  • spring cloud + .net core实现微服务架构

    1.新建spring boot项目

    2.添加spring-cloud-starter-eureka-server依赖(需提供版本信息)

    <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-eureka-server -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-eureka-server</artifactId>
                <version>1.4.4.RELEASE</version>
            </dependency>

    3.设置程序属性信息

    spring.application.name=myservicehub
    server.port=5000
    
    #强制不注册到注册服务器
    eureka.client.register-with-eureka=false
    eureka.client.fetch-registry=false
    
    #注册中心地址
    eureka.client.serviceUrl.defaultZone=http://localhost:${server.port}/eureka/
    
    #驱逐下线的服务,间隔,5秒,默认是60,建议开发和测试环境配置
    #org.springframework.cloud.netflix.eureka.server.EurekaServerConfigBean.evictionIntervalTimerInMs
    eureka.server.evictionIntervalTimerInMs=5000

    4.在启动类添加注解

    @EnableEurekaServer
    @SpringBootApplication
    public class ServicehubApplication {}

    5.新建.net core webapi,并安装Pivotal.Discovery.Client nuget包

    Install-Package Pivotal.Discovery.Client
    public class Program
        {
            public static void Main(string[] args)
            {
                BuildWebHost(args).Run();
            }
    
            public static IWebHost BuildWebHost(string[] args) =>
                WebHost.CreateDefaultBuilder(args)
                    .UseStartup<Startup>()
                    .UseUrls("http://*:5001")
                    .Build();
        }
    public class Startup
        {
            public Startup(IConfiguration configuration)
            {
                Configuration = configuration;
            }
    
            public IConfiguration Configuration { get; }
    
            // This method gets called by the runtime. Use this method to add services to the container.
            public void ConfigureServices(IServiceCollection services)
            {
                services.AddDiscoveryClient(Configuration);
                services.AddMvc();
            }
    
            // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
            public void Configure(IApplicationBuilder app, IHostingEnvironment env)
            {
                if (env.IsDevelopment())
                {
                    app.UseDeveloperExceptionPage();
                }
    
                app.UseMvc();
                app.UseDiscoveryClient();
            }
        }

    6.appsettings.json中,注册服务到eureka-server

    {
    "Logging": {
        "IncludeScopes": false,
        "LogLevel": {
            "Default": "Warning"
        }
    },
    "spring": {
        "application": {
            "name": "serviceone"
        }
    },
    "eureka": {
      "client": {
        "serviceUrl": "http://localhost:5000/eureka/",
        "shouldFetchRegistry": false,
        "shouldRegisterWithEureka": true
      },
        "instance": {
            "port": 5001
        }
    }
    }
