@RequestMapping(value = "/getSettlements", method = RequestMethod.GET, headers = "Accept=application/json")
  public @ResponseBody
            Collection<Settlement> getSettlements
            (@RequestParam(value = "startDate") String startDate,
            @RequestParam(value = "endDate") String endDate,
            @RequestParam(value = "merchantIds", defaultValue = "null") String merchantIds)

如何在defaultValue中提供今天的日期？它只需要不变.
