• 对接支付宝

    1.引入依赖 （后期版本可能会更新）

    2.     com.alipay.sdk
    3.     alipay-sdk-java
    4.     4.23.0.ALL

    2，写配置类

    1. @Configuration
    2. public class AlipayClientConfig{
    3.     @Value("${ali-pay.app-id}")
    4.     private String appId;
    5.     @Value("${ali-pay.merchant-private-key}")
    6.     private String merchantPrivateKey;
    7.     @Value("${ali-pay.ali-pay-public-key}")
    8.     private String aliPayPublicKey;
    9.     @Value("${ali-pay.gateway-url}")
    10.     private String gatewayUrl;
    11.     @Bean
    12.     public AlipayClient alipayClient() throws AlipayApiException{
    13.         AlipayConfig alipayConfig=new AlipayConfig();
    14.         //设置appId
    15.         alipayConfig.setAppId(appId);
    16.         //设置商户私钥
    17.         alipayConfig.setPrivateKey(merchantPrivateKey);
    18.         //设置支付宝公钥
    19.         alipayConfig.setAlipayPublicKey(aliPayPublicKey);
    20.         //设置支付宝网关
    21.         alipayConfig.setServerUrl(gatewayUrl);
    22.         //设置请求格式,固定值json.
    23.         alipayConfig.setFormat(AlipayConstants.FORMAT_JSON);
    24.         //设置字符集
    25.         alipayConfig.setCharset(AlipayConstants.CHARSET_UTF8);
    26.         //设置签名类型
    27.         alipayConfig.setSignType(AlipayConstants.SIGN_TYPE_RSA2);
    28.         //构造client
    29.         AlipayClient alipayClient=new DefaultAlipayClient(alipayConfig);
    30.         return alipayClient;
    31.     }
    32. }

    3.配置字段说明

    1. ali-pay:
    2.   #接下来两个用来标识用户
    3.   #商户id
    4.   pid: xxxxxxxxxxx
    5.   #应用appid(和商户id绑定过)
    6.   app-id: xxxxxxxxxxx
    7.   #接下来三个用来确保SSL
    8.   #商户私钥
    9.   merchant-private-key: xxxxxxxxxxx
    10.   #支付宝公钥
    11.   ali-pay-public-key: xxxxxxxxxxx
    12.   #TODO:  #对称加密密钥
    13.   #  content-key:
    14.   #接下来三个是相关地址
    15.   #支付宝网关
    16.   gateway-url: https://openapi.alipaydev.com/gateway.do
    17.   #接收结果通知地址
    18.   notify-url: xxxxxxxxxxx
    19.   #页面跳转同步通知页面路径
    20.   return-url: xxxxxxxxxxx

    4.其他

    1. public class AliPayConstant{
    2.     public static final String TRADE_STATE_SUCCESS="TRADE_SUCCESS";
    3.     public static final String REFUND_STATE_SUCCESS="REFUND_SUCCESS";
    4. }

    5.创建支付功能 小程序文档 - 支付宝文档中心

    1. private String createPay(OrderInfo orderInfo){
    2.     //请求
    3.     AlipayTradePagePayRequest request=new AlipayTradePagePayRequest();
    4.     //数据
    5.     AlipayTradePagePayModel bizModel=new AlipayTradePagePayModel();
    6.     bizModel.setOutTradeNo(orderInfo.getOrderNo());
    7.     //单位是元
    8.     bizModel.setTotalAmount(orderInfo.getTotalFee()
    9.                             .toString());
    10.     bizModel.setSubject(orderInfo.getTitle());
    11.     //默认的
    12.     bizModel.setProductCode("FAST_INSTANT_TRADE_PAY");
    13.     request.setBizModel(bizModel);
    14.     request.setNotifyUrl(notifyUrl+"/pay/order/pay-signal");
    15.     //用户支付后支付宝会以GET方法请求returnUrl,并且携带out_trade_no,trade_no,total_amount等参数.
    16.  
    17.     request.setReturnUrl(returnUrl);
    18.     AlipayTradePagePayResponse response=null;
    19.     try{
    20.         //完成签名并执行请求
    21.         response=alipayClient.pageExecute(request);
    22.         if(response.isSuccess()){
    23.             log.debug("调用成功");
    24.             return response.getBody();
    25.         }
    26.         else{
    27.             log.error("调用失败");
    28.             log.error(response.getMsg());
    29.             return null;
    30.         }
    31.     }
    32.     catch(AlipayApiException e){
    33.         log.error("调用异常");
    34.         return null;
    35.     }
    36. }

    返回的是一个表单 需要前端进行处理，随后可以直接扫码或者使用只用支付号账号登录进行付款

    6.支付回调结果通知  小程序文档 - 支付宝文档中心

    1. @PostMapping("/pay-signal")
    2. public String paySignal(@RequestBody Map data){
    3.     log.debug("收到支付宝回调");
    4.     //验签

    31.                     //交易类型(扫码 登录等等)
    32.                     paymentInfo.setTradeType("扫码/登录支付");
    33.                     paymentInfo.setTradeState(data.get("trade_status"));

    35.                     paymentInfo.setContent(gson.toJson(data));
    36.                     paymentInfoService.save(paymentInfo);
