开始

service

和分页查询有关的

复制一段之前写的

 /**
     * 获取分页的订单流向
     * @param userId
     * @param page
     * @param pageSize
     * @return
     */
    public PagedGridResult getMyOrdersTrend(String userId
                                            ,Integer page
                                            ,Integer pageSize);

实现类

  @Transactional(propagation = Propagation.SUPPORTS)
    @Override
    public PagedGridResult getMyOrdersTrend(String userId, Integer page, Integer pageSize) {
        Map<String,Object> map=new HashMap<>();
        map.put("userId",userId);
        PageHelper.startPage(page,pageSize);
        List<OrderStatus> list = ordersMapperCustom.getMyOrderTrend(map);


        return setterPagedGrid(list,page);
    }

确保当前MyOrdersServiceImpl继承了BaseService要不然无法调用setterPagedGrid方法。

public class MyOrderServiceImpl extends BaseService implements MyOrderService {}

这里的方法就可以去掉了

controller

前端

循环展示数据

根据状态查询


这里发现前端一个小bug修改后。

后端

MyOrdersController

@ApiOperation(value = "查询订单动向",notes = "查询订单动向",httpMethod ="POST" )
    @PostMapping("/trend")
    public IMOOCJSONResult trend(
            @ApiParam(name = "userId",value = "用户id",required = true)
            @RequestParam String userId,
            @ApiParam(name = "page",value = "查询下一页的第几页",required = false)
            @RequestParam Integer page,
            @ApiParam(name = "pageSize",value = "分页的每一页显示的条数",required = false)
            @RequestParam Integer pageSize){
        if(StringUtils.isBlank(userId)){
            return IMOOCJSONResult.errorMsg(null);
        }
        if(page==null){
            page=1;
        }
        if(pageSize==null){
            pageSize=COMMON_PAGE_SIZE;
        }
        PagedGridResult grid = myOrderService.getMyOrdersTrend(userId,
                page,
                pageSize);

        return IMOOCJSONResult.ok(grid);
    }
