整体架构

整体架构

整体架构主要分为三个部分

  1、注册中心:AnnoCenter

  2、微服务:AnnoService(可以是多个服务例如:订单服务A、库存服务B、支付服务C、用户服务D)

  3、ApiGateway:参考Viper   

📢主要功能

  服务注册中心、服务发现、健康检查、负载均衡、限流、失败重试、链路追踪、资源监控等功能

📦注册中心(AnnoCenter)

  AnnoCenter 是一个服务注册中心,主要职责是 发现服务(例如订单服务A、库存服务B)、存储服务配置信息、健康检查、简单键值KV存储。客户端定时从注册中心获取服务信息缓存到本地。即便注册中心宕机也不影响整个集群运行,因为客户端已经缓存了整个集群的服务信息。但是新加入的服务无法注册进来,需要启动注册中心才可以。   客户端(例如:ApiGateway )发送过来请求时,客户端类库从本地缓存找出能够处理此请求的服务列表(这个过程可能涉及权重等策略)选择一个去处理请求,然后返回,如果失败会有重试机制。   注册中心会定时对每个服务做健康检查,如果连接不上服务则标记此服务为亚健康状态,此时不会将此服务踢出也不会将自服务返回给客户单使用,然后开始重复做检查。如果一分钟内恢复正常则重新标记为健康状态切可以对外提供服务,否则永久踢出服务。

服务注册中心(AnnoCenter) 是整个集群第一个需要运行起来的程序。

配置文件:只需要配置端口、超时时间即可。服务节点信息会在服务注册进来的时候自动写入

      </Servers>
    </configuration>

👑服务(AnnoService)

服务宿主程序,本着约定大于配置的开发原则。 插件式开发具体参考: Packages

命名空间和程序集名称相同,格式为Anno.Plugs.XXXService 例如:Anno.Plugs.HelloWorldService

初始化配置    
实现接口:IPlugsConfigurationBootstrap
using Anno.EngineData;
using System;

namespace Anno.Plugs.HelloWorldService
{
    /// <summary>
    /// 插件启动引导器
    /// DependsOn 依赖的类型程序集自动注入DI容器
    /// </summary>
    [DependsOn(
        //typeof(Domain.Bootstrap)
        //, typeof(QueryServices.Bootstrap)
        //, typeof(Repository.Bootstrap)
        //, typeof(Command.Handler.Bootstrap
        )]
    public class HelloWorldBootStrap : IPlugsConfigurationBootstrap
    {
        /// <summary>
        /// Service 依赖注入构建之后调用
        /// </summary>
        public void ConfigurationBootstrap()
        {
            //throw new NotImplementedException();
        }
        /// <summary>
        /// Service 依赖注入构建之前调用
        /// </summary>
        /// </summary>
        public void PreConfigurationBootstrap()
        {
            //throw new NotImplementedException();
        }
    }
}

功能模块实现 继承: BaseModule

Module命名规范为 XXXModule,以Module结尾 例如:HelloWorldViperModule
