一、前言
二、支付宝沙箱环境集成Web项目
1、将支付宝Demo中的相关文件复制到我们的项目中
1.1 Maven以外的Jar包（红框部分）（主要2个，还有2个是对应的源码）
1.2 Maven以内的Jar包（最好版本号都一样，以免出现意想不到的事）
<!-- alipay --> <dependencies> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.10</version> </dependency> <dependency> <groupId>commons-configuration</groupId> <artifactId>commons-configuration</artifactId> <version>1.10</version> </dependency> <dependency> <groupId>commons-lang</groupId> <artifactId>commons-lang</artifactId> <version>2.6</version> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>com.google.zxing</groupId> <artifactId>core</artifactId> <version>2.1</version> </dependency> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>2.3.1</version> </dependency> <dependency> <groupId>org.hamcrest</groupId> <artifactId>hamcrest-core</artifactId> <version>1.3</version> </dependency> </dependencies>
1.3 上面是jar包的配置，接下来我们在pom.xml里面配置一个插件，使项目编译需要的jar在项目部署的时候自动将 lib 包里的Jar添加到项目依赖中
<!-- geelynote maven的核心插件之-complier插件默认只支持编译Java 1.4，因此需要加上支持高版本jre的配置，在pom.xml里面加上 增加编译插件 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.7</source> <target>1.7</target> <encoding>UTF-8</encoding> <compilerArguments> <extdirs>${project.basedir}/src/main/webapp/WEB-INF/lib</extdirs> </compilerArguments> </configuration> </plugin>
1.4 zhifubao.properties这个配置文件方法我们项目中的 resources目录下

1.5 继而我们运行一下复制过来的Main.class，发现Demo是可以跑起来的~
2、编写支付接口
2.1 OrderController类
@Controller @RequestMapping("/order/") public class OrderController { private static final Logger logger = LoggerFactory.getLogger(OrderController.class); @RequestMapping("pay.do") @ResponseBody public ServerResponse pay(HttpSession session, Long orderNo, HttpServletRequest request){ User user = (User)session.getAttribute(Const.CURRENT_USER); if(user == null){ return ServerResponse.createByErrorCodeMessage(ResponseCode.NEED_LOGIN.getCode(),ResponseCode.NEED_LOGIN.getDesc()); } String path = request.getSession().getServletContext().getRealPath("upload"); return iOrderService.pay(orderNo,user.getId(),path); } @RequestMapping("alipay_callback.do") @ResponseBody public Object alipayCallback(HttpServletRequest request){ // 回调函数，也就是在支付成功之后，可以调用我们支付之后需要执行的相关方法，从而达到数据库的数据和我们的操作相统一。 Map<String,String> params = Maps.newHashMap(); 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]+","; } params.put(name,valueStr); } logger.info("支付宝回调,sign:{},trade_status:{},参数:{}",params.get("sign"),params.get("trade_status"),params.toString()); // 非常重要，验证回调的正确性，是不是支付宝发的。并且呢还要避免重复通知。 params.remove("sign_type"); // 因为支付宝要求我们除去两个参数 sign（rsaCheckV2函数已经帮我们除去）、sign_type（自己手动除去） try { // RSA2 // 第二参数注意是支付宝公共密钥，而不是应用密钥 // 这里编码是与 new AlipayTradeServiceImpl.ClientBuilder().build(); 里的编码一样，build() 默认为UTF-8，当然也可以自定义，但是只要保证两个一样即可，我们统一保持UTF-8 boolean alipayRSACheckedV2 = AlipaySignature.rsaCheckV2(params, Configs.getAlipayPublicKey(),"utf-8",Configs.getSignType()); if(!alipayRSACheckedV2){ return ServerResponse.createByErrorMessage("非法请求,验证不通过,再恶意请求我就报警找网警了"); } } catch (AlipayApiException e) { logger.error("支付宝验证回调异常",e); } /* todo 验证各种数据 第五步：需要严格按照如下描述校验通知数据的正确性。 商户需要验证该通知数据中的out_trade_no是否为商户系统中创建的订单号， 并判断total_amount是否确实为该订单的实际金额（即商户订单创建时的金额）， 同时需要校验通知中的seller_id（或者seller_email）是否为out_trade_no这笔单据的对应的操作方（有的时候，一个商户可能有多个seller_id/seller_email）， 上述有任何一个验证不通过，则表明本次通知是异常通知，务必忽略。 在上述验证通过后商户必须根据支付宝不同类型的业务通知，正确的进行不同的业务处理，并且过滤重复的通知结果数据。 在支付宝的业务通知中，只有交易通知状态为TRADE_SUCCESS或TRADE_FINISHED时，支付宝才会认定为买家付款成功。 */ ServerResponse serverResponse = iOrderService.aliCallback(params); if(serverResponse.isSuccess()){ return Const.AlipayCallback.RESPONSE_SUCCESS; } return Const.AlipayCallback.RESPONSE_FAILED; } @RequestMapping("query_order_pay_status.do") @ResponseBody public ServerResponse<Boolean> queryOrderPayStatus(HttpSession session, Long orderNo){ User user = (User)session.getAttribute(Const.CURRENT_USER); if(user ==null){ return ServerResponse.createByErrorCodeMessage(ResponseCode.NEED_LOGIN.getCode(),ResponseCode.NEED_LOGIN.getDesc()); } ServerResponse serverResponse = iOrderService.queryOrderPayStatus(user.getId(),orderNo); if(serverResponse.isSuccess()){ return ServerResponse.createBySuccess(true); } return ServerResponse.createBySuccess(false); } }
2.2 IOrderService接口类
package com.mmall.service; import com.github.pagehelper.PageInfo; import com.mmall.common.ServerResponse; import com.mmall.vo.OrderVo; import java.util.Map; public interface IOrderService { ServerResponse pay(Long orderNo, Integer userId, String path); ServerResponse aliCallback(Map<String,String> params); ServerResponse queryOrderPayStatus(Integer userId,Long orderNo); }

goodsDetailList.add(goods); } // 创建扫码支付请求builder，设置请求参数 AlipayTradePrecreateRequestBuilder builder = new AlipayTradePrecreateRequestBuilder() .setSubject(subject).setTotalAmount(totalAmount).setOutTradeNo(outTradeNo) .setUndiscountableAmount(undiscountableAmount).setSellerId(sellerId).setBody(body) .setOperatorId(operatorId).setStoreId(storeId).setExtendParams(extendParams) .setTimeoutExpress(timeoutExpress) .setNotifyUrl(PropertiesUtil.getProperty("alipay.callback.url")) // 支付宝服务器主动通知商户服务器里指定的页面http路径,根据需要设置 .setGoodsDetailList(goodsDetailList); AlipayF2FPrecreateResult result = tradeService.tradePrecreate(builder); switch (result.getTradeStatus()) { case SUCCESS: logger.info("支付宝预下单成功: )"); AlipayTradePrecreateResponse response = result.getResponse(); dumpResponse(response); File folder = new File(path); if(!folder.exists()){ folder.setWritable(true); folder.mkdirs(); } // 生成支付二维码 // 需要修改为运行机器上的路径 // 细节细节细节，别忘了“/” String qrPath = String.format(path+"/qr-%s.png",response.getOutTradeNo());

} catch (IOException e) { logger.error("上传二维码异常",e); } logger.info("qrPath:" + qrPath); String qrUrl = PropertiesUtil.getProperty("ftp.server.http.prefix")+targetFile.getName(); resultMap.put("qrUrl",qrUrl); return ServerResponse.createBySuccess(resultMap); case FAILED: logger.error("支付宝预下单失败!!!"); return ServerResponse.createByErrorMessage("支付宝预下单失败!!!"); case UNKNOWN: logger.error("系统异常，预下单状态未知!!!"); return ServerResponse.createByErrorMessage("系统异常，预下单状态未知!!!"); default: logger.error("不支持的交易状态，交易返回异常!!!"); return ServerResponse.createByErrorMessage("不支持的交易状态，交易返回异常!!!"); } } // 简单打印应答 private void dumpResponse(AlipayResponse response) { if (response != null) { logger.info(String.format("code:%s, msg:%s", response.getCode(), response.getMsg()));

String tradeNo = params.get("trade_no"); String tradeStatus = params.get("trade_status"); Order order = orderMapper.selectByOrderNo(orderNo); if(order == null){ return ServerResponse.createByErrorMessage("非快乐慕商城的订单,回调忽略"); } if(order.getStatus() >= Const.OrderStatusEnum.PAID.getCode()){ return ServerResponse.createBySuccess("支付宝重复调用"); } if(Const.AlipayCallback.TRADE_STATUS_TRADE_SUCCESS.equals(tradeStatus)){ order.setPaymentTime(DateTimeUtil.strToDate(params.get("gmt_payment"))); order.setStatus(Const.OrderStatusEnum.PAID.getCode()); orderMapper.updateByPrimaryKeySelective(order); } PayInfo payInfo = new PayInfo(); payInfo.setUserId(order.getUserId()); payInfo.setOrderNo(order.getOrderNo()); payInfo.setPayPlatform(Const.PayPlatformEnum.ALIPAY.getCode()); payInfo.setPlatformNumber(tradeNo); payInfo.setPlatformStatus(tradeStatus); payInfoMapper.insert(payInfo); return ServerResponse.createBySuccess(); } // 查询订单支付状态 public ServerResponse queryOrderPayStatus(Integer userId,Long orderNo){ Order order = orderMapper.selectByUserIdAndOrderNo(userId,orderNo); if(order == null){ return ServerResponse.createByErrorMessage("用户没有该订单"); } if(order.getStatus() >= Const.OrderStatusEnum.PAID.getCode()){ return ServerResponse.createBySuccess(); } return ServerResponse.createByError(); } }
我们会发现，上面的大多数是直接从支付宝Demo中的Main类中复制过来的，我们只是更改了对应的参数。上面第四行代码我们用到了自己封装了一个根据订单号和用户Id来查询订单的方法。
2.4 *Mapper
//根据订单号和用户的Id来查询订单 Order selectByUserIdAndOrderNo(@Param("userId") Integer userId,@Param("orderNo") Long orderNo); //根据订单号来查询订单是否存在 Order selectByOrderNo(Long orderNo);
2.5 *Mapper.xml
<select id="selectByUserIdAndOrderNo" parameterType="map" resultMap="BaseResultMap"> select <include refid="Base_Column_List"/> from mmall_order where order_no = #{orderNo} and user_id = #{userId} </select> <select id="selectByOrderNo" resultMap="BaseResultMap" parameterType="long" > select <include refid="Base_Column_List"/> from mmall_order where order_no=#{orderNo} </select>
2.6 Const类
public enum OrderStatusEnum{ CANCELED(0,"已取消"), NO_PAY(10,"未支付"), PAID(20,"已付款"), SHIPPED(40,"已发货"), ORDER_SUCCESS(50,"订单完成"), ORDER_CLOSE(60,"订单关闭"); OrderStatusEnum(int code,String value){ this.code = code; this.value = value; } private String value; private int code; public String getValue() { return value; } public int getCode() { return code; } public static OrderStatusEnum codeOf(int code){ for(OrderStatusEnum orderStatusEnum : values()){ if(orderStatusEnum.getCode() == code){ return orderStatusEnum; } } throw new RuntimeException("么有找到对应的枚举"); } } public interface AlipayCallback{ String TRADE_STATUS_WAIT_BUYER_PAY = "WAIT_BUYER_PAY"; String TRADE_STATUS_TRADE_SUCCESS = "TRADE_SUCCESS"; String RESPONSE_SUCCESS = "success"; String RESPONSE_FAILED = "failed"; } public enum PayPlatformEnum{ ALIPAY(1,"支付宝"); PayPlatformEnum(int code,String value){ this.code = code; this.value = value; } private String value; private int code; public String getValue() { return value; } public int getCode() { return code; } } public enum PaymentTypeEnum{ ONLINE_PAY(1,"在线支付"); PaymentTypeEnum(int code,String value){ this.code = code; this.value = value; } private String value; private int code; public String getValue() { return value; } public int getCode() { return code; } public static PaymentTypeEnum codeOf(int code){ for(PaymentTypeEnum paymentTypeEnum : values()){ if(paymentTypeEnum.getCode() == code){ return paymentTypeEnum; } } throw new RuntimeException("么有找到对应的枚举"); } }
