支付宝手机网站支付(基于Java实现支付宝手机网站支付)

支付宝支付核心需要的参数是(APPID，PRIVATE_KEY，ALIPAY_PUBLIC_KEY)APPID：创建应用后就有的APPID。PRIVATE_KEY：应用私钥ALIPAY_PUBLIC_KEY：支付宝公钥上面的2，3的参数得自己弄到，参考文档：https://docs./291/105971/下载好工具后所需要干的事情：（获取到的应用公钥配置到：蚂蚁金服开放平台中在 “应用信息” - “开发设置” - “加签方式”处点击 “设置应用公钥”。获取到的应用私钥就是：PRIVATE_KEY。支付宝公钥ALIPAY_PUBLIC_KEY：当设置应用公钥完成后就可以查看支付宝公钥内容。）配置Maven依赖：/artifact/com.alipay.sdk/alipay-sdk-java

配置支付所需配置文件

/*** 支付宝支付配置文件*/public class AlipayConfig {// 1.商户创建应用后获取的appidpublic static String APPID = "********";// 2.应用私钥public static String PRIVATE_KEY ="*******";// 3.支付宝公钥public static String ALIPAY_PUBLIC_KEY = "******";// 4.回调接口全路径(支付完成异步通知)public static String notify_url = "https://******";// 5.页面跳转同步通知页面路径(支付完成后跳转的页面) public static String return_url = "https://******";// 6.请求支付宝的网关地址public static String URL = "/gateway.do";// 7.编码public static String CHARSET = "UTF-8";// 8.返回格式public static String FORMAT = "json";// 9.加密类型public static String SIGNTYPE = "RSA2";}

业务层预下单

控制层下单接口以及回调接口

import com.mon.wx.XMLUtils;import com.aone.app.service.AliH5PayService;import io.swagger.annotations.Api;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.util.StringUtils;import org.springframework.web.bind.annotation.*;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import java.io.BufferedReader;import java.util.HashMap;import java.util.Map;@RestController@RequestMapping("h5pay")@Api("H5支付")public class PayH5Controller {private static final Logger log = LoggerFactory.getLogger("PayH5Controller");@Autowiredprivate AliH5PayService aliH5PayService;/*** H5支付统一下单* @param request* @return* @throws Exception*/@ResponseBody@RequestMapping(value = "wxPay")public Map<String, String> weixinPay(HttpServletRequest request) throws Exception{String type= request.getParameter("type");String orderNo= request.getParameter("orderNo");String money= request.getParameter("money");return aliH5PayService.dounifiedOrder(type,orderNo,money,request);}/*** H5微信支付异步结果通知* @param request* @param response* @throws Exception*/@RequestMapping(value = "notify")public void weixinPayNotify(HttpServletRequest request, HttpServletResponse response) throws Exception {BufferedReader reader = request.getReader();String line = "";Map map = new HashMap();String xml = "<xml><return_code><![CDATA[FAIL]]></xml>";;StringBuffer inputString = new StringBuffer();while ((line = reader.readLine()) != null) {inputString.append(line);}request.getReader().close();log.error("----接收到的报文---{}",inputString.toString());if(inputString.toString().length()>0){map = XMLUtils.parseXmlToList(inputString.toString());}else{log.error("接受微信报文为空");}log.error("map={}",map);if(map!=null && "SUCCESS".equals(map.get("result_code"))){//成功的业务。。。xml = "<xml><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg></xml>";String type=map.get("attach").toString();String orderNo=map.get("out_trade_no").toString();log.error("订单号{}",map.get("out_trade_no"));log.error("其它必须参数{}",map.get("attach"));if(StringUtils.isEmpty(type)||StringUtils.isEmpty(orderNo)){log.error("当前参数类型异常");}else{//回调业务逻辑}}else{//失败的业务。。。 }//告诉微信端已经确认支付成功 response.getWriter().write(xml);}}

回调接口中解析微信通知XML的工具类XMLUtils，参考微信H5支付，缺少其它东西也可参考其它记录。
