注意：
1.回调接口中，produces类型很重要
2.@ApiOperation/@ApiParam为swagger注解
3.支付宝配置中
privateKey为应用私钥，即使用支付宝工具生成的私钥，取pkcs8.pem结尾的文件中的值
publicKey为支付宝公钥，此处应区分与应用私钥的区别，在开放平台-密钥管理-查看支付宝公钥
两个接口：
1.生成支付单接口（返回给前端拉起支付宝）
controller示例：
@RequestMapping(value ="/payorder/for/{billNo}",method = RequestMethod.GET,produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
@ResponseBody
@ApiOperation(value ="获取支付单",httpMethod ="GET",response = AlipayTradeAppPayResponse.class)
public JsonResultResponsegetPayOrder(@ApiParam(name ="billNo",value ="billNo")@PathVariable String billNo,
HttpServletRequest request){
String userId = request.getHeader(HTTP_HEAD_KEY);
return JsonResultResponse.buildJsonResultResponse(alipayService.getPayOrder(billNo,userId));
}
service示例
//构建支付订单
AlipayClient alipayClient =new DefaultAlipayClient(AlipayConfig.ALI_OPEN_API_GATEWAY, AlipayConfig.appid,AlipayConfig.privatekey,
AlipayConfig.format,AlipayConfig.charset,AlipayConfig.publickey, AlipayConfig.signType);
AlipayTradeAppPayRequest request =new AlipayTradeAppPayRequest();
AlipayTradeAppPayModel model =new AlipayTradeAppPayModel();
//RMB分转元
BigDecimal paiedAmt = RMBCentToDollar(getPaid(tradeOrderVo.getTotalAmount(),tradeOrderVo.getDiscountAmount()));
model.setSubject("支付宝支付");
model.setOutTradeNo(billNo);
model.setTimeoutExpress("30m");
model.setTotalAmount(paiedAmt.toString()); //单位为yuan
//model.setProductCode();
request.setBizModel(model);
request.setNotifyUrl(AlipayConfig.notifyurl);
AlipayTradeAppPayResponse response = alipayClient.sdkExecute(request);
2.支付宝回调接口：
controller示例
@RequestMapping(value ="/notify",method = RequestMethod.POST,produces = MediaType.TEXT_PLAIN_VALUE)
@ResponseBody
@ApiOperation(value ="支付宝回调",httpMethod ="POST")
public StringaliNotify(HttpServletRequest request){
try {
return alipayService.aliNotify(request);
}catch (AlipayApiException e) {
logger.error(e.getMessage(),e);
return e.getMessage();
}catch (UnsupportedEncodingException e) {
logger.error(e.getMessage(),e);
return e.getMessage();
}
}
service示例
public StringaliNotify(HttpServletRequest request)throws AlipayApiException, UnsupportedEncodingException {
//获取参数
Map requestParams = request.getParameterMap();
logger.info("aliNotify request parameterMap: [{}]",JsonUtils.toJSON(requestParams));
Map params =new HashMap<>();
for (Iterator iterator = requestParams.keySet().iterator(); iterator.hasNext(); ) {
String name = (String) iterator.next();
String[] valueArray = (String[]) requestParams.get(name);
String values ="";
for (int i =0; i < valueArray.length; i++) {
values = (i == valueArray.length -1) ? values + valueArray[i]
: values + valueArray[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
// values = new String(values.getBytes("ISO-8859-1"), "gbk");
params.put(name, values);
}
logger.info("aliNotify request params:[{}]", JSONUtils.toJSONString(params));
boolean flag = AlipaySignature.rsaCheckV1(params, AlipayConfig.publickey, AlipayConfig.charset, AlipayConfig.signType);
logger.info("ali pay check signature :flag [{}]",flag);
if(!flag) {
logger.error("invalid signature");
return FAIL;
}
//业务处理
return SUCCESS;
}
3:附-支付结果查询接口
controller:
@RequestMapping(value ="/resultquery",method = RequestMethod.GET,produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
@ResponseBody
@ApiOperation(value ="支付结果查询",httpMethod ="GET",response = PaymentPo.class)
public JsonResultResponsequeryPayResult(@ApiParam(name ="billNo",value ="billNo")@RequestParam String billNo,
HttpServletRequest request){
return JsonResultResponse.buildJsonResultResponse(alipayService.queryPayResult(billNo));
}
service:
//主动查询订单状态
AlipayClient alipayClient =new DefaultAlipayClient(AlipayConfig.ALI_OPEN_API_GATEWAY, AlipayConfig.appid,AlipayConfig.privatekey,
AlipayConfig.format,AlipayConfig.charset,AlipayConfig.publickey, AlipayConfig.signType);
AlipayTradeQueryRequest request =new AlipayTradeQueryRequest();
AlipayTradeQueryModel model =new AlipayTradeQueryModel();
model.setOutTradeNo(billNo);
request.setBizModel(model);
AlipayTradeQueryResponse response = alipayClient.execute(request);
logger.info("alipapy query order response:[{}]",response);
if(!response.isSuccess()){
logger.error("alipay query order response error. response code:[{}] msg:[{}]",response.getCode(),response.getMsg());
throw new Exception("alipay query order response error");
}
//交易状态：WAIT_BUYER_PAY（交易创建，等待买家付款）、TRADE_CLOSED（未付款交易超时关闭，或支付完成后全额退款）、TRADE_SUCCESS（交易支付成功）、TRADE_FINISHED（交易结束，不可退款）
String tradeStatus = response.getTradeStatus().toUpperCase();
//业务处理
