Spring-Cloud-Sleuth

介绍

基于Srping Cloud一系列组件实现高可用的微服务架构。

  • 基于Ribbon实现客户端负载均衡;
  • 基于OpenFeign实现面向服务的接口调用;
  • 基于Eureka实现服务注册中心;
  • 基于Config实现服务的配置中心;
  • 基于Hystrix、Hystrix Dashboard实现服务的熔断、超时、资源隔离的降级及监控;
  • 基于Gateway实现网关路由;
  • 基于Sleuth、Zipkin实现链路监控及可视化;

组件介绍:

  • shen-mall-commons : 基础工具包,提供统一泛型返回结果R、提供基本异常定义

  • shen-mall-goods-service-8083: 商品服务 集成ribbon来实现负载均衡; 集成openfeign来实现面向服务的接口调用; 集成sleuth、zipkin来实现链路的监控; 集成eureka-client来作为注册中心的客户端; 依赖Mybatis进行数据库交互; 依赖lombok、mapstruct工具包简化开发,mapstruct进行Bean的拷贝,Do2Vo、Dto2Do等的转换;

  • shen-mall-order-service-8082:订单服务
    集成ribbon来实现负载均衡; 集成openfeign来实现面向服务的接口调用; 集成sleuth、zipkin来实现链路的监控; 集成eureka-client来作为注册中心的客户端; 依赖Mybatis进行数据库交互; 依赖lombok、mapstruct工具包简化开发,mapstruct进行Bean的拷贝,Do2Vo、Dto2Do等的转换;

  • spring-cloud-gateway-8080:网关服务 集成gateway进行网关路由; 集成Redis进行网关的动态路由、持久化操作; 集成sleuth、zipkin来实现链路的监控; 集成eureka-client来作为注册中心的客户端;

  • spring-cloud-hystrix-dashboard-9092: 提供可视化的熔断界面服务

  • spring-cloud-netflix-eureka-server-9090:注册中心server

  • spring-cloud-user-service-8081
    集成ribbon来实现负载均衡; 集成openfeign来实现面向服务的接口调用; 集成hystrix来实现服务熔断降级、超时降级、资源隔离等; 集成eureka-client来作为注册中心的客户端;

启动方式

订单order、商品goods服务依赖mysql;网关gateway服务动态路由持久化依赖redis;链路监控依赖zipkin服务;服务启用前需要这些基础服务。

  1. 启动 注册中心 eureka 9090服务
  2. 启动 网关路由 gateway 8080服务
  3. 启动 用户user、订单order、商品goods 服务,此处可以启动多端口创建服务集群,进行Ribbon、Openfeign的负载均衡调用
  4. 启动 Hystrix Dashboard 来监控服务降级策略
  5. 启动 Zipkin 进行可视化的链路监控

使用说明

体验点:负载均衡、面向服务的Restful接口调用、熔断_超时_资源隔离降级、网关路由等

  • 测试网关路由入口:spring-cloud-gateway-8080 a. 测试下单流程链路监控,入口为 http://localhost:8080/shen-mall/order,会通过网关路由至订单服务的 /order 接口; b. 测试自定义断言Predicate、过滤器Filter、负载均衡、动态路由及持久化,需要启用 application_bak.yml 配置;

  • 测试链路监控入口:shen-mall-order-service-8082服务的Post /order接口

  • 测试熔断入口:spring-cloud-user-service-8081 用户服务 HystrixController 定义了针对接口级别的熔断降级和超时降级; application.yml 内定义了全局的超时降级、针对openfeign具体接口的资源隔离(线程池/信号量隔离),可以结合Apache Jmeter进行压力测试、结合hystrix-dashboard进行限流监控
