隊列+多線程+couchbase緩存 ，解決高并發(fā)問題。

調(diào)用處：

ulong c = CouchBaseProvider.Increment("TAG_CLAIMCOUNT_USER",userId.ToString(), 1, 1, new TimeSpan(2, 0, 0));//couchbase自增函數(shù)if (c > 1)//couchebase判斷是否領(lǐng)取過 {resp.Code = -1010;resp.Message = "您已在隊列里面";}else //couchebase判斷是否領(lǐng)完 {int nums = Convert.ToInt32(CouchBaseProvider.Increment(Constants.TAG_CLAIMCOUNT, userId.ToString()));if (nums > Allnums){resp.Code = -1011;resp.Message = "人數(shù)已滿";}else{//TODO 進入隊列Queueparam p= new Queueparam();p.Name= userName;p.UID = System.Guid.NewGuid().ToString();p.redOrder = redOrder;TestQueue.Enqueue(p);int maxWait = 30000;TestQueue queue = new TestQueue();resp = await MonitorThread.WaitForReslut(p.UID, maxWait);}}
