}- 加配置(前端支付页面的地址)：alipay.returnUrl=http://localhost:8080/orders
- AlipayConfig.java 加一个属性：returnUrl
- AliPayController.java的pay接口设置回调的url：request.setReturnUrl(aliPayConfig.getReturnUrl());
window.open('http://localhost:9090/alipay/pay?traceNo=' + row.orderNo + "&totalAmount=" + row.price + '&subject=' + row.name)
以上即全部的内容，配置完之后就可以实现了
