SpringBoot接入支付宝
- (一)、前提工作:
- 1、进入支付宝开发平台—沙箱环境
- 1.1、进入个人沙箱环境
- 1.2、接下来进行几个密钥的生成
- 1.3、拿到两个密钥后，进行自定义密钥配置
- 1.4、至此，我们沙箱环境的配置和基本参数都已经获取到。
- (二)、Java代码-thymeleaf
- 1.导入两个包
- 2.编写两个代码
- 3.控制层代码优化
(一)、前提工作:
1、进入支付宝开发平台—沙箱环境
沙箱环境-支付宝文档中心
1.1、进入个人沙箱环境
参考文档
点击进入沙箱环境并用支付宝登陆
沙箱管理界面如图所示
appid，支付宝网关，自定义密钥等
这里是沙箱支付宝（虚拟）的账号和密码，可以用来支付
1.2、接下来进行几个密钥的生成
点击进入密钥工具
点击生成
这时我们拿到两个密钥，将它们保存，这两个密钥很重要
应用私钥
应用公钥
1.3、拿到两个密钥后，进行自定义密钥配置
进入最开始的沙箱管理界面，点击自定义密钥，点击设置（查看），我们选择的是RSA2密钥
选择“公钥”这一选项
将上一步骤生成的应用公钥填进来，会得到支付宝公钥这另一个密钥，记住并保存这个支付宝公钥
1.4、至此，我们沙箱环境的配置和基本参数都已经获取到。
(二)、Java代码-thymeleaf
1.导入两个包
导入一个包
我用的开发语言是JAVA，工具为IDEA，一个简单的springboot工程
1.构建一个普通的springboot工程，引入支付宝SDK的maven依赖：
<!--支付宝支付接口-->
<dependency>
<groupId>com.alipay.sdk</groupId>
<artifactId>alipay-sdk-java</artifactId>
<version>3.0.0</version>
</dependency>
<!-- thymeleaf -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
<version>2.7.7</version>
</dependency>
2.编写两个代码
新建一个AlipayConfig类，用于配置支付的相关配置：
里面的配置信息，标记是你的就写你的。没标记就照搬
package com.jsxs.config;
import java.io.FileWriter;
import java.io.IOException;
public class AlipayConfig {
// 应用ID,您的APPID，收款账号既是您的APPID对应支付宝账号,开发时使用沙箱提供的APPID，生产环境改成自己的APPID
public static String APP_ID = "122620920";
// 商户私钥，您的PKCS8格式RSA2私钥
public static String APP_PRIVATE_KEY = "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\n";
// 支付宝公钥,您的 查看地址：https://openhome.alipay.com/platform/keyManage.htm 对应APPID下的支付宝公钥。

/**

*/
public static void logResult(String sWord) {
FileWriter writer = null;
try {
writer = new FileWriter(log_path + "alipay_log_" + System.currentTimeMillis()+".txt");
writer.write(sWord);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (writer != null) {
try {
writer.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}
新建一个controller包，用于存放Action，新建一个PayController类,编写一个用于支付的接口/pay
package com.jsxs.controller;
import com.alipay.api.AlipayApiException;
import com.alipay.api.AlipayClient;
import com.alipay.api.DefaultAlipayClient;
import com.alipay.api.request.AlipayTradePagePayRequest;
import com.jsxs.config.AlipayConfig;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@Controller
public class PayController {
@RequestMapping("/pay")
public void payController(HttpServletRequest request, HttpServletResponse response) throws IOException {
//获得初始化的AlipayClient
AlipayClient alipayClient = new DefaultAlipayClient(AlipayConfig.gatewayUrl, AlipayConfig.APP_ID, AlipayConfig.APP_PRIVATE_KEY, "json", AlipayConfig.CHARSET, AlipayConfig.ALIPAY_PUBLIC_KEY, AlipayConfig.sign_type);
//设置请求参数
AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();
alipayRequest.setReturnUrl(AlipayConfig.return_url);
alipayRequest.setNotifyUrl(AlipayConfig.notify_url);
//商户订单号，商户网站订单系统中唯一订单号，必填
String out_trade_no = new String(request.getParameter("WIDout_trade_no").getBytes("ISO-8859-1"), "UTF-8");
//付款金额，必填
String total_amount = new String(request.getParameter("WIDtotal_amount").getBytes("ISO-8859-1"), "UTF-8");
//订单名称，必填
String subject = new String(request.getParameter("WIDsubject").getBytes("ISO-8859-1"), "UTF-8");
//商品描述，可空
String body = new String(request.getParameter("WIDbody").getBytes("ISO-8859-1"), "UTF-8");
alipayRequest.setBizContent("{\"out_trade_no\":\"" + out_trade_no + "\","
+ "\"total_amount\":\"" + total_amount + "\","
+ "\"subject\":\"" + subject + "\","
+ "\"body\":\"" + body + "\","
+ "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
//若想给BizContent增加其他可选请求参数，以增加自定义超时时间参数timeout_express来举例说明
//alipayRequest.setBizContent("{\"out_trade_no\":\""+ out_trade_no +"\","
// + "\"total_amount\":\""+ total_amount +"\","
// + "\"subject\":\""+ subject +"\","
// + "\"body\":\""+ body +"\","
// + "\"timeout_express\":\"10m\","
// + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
//请求参数可查阅【电脑网站支付的API文档-alipay.trade.page.pay-请求参数】章节
//请求
String form = "";
try {
form = alipayClient.pageExecute(alipayRequest).getBody(); //调用SDK生成表单
} catch (AlipayApiException e) {
e.printStackTrace();
}
response.setContentType("text/html;charset=" + AlipayConfig.CHARSET);
response.getWriter().write(form);//直接将完整的表单html输出到页面
response.getWriter().flush();
response.getWriter().close();
}
@RequestMapping("/")
public String toTest(){
return "index";
}
}
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<form action="/pay" method="post">
订单号：<input type="text" name="WIDout_trade_no" required><br/>
订单名称：<input type="text" name="WIDsubject" required><br/>
付款金额：<input type="text" name="WIDtotal_amount" required><br/>
WIDbody：<input type="text" name="WIDbody"><br/>
<input type="submit" value="下单"> <input type="reset" value="重置">
</form>
required保证提交的时候这两项内容非空
5. controller类添加跳转html页面的映射：
@RequestMapping("/")
public String toTest(){
return "index";
}
6.测试运行，启动项目，在浏览器输入：http://localhost:8080/
3.控制层代码优化
