在Spring控制器中使用日期参数的最佳实践？

在编写了几个后端API之后,我发现以下代码几乎在每个需要按日期过滤数据的方法中都重复:

@GetMapping(value="/api/test")
@ResponseBody
public Result test(@RequestParam(value = "since", required = false) @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) LocalDate since,
                   @RequestParam(value = "until", required = false) @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) LocalDate until) {
    // Date validation code I want to eliminate
    since = ObjectUtils.defaultIfNull(since, DEFAULT_SINCE_DATE);
    until = ObjectUtils.defaultIfNull(until, LocalDate.now().plusDays(1));
    if(since.isAfter(until)) {
        throw new SinceDateAfterUntilDateException();
    }

    // Do stuff
}
