Springboot后端使用Form表单防重复提交的代码

1. redisCache
2. key:value;
   value里面存放请求数据的信息（body,以及时间）
   如果存在则比较， 请求参数， 发送的时间。
   如果不存在则直接将 请求信息和发送时间 放到redisCache里面

private int intervalTime = 10;

public void setIntervalTime(int intervalTime)
{
    
    
    this.intervalTime = intervalTime;
}
public boolean isRepeatSubmit(HttpServletRequest request)
{
    
    
    // 本次参数及系统时间
    RepeatedlyRequestWrapper repeatedlyRequest = (RepeatedlyRequestWrapper) request;
    String nowParams = HttpHelper.getBodyString(repeatedlyRequest);

    // body参数为空，获取Parameter的数据
    if (StringUtils.isEmpty(nowParams))
    {
    
    
        nowParams = JSONObject.toJSONString(request.getParameterMap());
    }
    Map<String, Object> nowDataMap = new HashMap<String, Object>();
    nowDataMap.put(REPEAT_PARAMS, nowParams);
    nowDataMap.put(REPEAT_TIME, System.currentTimeMillis());

    // 请求地址（作为存放cache的key值）
    String url = request.getRequestURI();

    HttpSession session = request.getSession();
    Object sessionObj = redisCache.getCacheObject(SESSION_REPEAT_KEY);
    if (sessionObj != null)
    {
    
    
        Map<String, Object> sessionMap = (Map<String, Object>) sessionObj;
        if (sessionMap.containsKey(url))
        {
    
    
            Map<String, Object> preDataMap = (Map<String, Object>) sessionMap.get(url);
            if (compareParams(nowDataMap, preDataMap) && compareTime(nowDataMap, preDataMap))
            {
    
    
                return true;
            }
        }
    }
    Map<String, Object> cacheMap = new HashMap<String, Object>();
    cacheMap.put(url, nowDataMap);
    redisCache.setCacheObject(SESSION_REPEAT_KEY, cacheMap, intervalTime, TimeUnit.SECONDS);
    return false;
}
