支付宝和微信APP支付 java服务端代码
支付宝和微信支付的接入基本只需要看官方文档就能很好的弄明白，这里我做记录一些我在接入是写demo
首先需要创建一个配置管理的类：
public final class ZhifubaoConfig {
/**
* 应用号
*/
public static String APP_ID = "2018080360956028";
/**
* 商户的私钥
*/
public static String APP_PRIVATE_KEY = ""; //这是在支付宝给的秘钥生成器 生成的私钥 用于用户加签
/**
*
* 编码
*/
public static String CHARSET = "UTF-8";
/**
* 支付宝公钥
*/
public static String ALIPAY_PUBLIC_KEY = " "; //这是支付宝平台的分配的支付公钥，主要用于验签支付宝平台返回给商户的信息， 这里需要特别主要的是要区分清楚 支付宝公钥 和 商户公钥的不同，商户公钥是用户自己生成的，需要上传至支付宝平台。
/**
* 支付宝网关地址
*/
private static String GATEWAY = "https://openapi.alipay.com/gateway.do";
/**
* 成功付款回调
*/
public static String PAY_NOTIFY = ""; // 商户的回调地址
/**
* 参数类型
*/
public static String PARAM_TYPE = "json";
/**
* 成功标识
*/
public static final String SUCCESS_REQUEST = "TRADE_SUCCESS";
/**
* 交易关闭回调(当该笔订单全部退款完毕,则交易关闭)
*/
public static final String TRADE_CLOSED = "TRADE_CLOSED";
/**
* 收款方账号
*/
public static final String SELLER_ID = ""; // 可以不用配置
/**
* 加密类型
*/
public static String SIGNTYPE = "RSA2";
/**
* 支付宝请求客户端入口
*/
private volatile static ZhifubaoConfig zhifubaoConfig= null;
/**
* 不可实例化
*/
private ZhifubaoConfig(){};
/**
* 双重锁单例
* @return 支付宝请求客户端实例
*/
public static ZhifubaoConfiggetInstance(){
if (alipayClient == null){
synchronized (AliPayConfig.class){
if (alipayClient == null){
zhifubaoConfig = new DefaultAlipayClient(GATEWAY,APP_ID,APP_PRIVATE_KEY,PARAM_TYPE,CHARSET,ALIPAY_PUBLIC_KEY,SIGNTYPE);
}
}
}
return alipayClient;
}2.我这边把调用支付宝的逻辑代码封装了一下
public class ZhifubaoTrade {
private Logger logger = LoggerFactory.getLogger(ZhifubaoTrade .class);
/**
* APP支付下单并支付(APP支付在安卓中是可以直接唤醒支付宝APP的)
* url
* @return App支付单
*/
public String TradeWapPayRequest(AlipayTradeAppPayModel model){
AlipayTradeAppPayRequest alipayRequest = new AlipayTradeAppPayRequest ();
alipayRequest.setReturnUrl(ZhifubaoConfig.RETURN_URL);
alipayRequest.setNotifyUrl(ZhifubaoConfig.PAY_NOTIFY);
alipayRequest.setBizModel(model);
String form = "";
try {
form = ZhifubaoConfig.getInstance().sdkExecute(alipayRequest).getBody();
System.err.println(form);
} catch (AlipayApiException e) {
logger.error("支付宝构造表单失败",e);
}
logger.debug("支付宝支付表单构造:"+form);
return form;
}
/**
* 申请退款
* @param sParaTemp 退款参数
* @return true成功,回调中处理
*/
public AlipayTradeRefundResponse tradeRefundRequest(Map sParaTemp) throws AlipayApiException {
AlipayTradeRefundRequest request = new AlipayTradeRefundRequest();
request.setReturnUrl(ZhifubaoConfig.RETURN_URL);
request.setNotifyUrl(ZhifubaoConfig.REFUND_NOTIFY);
// 待请求参数数组
request.setBizContent(JSON.toJSONString(sParaTemp));
AlipayTradeRefundResponse response = ZhifubaoConfig.getInstance().execute(request);
System.err.println(response.getBody());
return response;
}
/**
* 支付宝回调验签
* @param request 回调请求
* @return true成功
* 备注:验签成功后，按照支付结果异步通知中的描述(二次验签接口,貌似称为历史接口了)
*/
public boolean verifyNotify(HttpServletRequest request) throws AlipayApiException {
Map paranMap = SignUtil.request2Map(request);
logger.debug("支付宝回调参数:"+paranMap.toString());
boolean isVerify = false;
if (ZhifubaoConfig.SUCCESS_REQUEST.equals(paranMap.get("trade_status")) || ZhifubaoConfig.TRADE_CLOSED.equals(paranMap.get("trade_status"))) {
isVerify = AlipaySignature.rsaCheckV1(paranMap, ZhifubaoConfig.ALIPAY_PUBLIC_KEY, ZhifubaoConfig.CHARSET); //调用SDK验证签名
}
logger.debug("支付宝验签结果"+isVerify);
return isVerify;
}
/**
* 查询订单支付状态
* @param sParaTemp
* @return
* @throws AlipayApiException
*/
public Map searchBill(Map sParaTemp) throws AlipayApiException{
AlipayTradeQueryRequest request = new AlipayTradeQueryRequest();
request.setBizContent(JSON.toJSONString(sParaTemp));
AlipayTradeQueryResponse response = ZhifubaoConfig.getInstance().execute(request);
System.err.println(response.isSuccess());
System.err.println(response.getBody());
if(response.isSuccess()){
System.out.println("调用成功");
} else {
System.out.println("调用失败");
}
return null;
}
3 业务代码可以根据自己的需要组装，我这里贴一下我的
//-----------------支付相关--------------------------
int payType = Integer.valueOf(String.valueOf(data.get("payment_operation_way")));
Map paramMap = new HashMap<>();
paramMap.put("body", "时租看房");
paramMap.put("subject", "时租看房");
paramMap.put("code", code);
paramMap.put("amount", String.valueOf(data.get("amount")));
String resultStr = payMentService.doPay(payType, paramMap);
String payCode = "";
//创建支付订单
Map paymentM = new HashMap<>();
paymentM.put("trade_no", payCode);
paymentM.put("payment_operation_order_code", code);
paymentM.put("user_id", String.valueOf(data.get("user_id")));
paymentM.put("payment_operation_way", payType+"");
paymentM.put("payment_operation_type", "0");
paymentM.put("payment_operation_pay_way", "0");
paymentM.put("payment_amount", String.valueOf(data.get("amount")));
paymentM.put("status", "2");
paymentDao.createPaymentOperation(paymentM);
//预下单订单信息（返回给客户端）
map.put("payment_content", resultStr);
map.put("is_payment", "0");
//-----------------支付相关--------------------------
4 支付宝的部分回调代码
public String doCallback(HttpServletRequest request, HttpServletResponse reponse){
//获取支付宝POST过来反馈信息
String status = "";
Map params = new HashMap();
System.out.println("异步通知参数：");
Map requestParams = request.getParameterMap();
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] + ",";
}
if(name.equals("trade_status")){
status= valueStr;
System.out.println("交易状态为："+valueStr);
}
//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"), "gbk");
params.put(name, valueStr);
}
System.out.println("params"+params);
String pk = "自己的支付宝公钥";
//验签 如果成功则说明是来自支付宝的回调
// 处理回调业务 成功后给支付宝返回成功 详细的可以看官方文档
}
