Orleans[NET Core 3.1] 学习笔记(四)( 1 )创建项目
ClassRoom
ClassRoom是一个练手demo,目的是为了能熟悉掌握Orleans的基本知识和使用方法,我会尽量在这个项目中加入更多的知识点,一边学一边练避免我看完文档就忘掉
创建项目
依旧是四个项目起步
项目名称 | 项目类型 | 项目说明 |
---|---|---|
IGrains | .net Core 3.1 类库 | Grain接口库 |
Grains | .net Core 3.1 类库 | 实现Grain的类库 |
Silo_ConsoleApp | .net Core 3.1 控制台 | Silo服务 |
Client_ConsoleApp | .net Core 3.1 控制台 | 客户端程序 |
引用类库
IGrains:
Microsoft.Orleans.Core.Abstractions(3.0.2)
Microsoft.Orleans.CodeGenerator.MSBuild(3.0.2)
Grains:
Microsoft.Orleans.Core.Abstractions(3.0.2)
Microsoft.Orleans.CodeGenerator.MSBuild(3.0.2)
Silo_ConsoleApp:
Microsoft.Orleans.Server(3.0.2)
Client_ConsoleApp:
Microsoft.Orleans.Client(3.0.2)
IGrains 定义
using System.Threading.Tasks;namespace IGrains{ /// <summary> /// 学生 /// </summary> public interface IStudent : Orleans.IGrainWithIntegerKey { /// <summary> /// 打招呼 /// </summary> /// <returns></returns> Task<string> SayHello(); }}
注意Orleans.IGrainWithIntegerKey
,这个决定了Grain的key的类型,是long
还是string
,或者Guid
.
再加个控制台日志帮助类
using System;namespace IGrains{ /// <summary> /// 控制台帮助类 /// </summary> public static class ConsoleHelper { static void WriteColorLine(string str, ConsoleColor color) { ConsoleColor currentForeColor = Console.ForegroundColor; Console.ForegroundColor = color; Console.WriteLine(str); Console.ForegroundColor = currentForeColor; } /// <summary> /// 打印错误信息 /// </summary> /// <param name="str">待打印的字符串</param> /// <param name="color">想要打印的颜色</param> public static void WriteErrorLine(this string str, ConsoleColor color = ConsoleColor.Red) { WriteColorLine(str, color); } /// <summary> /// 打印警告信息 /// </summary> /// <param name="str">待打印的字符串</param> /// <param name="color">想要打印的颜色</param> public static void WriteWarningLine(this string str, ConsoleColor color = ConsoleColor.Yellow) { WriteColorLine(str, color); } /// <summary> /// 打印正常信息 /// </summary> /// <param name="str">待打印的字符串</param> /// <param name="color">想要打印的颜色</param> public static void WriteInfoLine(this string str, ConsoleColor color = ConsoleColor.White) { WriteColorLine(str, color); } /// <summary> /// 打印成功的信息 /// </summary> /// <param name="str">待打印的字符串</param> /// <param name="color">想要打印的颜色</param> public static void WriteSuccessLine(this string str, ConsoleColor color = ConsoleColor.Green) { WriteColorLine(str, color); } }}
Grains 定义
using IGrains;using System;using System.Threading.Tasks;namespace Grains{ /// <summary> /// 学生 /// </summary> public class Student : Orleans.Grain, IStudent { /// <summary> /// 打招呼 /// </summary> /// <returns></returns> public Task<string> SayHello() { var id = this.GrainReference.GrainIdentity.PrimaryKeyLong;//当前Grain的key Console.WriteLine($"\n {id}收到SayHello消息 \n"); return Task.FromResult($"\n 大家好,我是{id} \n"); } }}
这里我使用了GrainReference.GrainIdentity.PrimaryKeyLong
,这个值就是当前Grain的idkey值,有了它Grain才能知道自己是谁. =_=!
Silo_ConsoleApp
using Grains;using Orleans;using Orleans.Configuration;using Orleans.Hosting;using System;using System.Net;using System.Threading.Tasks;namespace Silo_ConsoleApp{ class Program { static async Task Main(string[] args) { Console.WriteLine("开始启动Silo!"); try { var host = await StartSilo(); Console.WriteLine("Silo启动完成"); Console.WriteLine("\n\n 按回车键停止 \n\n"); Console.ReadLine(); await host.StopAsync();//停止当前Silo return; } catch (Exception ex) { Console.WriteLine(ex); return; } } /// <summary> /// 启动本地配置 /// </summary> /// <returns></returns> private static async Task<ISiloHost> StartSilo() { var host = new SiloHostBuilder() .UseLocalhostClustering() //配置Silo只使用开发集群,并监听本地主机。 .Configure<ClusterOptions>(options => { options.ClusterId = "dev"; options.ServiceId = "MyHost"; //获取或设置此服务的唯一标识符,该标识符应在部署和重新部署后仍然有效 }) .Configure<EndpointOptions>(options => options.AdvertisedIPAddress = IPAddress.Loopback)//配置Silo的端口 .ConfigureApplicationParts(parts => parts.AddApplicationPart(typeof(Student).Assembly).WithReferences()) .Build(); await host.StartAsync();//启动当前Silo. return host; } }}
先用本地开发配置
Client_ConsoleApp
using IGrains;using Orleans;using Orleans.Configuration;using System;using System.Threading.Tasks;namespace Client_ConsoleApp{ class Program { static async Task Main(string[] args) { Console.WriteLine("开始启动Silo!"); try { using (var client = await ConnectClient()) { Console.WriteLine("客户端已成功连接到Silo Host \n"); await DoClientWork(client); } } catch (Exception ex) { Console.WriteLine(ex); } Console.WriteLine("\n\n 按任意键退出 \n\n"); Console.ReadKey(); return; } private static async Task DoClientWork(IClusterClient client) { //从客户端调用Grain的示例 var student = client.GetGrain<IStudent>(321); var response = await student.SayHello(); Console.WriteLine("\n\n{0}\n\n", response); } /// <summary> /// 使用本地配置连接服务 /// </summary> /// <returns></returns> private static async Task<IClusterClient> ConnectClient() { IClusterClient client; client = new ClientBuilder() .UseLocalhostClustering() //配置客户端以连接到本地主机上的筒仓。 .Configure<ClusterOptions>(options => { options.ClusterId = "dev"; options.ServiceId = "MyHost"; }) .Build(); await client.Connect(); return client; } }}
同样适用本地配置
修改发布设置
.net core 的程序有个比较烦的地方,每次编译都会编译出来一大堆文件,看着心烦。
还好微软给了咱一个单文件发布的方法,可以把这些文件打到一个文件里,下面我来举个栗子
右键Silo_ConsoleApp
项目,选择发布,然后选择发布到本地文件夹,修改为如下配置:
然后点一下发布,咱们在选择的文件夹里就能看到它了:
Client_ConsoleApp
可以执行同样的操作
运行程序
咱们把Silo和Client程序都跑起来,注意,要先启动Silo程序,等待Silo启动成功后再启动Client。
运行效果如下:
便捷路由
