准备工作

注册真正的支付宝账号
在百度搜索支付宝开放平台搜索到的网址：https://open.alipay.com/dev/workspace/
用真正的支付宝账号登录
选择沙箱环境
打开沙箱应用页面在控制台中查看到APPID：
沙箱账号这个账号一会项目启动起来，支付时会使用到
启用系统默认密钥

具体编码工作第一步：创建SpringBoot项目，添加依赖：


    org.springframework.boot
    spring-boot-starter-web



    org.projectlombok
    lombok
    true




    com.alipay.sdk
    alipay-easysdk
    2.2.0

第二步：修改application.yml

server:
  port: 80
  servlet:
    context-path: /wego
alipay:
  #阿里支付
  appId: 2021000118674150
  #应用私钥
  appPrivateKey: 
  #支付宝公钥
  alipayPublicKey: 
  notifyUrl:

其中：在这里插入图片描述 notifyUrl是成功之后，阿里巴巴将支付结果回传到我们自己项目中的url的地址，此时需要网络穿透，请参看博客：内网穿透工具 netapp

第三步：读取alipay配置文件的配置类：AlipayConfig

@Getter
@Setter
@Component
@ConfigurationProperties(prefix = "alipay")
public class AlipayConfig {
   private String appId;
   private String appPrivateKey;
   private String alipayPublicKey;
   private String notifyUrl;

   @PostConstruct
   public void init(){
      Config options = getOptions();
      options.appId = this.appId;
      options.merchantPrivateKey=this.appPrivateKey;
      options.alipayPublicKey = this.alipayPublicKey;
      options.notifyUrl = this.notifyUrl;
      Factory.setOptions(options);
      System.out.println("支付宝初始化成功！");
   }

   private Config getOptions(){
      Config config = new Config();
      config.protocol="https";
      config.gatewayHost="openapi.alipaydev.com";
      config.signType="RSA2";
      return config;
   }
}

第四步：定义支付相关的控制器：AlipayController

@RestController
@RequestMapping("/v1/alipay")
public class AlipayController {
    //http://localhost/wego/v1/alipay/pay?subject=aabbcc&tradeNo=1001&totalAmount=8888
    @GetMapping(value = "/pay", produces = "text/html;charset=utf-8")
    String pay(String subject, String tradeNo, String totalAmount) {
        AlipayTradePagePayResponse response = null;
        //发起API调用
        try {
            response = Factory.Payment.Page().pay(subject, tradeNo, totalAmount, "");
        } catch (Exception e) {
            System.err.println("支付时遇到异常：");
            e.printStackTrace();
        }
        System.out.println(response.getBody());
        return response.getBody();
    }


    @PostMapping("/notify")
    String payNotify(HttpServletRequest request) throws Exception {
        System.out.println("pay notify");
        String tradeStatus = request.getParameter("trade_status");
        System.out.println(tradeStatus);
        if ("TRADE_SUCCESS".equals(tradeStatus)) {
            System.out.println("支付宝异步回调");
            Map params = new HashMap();
            Map requestParams = request.getParameterMap();
            for (String name : requestParams.keySet()) {
                params.put(name, request.getParameter(name));
            }
            String tradeNo = params.get("out_trade_no");
            String gmtPayment = params.get("gmt_payment");

            //支付宝验签
            if (Factory.Payment.Common().verifyNotify(params)) {
                System.out.println("交易名称：" + params.get("subject"));
                System.out.println("交易状态：" + params.get("trade_status"));
                System.out.println("支付宝交易凭证号：" + params.get("trade_no"));
                System.out.println("商户订单号：" + params.get("out_trade_no"));
                System.out.println("交易金额：" + params.get("total_amount"));
                System.out.println("买家在支付宝唯一ID：" + params.get("buyer_id"));
                System.out.println("买家付款时间：" + params.get("gmt_payment"));
                System.out.println("买家付款金额：" + params.get("buyer_pay_amount"));
                //更新订单为已支付
                //....
            }
        }
        return "success";
    }
}

第五步：运行程序测试
