chaokunyang / microservices-event-sourcing Goto Github PK

之前没有用过gradle，想问一下，idea怎么部署启动

代码貌似不够全面，有个老外分享的代码：https://github.com/kbastani/spring-cloud-event-sourcing-example ，对应文章：http://www.kennybastani.com/2016/04/event-sourcing-microservices-spring-cloud.html
各个服务做的均是查询居多，对于事务的控制这块如何实现我研究不透彻，烦请各位git友指点一二。例如：下单时锁库存实现、支付时扣减库存实现等，在event-sourcing模型中如何实现事务控制保证数据一致性？难道是每个服务都要写一个fallback方法自己实现回滚逻辑？涉及到事务的服务都添加event事件？有没有q群交流下，谢谢！

初看了代码，发现每个模块下都有相同的实体类 Account Address...
能有什么方式可以共享实体类，或者更优雅的模式？

能不能出一个maven版本呢能不能出一个maven版本呢能不能出一个maven版本呢

我只发现了个别的表结构，产品表的结构我没有发现

我启动 config-service报错如下：
nested exception is java.lang.NoClassDefFoundError: org/eclipse/jgit/api/errors/RefNotFoundException

我在启动user-service 时报错如下：
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
请问怎么解决

你好，部署起来之后运行发现

加载首页，库存显示无货。

点击商品详情页加载失败

点击商品是后台报错信息

商品点击 获取产品为空

库存服务数据初始化

有些疑问还请不吝赐教：

1.项目启动的服务这么多，怎么监控整个系统的运行状态？
2.是否可以查看每个请求都访问了那些服务？ （或者说一个请求，在服务中的调用顺序有方便的查询方法吗？）

群主能否弄个qq群

有没有qq群，一起讨论

我嘗試在microservices-event-sourcing下的pom.xml加入以下的指令匯入slf4j lib, 但還是出現相同的錯誤訊息

請問要如何處理此issue
