支付宝支付网页端

1,：先调用支付宝支付接口，帮返回的form表单返给前端

2：前端触发submit按钮自动跳转

3：用户支付后触发 同步和异步

public class PayMentUtil {
   
   

//配置文件实体类
    private final PayMent payMent;


    public AlipayTradePagePayResponse pay(OrderDto orderDto) throws AlipayApiException {
   
   


      
        AlipayClient alipayClient = new DefaultAlipayClient(payMent.getGatewayUrl(), payMent.getAppId(), payMent.getRsaPrivateKey(), payMent.getFormat(), payMent.getCharset(), payMent.getAlipayPublicKey(), payMent.getSignType());
     
        AlipayTradePagePayRequest request = new AlipayTradePagePayRequest();
     //同步触发  返回的页面
        request.setNotifyUrl(payMent.getNotifyUrl());
       //异步触发  支付完成后触发
        request.setReturnUrl(payMent.getReturnUrl());
        System.out.println(request);
        JSONObject bizContent = new JSONObject();
        bizContent.put("out_trade_no", orderDto.getOrderNo());
        bizContent.put("total_amount", orderDto.getTotalAmount().divide(bigDecimal));
        bizContent.put("subject", orderDto.getProductName());
     
      
        bizContent.put("product_code", "FAST_INSTANT_TRADE_PAY");
