Java对接支付宝的支付、退款、提现
|
本篇主要是正对Java对接支付宝的常用功能，需要开通个人的沙箱环境和内网穿透（我用了阿里云服务器）。 集成前提:开发者在集成和开发前需要了解一下常用的接入方式和架构建议，如下图所示：
1、登录网页版的个人支付宝 https://auth.alipay.com/login/ant_sso_index.htm
https://opendocs.alipay.com/open/200/105311
5.1、请求入口代码 package com.example.mybaties.controller; import com.example.mybaties.result.BaseResponse; import com.example.mybaties.result.ResultGenerator; import com.example.mybaties.service.AliPayService; import io.swagger.annotations.Api; import io.swagger.annotations.ApiOperation; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * @description: 支付宝下单支付 * @author: lst * @date: 2020-12-01 16:58 */ @RestController @RequestMapping("/pay") @Api(value = "AliPayController", tags = "支付宝下单支付") public class AliPayController { @Autowired private AliPayService aliPayService; /** * @Description 支付宝下单支付 * @author lst * @date 2020-12-1 17:27 * @return com.example.mybaties.result.BaseResponse */ @PostMapping(value = "/place-order", produces = "application/json; charset=utf-8") @ApiOperation(value = "支付宝下单支付", notes = "支付宝下单支付", produces = "application/json") public BaseResponse placeOrder() { return ResultGenerator.genSuccessResult(aliPayService.placeOrder()); } /** * @Description 网页版支付宝下单支付 * @author lst * @date 2020-12-2 14:16 * @return com.example.mybaties.result.BaseResponse */ @PostMapping(value = "/alipay-page", produces = "application/json; charset=utf-8") @ApiOperation(value = "网页版支付宝下单支付", notes = "网页版支付宝下单支付", produces = "application/json") public void alipayPage(HttpServletResponse response) { aliPayService.alipayPage(response); } /** * @Description 支付宝提现 * @author lst * @date 2020-12-2 17:03 * @param response */ @PostMapping(value = "/alipay-withdraw", produces = "application/json; charset=utf-8") @ApiOperation(value = "支付宝提现", notes = "支付宝提现", produces = "application/json") public void withdraw(HttpServletResponse response) { aliPayService.withdraw(response); } /** * @Description 支付宝退款 * @author lst * @date 2020-12-21 14:19 * @param response */ @PostMapping(value = "/alipay-refund", produces = "application/json; charset=utf-8") @ApiOperation(value = "支付宝退款", notes = "支付宝退款", produces = "application/json") public void refund(HttpServletResponse response) { aliPayService.refund(response); } /** * @Description 支付宝支付成功后,回调该接口 * @author lst * @date 2020-12-1 17:27 * @param request * @param response * @return java.lang.String */ @RequestMapping(value="/notify",method={RequestMethod.POST,RequestMethod.GET}) @ApiOperation(value = "支付宝支付成功后,回调该接口", notes = "支付宝支付成功后,回调该接口", produces = "application/json") public String notify(HttpServletRequest request, HttpServletResponse response) { return aliPayService.notifyData(request,response); } }5.2、实现层代码 package com.example.mybaties.service.impl; import com.example.mybaties.form.AlipayBean; import com.example.mybaties.form.AlipayRefundForm; import com.example.mybaties.form.WithdrawBean; import com.example.mybaties.service.AliPayService;

/** * 商户私钥，您的PKCS8格式RSA2私钥 */ private String merchantPrivateKey; /** * 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。 */ private String alipayPublicKey; /** * 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 * 支付宝会悄悄的给我们发送一个请求，告诉我们支付成功的信息 */ private String notifyUrl; /** * 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 * 同步通知，支付成功，一般跳转到成功页 */ private String returnUrl; /** * 签名方式 */ private String signType; /** * 字符编码格式 */ private String charset; /** * 支付宝网关； https://openapi.alipaydev.com/gateway.do 正式环境 https://openapi.alipay.com/gateway.do */ private String gatewayUrl; /** * 该笔订单允许的最晚付款时间，逾期将关闭交易 */ private String timeoutExpress; /** * 请求的格式：json */ private String format; }5.5、网页支付代码orderPage.html、下单成功代码success.html 网页下单 function placeOrder() { var url = "/pay/alipay-page"; $.ajax({ url: url, type: 'POST', dataType: 'JSON', success: function (data) { console.log(data); $('#orderPage').html(data) }, error: function (msg) { } }); } 成功页面 恭喜下单成功 6、打入服务器进行测试输入网址点击‘提交’ 按钮，后端已经默认支付数据，我用沙箱APP支付成功后可以跳转到成功页面。
手机端也可以测试 HwVideoEditor
