java实现微信支付结果通知

时间:2022-11-17 17:27:22

支付完成后,微信会把相关支付结果和用户信息发送给商户,商户需要接收处理,并返回应答。

对后台通知交互时,如果微信收到商户的应答不是成功或超时,微信认为通知失败,微信会通过一定的策略定期重新发起通知,尽可能提高通知的成功率,但微信不保证通知最终能成功。 (通知频率为15/15/30/180/1800/1800/1800/1800/3600,单位:秒)

注意:同样的通知可能会多次发送给商户系统。商户系统必须能够正确处理重复的通知。
推荐的做法是,当收到通知进行处理时,首先检查对应业务数据的状态,判断该通知是否已经处理过,如果没有处理过再进行处理,如果处理过直接返回结果成功。在对业务数据进行状态检查和处理之前,要采用数据锁进行并发控制,以避免函数重入造成的数据混乱。

特别提醒:商户系统对于支付结果通知的内容一定要做签名验证,防止数据泄漏导致出现“假通知”,造成资金损失。
