|
||
# 1、背景说明
|
||
新入职的你加入了开发一组，也接到了开发任务，并且你也顺利的完成了网关的鉴权业务的开发。现在开发三组所负责的支付微服务需要你来支援一下，目前支付微服务完成了支付宝和微信的对接，主要实现的功能有支付渠道的维护、扫码支付（微信称Native支付，支付宝称当面付）、退款等功能。
|
||
其中扫码支付功能是快递员上门取件时，会亮出二维码，用户可以通过支付宝或微信进行扫描后，对运费的支付。
|
||
|
||
# 2、需求分析
|
||
## 2.1、整体流程
|
||
|
||
流程说明：
|
||
|
||
- 用户下单成功后，系统会为其分配快递员
|
||
- 快递员根据取件任务进行上门取件，与用户确认物品信息、重量、体积、运费等内容，确认无误后，取件成功
|
||
- 快递员会询问用户，是支付宝还是微信付款，根据用户的选择，展现支付二维码
|
||
- 用户使用手机，打开支付宝或微信进行扫描操作，用户进行付款操作，最终会有支付成功或失败情况
|
||
- 后续的逻辑暂时不考虑，支付微服务只考虑支付部分的逻辑即可
|
||
## 2.2、业务功能
|
||
 
|
||
## 2.3、产品需求
|
||
【付款方式】判断寄付/到付交互
|
||
|
||
1. 寄付→点击【取件】进入取件成功页面，点击左上方返回按钮返回待取件任务列表；点击【去收款】按钮进入扫码支付页面，此时用户有双向选择：
|
||
1. 在用户端【待支付】页面进行支付
|
||
2. 在快递员端【扫码支付】页面进行支付，可选择微信或支付宝进行支付，分别生成不同的收款码，用户进行扫码支付；
|
||
3. 点击页面左上方返回按钮页面返回至上一页；
|
||
4. 两种方式支付成功，均显示支付成功页面，点击【知道了】，返回任务列表首页
|
||
2. 到付→点击【取件】按钮，进入取件成功页面，点击返回主页按钮进入任务列表主页
|
||
## 2.4、分析
|
||
支付业务与其他业务相比，相对独立，所以比较适合将支付业务划分为一个微服务，而支付业务并不关系物流业务中运输、取派件等业务，只关心付款金额、付款平台、所支付的订单等。
|
||
支付微服务在整个系统架构中的业务时序图：
|
||
## 2.5、开发环境
|
||
### 2.5.1、微服务工程规范
|
||
在神领物流项目中，微服务代码是独立的工程（**非聚合项目结构**），这样更适合多团队间的协作，在部署方面更加的独立方便。
|
||
1个微服务需要创建3个工程，分别是：
|
||
|
||
- sl-express-ms-xxx-api（定义Feign接口）
|
||
- sl-express-ms-xxx-domain（定义DTO、枚举对象）
|
||
- sl-express-ms-xxx-service（微服务的实现）
|
||
|
||
它们之间的依赖关系如下：
|
||
|
||
### 2.5.2、拉取代码
|
||
需要拉取的工程有3个：
|
||
|
||
| 工程名 | git地址 |
|
||
| --- | --- |
|
||
| sl-express-ms-trade-domain | [http://git.sl-express.com/sl/sl-express-ms-trade-domain.git](http://git.sl-express.com/sl/sl-express-ms-trade-domain.git) |
|
||
| sl-express-ms-trade-api | [http://git.sl-express.com/sl/sl-express-ms-trade-api.git](http://git.sl-express.com/sl/sl-express-ms-trade-api.git) |
|
||
| sl-express-ms-trade-service | [http://git.sl-express.com/sl/sl-express-ms-trade-service.git](http://git.sl-express.com/sl/sl-express-ms-trade-service.git) |
|
||
|
||
在idea中拉取开发会有2种方式：
|
||
|
||
- 每一个工程打开一个idea窗口
|
||
- 将多个工程合并到一个idea窗口开发（非maven聚合），每一个工程作为一个module进行开发
|
||
|
||
在这里我们建议使用第2中方法，这样在开发过程中可以减少多窗口间的切换。
|
||
拉取代码完成后，需要添加到项目的modules中：
|
||
|
||
|
||
git分支说明：
|
||
|
||
在学习阶段我们统一使用**master**分支。
|
||
下面展现了支付微服务的工程结构：
|
||
```erlang
|
||
├─sl-express-ms-trade-api 支付Feign接口
|
||
├─sl-express-ms-trade-domain 接口DTO实体
|
||
└─sl-express-ms-trade-service 支付具体实现
|
||
├─com.sl.ms.trade.config 配置包，二维码、Redisson、xxl-job
|
||
├─com.sl.ms.trade.constant 常量类包
|
||
├─com.sl.ms.trade.controller web控制器包
|
||
├─com.sl.ms.trade.entity 数据库实体包
|
||
├─com.sl.ms.trade.enums 枚举包
|
||
├─com.sl.ms.trade.handler 三方平台的对接实现（支付宝、微信）
|
||
├─com.sl.ms.trade.job 定时任务，扫描支付状态
|
||
├─com.sl.ms.trade.mapper mybatis接口
|
||
├─com.sl.ms.trade.service 服务包
|
||
├─com.sl.ms.trade.util 工具包
|
||
```
|
||
### 2.5.3、代码规范
|
||
#### 2.5.3.1、DTO对象
|
||
在神领物流项目中，微服务之间的对象传输都使用DTO，命名规范：XxxxDTO（DTO必须大写），并且将DTO类放置到domain工程中，如下：
|
||
|
||
|
||
DTO类中统一使用lombok的@Data注解进行标注。
|
||
|
||
#### 2.5.3.2、数据校验
|
||
微服务之间的接口调用，对于传输的数据是需要做校验的，一般校验方式有2种：
|
||
|
||
- 方式一：采用hibernate-validator注解方式校验，如下：
|
||
|
||
- 方式二：在程序中通过if()进行判断，如下：
|
||
|
||
|
||
我们采用哪一种方式呢？实际上在项目中，我们采用二者结合的方式进行校验。
|
||
对于第一种方式的补充说明：
|
||
|
||
- 在Controller中需要增加`@Validated`注解，来开启校验
|
||
|
||
- 对于表单、url参数校验，在Controller中方法增加校验规则
|
||
|
||
- 对于@RequestBody对象的校验，校验规则写的DTO对象中，统一通过Spring的AOP进行校验，具体在common工程中的`com.sl.transport.common.aspect.ValidatedAspect`进实现：
|
||
|
||
|
||
#### 2.5.3.3、自定义异常
|
||
在神领物流项目中，我们统一做了自定义异常的处理。
|
||
定义了2个异常：
|
||
|
||
- `com.sl.transport.common.exception.SLException`
|
||
- 用于微服务之前接口调用抛出的异常
|
||
- `com.sl.transport.common.exception.SLWebException`
|
||
- 用于前后端交互时抛出的异常
|
||
|
||
SLException的定义：
|
||
|
||
SLWebException的定义：
|
||
|
||
这两个异常的区别在于code、status的值不同。
|
||
:::danger
|
||
**疑问：为什么不使用一个，而是要设置两个？**
|
||
这个主要是前端和后端的设计不同，一般在微服务间接口调用时会采用标准的RESTful方式，按照RESTful的规范响应的状态码要使用标准的http状态码，成功->200，失败->500，没有权限->401等。
|
||
而前后端进行交互时，一般都是响应200，即使出错也是200，只是**响应结果中**通过msg和code进行表达是否成功。
|
||
基于以上的场景，所以设置了两个异常类。
|
||
:::
|
||
统一异常处理：
|
||
具体的业务逻辑在`com.sl.transport.common.handler.GlobalExceptionHandler`中实现。
|
||
关键代码如下：
|
||
|
||
在该类中对于4种异常做处理，分别是：
|
||
|
||
- `ValidationException`
|
||
|
||
- `SLException`
|
||
|
||
- `SLWebException`
|
||
|
||
- `Exception`
|
||
|
||
#### 2.5.3.4、@Resource注入
|
||
在项目中，涉及到注入Spring容器中bean对象时，均使用`@Resource`，目前IDEA不推荐使用`@Autowired`，原因是它是Spring提供，并非是Java标准，而`@Resource`是Java标准中定义的，建议使用。
|
||
如果想要使用`@Autowired`的话，建议通过构造器注入。
|
||
|
||
|
||
|
||
两者区别：
|
||
|
||
- @Autowired：默认是ByType，可以使用@Qualifier指定Name，可以对构造器、方法、参数、字段使用。
|
||
- @Resource：默认ByName，如果找不到则ByType，只能对方法、字段使用，不能用于构造器。
|
||
- @Autowired是Spring提供的，@Resource是JSR-250提供的。
|
||
- 总结：基本上@Resource可以完全替代@Autowired。
|
||
### 2.5.4、配置文件
|
||
#### 2.5.4.1、SpringBoot配置文件
|
||
|
||
|
||
| 文件 | 说明 |
|
||
| --- | --- |
|
||
| bootstrap.yml | 通用配置项，服务名、日志文件、swagger配置等 |
|
||
| bootstrap-local.yml | 多环境配置，本地开发环境 |
|
||
| bootstrap-prod.yml | 多环境配置，生成环境（学习阶段忽略该文件） |
|
||
| bootstrap-stu.yml | 多环境配置，学生101环境 |
|
||
| bootstrap-test.yml | 多环境配置，开发组测试环境（学习阶段忽略该文件） |
|
||
|
||
对于配置文件的补充说明：
|
||
|
||
- 关于swagger的配置，统一在【`com.sl.transport.common.properties.SwaggerConfigProperties`】中读取，并且在【`com.sl.transport.common.config.Knife4jConfiguration`】中进行了初始化Knife4j。
|
||
- `spring.profiles.active`默认`local`，部署发布到101机器，在Jenkins中发布时设置为stu。
|
||
```shell
|
||
#启动dokcer命令
|
||
docker run -d -p $SERVER_PORT:8080 --name $SERVER_NAME -e SERVER_PORT=8080 -e SPRING_CLOUD_NACOS_DISCOVERY_IP=${SPRING_CLOUD_NACOS_DISCOVERY_IP} -e SPRING_CLOUD_NACOS_DISCOVERY_PORT=${port} -e SPRING_PROFILES_ACTIVE=stu $SERVER_NAME:$SERVER_VERSION
|
||
```
|
||
|
||
:::danger
|
||
通过环境变量的方式配置了spring.profiles.active、发布到注册中心的ip和端口。
|
||
规则：环境变量统一采用大写字母，不允许使用.-符号，采用下划线“_”取代点“.” 减号“-”直接删除。
|
||
:::
|
||
|
||
- 为了与101环境中服务互通，所以在local环境中固定设置了注册到注册中心的服务地址
|
||
|
||
- 具体的一些项目配置统一使用nacos的配置中心管理，并且在这里使用nacos的共享配置机制，这样可以在多个项目中共享相同的配置
|
||
|
||
#### 2.5.4.2、seata配置
|
||
```yaml
|
||
seata:
|
||
registry:
|
||
type: nacos
|
||
nacos:
|
||
server-addr: 192.168.150.101:8848

tx-service-group: sl-seata # 事务组名称
|
||
service:
|
||
vgroup-mapping: # 事务组与cluster的映射关系
|
||
sl-seata: default
|
||
```
|
||
seata服务的配置：
|
||
```properties
|
||
#指定seata存储的数据库
|
||
store.mode = db
|
||
store.db.datasource = druid
|
||
store.db.dbType = mysql
|
||
store.db.driverClassName = com.mysql.cj.jdbc.Driver
|
||
store.db.url = jdbc:mysql://192.168.150.101:3306/seata?useUnicode=true&characterEncoding=utf8&autoReconnect=true&allowMultiQueries=true&useSSL=false
|
||
store.db.user = root
|
||
store.db.password = 123
|
||
store.db.minConn = 5
|
||
store.db.maxConn = 100
|
||
store.db.globalTable = global_table
|
||
store.db.branchTable = branch_table
|
||
store.db.lockTable = lock_table
|
||
store.db.distributedLockTable = distributed_lock
|
||
store.db.queryLimit = 100
|
||
store.db.maxWait = 5000
|
||
```
|
||
seata服务地址： [http://seata.sl-express.com/](http://seata.sl-express.com/) 账号信息：seata/seata
|
||
#### 2.5.4.3、mysql配置
|
||
```yaml
|
||
spring:
|
||
datasource: #数据库的配置
|
||
driver-class-name: ${jdbc.driver:com.mysql.cj.jdbc.Driver}
|
||
url: ${jdbc.url}
|
||
username: ${jdbc.username}
|
||
password: ${jdbc.password}
|
||
```
|
||
具体的配置项在每个微服务自己的配置文件中，例如支付服务：
|
||
```properties
|
||
jdbc.url = jdbc:mysql://192.168.150.101:3306/sl_trade?useUnicode=true&characterEncoding=utf8&autoReconnect=true&allowMultiQueries=true&useSSL=false
|
||
jdbc.username = root
|
||
jdbc.password = 123
|
||
```
|
||
:::danger
|
||
需要说明的是，${jdbc.driver:com.mysql.cj.jdbc.Driver} 这种写法冒号后面的是默认值，如果不配置jdbc.driver就采用默认值。
|
||
:::
|
||
#### 2.5.4.4、mybatis-plus配置
|
||
```yaml
|
||
mybatis-plus:
|
||
configuration:
|
||
#在映射实体或者属性时，将数据库中表名和字段名中的下划线去掉，按照驼峰命名法映射
|
||
map-underscore-to-camel-case: true
|
||
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
|
||
#log-impl: org.apache.ibatis.logging.slf4j.Slf4jImpl
|
||
global-config:
|
||
db-config:
|
||
id-type: ASSIGN_ID
|
||
```
|
||
在配置文件中指定的默认的id策略为ASSIGN_ID，只当插入对象ID为空时，自动填充雪花id。
|
||
#### 2.5.4.5、redis配置
|
||
```yaml
|
||
spring:
|
||
redis: #redis的配置
|
||
port: ${redis.port}
|
||
host: ${redis.host}
|
||
password: ${redis.password}
|
||
```
|
||
具体的配置在微服务自身的配置文件中：
|
||
|
||
#### 2.5.4.6、xxl-job配置
|
||
```yaml
|
||
xxl:
|
||
job:
|
||
admin:
|
||
addresses: http://192.168.150.101:28080/xxl-job-admin
|
||

|
||
logpath: /data/applogs/xxl-job/jobhandler
|
||
#执行器日志文件保存天数
|
||
logretentiondays: 30
|
||
```
|
||
### 2.5.5、日志
|
||
项目中统一使用logback日志框架，其配置文件如下：
|
||
```xml
|
||
<?xml version="1.0" encoding="UTF-8"?>
|
||
<!--scan: 当此属性设置为true时，配置文件如果发生改变，将会被重新加载，默认值为true。-->
|
||
<!--scanPeriod: 设置监测配置文件是否有修改的时间间隔，如果没有给出时间单位，默认单位是毫秒。当scan为true时，此属性生效。默认的时间间隔为1分钟。-->
|
||
<!--debug: 当此属性设置为true时，将打印出logback内部日志信息，实时查看logback运行状态。默认值为false。-->
|
||
<configuration debug="false" scan="false" scanPeriod="60 seconds">
|
||
<springProperty scope="context" name="appName" source="spring.application.name"/>
|
||
<!--文件名-->
|
||
<property name="logback.appname" value="${appName}"/>
|
||
<!--文件位置-->
|
||
<property name="logback.logdir" value="/data/logs"/>
|
||
|
||
<!-- 定义控制台输出 -->

# 3、支付渠道管理【阅读代码】
|
||
支付是对接支付平台完成的，例如支付宝、微信、京东支付等，一般在这些平台上需要申请账号信息，通过这些账号信息完成与支付平台的交互，在我们的支付微服务中，将这些数据称之为【支付渠道】，并且将其存储到数据库中，通过程序可以支付渠道进行管理。
|
||
## 3.1、表结构
|
||
支付微服务的数据是：sl_trade，支付渠道的表为：sl_pay_channel，表结构如下：
|
||
|
||
> **其中表中已经包含了2条数据，分别是支付宝和微信的账号信息，可以直接与支付平台对接。**
|
||
|
||
|
||
## 3.2、阅读代码
|
||
阅读代码顺序：Entity → Mapper → Service → Controller
|
||

|
||
|
||
> 注意：由于渠道管理目前项目中没有需求进行维护操作，所以不对外提供Feign接口。
|
||
|
||
### 3.2.1、PayChannelEntity
|
||
:::info
|
||
PayChannelEntity类是对sl_pay_channel表的映射，Entity类继承BaseEntity，在BaseEntity中统一定义了id、created、updated，其中created、updated是使用MybatisPlus自动填充的。

### 3.2.2、PayChannelMapper
|
||
:::info
|
||
PayChannelMapper继承了MP的BaseMapper，并且加了@Mapper注解。
|
||
:::
|
||
```java

```
|
||
### 3.2.3、PayChannelService
|
||
:::info
|
||
该Service中定义了6个方法，可以对支付渠道的数据进行CRUD的管理，其中findByEnterpriseId()方法将是我们常用的一个方法，根据业务商户id查询和通道唯一标记符查询支付渠道。该方法是需要对数据做缓存的，目前并没有实现缓存，这个需要由你来实现。

其他的方法就不进行测试了，同学们可以自行测试。
|
||
# 4、扫码支付【阅读代码】
|
||
扫码支付的基本原理就是通过调用支付平台的接口，提交支付请求，支付平台会返回支付链接，将此支付链接生成二维码，用户通过手机上的支付宝或微信进行扫码支付。流程如下：
|
||
|
||
## 4.1、交易单表结构
|
||
【交易单表 sl_trading】是指，针对于订单进行支付的记录表，其中记录了订单号，支付状态、支付平台、金额、是否有退款等信息。具体表结构如下：
|
||
|
||
## 4.2、代码流程
|
||
下面展现了整体的扫描支付代码调用流程，我们将按照下面的流程进行代码的阅读。
|
||
## 4.3、幂等性处理
|
||
在向支付平台申请支付之前对交易单对象做幂等性处理，主要是防止重复的生成交易单以及一些业务逻辑的处理，具体是在`com.sl.ms.trade.handler.impl.BeforePayHandlerImpl#idempotentCreateTrading()`方法中完成的。
|
||
其代码如下：
|
||
```java
|
||
@Override
|
||
public void idempotentCreateTrading(TradingEntity tradingEntity) throws SLException {
|
||
TradingEntity trading = tradingService.findTradByProductOrderNo(tradingEntity.getProductOrderNo());
|
||
if (ObjectUtil.isEmpty(trading)) {
|
||
//新交易单，生成交易号
|
||
Long id = Convert.toLong(identifierGenerator.nextId(tradingEntity));
|
||
tradingEntity.setId(id);
|
||
tradingEntity.setTradingOrderNo(id);
|
||
return;
|
||
}
|
||
|
||
TradingStateEnum tradingState = trading.getTradingState();
|
||
if (ObjectUtil.equalsAny(tradingState, TradingStateEnum.YJS, TradingStateEnum.MD)) {
|
||
//已结算、免单：直接抛出重复支付异常
|
||
throw new SLException(TradingEnum.TRADING_STATE_SUCCEED);
|
||
} else if (ObjectUtil.equals(TradingStateEnum.FKZ, tradingState)) {
|
||
//付款中，如果支付渠道一致，说明是重复，抛出支付中异常，否则需要更换支付渠道
|
||
//举例：第一次通过支付宝付款，付款中用户取消，改换了微信支付
|
||
if (StrUtil.equals(trading.getTradingChannel(), tradingEntity.getTradingChannel())) {
|
||
throw new SLException(TradingEnum.TRADING_STATE_PAYING);
|
||
} else {
|
||
tradingEntity.setId(trading.getId()); // id设置为原订单的id
|
||
//重新生成交易号，在这里就会出现id 与 TradingOrderNo 数据不同的情况，其他情况下是一样的
|
||
tradingEntity.setTradingOrderNo(Convert.toLong(identifierGenerator.nextId(tradingEntity)));
|
||
}
|
||
} else if (ObjectUtil.equalsAny(tradingState, TradingStateEnum.QXDD, TradingStateEnum.GZ)) {
|
||
//取消订单,挂账：创建交易号，对原交易单发起支付
|
||
tradingEntity.setId(trading.getId()); // id设置为原订单的id
|
||
//重新生成交易号，在这里就会出现id 与 TradingOrderNo 数据不同的情况，其他情况下是一样的
|
||
tradingEntity.setTradingOrderNo(Convert.toLong(identifierGenerator.nextId(tradingEntity)));
|
||
} else {
|
||
//其他情况：直接交易失败
|
||
throw new SLException(TradingEnum.PAYING_TRADING_FAIL);
|
||
}
|
||
}
|
||
```
|
||
在此代码中，主要是逻辑是：
|
||
|
||
- 如果根据订单号查询交易单数据，如果不存在说明新交易单，生成交易单号后直接返回，这里的交易单号也是使用雪花id。
|
||
- 如果支付状态是已经【支付成功】或是【免单 - 不需要支付】，直接抛出异常。
|
||
- 如果支付状态是【付款中】，此时有两种情况
|
||
- 如果支付渠道相同（此前使用支付宝付款，本次也是使用支付宝付款），这种情况抛出异常
|
||
- 如果支付渠道不同，我们是允许在生成二维码后更换支付渠道，此时需要重新生成交易单号，此时交易单号与id将不同。
|
||
- 如果支付状态是【取消订单】或【挂账】，将id设置为原交易号，交易号重新生成，这样做的目的是既保留了原订单的交易号，又可以生成新的交易号（不重新生成的话，没有办法在支付平台进行支付申请），与之前不会有影响。
|
||
## 4.4、HandlerFactory
|
||
对于NativePayHandler会有不同平台的实现，比如：支付宝、微信，每个平台的接口参数、返回值都不一样，所以是没有办法共用的，只要是每个平台都去编写一个实现类。
|
||
那问题来了，我们该如何选择呢？
|
||
在这里我们采用了**工厂模式**进行获取对应的NativePayHandler实例，在不同的渠道实现类中，都指定了`@PayChannel`注解，通过`type`属性指定具体的平台（支付宝/微信）：
|
||
|
||
|
||
有了这个注解标识后，在HandlerFactory中就可以根据指定的参数获取对应的渠道实现。
|
||
核心代码如下：
|
||
```java
|
||
public static <T> T get(PayChannelEnum payChannel, Class<T> handler) {
|
||
Map<String, T> beans = SpringUtil.getBeansOfType(handler);
|
||
for (Map.Entry<String, T> entry : beans.entrySet()) {
|
||
PayChannel payChannelAnnotation = entry.getValue().getClass().getAnnotation(PayChannel.class);
|
||
if (ObjectUtil.isNotEmpty(payChannelAnnotation) && ObjectUtil.equal(payChannel, payChannelAnnotation.type())) {
|
||
return entry.getValue();
|
||
}
|
||
}
|
||
return null;
|
||
}
|
||
```
|
||
使用：
|
||
|
||
## 4.4、生成二维码
|
||
支付宝或微信的扫码支付返回是一个链接，并不是二维码，所以我们需要根据链接生成二维码，生成二维码的库使用的是：（最终生成的二维码图片使用的base64字符串返回给前端）
|
||
具体代码实现：
|
||
```java

@Service

public class QRCodeServiceImpl implements QRCodeService {

@Resource
|
||
private QRCodeConfig qrCodeConfig;
|
||
|
||
@Override
|
||
public String generate(String content, PayChannelEnum payChannel) {
|
||
QrConfig qrConfig = new QrConfig();
|
||
//设置边距
|
||
qrConfig.setMargin(this.qrCodeConfig.getMargin());
|
||
//二维码颜色
|
||
qrConfig.setForeColor(HexUtil.decodeColor(this.qrCodeConfig.getForeColor()));
|
||
//设置背景色
|
||
qrConfig.setBackColor(HexUtil.decodeColor(this.qrCodeConfig.getBackColor()));
|
||
//纠错级别
|
||
qrConfig.setErrorCorrection(ErrorCorrectionLevel.valueOf(this.qrCodeConfig.getErrorCorrectionLevel()));
|
||
//设置宽
|
||
qrConfig.setWidth(this.qrCodeConfig.getWidth());
|
||
//设置高
|
||
qrConfig.setHeight(this.qrCodeConfig.getHeight());
|
||
if (ObjectUtil.isNotEmpty(payChannel)) {
|
||
//设置logo
|
||
qrConfig.setImg(this.qrCodeConfig.getLogo(payChannel));
|
||
}
|
||
return QrCodeUtil.generateAsBase64(content, qrConfig, ImgUtil.IMAGE_TYPE_PNG);
|
||
}
|
||
|
||
@Override
|
||
public String generate(String content) {
|
||
return generate(content, null);
|
||
}
|
||
|
||
}
|
||
|
||
```
|
||
具体的配置存储在nacos中：
|
||
```properties
|
||
#二维码配置
|
||
#边距，二维码和背景之间的边距
|
||
qrcode.margin = 2
|
||
#二维码颜色，默认黑色
|
||
qrcode.fore-color = #000000
|
||
#背景色，默认白色
|
||
qrcode.back-color = #ffffff
|
||
#低级别的像素块更大，可以远距离识别，但是遮挡就会造成无法识别。高级别则相反，像素块小，允许遮挡一定范围，但是像素块更密集。
|
||
#纠错级别，可选参数：L、M、Q、H，默认：M
|
||
qrcode.error-correction-level = M
|
||
#宽
|
||
qrcode.width = 300
|
||
#高
|
||
qrcode.height = 300

## 4.6、优化（练习）
|
||
在生成二维码时，我们采用的是服务端生成二维码方式，这种方式会比较消耗服务器的CPU、内存资源，比较好的做法是生成二维码的动作交由客户端（前端）来生成。
|
||
实际上，我们前端已经做了兼容处理，在返回的【qrCode】字段中，如果内容以【data:image/png;】开头，直接展现，否则就将返回的数据（支付宝或微信返回的原始数据，例如：https://qr.alipay.com/bax034140c7lyawo6oiy55f2）生成二维码。
|
||
这个优化交由学生来完成。
|
||
## 4.7、支付宝扫码支付
|
||
### 4.7.1、AlipayConfig
|
||
在项目中，通`com.sl.ms.trade.handler.alipay.AlipayConfig#getConfig(Long enterpriseId)`方法可以按照商户id查询支付宝的配置，如果配置查询不到会抛出异常。
|
||
代码如下：
|
||
```java
|
||
package com.sl.ms.trade.handler.alipay;
|
||
|
||
import cn.hutool.core.convert.Convert;
|
||
import cn.hutool.core.util.ObjectUtil;
|
||
import cn.hutool.core.util.StrUtil;
|
||
import cn.hutool.extra.spring.SpringUtil;
|
||
import com.alipay.easysdk.kernel.Config;
|
||
import com.sl.ms.trade.constant.TradingConstant;
|
||
import com.sl.ms.trade.entity.PayChannelEntity;
|
||
import com.sl.ms.trade.enums.TradingEnum;
|
||
import com.sl.ms.trade.service.PayChannelService;
|
||
import com.sl.transport.common.exception.SLException;
|
||
|
||
/**
|
||
* 支付宝支付的配置
|
||
*/
|
||
public class AlipayConfig {
|
||
|
||
/**
|
||
* 将支付渠道配置转化为支付宝的配置
|
||
*
|
||
* @param enterpriseId 商户ID
|
||
* @return 支付宝的配置
|
||
*/
|
||
public static Config getConfig(Long enterpriseId) {
|
||
// 查询配置
|
||
PayChannelService payChannelService = SpringUtil.getBean(PayChannelService.class);
|
||
PayChannelEntity payChannel = payChannelService.findByEnterpriseId(enterpriseId, TradingConstant.TRADING_CHANNEL_ALI_PAY);
|
||
|
||
if (ObjectUtil.isEmpty(payChannel)) {
|
||
throw new SLException(TradingEnum.CONFIG_EMPTY);
|
||
}
|
||
|
||
Config config = new Config();
|
||
config.protocol = "https";
|
||
config.gatewayHost = payChannel.getDomain();
|
||
config.signType = "RSA2";
|
||
config.appId = payChannel.getAppId();
|
||
//配置应用私钥
|
||
config.merchantPrivateKey = payChannel.getMerchantPrivateKey();
|
||
//配置支付宝公钥
|
||
config.alipayPublicKey = payChannel.getPublicKey();
|
||
//可设置异步通知接收服务地址（可选）
|
||
config.notifyUrl = StrUtil.replace(payChannel.getNotifyUrl(), "{enterpriseId}", Convert.toStr(enterpriseId));
|
||
//设置AES密钥，调用AES加解密相关接口时需要（可选）
|
||
config.encryptKey = payChannel.getEncryptKey();
|
||
return config;
|
||
}
|
||
|
||
}
|
||
|
||
```
|
||
关于异步通知的url的说明：
|
||
数据库表中存储的数据类似这样：`[https://61d25503.cpolar.cn/trade/notify/alipay/{enterpriseId}](https://61d25503.cpolar.cn/trade/notify/alipay/{enterpriseId})`
|
||
其中，`61d25503.cpolar.cn`这个域名是内网穿透的地址，后面会将，暂时忽略。`{enterpriseId}`这个是占位符，在真正设置值时，会用【商户id】进行替换，最终的通知地址类似：`[https://61d25503.cpolar.cn/trade/notify/alipay/2088241317544335](https://61d25503.cpolar.cn/trade/notify/alipay/2088241317544335)`

- 通过`createHttpClient()`方法封装了请求微信接口必要的参数，最后返回`CloseableHttpClient`对象。
|
||
- 封装了`doGet()、doPost()`方便对微信接口进行调用。

# 5、基础服务【阅读代码】
|
||
在支付宝或微信平台中，支付方式是多种多样的，对于一些服务而言是通用的，比如：查询交易单、退款、查询退款等，所以我们将基于这些通用的接口封装基础服务。
|
||
## 5.1、查询交易
|
||
用户创建交易后，到底有没有支付成功，还是取消支付，这个可以通过查询交易单接口查询的，支付宝和微信也都提供了这样的接口服务。
|
||
### 5.1.1、Controller
|
||
```java
|
||
/***
|
||
* 统一收单线下交易查询
|
||
* 该接口提供所有支付订单的查询，商户可以通过该接口主动查询订单状态，完成下一步的业务逻辑。
|
||
*
|
||
* @param tradingOrderNo 交易单号
|
||
* @return 交易单
|
||
*/
|
||
@PostMapping("query/{tradingOrderNo}")
|
||
@ApiOperation(value = "查询统一收单线下交易", notes = "查询统一收单线下交易")
|
||
@ApiImplicitParam(name = "tradingOrderNo", value = "交易单", required = true)
|
||
public TradingDTO queryTrading(@PathVariable("tradingOrderNo") Long tradingOrderNo) {
|
||
return this.basicPayService.queryTrading(tradingOrderNo);
|
||
}
|
||
```
|
||
### 5.1.2、Service
|
||
在Service中实现了交易单查询的逻辑，代码结构与扫描支付类似。具体与支付平台的对接由BasicPayHandler完成。
|
||
```java
|
||
@Override
|
||
public TradingDTO queryTrading(Long tradingOrderNo) throws SLException {
|
||
//通过单号查询交易单数据
|
||
TradingEntity trading = this.tradingService.findTradByTradingOrderNo(tradingOrderNo);
|
||
//查询前置处理：检测交易单参数
|
||
this.beforePayHandler.checkQueryTrading(trading);
|
||
|
||
String key = TradingCacheConstant.QUERY_PAY + tradingOrderNo;
|
||
RLock lock = redissonClient.getFairLock(key);
|
||
try {
|
||
//获取锁
|
||
if (lock.tryLock(TradingCacheConstant.REDIS_WAIT_TIME, TimeUnit.SECONDS)) {
|
||
//选取不同的支付渠道实现
|
||
BasicPayHandler handler = HandlerFactory.get(trading.getTradingChannel(), BasicPayHandler.class);
|
||
Boolean result = handler.queryTrading(trading);
|
||
if (result) {
|
||
//如果交易单已经完成，需要将二维码数据删除，节省数据库空间，如果有需要可以再次生成
|
||
if (ObjectUtil.equalsAny(trading.getTradingState(), TradingStateEnum.YJS, TradingStateEnum.QXDD)) {
|
||
trading.setQrCode("");
|
||
}
|
||
//更新数据
|
||
this.tradingService.saveOrUpdate(trading);
|
||
}
|
||
return BeanUtil.toBean(trading, TradingDTO.class);
|
||
}
|
||
throw new SLException(TradingEnum.NATIVE_QUERY_FAIL);
|
||
} catch (SLException e) {
|
||
throw e;
|
||
} catch (Exception e) {
|
||
log.error("查询交易单数据异常: trading = {}", trading, e);
|
||
throw new SLException(TradingEnum.NATIVE_QUERY_FAIL);
|
||
} finally {
|
||
lock.unlock();
|
||
}
|
||
}
|
||
```
|
||
### 5.1.3、支付宝实现
|
||
```java
|
||
@Override
|
||
public Boolean queryTrading(TradingEntity trading) throws SLException {
|
||
//查询配置
|
||
Config config = AlipayConfig.getConfig(trading.getEnterpriseId());
|
||
//Factory使用配置
|
||
Factory.setOptions(config);
|
||
AlipayTradeQueryResponse queryResponse;
|
||
try {
|
||
//调用支付宝API：通用查询支付情况
|
||
queryResponse = Factory
|
||
.Payment
|
||
.Common()
|
||
.query(String.valueOf(trading.getTradingOrderNo()));
|
||
} catch (Exception e) {
|
||
String msg = StrUtil.format("查询支付宝统一下单失败：trading = {}", trading);
|
||
log.error(msg, e);
|
||
throw new SLException(msg, TradingEnum.NATIVE_QUERY_FAIL.getCode(), TradingEnum.NATIVE_QUERY_FAIL.getStatus());
|
||
}
|
||
|
||
//修改交易单状态
|
||
trading.setResultCode(queryResponse.getSubCode());
|
||
trading.setResultMsg(queryResponse.getSubMsg());
|
||
trading.setResultJson(JSONUtil.toJsonStr(queryResponse));
|
||
|
||
boolean success = ResponseChecker.success(queryResponse);
|
||
//响应成功，分析交易状态
|
||
if (success) {
|
||
String tradeStatus = queryResponse.getTradeStatus();
|
||
if (StrUtil.equals(TradingConstant.ALI_TRADE_CLOSED, tradeStatus)) {
|
||
//支付取消：TRADE_CLOSED（未付款交易超时关闭，或支付完成后全额退款）
|
||
trading.setTradingState(TradingStateEnum.QXDD);
|
||
} else if (StrUtil.equalsAny(tradeStatus, TradingConstant.ALI_TRADE_SUCCESS, TradingConstant.ALI_TRADE_FINISHED)) {
|
||
// TRADE_SUCCESS（交易支付成功）
|
||
// TRADE_FINISHED（交易结束，不可退款）
|
||
trading.setTradingState(TradingStateEnum.YJS);
|
||
} else {
|
||
//非最终状态不处理，当前交易状态：WAIT_BUYER_PAY（交易创建，等待买家付款）不处理
|
||
return false;
|
||
}
|
||
return true;
|
||
}
|
||
throw new SLException(trading.getResultJson(), TradingEnum.NATIVE_QUERY_FAIL.getCode(), TradingEnum.NATIVE_QUERY_FAIL.getStatus());
|
||
}
|
||
```
|
||
### 5.1.4、微信支付实现
|
||
```java
|
||
@Override
|
||

|
||
// 获取微信支付的client对象

//请求参数
|
||
Map<String, Object> params = MapUtil.<String, Object>builder()
|
||

|
||
.build();

WeChatResponse response;
|
||
try {

|
||
String tradeStatus = jsonObject.getStr("trade_state");
|
||
if (StrUtil.equalsAny(tradeStatus, TradingConstant.WECHAT_TRADE_CLOSED, TradingConstant.WECHAT_TRADE_REVOKED)) {
|
||
trading.setTradingState(TradingStateEnum.QXDD);
|
||
} else if (StrUtil.equalsAny(tradeStatus, TradingConstant.WECHAT_REFUND_SUCCESS, TradingConstant.WECHAT_TRADE_REFUND)) {
|
||
trading.setTradingState(TradingStateEnum.YJS);
|
||
} else if (StrUtil.equalsAny(tradeStatus, TradingConstant.WECHAT_TRADE_NOTPAY)) {

# 6、同步支付状态【阅读代码】
|
||
在支付平台创建交易单后，如果用户支付成功，我们怎么知道支付成功了呢？一般的做法有两种，分别是【异步通知】和【主动查询】，基本的流程如下：
|
||
说明：
|
||
|
||
- 在用户支付成功后，【步骤4】支付平台会通知【支付微服务】，这个就是异步通知，需要在【支付微服务】中对外暴露接口
|
||
- 由于网络的不确定性，异步通知可能出现故障【步骤6】
|
||
- 支付微服务中需要有定时任务，查询正在支付中的订单的状态
|
||
- 可以看出【异步通知】与【主动定时查询】这两种方式是互不的，缺一不可。
|
||
## 6.1、异步通知
|
||
支付宝和微信都提供了异步通知功能，具体参考官方文档：
|
||
### 6.1.1、内网穿透
|
||
异步通知的是需要通过外网的域名地址请求到的，由于我们还没有真正上线，那支付平台如何请求到我们本地服务的呢？
|
||
这里可以使用【内网穿透】技术来实现，通过【内网穿透软件】将内网与外网通过隧道打通，外网可以读取内网中的数据。
|
||
在这里推荐2个免费的内网穿透服务，分别是：
|
||
这里以【cpolar】为例，介绍使用方法：
|
||
**第一步，安装cpolar：**
|
||
Windows的安装包在资料目录中，101机器的已经按照完成，在 `/usr/local/src/cpolar`目录下。
|
||
**第二步，注册账号并且登录。**
|
||
**第三步，设置token：**
|
||
请求 [https://dashboard.cpolar.com/get-started](https://dashboard.cpolar.com/get-started) 页面，查看命令`./cpolar authtoken xxxx`后面的【xxxx】就是你自己的token，每个人是不一样的。token只需要设置一次。
|
||
**第四步，设置端口映射：**
|
||
例如：`./cpolar http 18096`端口改成你自己的端口。
|
||
在线查看：
|
||
|
||
将`https`协议的url写入到`sl_pay_channel`表的`notify_url`字段中，例如：`[https://39808c89.vip.cpolar.cn/trade/notify/wx/{enterpriseId}](https://39808c89.vip.cpolar.cn/trade/notify/wx/{enterpriseId})`。
|
||
:::danger
|
||
注意：cpolar的域名每次启动服务都不一样，每个人的也都不一样，需要改成你自己的那个域名。

:::danger

异步通知debug测试时，三方支付平台会发起多个重试请求，会导致debug无法拦截每个请求，需要将debug模式设置成单线程模式，如下：（断点红球上点右键进行设置）

### 6.1.5、网关对外暴露接口
|
||
bootsarp-{profile}.yml文件中增加如下内容：
|
||
```yaml
|
||
- id: sl-express-ms-trade
|
||
uri: lb://sl-express-ms-trade
|
||
predicates:
|
||
- Path=/trade/notify/**
|
||
filters:
|
||
- StripPrefix=1
|
||
- AddRequestHeader=X-Request-From, sl-express-gateway
|
||
```
|
||
:::danger
|
||
说明：对于支付系统在网关中的暴露仅仅暴露通知接口，其他接口不暴露。
|
||

|
||
## 6.2、定时任务
|
||
一般在项目中实现定时任务主要是两种技术方案，一种是Spring Task，另一种是xxl-job，其中Spring Task是适合单体项目中使用，而xxl-job是分布式任务调度框架，更适合在分布式项目中使用，所以在支付微服务中我们将采用xxl-job来实现。
|
||
### 6.2.1、分布式任务调度
|
||
在微服务架构体系中，服务之间通过网络交互来完成业务处理的，在分布式架构下，一个服务往往会部署多个实例来运行我们的业务，如果在这种分布式系统环境下运行任务调度，我们称之为**分布式任务调度**。
|
||
|
||
分布式系统的特点，并且提高任务的调度处理能力：
|
||
|
||
- 并行任务调度
|
||
- 集群部署单个服务，这样就可以多台计算机共同去完成任务调度，我们可以将任务分割为若干个分片，由不同的实例并行执行，来提高任务调度的处理效率。
|
||
- 高可用
|
||
- 若某一个实例宕机，不影响其他实例来执行任务。
|
||
- 弹性扩容
|
||
- 当集群中增加实例就可以提高并执行任务的处理效率。
|
||
- 任务管理与监测
|
||
- 对系统中存在的所有定时任务进行统一的管理及监测。
|
||
- 让开发人员及运维人员能够时刻了解任务执行情况，从而做出快速的应急处理响应。
|
||
### 6.2.2、xxl-Job简介
|
||
XXL-JOB是一个分布式任务调度平台，其核心设计目标是开发迅速、学习简单、轻量级、易扩展。现已开放源代码并接入多家公司线上产品线，开箱即用。
|
||
官网地址：
|
||

|
||
|
||
### 7.2.3、部署安装
|
||
我们采用docker进行部署安装xxl-job的调度中心，目前已经安装完成，直接访问即可：[http://xxl-job.sl-express.com/xxl-job-admin/](http://xxl-job.sl-express.com/xxl-job-admin/)
|
||
|
||
安装命令：
|
||
```shell
|
||
docker run \
|
||
-e PARAMS="--spring.datasource.url=jdbc:mysql://192.168.150.101:3306/xxl_job?Unicode=true&characterEncoding=UTF-8 \
|
||
--spring.datasource.username=root \
|
||
--spring.datasource.password=123" \
|
||
--restart=always \
|
||
-p 28080:8080 \
|
||
-v xxl-job-admin-applogs:/data/applogs \
|
||
--name xxl-job-admin \
|
||
-d \
|
||
xuxueli/xxl-job-admin:2.3.0
|
||
```
|
||
:::tips
|
||
|
||
- 默认端口映射到28080
|
||
- 日志挂载到/var/lib/docker/volumes/xxl-job-admin-applogs
|
||
- 通过PARAMS环境变量设置数据库链接参数
|
||
- 数据库脚本：[https://gitee.com/xuxueli0323/xxl-job/blob/2.3.0/doc/db/tables_xxl_job.sql](https://gitee.com/xuxueli0323/xxl-job/blob/2.3.0/doc/db/tables_xxl_job.sql)
|
||
:::
|
||
xxl-job共用到8张表，如下：
|
||
|
||
:::tips
|
||
|
||
- xxl_job_lock：任务调度锁表；
|
||
- xxl_job_group：执行器信息表，维护任务执行器信息；
|
||
- xxl_job_info：调度扩展信息表： 用于保存XXL-JOB调度任务的扩展信息，如任务分组、任务名、机器地址、执行器、执行入参和报警邮件等等；
|
||
- xxl_job_log：调度日志表： 用于保存XXL-JOB任务调度的历史信息，如调度结果、执行结果、调度入参、调度机器和执行器等等；
|
||
- xxl_job_log_report：调度日志报表：用户存储XXL-JOB任务调度日志的报表，调度中心报表功能页面会用到；
|
||
- xxl_job_logglue：任务GLUE日志：用于保存GLUE更新历史，用于支持GLUE的版本回溯功能；
|
||
- xxl_job_registry：执行器注册表，维护在线的执行器和调度中心机器地址信息；
|
||
- xxl_job_user：系统用户表；
|
||
:::
|
||
### 6.2.4、编写任务代码
|
||
拉取编写任务的示例代码进行学习：[http://git.sl-express.com/sl/sl-express-xxl-job](http://git.sl-express.com/sl/sl-express-xxl-job)
|
||
|
||
运行之前，首先需要创建执行管理器：
|
||
|
||
创建任务：
|
||
|
||
|
||
:::info
|
||
xxl-job支持的路由策略非常丰富：
|
||
|
||
- FIRST（第一个）：固定选择第一个机器；
|
||
- LAST（最后一个）：固定选择最后一个机器；
|
||
- ROUND（轮询）：在线的机器按照顺序一次执行一个
|
||
- RANDOM（随机）：随机选择在线的机器；
|
||
- CONSISTENT_HASH（一致性HASH）：每个任务按照Hash算法固定选择某一台机器，且所有任务均匀散列在不同机器上。
|
||
- LEAST_FREQUENTLY_USED（最不经常使用）：使用频率最低的机器优先被选举；
|
||
- LEAST_RECENTLY_USED（最近最久未使用）：最久未使用的机器优先被选举；
|
||
- FAILOVER（故障转移）：按照顺序依次进行心跳检测，第一个心跳检测成功的机器选定为目标执行器并发起调度；
|
||
- BUSYOVER（忙碌转移）：按照顺序依次进行空闲检测，第一个空闲检测成功的机器选定为目标执行器并发起调度；
|
||
- SHARDING_BROADCAST(分片广播)：广播触发对应集群中所有机器执行一次任务，同时系统自动传递分片参数；可根据分片参数开发分片任务；

## 6.4、xxl-job任务
|
||
创建xxl-job的任务，首先创建执行器（AppName在nacos中的`sl-express-ms-trade.properties`配置文件中指定）：
|
||
|
||
创建【查询支付状态】任务：
|
||
|
||
创建【查询退款状态】任务：
|
||
|
||
|
||
本地启动服务后会看到注册的ip地址，可能是在101机器无法访问的，如下：
|
||
|
||
如果出现此情况，需要在配置文件中设置参数指定ip地址，如下：
|
||
配置可参考官方文档：[https://www.xuxueli.com/xxl-job/](https://www.xuxueli.com/xxl-job/)
|
||
```yaml
|
||
xxl:
|
||
job:
|
||
executor:
|
||
ip: 192.168.150.1
|
||
```
|
||
重新启动，效果如下：

# 7、面试连环问
|
||
:::info
|
||
面试官问：
|
||
|
||
- 支付二维码的生成你们是在服务端还是在客户端？为什么不在服务端？在客户端生成有什么好处？
|
||
- 用户在选择支付渠道后，可能会反复的切换支付渠道，这块你们是怎么处理的？
|
||
- 用户在申请支付后，发现并没有展示出二维码，这时用户可能会不断的重试，你们有考虑这种情况吗？具体是怎么处理的？
|
||
- 支付渠道可能是多样的，你们的代码是怎么设计的？如果需要停用某个渠道，但是不重启服务，怎么能做到？
|
||
- 支付成功的通知你们是怎处理的？有考虑幂等性吗？如何确保请求是真正来源支付平台的？如果通知没有接收到，你们怎么处理的？
|
||
- xxl-job的分片式广播用过吗？他是如何确保任务节点处理不重复数据的？
