沙箱环境

沙箱环境也就是特意为开发者准备的环境，从而避免去注册公司、审核之类的问题！这个是沙箱环境的链接

先要下载这两个工具

环境一定要配置正确，尤其是秘钥之类的，至于回调地址先不考虑，如果要测试的话首先要保证你本机的服务可以映射到公网，内网穿透就是一种解决方案，而且域名还便宜!

开始

支付包第三方Jar引入：

xml
<dependency>
  <groupId>com.alipay.sdk</groupId>
  <artifactId>alipay-sdk-java</artifactId>
  <version>3.0.0</version>
</dependency>

在resources目录下新建一个支付宝的配置文件：alipay.properties

properties
# 应用ID,您的APPID，收款账号既是您的APPID对应支付宝账号
app_id = 2016092900623298
# 商户私钥，您的PKCS8格式RSA2私钥
merchant_private_key = 你生成的商户私钥
# 支付宝公钥 对应APPID下的支付宝公钥。
alipay_public_key = 你的支付宝公钥
# 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
notify_url = http://106.12.202.93:8080/pay/payFinish
# 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
return_url = http://106.12.202.93:8080/pay/paySyncFinish
# 签名方式
sign_type = RSA2
# 字符编码格式
charset = utf-8
# 支付宝网关
gatewayUrl = https://openapi.alipaydev.com/gateway.do

Controller层：

java
package edu.xpu.game.controller.shopping;

@Slf4j
@Controller
@RequestMapping("/pay")
public class PayController {
    private final OrderServiceImpl orderService;
    private final PayServiceImpl payService;

    @Autowired
    public PayController(OrderServiceImpl orderService, PayServiceImpl payService) {
        this.orderService = orderService;
        this.payService = payService;
    }

    @ResponseBody
    @RequestMapping("/affirmPay")
    public String payOrder(@RequestParam("masterOrderId") String masterOrderId){
        Optional<OrderMaster> byId = orderService.findOrderById(masterOrderId);

        AlipayBean alipayBean = new AlipayBean();
        alipayBean.setOut_trade_no(masterOrderId); //设置订单Id
        alipayBean.setSubject("农家商城购物");

        if(byId.isPresent()){
            alipayBean.setTotal_amount(new StringBuffer()
                                       .append(byId.get().getOrderAmount()));
            try {
                String aliPay = payService.aliPay(alipayBean);
                log.info("[pay.affirmPay] aliPay = {}", aliPay);
                return aliPay;
            } catch (AlipayApiException e) {
                return JsonUtil.toJson(ResultVOUtil.error(2, "支付过程出错"));
            }
        }else{
            return JsonUtil.toJson(ResultVOUtil.error(1, "不存在此订单"));
        }
    }

    /**
     * 支付成功的回调
     * @param trade_status 交易状态
     * @param out_trade_no 商户订单号
     */
    @RequestMapping("/payFinish")
    public void payFinishCallback(String trade_status, String out_trade_no){
        log.info("支付回调：trade_status = "+trade_status);
        if("TRADE_SUCCESS".equals(trade_status)){
            //支付成功
            Optional<OrderMaster> orderById = orderService.findOrderById(out_trade_no);
            if(orderById.isPresent()){
                OrderMaster orderMaster = orderById.get();
                //修改支付状态
                orderMaster.setPayStatus(PayStatusEnum.SUCCESS.getCode());
                OrderMaster changeRet = orderService.change(orderMaster);
                log.info("changeRet", changeRet);
            }
        }else{
            //支付失败
            Optional<OrderMaster> orderById = orderService.findOrderById(out_trade_no);
            if(orderById.isPresent()){
                OrderMaster orderMaster = orderById.get();
                //修改支付状态
                orderMaster.setPayStatus(PayStatusEnum.WAIT.getCode());
                orderService.change(orderMaster);
            }
        }
    }


    @RequestMapping("/paySyncFinish")
    public String paySyncFinishCallback(){
        return "redirect:http://ahojcn.natapp1.cc/#/pay";
    }
}

支付宝支付信息实体类对象

java
@Data
@Accessors(chain = true)
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*/
    private StringBuffer total_amount;
    /*商品描述，可空*/
    private String body;
    /*超时时间参数*/
    private String timeout_express="10m";

    private String product_code="FAST_INSTANT_TRADE_PAY";
}

Service层

java
@Service
public class PayServiceImpl implements PayService {
    @Override
    public String aliPay(AlipayBean alipayBean) throws AlipayApiException {
        return AlipayUtil.connect(alipayBean);
    }
}

支付工具类

java
public class AlipayUtil {
    public static String connect(AlipayBean alipayBean) throws AlipayApiException {
        AlipayClient alipayClient = new DefaultAlipayClient(
                PropertiesConfig.getKey("gatewayUrl"),//支付宝网关
                PropertiesConfig.getKey("app_id"),//appid
                PropertiesConfig.getKey("merchant_private_key"),//商户私钥
                "json",

                PropertiesConfig.getKey("alipay_public_key"),//支付宝公钥
                PropertiesConfig.getKey("sign_type")//签名方式
        );
        AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();
        alipayRequest.setReturnUrl(PropertiesConfig.getKey("return_url"));
        alipayRequest.setNotifyUrl(PropertiesConfig.getKey("notify_url"));
        alipayRequest.setBizContent(JSON.toJSONString(alipayBean));
        return alipayClient.pageExecute(alipayRequest).getBody();
    }

可以使用Android版本的沙箱支付宝支付，也可以登录账户支付，沙箱环境不是很稳定最好多测试几次，支付成功和支付失败的情景！
