• limit 每页限制的数量

可能跟我们的默认分页参数不大一样吧，所以决定改造一下,传到后台的参数为

• page 第几页 从0开始
• size 每页显示的数量

     $('#' + tableId).bootstrapTable({
                    queryParams: function (e) {  
                        var param = {  
                            size: e.limit,  
                            page: (e.offset / e.limit),//不需要+1  
                            
                        };  
                        return param;  
                    },
                  sidePagination:“server”;
});

后台

    @ApiOperation(value = "获取企业列表，支持分页", notes = "json方法获取用户列表")
    @ApiImplicitParams({ @ApiImplicitParam(name = "name", value = "企业名称", required = true, dataType = "string"),
    @ApiImplicitParam(name = "beginTime", value = "开始时间", required = true, dataType = "string") })
    @RequestMapping(value="/list",method=RequestMethod.POST)
    @ResponseBody
    public  Map<String,Object> list(@RequestParam Map<String,Object> map,@RequestParam(required = false) String name, @RequestParam(required = false) String beginTime, @RequestParam(required = false) String endTime, @RequestParam(required = false) Integer deptid){
        List<Map<String,Object>> list = new ArrayList<>();
        //当前页数
        int page = map.get("page")== null ? 0 : Integer.parseInt(map.get("page").toString());
        // 每页行数
        int size = map.get("size") == null ? 10 : Integer.parseInt(map.get("size").toString());
        Order order = new Order(Direction.ASC,"id");
        Order order1 = new Order(Direction.DESC,"createTime");
        List<Order> orders = new ArrayList<Order>();
        orders.add(order1);//先按照createTime 降序排序  然后按照id升序
        orders.add(order);
        Sort sort = new Sort(orders);
        Pageable pageable = new PageRequest(page,size,sort);
        Page<Company> companyPages = null;
        if(StringKit.isEmpty(name)){
            companyPages = companyService.companyDao.findAll(pageable);
        }else{
            companyPages = companyService.companyDao.findByNameLike(name,pageable);
        }

        List<Company> companyList = companyPages.getContent();
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        for(Company company:companyList){
            Map<String,Object> mapTemp = BeanKit.describe(company);
            mapTemp.put("createTime", sdf.format(company.getCreateTime()));
            list.add(mapTemp);
        }
         Map<String,Object> data = new HashMap<String,Object>();
         data.put("total", companyPages.getTotalElements());
         data.put("rows", list);
        return data;
    }

注意点

bootstrap table接收的参数中必须要有total和rows，total就是总数量，rows是每页的数量

展示一下效果图吧
