前端传给后端的数据如下后端的代码如下@ApiOperation("添加二级活动")@RequestMapping(value = "/AddEventInFo", method = RequestMethod.POST)@ResponseBodypublic CommonResult AddEventInFo(@RequestParam(required = false) Integer eventId, @RequestParam(required = false) String eventInfoName, @RequestParam(required = false) String eventType, @RequestParam(required = false, value = "eventDate[]") String[] eventDate, @RequestParam(required = false, value = "beginDate[]") String[] beginDate, @RequestParam(required = false, value = "reachDate[]") String[] reachDate, @RequestParam(required = false) String periodFlag, @RequestParam(required = false) String periodType, @RequestParam(required = false) String periodFrequency, @RequestParam(required = false) String referFlag ) throws ParseException { EventInfo eventInfo = new EventInfo(); eventInfo.setEventId(eventId); eventInfo.setEventInfoName(eventInfoName); eventInfo.setEventType(eventType); eventInfo.setEventStartDate(sdf.parse(eventDate[0])); eventInfo.setEventEndDate(sdf.parse(eventDate[1])); eventInfo.setBeginStartDate(sdf.parse(beginDate[0])); eventInfo.setBeginEndDate(sdf.parse(beginDate[1])); eventInfo.setReachStartDate(sdf.parse(reachDate[0])); eventInfo.setReachEndDate(sdf.parse(reachDate[1])); eventInfo.setPeriodFlag(periodFlag); eventInfo.setPeriodType(periodType); eventInfo.setPeriodFrequency(periodFrequency); eventInfo.setReferFlag(referFlag); int result = eventService.addEventInfo(eventInfo); if(result > 0){ return CommonResult.success("添加二级活动成功"); }else { return CommonResult.failed("添加二级活动失败"); }}大佬们啊，帮忙看看后端现在，除了传的几个日期数组，接收不到，其他参数都能接收到，问题出在哪里呀？请大佬指点
