微服务架构

Spring Cloud Eureka 基于 Netflix Eureka 做了二次封装 两个组件组成： Eureka Server 注册中心 作为具有服务注册功能的服务器，是服务注册中心，系统中的其他微服务使用 Eureka Client 连接到Eureka Server ，并维持心跳连接以监控各个微服务是否正常运行。 Eureka Client 服务注册 用于简化与服务器的交互，作为轮询负载均衡器，并提供服务的故障切换支持。 启动 Eureka Server 1. 创建Spring项目 2. 填充项目信息 3. 选择项目类型为 Cloud Discovery 中的 Eureka Server 4. 完成创建 5. 添加注解 @EnableEurekaServer @SpringBootApplication @EnableEurekaServer public class EurekaApplication { public static void main(String[] args) { SpringApplication.run(EurekaApplication.class, args); } } 6. 配置 application.yml eureka: client: service-url: defaultZone: http://localhost:8761/eureka/ register-with-eureka: false spring: application: name: eureka server: port: 8761 7. 启动 Eureka Server ...

images 定义 The microservice architectural style is an approach to developing a single application running as a suite of small services, each running its own process and communicating with lightweight mechanisms, often an HTTP resource API. These services are built around business capabilities and independently deployable by fully automated deployment machinery. There is a bare minimum of centralized management of these services, which may be written in different programming languages and use different data storage technologies. ...
