JAVA 小程序支付统一付款

商户系统和微信支付系统主要交互说明 [图片] 步骤1：用户在商户APP中选择商品，提交订单，选择微信支付。步骤2：商户后台收到用户支付单，调用微信支付统一下单接口。参见【统一下单API】。步骤3：统一下单接口返回正常的prepay_id，再按签名规范重新生成签名后，将数据传输给APP。参与签名的字段名为appid，partnerid，prepayid，noncestr，timestamp，package。注意：package的值格式为Sign=WXPay 步骤4：商户APP调起微信支付。api参见本章节【app端开发步骤说明】步骤5：商户后台接收支付通知。api参见【支付结果通知API】步骤6：商户后台查询支付结果。，api参见【查询订单API】 API链接：https://pay.weixin.qq.com/wiki/doc/api/app/app.php?chapter=8_3 支付的流程为：先调用统一下单API 接着在小程序wx.requestPayment发起支付支付完之后会调用支付结果通知 [图片] 后台Java代码：(基于SpringMVC) [代码]/**[代码] [代码] [代码][代码]* 统一下单[代码] [代码] [代码][代码]* @param userId[代码] [代码] [代码][代码]* @param activityId[代码] [代码] [代码][代码]* @param
