springboot整合支付宝支付

前言：基于支付宝沙箱环境开发

开发环境

java1.8
maven 3.3.9
springboot 2.1.3.RELEASE
MuMu模拟器
支付宝app（沙箱版）

第一步：获取支付宝支付所需的公钥和私钥

1、登陆支付宝开放平台

https://open.alipay.com/platform/home.htm
登陆进开放平台后，找到 “研发服务”，点击进去

2、生成密钥

注意：密钥的生成需要借助支付宝提供的工具来生成。

工具下载地址：https://opendocs.alipay.com/open/291/105971

安装完成后，打开工具，完成密钥的生成：

3、配置密钥

将步骤2.2中生成的密钥配置到下图中即可。

注意：密钥需要妥善保存！！！开发时需要用到！

第二步：代码开发

1、新建一个maven项目，并导入依赖包

 <!-- 支付宝SDK --><dependency><groupId>com.alipay.sdk</groupId><artifactId>alipay-sdk-java</artifactId><version>4.13.0.ALL</version></dependency><!-- 支付宝SDK依赖的日志 --><dependency><groupId>commons-logging</groupId><artifactId>commons-logging</artifactId><version>1.2</version></dependency>

2、参考开发文档

详细参数参见：https://docs.open.alipay.com/203/107090/，
https://docs.open.alipay.com/api_1/alipay.trade.wap.pay

标记蓝色的由支付宝sdk（开发工具包）设置、标记红色的已在支付渠道参数中配置，标记绿色的需程序来设置。

3、编写代码

@Controller
public class PayTestController {String APP_ID = "2021000117673208";String APP_PRIVATE_KEY ="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";String ALIPAY_PUBLIC_KEY ="MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAqx2R+1BRRRY2Z4Du3aJwJrTEAR6iAwTY88A6bCk+V1ZDHc36dCvan4X4lmHehfFnYnqhzE0E/7hwAtUTwKVTj6RZgTBWIFw6OCNdebO7bhhTVhJ4Pl/WI2TPH2meWnCADE/UeYIJf/BVIE540Z8J0fvuaedRa1YF9+rAQIwBqj1KnDyXL4UV0Mc69vclc/tw84EzSUIhOpSDepyLMPps+lAKVVMQeQmWfzdafMOq3hoLI4NAxLDuxZWjRKypgKQaXYBzG3TBjTDiI6bc+ehEv4jz+2OfxITXgUS9aQAyKb1dg11birCDWU0Kj/uCjIDeTl9DOS/Ixi6i+UrSssBGHwIDAQAB";String CHARSET = "utf-8";String serverUrl = "https://openapi.alipaydev.com/gateway.do"; //正式"https://openapi.alipay.com/gateway.do"@GetMapping("/alipaytest")public void alipaytest(HttpServletRequest httpRequest, HttpServletResponse httpResponse)throws IOException {AlipayClient alipayClient = new DefaultAlipayClient(serverUrl, APP_ID, APP_PRIVATE_KEY, "json", CHARSET, ALIPAY_PUBLIC_KEY, "RSA2"); //获得初始化的AlipayClientAlipayTradeWapPayRequest alipayRequest = new AlipayTradeWapPayRequest();//创建API对应的requestalipayRequest.setBizContent("{" +" \"out_trade_no\":\"20150320010101123\"," +" \"total_amount\":\"0.01\"," +" \"subject\":\"Iphone6 16G\"," +" \"product_code\":\"QUICK_WAP_PAY\"" +" }");  //填充业务参数String form="";try {form = alipayClient.pageExecute(alipayRequest).getBody();  //调用SDK生成表单} catch (AlipayApiException e) {e.printStackTrace();}httpResponse.setContentType("text/html;charset=" + CHARSET);httpResponse.getWriter().write(form);  //直接将完整的表单html输出到页面httpResponse.getWriter().flush();httpResponse.getWriter().close();}
}

第三步：测试（基于模拟器）

1、生成访问二维码

百度在线生成二维码，二维码的链接为：http://192.168.xxx.xxx:端口/项目名称/alipaytest

2、安装mumu模拟器

下载地址：https://mumu.163.com/

3、在模拟器上安装支付宝（沙箱版）

注意：支付宝沙箱版不稳定，如果出现报错，可以试多几次！

下载地址（需要先登陆开放平台）：https://open.alipay.com/platform/appDaily.htm?tab=info

在模拟器中安装支付宝：

4、登陆支付宝

登陆支付宝开放平台，在沙箱环境中获取登陆账号和密码：

调用支付宝的 “扫一扫” ，选择上面生成的二维码：

至此，完成！！！
