spring boot下支付宝的开箱既用环境

alipay-sdk-java当前最新版本

使用场景

spring boot应用中需要接入支付宝

开始使用

  1. pom.xml中引入依赖
<dependency>
    <groupId>net.guerlab</groupId>
    <artifactId>sdk-alipay-starter</artifactId>
</dependency>
  1. bootstrap.yml中增加配置
alipay:
  dev: true/false #默认false,为true表示使用沙箱环境
  sign-type: RSA2 #签名算法
  app-id: #应用ID
  private-key: #应用私钥
  alipay-public-key: #支付宝公钥
  1. 增加控制器实现

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;

import com.alibaba.fastjson.JSONObject;
import com.alipay.api.AlipayClient;
import com.alipay.api.request.AlipayTradeAppPayRequest;
import com.alipay.api.request.AlipayTradePagePayRequest;
import com.alipay.api.request.AlipayTradeWapPayRequest;

import net.guerlab.sdk.alipay.properties.AlipayProperties;
import net.guerlab.sdk.alipay.utils.NotifyUtils;

@Controller
@RequestMapping("/alipay")
public class AlipayController {

    @Autowired
    private AlipayClient client;//支付宝请求sdk客户端
    
    @Autowired
    private AlipayProperties properties;//支付宝sdk配置

    /**
     * 支付请求
     */
    @GetMapping
    public String pay(HttpServletResponse httpResponse) {
        JSONObject data = new JSONObject();
        data.put("out_trade_no", "201701010000001234"); //商户订单号
        data.put("product_code", "QUICK_MSECURITY_PAY"); //产品码, APP支付 QUICK_MSECURITY_PAY, PC支付 FAST_INSTANT_TRADE_PAY, 移动H5支付 QUICK_WAP_PAY
        data.put("total_amount", "0.01"); //订单金额
        data.put("subject", "测试订单"); //订单标题

        //APP支付
        AlipayTradeAppPayRequest request = new AlipayTradeAppPayRequest();
        //PC支付

        //移动H5支付
        //AlipayTradeWapPayRequest request = new AlipayTradeWapPayRequest();
        request.setNotifyUrl("http://demo/alipay/notify"); //异步通知地址
        request.setBizContent(data.toJSONString()); //业务参数

        //APP支付
        return client.sdkExecute(request).getBody();
        //PC支付
        //try {
        //    PrintWriter writer = httpResponse.getWriter();
        //    httpResponse.setContentType("text/html;charset=UTF-8");
        //    writer.write(client.pageExecute(request).getBody());
        //    writer.flush();
        //    writer.close();
        //    return null;
        //} catch (Exception e) {
        //    LOGGER.debug(e.getMessage(), e);
        //    return "创建支付信息失败";
        //}
        //移动H5支付
        //try {
        //    PrintWriter writer = httpResponse.getWriter();
        //    httpResponse.setContentType("text/html;charset=UTF-8");
        //    writer.write(client.pageExecute(request).getBody());
        //    writer.flush();
        //    writer.close();
        //    return null;
        //} catch (Exception e) {
        //    LOGGER.debug(e.getMessage(), e);
        //    return "创建支付信息失败";
        //}
    }

    /**
     * 异步通知相应
     */
    @PostMapping("/notify")
    public String notify(HttpServletRequest request) {
        if (!NotifyUtils.rsaCheck(properties, request.getParameterMap())) {
            //这里处理验签失败
        }

        request.getParameter("trade_no");//获取请求参数中的商户订单号

        return "success";
    }
}
