(1). 源码构建

稍微吐槽下,官方提供的Servicecomb Pack案例,是依赖:Docker的.
这样做有优势,可以利用docker快速启动项目(不必理会Pass层的依赖,比如:postgres/mysql…),缺点,不知道真正能快速启动的人有多少,毕竟,不是谁都会Docker的.
“Saga Spring Demo官网详细介绍”

# clone源码后所在目录
lixin-macbook:servicecomb-pack-0.6.0 lixin$ pwd
/Users/lixin/GitRepository/servicecomb-pack-0.6.0

# 编译打包,并构建docker镜像
lixin-macbook:servicecomb-pack-0.6.0 lixin$ mvn clean install -DskipTests -Pdocker -Pdemo

(2). 为sh添加可执行

lixin-macbook:servicecomb-pack-0.6.0 lixin$ cd ./demo/saga-spring-demo/
lixin-macbook:saga-spring-demo lixin$ chmod 755 saga-demo.sh

(3). 启动saga案例

lixin-macbook:saga-spring-demo lixin$ ./saga-demo.sh up
Starting saga-demo:0.6.0
Creating network "saga-spring-demo_default" with the default driver
Creating saga-spring-demo_database_1 ... done
Creating saga-spring-demo_alpha_1    ... done
Creating saga-spring-demo_hotel_1    ... done
Creating saga-spring-demo_car_1      ... done
Creating saga-spring-demo_booking_1  ... done
... ...

(4). 查看docker启动的容器

"Servicecomb Pack Saga Docker"

(5). 测试

业务知识:用户(test),向网站(booking)发起请求,订2辆台(car)和2间房(hotel).

"Saga案例"

# 模拟订车和订房服务.
lixin-macbook:~ lixin$ curl -X POST http://localhost:8083/booking/test/2/2
test booking 2 rooms and 2 cars OK

# 查看服务状态.
lixin-macbook:~ lixin$ curl http://localhost:8081/bookings
[{"id":1,"name":"test","amount":2,"confirmed":true,"cancelled":false}]

(6). 总结

Demo是跑起来了,后续会对源码进行一个深度的剖析.
