首先去支付宝开发平台入驻[https://open.alipay.com/][https_open.alipay.com]

# 1：开发入驻 #

输入信息入驻后进入 **研发服务--》沙箱**

# 2：查看**appid和支付宝网关** #

因为是沙箱环境 所以网关统一都是测试环境 [https://openapi.alipaydev.com/gateway.do][https_openapi.alipaydev.com_gateway.do]

# 3：生成密钥 #

在沙箱环境中配置应用公钥

# 4：配置 #

新建配置

package com.sinosoft.config;
    
    public class AlipayConfig {
        //客户appid
        public static String APPID="第二步的appid";
        //私钥
        public static String RSA_PRIVATE_KEY="应用私钥 第三步需要配置到java中的";
        //服务器异步通知页面路径
        public static String notify_url="http://www.baidu.com";
        public static String return_url="http://www.baidu.com";
        //请求网关地址
        public static String URL="https://openapi.alipaydev.com/gateway.do";
        //编码
        public static String CHARSET = "UTF-8";
        //返回格式
        public static String FORMAT="json";
        //支付宝公钥
        public static String ALIPAY_PUBLIC_KEY="配置应用公钥之后生成的支付宝公钥";
        //RSA2
        public static String SIGNTYPE="RSA2";
    }

# 5：编写请求页面和java #

package com.sinosoft.controller;
    
    import com.alipay.api.AlipayApiException;
    import com.alipay.api.AlipayClient;
    import com.alipay.api.DefaultAlipayClient;
    import com.alipay.api.domain.AlipayTradePagePayModel;
    import com.alipay.api.request.AlipayTradePagePayRequest;
    import com.alipay.api.response.AlipayTradePagePayResponse;
    import com.sinosoft.config.AlipayConfig;
    import org.springframework.web.bind.annotation.PostMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    import java.util.HashMap;
    import java.util.Map;
    import java.util.UUID;
    
    @RestController
    public class OrderController {
        /**
         * 阿里支付
         */
        @PostMapping("/oalipay")
        public String alipay(String out_trade_no,String subject,String total_amount,String body,String product_code) throws AlipayApiException {
            AlipayConfig alipayConfig = new AlipayConfig();
            //封装RSA签名方式
            AlipayClient alipayClient = new DefaultAlipayClient(
                    alipayConfig.URL,//请求网关
                    alipayConfig.APPID,//收款ID
                    alipayConfig.RSA_PRIVATE_KEY,//私钥
                    alipayConfig.FORMAT,//返回格式
                    alipayConfig.CHARSET,//字符编码格式
                    alipayConfig.ALIPAY_PUBLIC_KEY,//支付宝公钥
                    alipayConfig.SIGNTYPE);//加密方式
            //创建request
            AlipayTradePagePayRequest request = new AlipayTradePagePayRequest();
            //设置异步回调地址
            request.setNotifyUrl(alipayConfig.notify_url);
            //设置同步回调地址
            request.setReturnUrl(alipayConfig.return_url);
            //封装参数
            AlipayTradePagePayModel model = new AlipayTradePagePayModel();
            model.setOutTradeNo(UUID.randomUUID().toString());//商品id
            model.setBody(body);//商品描述
            model.setSubject(subject);//商品名称
            model.setTimeoutExpress("30m");//超市
            model.setTotalAmount(total_amount);//支付金额
            model.setProductCode("FAST_INSTANT_TRADE_PAY");
            //设置request参数
            request.setBizModel(model);
            /*alipayRequest.setBizContent("{\"out_trade_no\":\"" + out_trade_no + "\","
                    + "\"total_amount\":\"" + total_amount + "\","
                    + "\"subject\":\"" + subject + "\","
                    + "\"body\":\"" + body + "\","
                    + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");*/
    
            //生成表单
            AlipayTradePagePayResponse alipayTradePagePayResponse = alipayClient.pageExecute(request);
            String result = alipayTradePagePayResponse.getBody();
            return result;
        }
    }
