AliPay - Java支付宝接口开发（三）

一、前言

AliPay - Java支付宝接口开发（一）

AliPay - Java支付宝接口开发（二）

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")@ResponseBodypublic 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")@ResponseBodypublic 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-8boolean 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")@ResponseBodypublic 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);
}

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

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_orderwhere order_no = #{orderNo}and user_id = #{userId}
</select><select id="selectByOrderNo" resultMap="BaseResultMap" parameterType="long" >select<include refid="Base_Column_List"/>from mmall_orderwhere  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");}
}

3、支付接口测试（一）

打开地址，显示二维码。

4、支付接口测试（二）

给沙箱环境配置我们的回调地址。

打开沙箱环境：登录 - 支付宝

在图上所示配置我们的回调地址。

由于我们是在本地开发，所以需要将本地IP映射到公网，这个教程有讲怎么将本地IP映射到公网：https://blog.csdn.net/czjlghndcy/article/details/81130029

映射好公网IP之后，我们就将对应生成的共网IP以及定义的接口访问地址粘贴到沙箱环境中的回调地址中即可~

支付一个未支付的案例

对生成的二维码进行支付

查询订单状态

显示已支付，So，我们的回调接口以及订单状态查询接口测试成功啦~
