Fireasy3 揭秘 -- 使用 SourceGeneraor 改进服务发现

[*]Fireasy3 揭秘 -- 使用 SourceGeneraor 实现动态代理(AOP)
　　在 Fireasy3 揭秘 -- 依赖注入与服务发现 这篇中，我们通过遍列程序集中的所有类，来查找三个类型的服务接口，这样应用在启动时会消耗一定的时间来处理这些事情。今天，我们将用 ISourceGenerator 来对它进行改进。
　　ISourceGenerator 是 Microsoft.CodeAnalysis.Analyzers 中的一项技术，它是基于代码分析的原理，在语法树中查找所需要的内容，通过这些内容再构造一段源代码，使得我们在编译程序集的时候，把这些代码一并编译进去。使用它的好处在于，它是在编译时生成的，而不像 Emit 或其他反射等方法来构建的动态代码一样，在运行时将耗费一定的性能。
　　需要新建一个 .net standard 2.0 的项目，并引入 Microsoft.CodeAnalysis.Analyzers 和 Microsoft.CodeAnalysis.CSharp，见 Fireasy.Common.Analyzers。
　　在项目里添加一个类，实现 ISourceGenerator 接口，如下：
   
    public class ServiceDiscoverGenerator : ISourceGenerator
    {
<Project Sdk="Microsoft.NET.Sdk">
<ItemGroup>
    <ProjectReference Include="..\..\libraries\Fireasy.Common.Analyzers\Fireasy.Common.Analyzers.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />
</ItemGroup>
</Project>void ISourceGenerator.Initialize(GeneratorInitializationContext context)
<Project Sdk="Microsoft.NET.Sdk">
<ItemGroup>
    <ProjectReference Include="..\..\libraries\Fireasy.Common.Analyzers\Fireasy.Common.Analyzers.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />
</ItemGroup>
</Project>{

    <ProjectReference Include="..\..\libraries\Fireasy.Common.Analyzers\Fireasy.Common.Analyzers.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />

</Project>    Debugger.Launch();
<Project Sdk="Microsoft.NET.Sdk">
<ItemGroup>
    <ProjectReference Include="..\..\libraries\Fireasy.Common.Analyzers\Fireasy.Common.Analyzers.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />
</ItemGroup>
</Project>    context.RegisterForSyntaxNotifications(() => new ServiceDiscoverSyntaxReceiver());
<Project Sdk="Microsoft.NET.Sdk">
<ItemGroup>
    <ProjectReference Include="..\..\libraries\Fireasy.Common.Analyzers\Fireasy.Common.Analyzers.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />
</ItemGroup>
</Project>}

<Project Sdk="Microsoft.NET.Sdk">
<ItemGroup>
    <ProjectReference Include="..\..\libraries\Fireasy.Common.Analyzers\Fireasy.Common.Analyzers.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />

</Project>void ISourceGenerator.Execute(GeneratorExecutionContext context)
<Project Sdk="Microsoft.NET.Sdk">

</ItemGroup>
</Project>}
    }　　Initialize 方法用于初始化生成器，使用 RegisterForSyntaxNotifications 方法向上下文注入一个语法接收器，以便用来分析语法树。这里的语法接收器有两种，分别是 ISyntaxReceiver 和 ISyntaxContextReceiver，后者可以从上下文中获取到 SemanticModel 对象，这样的话能够从语法节点中获取到定义的符号模型。使用符号模型相对于语法节点来说要更方便一些。下面是基于 ISyntaxContextReceiver 接口的语法接收器。
    internal class ServiceDiscoverSyntaxReceiver : ISyntaxContextReceiver

    }　　OnVisitSyntaxNode 方法正如 lambda 表达式树的 ExpressionVisitor 一样，语法树中的每一个节点都会被它访问到。我们需要分析的是类，因此只需要处理 ClassDeclarationSyntax 语法即可。AnalyseClassSyntax 方法如下：

</Project>}　　到这里，源代码生成器就算是完成了，那接下来怎么让它工作呢？
　　首先，我们需要找到一个“宿主”，我之所以这么称呼，是因为 nuget 打包时，需要将分析器依附到一个包内，因此我选择 Fireasy.Common，在 Fireasy.Common 的项目文件中，加下以下一段代码，它的目的是当 Fireasy.Common 打包时，Fireasy.Common.Analyzers.dll 会自动打包到 analyzers 目录下，引用 Fireasy.Common 包时，会自动使用该分析器来生成代码。如下：
<Project Sdk="Microsoft.NET.Sdk">
<Target Name="_IncludeAllDependencies" BeforeTargets="_GetPackageFiles">
    <ItemGroup>
<Project Sdk="Microsoft.NET.Sdk">
<ItemGroup>
    <ProjectReference Include="..\..\libraries\Fireasy.Common.Analyzers\Fireasy.Common.Analyzers.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />
</ItemGroup>
</Project><None Include="..\Fireasy.Common.Analyzers\bin\$(Configuration)\**\*.dll" Pack="True" PackagePath="analyzers\dotnet\cs" />
    </ItemGroup>
</Target>
</Project>　　我们测试的时候，因为是直接引用的项目，因此需要引用包含分析器的项目，而且要加上 OutputItemType 和 ReferenceOutputAssembly，如下：
<Project Sdk="Microsoft.NET.Sdk">
<ItemGroup>
    <ProjectReference Include="..\..\libraries\Fireasy.Common.Analyzers\Fireasy.Common.Analyzers.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />
</ItemGroup>
</Project>　　好了，编译测试项目，使用 ILSpy 反编译 dll 文件，你会发现，实现了 ISingletonService、ITransientService 或 IScopedService 的类自动注册进来了：
// __ServiceDiscoverNs.__ServiceDiscoverServicesDeployer
using Fireasy.Common.DependencyInjection;
using Fireasy.Common.Tests;
using Microsoft.Extensions.DependencyInjection;

void IServicesDeployer.Configure(IServiceCollection services)
{
        services.AddSingleton(typeof(DependencyInjectionTests.ITestSingletonService), typeof(DependencyInjectionTests.TestSingletonServiceImpl));
        services.AddTransient(typeof(DependencyInjectionTests.ITestTransientService), typeof(DependencyInjectionTests.TestTransientServiceImpl));
        services.AddScoped(typeof(DependencyInjectionTests.ITestScopedService), typeof(DependencyInjectionTests.TestScopedServiceImpl));
        services.AddTransient(typeof(DependencyInjectionTests.ITestWithRegisterAttr), typeof(DependencyInjectionTests.TestWithRegisterAttrImpl));
        services.AddTransient(typeof(DependencyInjectionTests.TestWithRegisterAttrNonIntefaceImpl), typeof(DependencyInjectionTests.TestWithRegisterAttrNonIntefaceImpl));
        services.AddTransient(typeof(DependencyInjectionTests.IGenericService<, >), typeof(DependencyInjectionTests.GenericService<, >));
        services.AddTransient(typeof(DependencyInjectionTests.TestDynamicProxyClass), typeof(DependencyInjectionTests.TestDynamicProxyClass));
        services.AddTransient(typeof(ObjectActivatorTests.ITestService), typeof(ObjectActivatorTests.TestService));
}　　另外还有一个小窍门，在测试项目的“依赖项”--“分析器”下，你会看到一个属于自己的分析器，依次展开，也会找到所生成的那个代码文件。
