前后端交互传参问题，help~

Question

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)
@ResponseBody
public 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

1. 因为你value写错了 不能加[] 去掉括号即可，value对应的是你的参数名
2. 这种最好是创建一个param对象最好
