ABP微服务系列学习-搭建自己的微服务结构（一）
在原本的结构里面，由于默认服务引用的都是ABP原生的模块，所以结构目录里面没有包含modules目录，这里我们添加一个modules目录，用于存放我们的自定义模块。
在shared里面，我们再抽一个EventData的模块，用于消息队列共用数据实体。修改后结构如下图所示：
开始搭建
由于我们没有商业版的代码生成器，那就纯手工搭建这个结构了。这里我们使用VS Code作为编辑器配合dotnet cli操作
创建新的空白解决方案，后续通过再VS来编辑解决方案的内容。
dotnet new sln -n FunShow
然后在解决方案目录下创建目录
创建Shared项目
使用dotnet cli创建shared目录下的项目
dotnet new classlib -n FunShow.Shared.Hosting -f net7.0
dotnet new classlib -n FunShow.Shared.Hosting.AspNetCore -f net7.0
dotnet new classlib -n FunShow.Shared.Hosting.Gateways -f net7.0
dotnet new classlib -n FunShow.Shared.Hosting.Microservices -f net7.0
dotnet new classlib -n FunShow.Shared.Localization -f net7.0
dotnet new classlib -n FunShow.Shared.EventData -f net7.0
dotnet new console -n FunShow.DbMigrator -f net7.0
编辑.csproj文件

DbMigrator我们后续到数据迁移时再去完善
实现FunShow.Shared.Hosting
添加类FunShowSharedHostingModule.cs
using Volo.Abp.Autofac;
using Volo.Abp.Data;
using Volo.Abp.Modularity;
namespace FunShow.Shared.Hosting;
[DependsOn(
typeof(AbpAutofacModule),
typeof(AbpDataModule)
)]
public class FunShowSharedHostingModule : AbpModule
{
public override void PreConfigureServices(ServiceConfigurationContext context)
{
// https://www.npgsql.org/efcore/release-notes/6.0.html#opting-out-of-the-new-timestamp-mapping-logic
System.AppContext.SetSwitch("Npgsql.EnableLegacyTimestampBehavior", true);
}
public override void ConfigureServices(ServiceConfigurationContext context)
{
ConfigureDatabaseConnections();
}
private void ConfigureDatabaseConnections()
{
Configure<AbpDbConnectionOptions>(options =>
{
options.Databases.Configure("AdministrationService", database =>
{
database.MappedConnections.Add("AbpAuditLogging");
database.MappedConnections.Add("AbpPermissionManagement");
database.MappedConnections.Add("AbpSettingManagement");
database.MappedConnections.Add("AbpFeatureManagement");
});
options.Databases.Configure("IdentityService", database =>
{
database.MappedConnections.Add("AbpIdentity");
database.MappedConnections.Add("OpenIddict");
});
});
}
}
这里我打算用PGSQL，所以需要配置一下
System.AppContext.SetSwitch("Npgsql.EnableLegacyTimestampBehavior", true);
ConfigureDatabaseConnections方法里面作用是设置数据库连接字符串映射关系，把ABP基础模块的数据库映射到微服务对应数据库。目前配置2个基础服务相关的链接字符串。
实现FunShow.Shared.Hosting.AspNetCore
添加类FunShowSharedHostingAspNetCoreModule.cs
using System;
using Volo.Abp.AspNetCore.Serilog;
using Volo.Abp.Modularity;
using Volo.Abp.Swashbuckle;
namespace FunShow.Shared.Hosting.AspNetCore;
[DependsOn(
typeof(FunShowSharedHostingModule),
typeof(AbpAspNetCoreSerilogModule),
typeof(AbpSwashbuckleModule)
)]
public class FunShowSharedHostingAspNetCoreModule : AbpModule
{
}
添加类SwaggerConfigurationHelper.cs
using System.Collections.Generic;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.OpenApi.Models;
using Volo.Abp.Modularity;
namespace FunShow.Shared.Hosting.AspNetCore
{
public static class SwaggerConfigurationHelper
{
public static void Configure(
ServiceConfigurationContext context,
string apiTitle
)
{
context.Services.AddAbpSwaggerGen(options =>
{
options.SwaggerDoc("v1", new OpenApiInfo { Title = apiTitle, Version = "v1" });
options.DocInclusionPredicate((docName, description) => true);
options.CustomSchemaIds(type => type.FullName);
});
}
public static void ConfigureWithAuth(
ServiceConfigurationContext context,
string authority,
Dictionary<string, string> scopes,
string apiTitle,
string apiVersion = "v1",
string apiName = "v1"
)
{
context.Services.AddAbpSwaggerGenWithOAuth(
authority: authority,
scopes: scopes,
options =>
{
options.SwaggerDoc(apiName, new OpenApiInfo { Title = apiTitle, Version = apiVersion });
options.DocInclusionPredicate((docName, description) => true);
options.CustomSchemaIds(type => type.FullName);
});
}
}
}
添加类SerilogConfigurationHelper.cs
using System;
using System.IO;
using Microsoft.Extensions.Configuration;
using Serilog;
using Serilog.Events;
using Serilog.Sinks.Elasticsearch;
namespace FunShow.Shared.Hosting.AspNetCore
{
public static class SerilogConfigurationHelper
{
public static void Configure(string applicationName)
{
var configuration = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json")
.AddEnvironmentVariables()
.Build();
Log.Logger = new LoggerConfiguration()
#if DEBUG
.MinimumLevel.Debug()
#else
.MinimumLevel.Information()
#endif
.MinimumLevel.Override("Microsoft", LogEventLevel.Information)
.MinimumLevel.Override("Microsoft.EntityFrameworkCore", LogEventLevel.Warning)
.Enrich.FromLogContext()
.Enrich.WithProperty("Application", $"{applicationName}")
.WriteTo.Async(c => c.File("Logs/logs.txt"))
// .WriteTo.Elasticsearch(
// new ElasticsearchSinkOptions(new Uri(configuration["ElasticSearch:Url"]))
// {
// AutoRegisterTemplate = true,
// AutoRegisterTemplateVersion = AutoRegisterTemplateVersion.ESv6,
// IndexFormat = "Walk-log-{0:yyyy.MM}"
// })
.WriteTo.Async(c => c.Console())
.CreateLogger();
}
}
}
这里我们先注释掉写入ES的配置。先预留，后续有需要可以放开注释，或者配置其他日志记录方式。
实现FunShow.Shared.Hosting.Gateways
添加类FunShowSharedHostingGatewaysModule.cs
using FunShow.Shared.Hosting.AspNetCore;
using Microsoft.Extensions.DependencyInjection;
using Volo.Abp.Modularity;
namespace FunShow.Shared.Hosting.Gateways;
[DependsOn(
typeof(FunShowSharedHostingAspNetCoreModule)
)]
public class FunShowSharedHostingGatewaysModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
var configuration = context.Services.GetConfiguration();
context.Services.AddReverseProxy()
.LoadFromConfig(configuration.GetSection("ReverseProxy"));
}
}
添加类GatewayHostBuilderExtensions.cs
using Microsoft.Extensions.Configuration;
namespace Microsoft.Extensions.Hosting
{
public static class GatewayHostBuilderExtensions
{
public const string AppYarpJsonPath = "yarp.json";
public static IHostBuilder AddYarpJson(
this IHostBuilder hostBuilder,
bool optional = true,
bool reloadOnChange = true,
string path = AppYarpJsonPath)
{
return hostBuilder.ConfigureAppConfiguration((_, builder) =>
{
builder.AddJsonFile(
path: AppYarpJsonPath,
optional: optional,
reloadOnChange: reloadOnChange
)
.AddEnvironmentVariables();
});
}
}
}
这个类用于扩展IHostBuilder方法，配置网关读取配置文件，这里采用yarp作为网关组件，原商业版微服务模板采用的是ocelot。
添加类YarpSwaggerUIBuilderExtensions.cs，用于配置swagger
using System.Linq;
using Microsoft.AspNetCore.Builder;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Volo.Abp;
using Yarp.ReverseProxy.Configuration;
namespace FunShow.Shared.Hosting.Gateways
{
public static class YarpSwaggerUIBuilderExtensions
{
public static IApplicationBuilder UseSwaggerUIWithYarp(this IApplicationBuilder app,
ApplicationInitializationContext context)
{
app.UseSwagger();
app.UseSwaggerUI(options =>
{
var configuration = context.ServiceProvider.GetRequiredService<IConfiguration>();
var logger = context.ServiceProvider.GetRequiredService<ILogger<ApplicationInitializationContext>>();
var proxyConfigProvider = context.ServiceProvider.GetRequiredService<IProxyConfigProvider>();
var yarpConfig = proxyConfigProvider.GetConfig();
var routedClusters = yarpConfig.Clusters
.SelectMany(t => t.Destinations,
(clusterId, destination) => new {clusterId.ClusterId, destination.Value});
var groupedClusters = routedClusters
.GroupBy(q => q.Value.Address)
.Select(t => t.First())
.Distinct()
.ToList();
foreach (var clusterGroup in groupedClusters)
{
var routeConfig = yarpConfig.Routes.FirstOrDefault(q =>
q.ClusterId == clusterGroup.ClusterId);
if (routeConfig == null)
{
logger.LogWarning($"Swagger UI: Couldn't find route configuration for {clusterGroup.ClusterId}...");
continue;
}
options.SwaggerEndpoint($"{clusterGroup.Value.Address}/swagger/v1/swagger.json", $"{routeConfig.RouteId} API");
options.OAuthClientId(configuration["AuthServer:SwaggerClientId"]);
options.OAuthClientSecret(configuration["AuthServer:SwaggerClientSecret"]);
}
});
return app;
}
}
}
实现FunShow.Shared.Hosting.Microservices
添加类FunShowSharedHostingMicroservicesModule.cs
using Medallion.Threading;
using Medallion.Threading.Redis;
using Microsoft.AspNetCore.DataProtection;
using Microsoft.Extensions.DependencyInjection;
using FunShow.Shared.Hosting.AspNetCore;
using StackExchange.Redis;
using Volo.Abp.AspNetCore.MultiTenancy;
using Volo.Abp.BackgroundJobs.RabbitMQ;
using Volo.Abp.Caching;
using Volo.Abp.Caching.StackExchangeRedis;
using Volo.Abp.DistributedLocking;
using Volo.Abp.EventBus.RabbitMq;
using Volo.Abp.Modularity;
using Volo.Abp.MultiTenancy;
using Volo.Abp.EntityFrameworkCore;
namespace FunShow.Shared.Hosting.Microservices;
[DependsOn(
typeof(AbpEntityFrameworkCoreModule),
typeof(FunShowSharedHostingAspNetCoreModule),
typeof(AbpBackgroundJobsRabbitMqModule),
typeof(AbpAspNetCoreMultiTenancyModule),
typeof(AbpDistributedLockingModule),
typeof(AbpEventBusRabbitMqModule),
typeof(AbpCachingStackExchangeRedisModule)
)]
public class FunShowSharedHostingMicroservicesModule: AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
var configuration = context.Services.GetConfiguration();
var hostingEnvironment = context.Services.GetHostingEnvironment();
Configure<AbpMultiTenancyOptions>(options =>
{
options.IsEnabled = true;
});
Configure<AbpDistributedCacheOptions>(options =>
{
options.KeyPrefix = "FunShow:";
});
var redis = ConnectionMultiplexer.Connect(configuration["Redis:Configuration"]);
context.Services
.AddDataProtection()
.SetApplicationName("FunShow")
.PersistKeysToStackExchangeRedis(redis, "FunShow-Protection-Keys");
context.Services.AddSingleton<IDistributedLockProvider>(_ =>
new RedisDistributedSynchronizationProvider(redis.GetDatabase()));
}
}
添加JWT配置类JwtBearerConfigurationHelper.cs
using System;
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.Extensions.DependencyInjection;
using Volo.Abp.Modularity;
namespace FunShow.Shared.Hosting.Microservices
{
public static class JwtBearerConfigurationHelper
{
public static void Configure(
ServiceConfigurationContext context,
string audience)
{
var configuration = context.Services.GetConfiguration();
context.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddJwtBearer(options =>
{
options.Authority = configuration["AuthServer:Authority"];
options.RequireHttpsMetadata = Convert.ToBoolean(configuration["AuthServer:RequireHttpsMetadata"]);
options.Audience = audience;
});
}
}
}
实现FunShow.Shared.Localization
在项目中添加nuget包Microsoft.Extensions.FileProviders.Embedded，此包是实现访问内嵌资源文件的根本。
然后在项目文件的标签中添加xml配置
<RootNamespace>FunShow</RootNamespace>
<GenerateEmbeddedFilesManifest>true</GenerateEmbeddedFilesManifest>
如果没有上述配置，系统是无法读取多语言配置的。
创建Localization目录，添加类FunShowResource.cs
using Volo.Abp.Localization;
namespace FunShow.Localization
{
[LocalizationResourceName("FunShow")]
public class FunShowResource
{
}
}
在Localization目录创建FunShow子目录，添加en.json和zh-Hans.json文件
{
"culture": "en",
"texts": {
"Menu:Home": "Home",
"Login": "Login",
"Menu:Dashboard": "Dashboard"
}
}
{
"culture": "zh-Hans",
"texts": {
"Menu:Home": "家",
"Login": "登录",
"Menu:Dashboard": "仪表盘"
}
}
添加类FunShowSharedLocalizationModule.cs
using FunShow.Localization;
using Volo.Abp.Localization;
using Volo.Abp.Modularity;
using Volo.Abp.Validation;
using Volo.Abp.Validation.Localization;
using Volo.Abp.VirtualFileSystem;
namespace FunShow.Shared.Localization;
[DependsOn(
typeof(AbpValidationModule)
)]
public class FunShowSharedLocalizationModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
Configure<AbpVirtualFileSystemOptions>(options =>
{
options.FileSets.AddEmbedded<FunShowSharedLocalizationModule>();
});
Configure<AbpLocalizationOptions>(options =>
{
options.Resources
.Add<FunShowResource>("en")
.AddBaseTypes(
typeof(AbpValidationResource)
).AddVirtualJson("/Localization/FunShow");
options.DefaultResourceType = typeof(FunShowResource);
});
}
}
实现FunShow.Shared.EventData
添加类FunShowSharedEventDataModule.cs
using Volo.Abp.Modularity;
namespace FunShow.Shared.EventData;
public class FunShowSharedEventDataModule: AbpModule
{
}
至此我们完成了Shared项目的初始化，后续有一些共用的修改再返回来修改对应的项目。
下一章我们来实现基础的AdministrationService和IdentityService
