- 在配置文件配置私钥，支付宝公钥（注意不是支付宝应用公钥）
alipay: appid: XXXXXXXXXXXXX gatewayUrl: https://openapi.alipay.com/gateway.do （正式环境网关，若用沙箱环境，需要更改） format: json charset: utf-8 signType: RSA2 returnUrl: http://XXXXXXXXXXXXXXXX/alipay/return（同步回调，不需要配置，只要路径正确，本地可以访问即可） notifyUrl: http://XXXXXXXXXXXXX/alipay/notify（异步回调，需要在支付宝上配置路径，外网可访问） app-private-key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX alipay-public-key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 1234567891011
- 支付宝配置类
@Component
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
@Value("${alipay.appid}")
public String app_id;
// 商户私钥，您的PKCS8格式RSA2私钥
@Value("${alipay.app-private-key}")
public String merchant_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。
@Value("${alipay.alipay-public-key}")
public String alipay_public_key;
// 服务器异步通知页面路径 需http://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问
//public static String notify_url = "http://工程公网访问地址/alipay.trade.page.pay-JAVA-UTF-8/notify_url.jsp";
@Value("${alipay.notifyUrl}")
public 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 = "http://工程公网访问地址/alipay.trade.page.pay-JAVA-UTF-8/return_url.jsp";
@Value("${alipay.returnUrl}")
public String return_url ;
// 签名方式
@Value("${alipay.signType}")
public String sign_type;
// 字符编码格式
@Value("${alipay.charset}")
public String charset;
// 支付宝网关
@Value("${alipay.gatewayUrl}")
public String gatewayUrl;
@Value("${alipay.format}")
public String format;
// 支付宝网关
@Value("${alipay.logs}")
public static String log_path;
//↑↑↑↑↑↑↑↑↑↑请在这里配置您的基本信息↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑
public static void logResult(String sWord) {
FileWriter writer = null;
try {
writer = new FileWriter(log_path + "alipay_log_" + System.currentTimeMillis()+".txt");
writer.write(sWord);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (writer != null) {
try {
writer.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}

生成支付宝支付二维码：
@PostMapping("/gotoPayPage")
@ResponseBody
public void gotoPayPage(){
AlipayTradePagePayRequest pagePayRequest=new AlipayTradePagePayRequest();
//SDK 公共请求类，包含公共请求参数，以及封装了签名与验签，开发者无需签名与验签
AlipayClient alipayClient = new DefaultAlipayClient(alipayConfig.gatewayUrl,alipayConfig.app_id,alipayConfig.merchant_private_key, alipayConfig.format,
alipayConfig.charset, alipayConfig.alipay_public_key, alipayConfig.sign_type);
pagePayRequest.setReturnUrl(alipayConfig.return_url);
pagePayRequest.setNotifyUrl(alipayConfig.notify_url);
// 订单模型
String productCode = "FAST_INSTANT_TRADE_PAY";
//商户订单号
String orderNo = “订单号”;
//付款金额
String totalFee = “付款金额，以元为单位”;
//订单名称
String subject = "456";
//商品描述
String body = "123";
AlipayTradePayModel model = new AlipayTradePayModel();
model.setOutTradeNo(orderNo);
model.setProductCode(productCode);
model.setTotalAmount(totalFee);
model.setSubject("subject");
// model.setBody("body");
pagePayRequest.setBizModel(model);
//请求
String form = "";
try {
//String result = alipayClient.pageExecute(pagePayRequest).getBody();
AlipayTradePagePayResponse payResponse = alipayClient.pageExecute(pagePayRequest);
form = payResponse.getBody();
response.setContentType("text/html;charset="+alipayConfig.charset);
response.getWriter().write(form);
response.getWriter().flush();
response.getWriter().close();
}catch (Exception e){
e.printStackTrace();
throw new RuntimeException("支付宝二维码数据生成失败");
}
}
2、支付宝同步回调方法
@GetMapping("/return")
public String returnCallback(HttpServletRequest request, HttpServletResponse response){
System.out.println("**************************同步回调方法执行*******************************************");
//获取支付宝GET过来反馈信息
Map<String,String> params = new HashMap<String,String>();
Map requestParams = request.getParameterMap();
try {
for (Iterator 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。如果mysign和sign不相等也可以使用这段代码转化
valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8");
params.put(name, valueStr);
}
System.out.println("params---------->"+params);
//调用SDK验证签名
boolean signVerified = AlipaySignature.rsaCheckV1(params,alipayConfig.alipay_public_key, alipayConfig.charset, alipayConfig.sign_type);
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");
//TODO 将支付宝返回的数据记录到数据库中
//1、根据订单号查询订单是否存在，
//2、根据支付宝返回的trade_status状态进行下一步要操作，成功：更新订单状态，
//response.getWriter().write("success");
return "success";
}else {
return "fail";
// response.getWriter().write("fail");
}
}catch (Exception e){
e.printStackTrace();
throw new RuntimeException("回调异常");
}
}
3、异步回调
@PostMapping("/notify")
@ResponseBody
public String notifyUrl(HttpServletRequest request,HttpServletResponse response){
//获取支付宝POST过来反馈信息
Map<String,String> params = new HashMap<String,String>();
Map<String,String[]> requestParams = request.getParameterMap();
try {
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("ISO-8859-1"), "utf-8");
params.put(name, valueStr);
}
System.out.println("支付宝支付返回参数params-------->"+params);
boolean signVerified = AlipaySignature.rsaCheckV1(params, alipayConfig.alipay_public_key, alipayConfig.charset, alipayConfig.sign_type); //调用SDK验证签名
System.out.println("signVerified----->"+signVerified);
PrintWriter out = null;
if (signVerified){
//商户订单号 orderNo
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");
//买家支付宝交易账号
String buyer_id = new String(request.getParameter("buyer_id").getBytes("ISO-8859-1"),"UTF-8");
//交易总金额
String total_amount = new String(request.getParameter("total_amount").getBytes("ISO-8859-1"),"UTF-8");
//实收金额
String receipt_amount = new String(request.getParameter("receipt_amount").getBytes("ISO-8859-1"),"UTF-8");
//付款金额
String buyer_pay_amount = new String(request.getParameter("buyer_pay_amount").getBytes("ISO-8859-1"),"UTF-8");
//交易时间
String gmt_create = new String(request.getParameter("gmt_create").getBytes("ISO-8859-1"),"UTF-8");
//交易付款时间
String gmt_payment = new String(request.getParameter("gmt_payment").getBytes("ISO-8859-1"),"UTF-8");
//获取appid
String app_id = new String(request.getParameter("app_id").getBytes("ISO-8859-1"),"UTF-8");
//交易状态
String trade_status = new String(request.getParameter("trade_status").getBytes("ISO-8859-1"),"UTF-8");
//根据订单查询该订单是否存在
if (memberOrder == null){
throw new AlipayApiException("out_trade_no错误");
}
//判断支付金额是否正确
if (!total_amount.equals(memberOrder.getTotalFee().toString())){
throw new AlipayApiException("error total_amount");
}
//判断appid是否一致
if (!app_id.equals(alipayConfig.app_id)){
throw new AlipayApiException("app_id不一致");
}
System.out.println("trade_status------------>"+trade_status);
if(trade_status.equals("TRADE_FINISHED")){
//判断该笔订单是否在商户网站中已经做过处理
//如果没有做过处理，根据订单号（out_trade_no）在商户网站的订单系统中查到该笔订单的详细，并执行商户的业务程序
//如果有做过处理，不执行商户的业务程序
//注意：
//退款日期超过可退款期限后（如三个月可退款），支付宝系统发送该交易状态通知
}else if (trade_status.equals("TRADE_SUCCESS")){//向支付宝订单记录表中添加数据
//判断该笔订单是否在商户网站中已经做过处理
//如果没有做过处理，根据订单号（out_trade_no）在商户网站的订单系统中查到该笔订单的详细，并执行商户的业务程序
//如果有做过处理，不执行商户的业务程序
//注意：
//付款完成后，支付宝系统发送该交易状态通知
}
//response.getOutputStream().print("success");
return "success";
//
}else {//验签失败
// response.getOutputStream().print("failure");
return "failure";
}
}catch (AlipayApiException e) {
System.out.println(e.getErrMsg());
throw new RuntimeException("调用支付宝接口发生异常");
} catch (UnsupportedEncodingException e) {
System.out.println(e.getMessage());
throw new RuntimeException("URLDecoderf发生异常");
}
}
4、订单查询
@GetMapping("/query")
@ResponseBody
public String query(String orderNo, String tradeNo){
if (StringUtils.isBlank(orderNo)){
throw new RuntimeException("订单号不能为空");
}
//SDK 公共请求类，包含公共请求参数，以及封装了签名与验签，开发者无需签名与验签
AlipayClient alipayClient = new DefaultAlipayClient(alipayConfig.gatewayUrl,alipayConfig.app_id,alipayConfig.merchant_private_key, alipayConfig.format,
alipayConfig.charset, alipayConfig.alipay_public_key, alipayConfig.sign_type);
AlipayTradeQueryRequest alipay_request = new AlipayTradeQueryRequest();
AlipayTradeQueryModel model=new AlipayTradeQueryModel();
model.setOutTradeNo(orderNo);
model.setTradeNo(tradeNo);
alipay_request.setBizModel(model);
String form = "";
try {
AlipayTradeQueryResponse alipay_response =alipayClient.execute(alipay_request);
form = alipay_response.getBody();
System.out.println("form----->"+form);
return form;
}catch (AlipayApiException e){
e.printStackTrace();
throw new RuntimeException("支付宝查询交易数据失败");
}
}

注意：要对异步回调、同步回调、查询放行，不要拦截
