paypal简单例子

支付配置

        PayPalConfigStorage storage = new PayPalConfigStorage();
        storage.setClientID("商户id");
        storage.setClientSecret("商户密钥");
        storage.setTest(true);
        //发起付款后的页面转跳地址
        storage.setReturnUrl("http://127.0.0.1:8088/pay/success");
        //取消按钮转跳地址,这里用异步通知地址的兼容的做法
        storage.setNotifyUrl("http://127.0.0.1:8088/pay/cancel");
           
        

网络请求配置

        HttpConfigStorage httpConfigStorage = new HttpConfigStorage();
        
      /* /网络请求连接池**/
        //最大连接数
        httpConfigStorage.setMaxTotal(20);
        //默认的每个路由的最大连接数
        httpConfigStorage.setDefaultMaxPerRoute(10);
        

创建支付服务

    //支付服务
     PayService service = new PayPalPayService(configStorage);

     //设置网络请求配置根据需求进行设置
     //service.setRequestTemplateConfigStorage(httpConfigStorage)
     

创建支付订单信息

        //支付订单基础信息
         PayOrder order = new PayOrder("Order_payment:", "Order payment", price, UUID.randomUUID().toString().replace("-", ""), PayPalTransactionType.sale);
  

网页支付

        //币种
        order.setCurType(CurType.USD);
        Map orderInfo = service.orderInfo(order);
        service.buildRequest(orderInfo, MethodType.POST);

授权回调处理

        /*-----------回调处理-------------------*/
           //HttpServletRequest request;
         Map<String, Object> params = service.getParameter2Map(request.getParameterMap(), request.getInputStream());
        if (service.verify(params)){
            System.out.println("支付成功");
            return;
        }
        System.out.println("支付失败");


        /*-----------回调处理-------------------*/

申请退款接口

      RefundOrder order = new RefundOrder();
      order.setCurType(CurType.USD);
      order.setDescription(" description ");
      order.setTradeNo("paypal 平台的单号");
      order.setRefundAmount(BigDecimal.valueOf(0.01));
        RefundResult result =  service.refund(order);
