1注册一个沙箱号网站https://open.alipay.com/platform/home.htm
使用真的支付宝扫描进去注册沙箱支付宝

2）进去注册信息

3）注册成功就进去点击开发中心

4）接下来下载密匙生成工具
下载完毕解压

更新秘钥工具2021-01-19

我以上传到百度网盘下载安装即可使用

提取码：ephw

5）进入沙箱把生成的公钥放进就去就会自动生成支付宝公钥了

6）接下来创建Java项目,在我们的pom文件中添加支付宝提供的支付相关坐标

<dependency><groupId>com.alipay.sdk</groupId><artifactId>alipay-sdk-java</artifactId><version>3.3.49.ALL</version>
</dependency>

结构很简单一个controller 就可以

创建支付Controller,并准备支付所需参数

可以参考下图
SpringMVC

@Controller
public class PayController {private final String APP_ID = "应用的APPID";private final String APP_PRIVATE_KEY = "生成的应用私钥";private final String CHARSET = "UTF-8";private final String ALIPAY_PUBLIC_KEY = "支付宝公钥";//这是沙箱接口路径,正式路径为https://openapi.alipay.com/gateway.doprivate final String GATEWAY_URL ="https://openapi.alipaydev.com/gateway.do";private final String FORMAT = "JSON";//签名方式private final String SIGN_TYPE = "RSA2";//支付宝异步通知路径,付款完毕后会异步调用本项目的方法,必须为公网地址private final String NOTIFY_URL = "http://公网地址/notifyUrl";//支付宝同步通知路径,也就是当付款完毕后跳转本项目的页面,可以不是公网地址private final String RETURN_URL = "http://公网地址/returnUrl";}

创建调用支付宝支付的方法

  @RequestMapping("alipay")public void alipay(HttpServletResponse httpResponse) throws IOException {Random r=new Random();//实例化客户端,填入所需参数AlipayClient alipayClient = new DefaultAlipayClient(GATEWAY_URL, APP_ID, APP_PRIVATE_KEY, FORMAT, CHARSET, ALIPAY_PUBLIC_KEY, SIGN_TYPE);AlipayTradePagePayRequest request = new AlipayTradePagePayRequest();//在公共参数中设置回跳和通知地址request.setReturnUrl(RETURN_URL);request.setNotifyUrl(NOTIFY_URL);//商户订单号，商户网站订单系统中唯一订单号，必填//生成随机IdString out_trade_no = UUID.randomUUID().toString();//付款金额，必填String total_amount =Integer.toString(r.nextInt(9999999)+1000000);//订单名称，必填String subject ="奥迪A8 2016款 A8L 60 TFSl quattro豪华型";//商品描述，可空String body = "尊敬的会员欢迎购买奥迪A8 2016款 A8L 60 TFSl quattro豪华型";request.setBizContent("{\"out_trade_no\":\""+ out_trade_no +"\","+ "\"total_amount\":\""+ total_amount +"\","+ "\"subject\":\""+ subject +"\","+ "\"body\":\""+ body +"\","+ "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");String form = "";try {form = alipayClient.pageExecute(request).getBody(); // 调用SDK生成表单} catch (AlipayApiException e) {e.printStackTrace();}httpResponse.setContentType("text/html;charset=" + CHARSET);httpResponse.getWriter().write(form);// 直接将完整的表单html输出到页面httpResponse.getWriter().flush();httpResponse.getWriter().close();}
}

测试需要下载沙箱支付宝（下载二维码）这个下载只对安卓手机（苹果不行）

接下来启动项目就访问我们的方法了访问xxxx.do就可直接跳到支付页面

在付款成功后,浏览器会跳转到我们定义的同步回调页面,来验证是否付款成功等操作

@RequestMapping(value = "/returnUrl", method = RequestMethod.GET)
public String returnUrl(HttpServletRequest request, HttpServletResponse response)throws IOException, AlipayApiException {System.out.println("=================================同步回调=====================================");// 获取支付宝GET过来反馈信息Map<String, String> params = new HashMap<String, String>();Map<String, String[]> requestParams = request.getParameterMap();for (Iterator<String> iter = requestParams.keySet().iterator(); iter.hasNext();) {String name = (String) iter.next();String[] values = (String[]) requestParams.get(name);String valueStr = "";for (int i = 0; i < values.length; i++) {valueStr = (i == values.length - 1) ? valueStr + values[i] : valueStr + values[i] + ",";}// 乱码解决，这段代码在出现乱码时使用valueStr = new String(valueStr.getBytes("utf-8"), "utf-8");params.put(name, valueStr);}System.out.println(params);//查看参数都有哪些boolean signVerified = AlipaySignature.rsaCheckV1(params, ALIPAY_PUBLIC_KEY, CHARSET, SIGN_TYPE); // 调用SDK验证签名//验证签名通过if(signVerified){// 商户订单号String out_trade_no = new String(request.getParameter("out_trade_no").getBytes("ISO-8859-1"), "UTF-8");// 支付宝交易号String trade_no = new String(request.getParameter("trade_no").getBytes("ISO-8859-1"), "UTF-8");// 付款金额String total_amount = new String(request.getParameter("total_amount").getBytes("ISO-8859-1"), "UTF-8");System.out.println("商户订单号="+out_trade_no);System.out.println("支付宝交易号="+trade_no);System.out.println("付款金额="+total_amount);//支付成功，修复支付状态payService.updateById(Integer.valueOf(out_trade_no));return "ok";//跳转付款成功页面}else{return "no";//跳转付款失败页面}}

上面为支付宝同步调用处理,但是官方建议应在异步调用方法中处理付款成功后的操作,但因异步调用的路径必须为公网地址,支付宝才可以发送请求给我们,故这里不写异步调用的方法了,需要注意的是,异步调用为post请求,且传递来的参数会多一些,但基本与同步调用的操作一致,下面为支付宝官方调用图解

沙箱有商家和买家你一看就懂！！！！

拿去装13去吧！！！！！！！

又不要真给我付点
自己看着办吧
