微信小程序支付，查询和支付回调

微信支付经常用到，做个详细的demo！！！

为了配置好更换，我一般都是把配置放在数据库。

pom依赖

订单小工具

public class OrderUtil {public static String getGeneralOrder() {Date date=new Date();String newString = String.format("%0"+4+"d", (int)((Math.random()*9+1)*1000));SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");String format = sdf.format(date);return format+newString;}
}

提交支付后返给前端的参数

public interface WxPayService {//微信小程序支付Result wxPay(String orderId, String openId, String name, BigDecimal amount);//支付回调逻辑boolean orderUpdate(PayTransaction payTransaction, Integer type);//微信退款  支付方式(1app微信 2微信公众号 3微信小程序 9h5微信) 支付单号 退款金额  订单编号boolean wxRefund(Integer payWay, String payNum, String payMoney, String orderNum, Long ordersId, BigDecimal totalFee);//查询订单boolean getQueryOrder(String orderNum);
