-------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # Spring Cloud微服务项目完整示例 2 | 3 | 目的是为了演示基于Spring Cloud微服务框架，搭建一个接近业务实际场景的项目，只实现了后端项目，前端可以使用VUE或者其他框架。后端框架包括注册中心 Eureka、配置中心Spring Cloud Config、API网关Zuul、客户端负载均衡Ribbon、断路器Hystrix，同时还包括2个后端业务服务，一个用户服务sc-user-service，另一个是数据服务 sc-data-service。 4 | 5 | ## 技术架构图 6 | 7 | 用户从浏览器发起请求，经过浏览器，请求到达Nginx，打开前端页面，由前端页面发起请求后端服务，当请求到达后端Nginx后，Nginx对网关层进行负载，因为网关也需要做HA。此时网关Gateway 接收到请求后，根据请求路径进行动态路由，根据服务发现是User Service 中的服务，则从Ribbon 中选择一台 User Service的实例进行调用，由User Service 返回数据，如果此时User Service 需要使用Data Service的数据，则选择一台Data Service的实例进行调用，然后数据给前端，流程结束。 8 | 9 | ![architecuture](https://raw.githubusercontent.com/rickiechina/Spring-Cloud-Full-Demo/master/images/architecture.png) 10 | 11 | ## 具体实现 12 | 13 | 项目结构如下所示，从module名称，即可理解每个项目的作用了。 14 | 15 | 其中common是一个公共基础包，方便给后台服务引用。 16 | 17 | ![source code](https://raw.githubusercontent.com/rickiechina/Spring-Cloud-Full-Demo/master/images/source-code.png) 18 | 19 | ## 运行微服务应用 20 | 21 | 按顺序启动 eureka、zuul-server、data-service、user-service，另外的hystrix-dashboard和config-server 是可行的module。如下图所示，可以看到每个应用的运行端口号。 22 | 23 | ![application running](https://raw.githubusercontent.com/rickiechina/Spring-Cloud-Full-Demo/master/images/application-run.png) 24 | 25 | 访问 eureka UI，查看服务注册情况。 26 | 27 | 28 | 29 | 每个服务都正常注册到 eureka 注册中心了。 30 | 31 | ![eureka](https://raw.githubusercontent.com/rickiechina/Spring-Cloud-Full-Demo/master/images/eureka.png) 32 | 33 | 通过网关，访问如下URL，获取context user 信息： 34 | 35 | http://localhost:7777/sc-user-service/getContextUserId 36 | 37 | 返回如下结果：{"exceptionType":"[cn.springcloud.book.common.exception.BaseException","code":10001,"businessId":1,"businessMessage":"the user is null, please check","codeEN":"AuthEmptyError"} 38 | 39 | 这是鉴权 filter 返回的异常信息，因为没有在请求头中获取到x-customs-user信息。 40 | 41 | ![auth filter](https://raw.githubusercontent.com/rickiechina/Spring-Cloud-Full-Demo/master/images/auth-filter.png) 42 | 43 | 通过Postman，在请求头中添加 x-customs-user=rickie 信息，然后再次访问URL。 44 | 45 | 46 | 如下图所示，目前返回结果正常。 47 | 48 | ![postman](https://raw.githubusercontent.com/rickiechina/Spring-Cloud-Full-Demo/master/images/postman.png)
