How bootstrap-table implements server paging

This article mainly introduces the example of bootstrap-table to implement server paging (spring background), which has certain reference value. If you are interested, you can learn about it

The bootstrap table plug-in is used in the front-end recently. , client-side paging is not good for interaction when the amount of data is too large, so the server-side is used for paging large amounts of data. Let’s start with the code

Front-end

Let’s take a look first What are the default paging parameters of bootstrap table?

• Which index does offset start from?

• limit The number of limits per page

Maybe it is different from our default paging parameters, so we decided to change it. The parameters passed to the background are

• page. Which page starts from 0

• size The number displayed per page

  $('#' + tableId).bootstrapTable({

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

Backstage

 @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;
 }

Note

The parameters received by bootstrap table must include total and rows. Total is the total number and rows is the number of each page
