注解@PathVariable 的使用

 映射中传值

  
    @GetMapping("beacons/{currentPage}/{pageSize}")
    public ResultData findAllBeacon(@PathVariable("pageSize") int pageSize,@PathVariable("pageCount") int pageCount) {

        int pageStart = (pageSize - 1) * pageCount;
        List beaconList = beaconDao.findAll(pageStart,pageCount);
        Long count = beaconDao.getTotalCount();
        if (beaconList != null) {
            return ResultData.ok().putDataValue("beacons", beaconList).putDataValue("totalCount",count);
        } else {
            return ResultData.notFound();
        }
    }

仍可如下写法,

@GetMapping("{currentPage}/{pageSize}/beacons")

映射中传值先后顺序不同，代表的映射地址亦不同。
