# 沙箱环境 #

# 1:先去蚂蚁金服入驻 #

得到开发需要的信息 appid 支付宝网管 商户私钥和支付宝公钥

# 2:配置参数类 #

# pom引入jar包 #

<dependency>
                <groupId>com.alipay.sdk</groupId>
                <artifactId>alipay-sdk-java</artifactId>
                <version>3.1.0</version>
            </dependency>

# 配置支付宝需要的参数配置 #

package com.fandemi.utils.alipay;
    
    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
        public static String app_id = "appid";
        // 支付宝网关
        public static String url = "https://openapi.alipaydev.com/gateway.do";
        // 商户私钥，您的PKCS8格式RSA2私钥
        public static String 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 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 = "";
    
        // 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
        public static String return_url = "";
        // 签名方式
        public static String sign_type = "RSA2";// 签名方式
        public static String format = "json";//参数格式为json
        // 字符编码格式
        public static String charset = "utf-8";
    
    
    }

# 3:配置参数实体类 #

package com.fandemi.utils.alipay;
    
    public class AlipayBean {
        /**
         * 商户订单号，必填
         *
         */
        private String out_trade_no;
        /**
         * 订单名称，必填
         */
        private String subject;
        /**
         * 付款金额，必填
         * 根据支付宝接口协议，必须使用下划线
         */
        private String total_amount;
        /**
         * 商品描述，可空
         */
        private String body;
        /**
         * 超时时间参数
         */
        private String timeout_express= "10m";
        /**
         * 产品编号
         */
        private String product_code= "FAST_INSTANT_TRADE_PAY";
    
        public String getOut_trade_no() {
            return out_trade_no;
        }
        public void setOut_trade_no(String out_trade_no) {
            this.out_trade_no = out_trade_no;
        }
        public String getSubject() {
            return subject;
        }
        public void setSubject(String subject) {
            this.subject = subject;
        }
        public String getTotal_amount() {
            return total_amount;
        }
        public void setTotal_amount(String total_amount) {
            this.total_amount = total_amount;
        }
        public String getBody() {
            return body;
        }
        public void setBody(String body) {
            this.body = body;
        }
        public String getTimeout_express() {
            return timeout_express;
        }
        public void setTimeout_express(String timeout_express) {
            this.timeout_express = timeout_express;
        }
        public String getProduct_code() {
            return product_code;
        }
        public void setProduct_code(String product_code) {
            this.product_code = product_code;
        }
    }

# 4:编写支付业务代码service实现类 #

/**
         * 支付宝支付接口
         * @param orderNo   订单号
         * @param payMoney  支付金额

         */
        @Override

            try {
                AlipayClient alipayClient = new DefaultAlipayClient(
                    AlipayConfig.url,//支付宝网管
                    AlipayConfig.app_id,//appid

                    AlipayConfig.format,//json格式
                    AlipayConfig.charset,//编码格式
                    AlipayConfig.public_key,//公钥
                    AlipayConfig.sign_type);//签名方式
                AlipayTradeAppPayRequest appPayRequest = new AlipayTradeAppPayRequest();
                AlipayTradeAppPayModel model = new AlipayTradeAppPayModel();
                model.setBody("我是测试数据");
                model.setSubject("App支付测试Java");
                //请保证OutTradeNo值每次保证唯一
                model.setOutTradeNo(alipayBean.getOut_trade_no());//订单号
                model.setTimeoutExpress("30m");//超时时间 自定义
                model.setTotalAmount(alipayBean.getTotal_amount());//前台传的支付金额 string类型
                model.setProductCode("QUICK_MSECURITY_PAY");//写死
                appPayRequest.setBizModel(model);
                appPayRequest.setNotifyUrl(AlipayConfig.notify_url);//回调地址
                //这里和普通的接口调用不同，使用的是sdkExecute
                AlipayTradeAppPayResponse response = alipayClient.sdkExecute(appPayRequest);
                System.out.println(response.getBody());//就是orderString 可以直接给客户端请求，无需再做处理。
                return response.getBody();
            } catch (AlipayApiException e) {
