1. 用户点击提交订单按钮后台生成订单编号和订单金额跳转到订单支付页面并发送rabbitMQ消息包含订单编号等信息 1. 用户点击提交订单按钮,后台生成订单编号和订单金额跳转到订单支付页面,并将订单编号等信息发送rabbitMQ消息生产订单
2. 订单消费者接受到订单消息后生成订单记录(未支付) 2. 订单消费者接受到订单消息后,获取订单编号生成订单记录(用户待支付)
3. 用户点击支付按钮时,前端根据订单编号轮询订单信息查询接口,如果订单编号记录已经入库则进行后续支付操作,如果订单编号未入库则返回错误信息(订单异常) 3. 用户点击支付按钮时,前端根据订单编号轮询订单信息查询接口,如果订单编号记录已经入库则进行后续支付操作,如果订单编号未入库则返回错误信息(订单异常)

### 7. 使用google jib插件部署项目到阿里云容器服务
#### 1. 在waynboot-mobile-api子项目pom中添加如下配置
```javascript
<plugin>
<groupId>com.google.cloud.tools</groupId>
<artifactId>jib-maven-plugin</artifactId>
<version>3.0.0</version>
<configuration>
<!--配置基本镜像可以在docker hub网站上寻找合适jdk11版本镜像-->
<from>
<image>adoptopenjdk:11-jre-openj9</image>
</from>
<!--配置最终推送的地址,仓库名,镜像名-->
<to>
<image>registry.cn-shanghai.aliyuncs.com/阿里云容器服务命名空间/你的项目名称
</image>
<tags>
<tag>你的版本号</tag>
<tag>latest</tag>
</tags>
<auth>
<username>你的阿里云镜像服务账号</username>
<password>你的阿里云镜像服务密码</password>
</auth>
</to>
<container>
<mainClass>com.waynboot.modile.ModileAppliction</mainClass>
<jvmFlags>
<jvmFlag>-Xms512m</jvmFlag>
<jvmFlag>-Xmx512m</jvmFlag>
<jvmFlag>-XX:+HeapDumpOnOutOfMemoryError</jvmFlag>
<jvmFlag>-XX:HeapDumpPath=./</jvmFlag>
</jvmFlags>
</container>
</configuration>
<!-- 绑定到maven lifecicle-->
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>build</goal>
</goals>
</execution>
</executions>
</plugin>
```
推送完成后就可以在阿里云容器服务管理控制台中看到自己推送得镜像
![image-20210610163326702](http://cdn.wayn.ltd/img/image-20210610163326702.png)
#### 2. 服务器获通过镜像启动java服务
##### 1.登录阿里云Docker Registry
```javascript
docker login --username=166973****@qq.com registry.cn-shanghai.aliyuncs.com
# 输入命令后会提示输入密码
```
##### 2.从Registry中拉取镜像
```javascript
docker pull registry.cn-shanghai.aliyuncs.com/wayn111/newbee-mall-plus:lastes
```
##### 3.启动java服务
```javascript
docker run -d -p 81:81 --name waynboot-mobile-api registry.cn-shanghai.aliyuncs.com/wayn111/newbee-mall-plus:lastes
# 自此大功能告成
``` ```
