## 🎂整体架构
![整体架构](https://s3.ax1x.com/2020/12/18/rtegcd.png)

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](https://github.com/duyanming/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

```xml

<?xml version="1.0" encoding="utf-8"?>
    <configuration>
      
      <Port>6660</Port>
      <TimeOut>120000</TimeOut>
      <Servers>
        <dc name="Anno.Plugs.TraceService,Anno.Plugs.DLockService,Anno.Plugs.EsLogService" nickname="App001" ip="10.112.93.122" port="6659" timeout="20000" weight="1" />
      </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
    Anno.Plugs.HelloWorldService
    初始化配置
    实现接口：IPlugsConfigurationBootstrap

```cs
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

        }
    
        [AnnoInfo(Desc = "两个整数相减等于几？我来帮你算（x-y=?）")]
        public int Subtraction([AnnoInfo(Desc = "整数X")] int x, [AnnoInfo(Desc = "整数Y")] int y)
        {
