java微信延遲支付的實現(xiàn)示例

更新時間：2024年01月18日 09:28:22 作者：mob6454cc7c268c

最近在面試的過程中總會出現(xiàn)一些關(guān)于微信支付延遲返回結(jié)果的處理方式的問題,本文主要介紹了java微信延遲支付的實現(xiàn)示例,具有一定的參考價值,感興趣的可以了解一下

1.需求

下單支付后，支付回調(diào)因部分因素不可達，導(dǎo)致訂單狀態(tài)與微信支付狀態(tài)不一致。此時需要服務(wù)端主動查詢訂單支付狀態(tài)，進行更改訂單狀態(tài)。

2.實現(xiàn)方式

基于定時任務(wù)
每隔30秒啟動一次，找出最近10分鐘內(nèi)創(chuàng)建并且未支付的訂單，調(diào)用微信查單接口核實訂單狀態(tài)。系統(tǒng)記錄訂單查詢的次數(shù)，在n次查詢之后狀態(tài)還是未支付成功，則停止后續(xù)查詢，并調(diào)用關(guān)單接口關(guān)閉訂單。

基于延時隊列
每隔5秒/30秒/1分鐘/3分鐘/5分鐘/10分鐘/30分鐘調(diào)用查單接口，若查詢付款成功，不再執(zhí)行隊列任務(wù)，最后一次查詢?nèi)暨€是未返回支付成功狀態(tài)，則停止后續(xù)查詢，并調(diào)用《關(guān)單接口》關(guān)閉訂單。

延時隊列實現(xiàn)方式（這里不做詳細(xì)描述，優(yōu)缺點自行百度，本文采用redis實現(xiàn)）

delayqueue
RabbitMQ
reids

3.具體代碼

新建實體類 DelayQueueJob 與 ScoredSortedItem

    /**
