首先得先了解并熟悉一下springcloud，并手动去搭建一个服务中心，也可参照 。

如果是.net core的话，实现注册也是没有问题的，网上教程很多，可自行度娘。

最难的就是基于Framework的项目怎么实现注册，跟core的实现方式区别还是蛮大的，研究过程中也有不少坑。

下面就分享一下我踩完坑之后初步总结的实现步骤：

1.用VS2017或者其他创建NF4.5+的webAPI项目(webAPI的结构基本是保持MVC一致的，所以MVC项目基本也能按这个步骤来的)

2.在项目根目录内新建文件appsettings.json（这个文件主要是配置服务中心eurke地址等信息的):

{  "spring": {    "application": {      "name": "demoService"    }  },  "eureka": {    "client": {      "serviceUrl": "http://localhost:8761/eureka/",//服务中心地址      "shouldFetchRegistry": false,      "shouldRegisterWithEureka": true,//是否允许注册到服务中心        "validate_certificates": false    },    "instance": {      "port": 3001       }  },  "Logging": {    "IncludeScopes": false,    "LogLevel": {      "Default": "Debug",      "Pivotal": "Debug",      "Steeltoe": "Debug"    }  }}

 

 

3.在项目文件夹App_Start下创建ApplicationConfig.cs：

 

 

public static class ApplicationConfig    {​        public static IConfigurationRoot Configuration { get; set; }​        public static void RegisterConfig(string environment)        {             // Set up configuration sources.            var builder = new ConfigurationBuilder()                .SetBasePath(GetContentRoot())                .AddJsonFile("appsettings.json", optional: false, reloadOnChange: false)                .AddJsonFile($"appsettings.{environment}.json", optional: true)                .AddCloudFoundry()                .AddEnvironmentVariables();​            Configuration = builder.Build();        }​        public static string GetContentRoot()        {            var basePath = (string)AppDomain.CurrentDomain.GetData("APP_CONTEXT_BASE_DIRECTORY") ??               AppDomain.CurrentDomain.BaseDirectory;            return Path.GetFullPath(basePath);        }    }

 

 

注意这里需要添加的引用：

using Microsoft.Extensions.Configuration;using Steeltoe.Extensions.Configuration.CloudFoundry;

这两个是需要在引用点右键选择NuGet程序包里添加的。

 

4.修改Global.asax文件，在Application_Start()内加入代码：

GlobalConfiguration.Configure(WebApiConfig.Register);​ var config = GlobalConfiguration.Configuration;​// Build application configuration ApplicationConfig.RegisterConfig("development");​ var builder = new ContainerBuilder();​// Add Microsoft Options to container  builder.RegisterOptions();​// Add Microsoft Logging to container  builder.RegisterLogging(ApplicationConfig.Configuration);​// Add Console logger to container  builder.RegisterConsoleLogging();​// Register your Web API controllers.  builder.RegisterApiControllers(Assembly.GetExecutingAssembly());​// Register IDiscoveryClient, etc.  builder.RegisterDiscoveryClient(ApplicationConfig.Configuration);​// Initialize and Register FortuneContext  builder.RegisterInstance(SampleData.InitializeFortunes()).SingleInstance();​// Register FortuneRepository  builder.RegisterType
           
            ().As
            
             ().SingleInstance();​  var container = builder.Build();  config.DependencyResolver = new AutofacWebApiDependencyResolver(container);​// Get a logger from container  var logger = container.Resolve 
             
              
               >();​  logger.LogInformation("Finished container build, starting background services");​// Start the Discovery client background thread  container.StartDiscoveryClient();​  logger.LogInformation("Finished starting background services");
              
             
            
           

 

添加引用：

using Autofac;using Autofac.Integration.WebApi;using Microsoft.Extensions.Logging;using Microsoft.Extensions.Logging.Console;using Pivotal.Discovery.Client;using Steeltoe.Common.Discovery;using Steeltoe.Common.Logging.Autofac;using Steeltoe.Common.Options.Autofac;using System;using System.Diagnostics;using System.Reflection;using System.Web.Http;
