Cuture.Extensions.Modularity

1. Intro

围绕 Microsoft.Extensions.DependencyInjection.Abstractions 为核心的.Net模块化开发库.

2. Features

  • 支持异步的模块配置方法;
  • 支持基于特性标注的服务自动注入(默认不支持基于继承的服务自动注入);
  • 基本和Abp的模块实现方法相同;
  • 可拓展的模块加载源,已实现基于TypeAssemblyFileDirectory的模块加载;
  • IOptions<TOptions>自动绑定;
  • 可集成其它模块系统的模块(如Abp),详见示例代码;
  • 主项目只依赖Microsoft.Extensions.DependencyInjection.Abstractions,Hosting项目额外依赖Hosting.AbstractionsConfiguration.BinderOptions
  • Mermaid生成工具,方便查看模块依赖关系;

Package Description
Cuture.Extensions.Modularity 模块化的核心库
Cuture.Extensions.Modularity.Hosting 对Host的模块化支持库,用于在通用主机中加载模块

3. 如何使用

3.1 安装Nuget

Install-Package Cuture.Extensions.Modularity

3.2 实现一个模块

[DependsOn(
    typeof(DependsSampleModule1),
    typeof(DependsSampleModule2)
    )]  //定义依赖的模块
[AutoRegisterServicesInAssembly]
public class SampleModule : AppModule
{
    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        //进行模块需要的配置
    }
}
  • [DependsOn]:声明此模块依赖的模块,加载顺序与声明顺序相同;(可选)
  • [AutoRegisterServicesInAssembly]:有此特性的模块将会自动将所在程序集中使用ExportServices标记的导出服务注入到DI容器;(可选)
    • 1.1.6之后默认自动注册,使用[DisableAssemblyServicesRegister]特性进行手动关闭
  • 继承AppModule:标准的模块只需要继承IAppModule即可。如果需要单独的配置,则可以单独实现IPreConfigureServicesIConfigureServicesIPostConfigureServicesIOnPreApplicationInitializationIOnApplicationInitializationIOnPostApplicationInitializationIOnApplicationShutdown以在对应的时机进行配置,或直接继承AppModule并重写对应的方法;所有方法都有异步版本IPreConfigureServicesAsyncIConfigureServicesAsyncIPostConfigureServicesAsyncIOnPreApplicationInitializationAsyncIOnApplicationInitializationAsyncIOnPostApplicationInitializationAsyncIOnApplicationShutdownAsync,或直接继承AsyncAppModule

3.3 直接通过DI容器使用模块

可能需要安装Microsoft.Extensions.DependencyInjection包,视主项目而定
var services = new ServiceCollection();

//加载模块
services.LoadModule<SampleModule>() //直接从类型加载
        .LoadModuleFile(modulePath) //从文件加载
        .LoadModuleDirectory(source =>
        {
            source.SearchDepth = 5;    //设置文件夹搜索深度
        }, moduleDirectory)  //从文件夹加载
        .ModuleLoadComplete()   //必须调用此方法,以确认模块加载完成

using (var serviceProvider = services.BuildServiceProvider())
{
    //必须调用此方法,以初始化模块
    serviceProvider.InitializationModulesWithOutHostLifetime();

    //这里使用初始化了模块的serviceProvider

    //关闭模块
    serviceProvider.ShutdownModules();
}

Note:

  • 直接使用DI容器时,不会在控制台等关闭时,自动调用模块结束方法(使用Host时会),需要手动调用;

3.4 通过通用主机使用模块 (Console、Asp .net Core...)

1. 安装Hosting拓展库
Install-Package Cuture.Extensions.Modularity.Hosting
2. 在主机构建时配置模块加载
Host.CreateDefaultBuilder(args)
    .LoadModule<SampleModule>() //直接从类型加载
    .LoadModuleFile(modulePath) //从文件加载
    .LoadModuleDirectory(source =>
    {
        source.SearchDepth = 5;    //设置文件夹搜索深度
    }, moduleDirectory)  //从文件夹加载
    .UseConsoleLifetime()
    .InitializationModules()    //必须调用此方法,以初始化模块
    .Run();
  • 也可以通过配置主机DI容器的方法来使用

更多细节详见示例代码;

3.5 服务导出

  • 需要为类型所在程序集模块标记特性[AutoRegisterServicesInAssembly]
[ExportServices(ServiceLifetime.Singleton, AddDIMode.Replace, typeof(IHello))]
public class Hello : IHello
{
    public string SayHello()
    {
        return "Hello";
    }
}

示例代码会自动将Hello类型以单例模式注册为IHello服务,并在注入时使用Replace方法。

参数:

  • ServiceLifetime:注册的生命周期类型;
  • AddDIMode:注册的方法,包括AddTryAddReplace

除示例的ExportServices外,还有ExportSingletonServicesExportScopedServicesExportTransientServices等多个拓展特性的重载实现;

IOptions<TOptions>自动绑定

  • 自动查找模块中继承了IOptions<TOptions>的类;
  • 使用其完整名称为路径,在IConfiguration查找节点,并绑定值;
  • A 类命名空间为 B.C.D.E.F ,则IConfiguration查找路径为 B:C:D:E:F:A
  • Note: 构建过程中必须有可访问的IConfiguration !!! 详见示例项目;

示例配置代码:

  • 在构建中调用 AutoBindModuleOptions() 方法即可;
Host.CreateDefaultBuilder(args)
    .ConfigureHostConfiguration(builder => builder.AddJsonFile("appsettings.Development.json"))
    .LoadModule<HostSampleModule>()
    .AutoBindModuleOptions()    //自动使用 IConfiguration 绑定模块中继承了 IOptions<TOptions> 的类
    .UseConsoleLifetime()
    .InitializationModules()
    .Run();

集成其它模块系统的模块

参考示例项目OtherModuleSystemAdaptSample

其它

获取依赖的Mermaid字符串

var abpModuleDescriptors = AppModuleDependencyUtil.FindAllDependedModuleDescriptors(typeof(XXXModule));
var mermaidString = abpModuleDescriptors.ToMermaidString();

然后将mermaidString复制到支持mermaid的编辑器就能查看模块依赖关系了。
