springboot调用支付宝沙箱扫码支付

springboot调用支付宝沙箱虚拟支付,测试版

1.在支付宝官网填写申请沙箱个人相关信息

支付宝官网:https://openhome.alipay.com/platform/home.htm

进入官网,找到沙箱,在这需要需要用到自己的APPID,密钥私钥,密钥私钥需要配置,还是很简单的

这个就是我们的虚拟支付宝沙箱,可以直接扫码下载

这里面就是自己的信息,金额可以随意充值,不过有最大限制,最大可充值9999999.99元

2.pom引入支付宝jar

  <!--支付宝沙箱-->
        <dependency>
            <groupId>com.alipay.sdk</groupId>
            <artifactId>alipay-sdk-java</artifactId>
            <version>3.0.0</version>
        </dependency>

3.创新对象的支付页面以及类和方法

配置类

package com.wyh.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 = "";
    // 商户私钥，您的PKCS8格式RSA2私钥
    public static String APP_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
    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(其实就是支付成功后返回的页面)
    public static String return_url = "http://localhost:8080/alipay.trade.page.pay-JAVA-UTF-8/return_url.jsp";
    // 签名方式
    public static String    sign_type = "RSA2";
    // 字符编码格式
    public static String CHARSET = "utf-8";
    // 支付宝网关，这是沙箱的网关
    public static String gatewayUrl = "https://openapi.alipaydev.com/gateway.do";
    // 支付宝网关
    public static String log_path = "C:\\";

    public static void logResult(String sWord) {
        FileWriter writer = null;
        try {

                } catch (IOException e) {

                }
            }
        }
    }

}
