Java中Spring Boot支付宝扫码支付及支付回调的实现代码

2021-08-11 12:20Yy夜雨 Java教程

这篇文章主要介绍了Java中Spring Boot支付宝扫码支付及支付回调的实现代码,本文给大家介绍的非常详细,对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下

前言:最近开发支付宝支付功能,总结一下做个分享

官方文档:https://opendocs.alipay.com/apis
支付宝沙箱地址: https://openhome.alipay.com/platform/appDaily.htm?tab=info
支付宝支付流程:

准备工作:获取支付宝沙箱数据(appid,支付宝网关,rsa2秘,沙箱支付账号等)
集成springboot,使用java代码发起支付请求
支付宝收到支付请求后,返回html代码片段,用于前端展示二维码
扫码支付成功后,支付宝发送同步、异步通知请求,同步、异步通知路径可在配置文件中进行配置
收到异步通知结果后,进行验签,验签通过,返回成功信息通知支付宝不在进行异步通知
此时支付宝支付流程完成,调用支付宝查询接口,确认支付成功

一、获取支付宝沙箱数据

打开上述沙箱地址,获取沙箱配置,查看下图信息

二、集成springboot,使用java代码发起支付请求

1、在pom.xml文件添加支付宝依赖

<!-- 支付宝支付 -->
        <dependency>
            <groupid>com.alipay.sdk</groupid>
            <artifactid>alipay-sdk-java</artifactid>
            <version>3.7.26.all</version>
        </dependency>

2、在项目中新建一个支付宝工具类

public class alipayconfig {
    // ↓↓↓↓↓↓↓↓↓↓请在这里配置您的基本信息↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
 
    // 应用id,您的appid,收款账号既是您的appid对应支付宝账号
    public static string app_id = "";
 
    // 商户私钥,您的pkcs8格式rsa2私钥
    public static string merchant_private_key = "";
 
    // 支付宝公钥,查看地址:https://openhome.alipay.com/platform/keymanage.htm 对应appid下的支付宝公钥。
    public static string alipay_public_key = "";
 
    // 服务器异步通知页面路径 需http://格式的完整路径,不能加?id=123这类自定义参数,必须外网可以正常访问
    
    // 这里需要配置支付宝回调的后端路径,必须要外网可以访问
    public static string notify_url = "http://localhost:8080/alipay.trade.page.pay-java-utf-8/notify_url.jsp";
    
    // 页面跳转同步通知页面路径 需http://格式的完整路径,不能加?id=123这类自定义参数,必须外网可以正常访问

    // 支付宝网关
    public static string gatewayurl = "https://openapi.alipaydev.com/gateway.do";
 
    // 日志路径
    public static string log_path = "c:\\";
 
    // ↑↑↑↑↑↑↑↑↑↑请在这里配置您的基本信息↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑
 
    /**
     * 写日志,方便测试(看网站需求,也可以改成把记录存入数据库)
     *
     * @param sword 要写入日志里的文本内容
     */
    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();
                }
            }
        }
    }
}

3、定义service

public interface alipayservice {
 
  /**
   * 发起支付
   * @param outtradeno  订单编号(唯一)
   * @param totalamount  订单价格
   * @param subject    商品名称
   */
  string gopay(string outtradeno,bigdecimal totalamount,string subject) throws exception;
  
  /**
   * 交易查询
   * @param outtradeno 订单编号(唯一)
   */
  string query(string outtradeno) throws alipayapiexception;
  
  /**
   * 交易关闭
   * @param outtradeno订单编号(唯一)
   */
  string close(string outtradeno) throws alipayapiexception;
}

4、实现serviceimpl,发起支付请求,交易查询等

        alipaytradepagepayrequest alipayrequest = new alipaytradepagepayrequest();
 
        /** 同步通知,支付完成后,支付成功页面 */
        alipayrequest.setreturnurl(alipayconfig.return_url);

        /** 请求接口 */
        alipayrequest.setbizcontent("{\"out_trade_no\":\"" + outtradeno + "\"," + "\"trade_no\":\"" + "" + "\"}");
        /** 转换格式 */
        string result = alipayclient.execute(alipayrequest).getbody();
        return result;

    @override
    public string close(string outtradeno) throws alipayapiexception {
        alipaytradecloserequest alipayrequest = new alipaytradecloserequest();
        alipayclient alipayclient = new defaultalipayclient(alipayconfig.gatewayurl, alipayconfig.app_id,

        string result = alipayclient.execute(alipayrequest).getbody();
