Lage.AutoInject.Generator

NuGet: Lage.AutoInject.Generator · 仓库: GitHub · 许可证: MIT

基于 Roslyn 增量生成器的零反射 · AOT 兼容自动依赖注入工具。对实现接口的类标记 [AutoInject]，编译时自动生成 AddAutoInject(this IServiceCollection) 扩展方法，入口调用一次即可批量注册所有被标记的接口。要求 .NET Core 3.0+ / .NET 5+。

安装

dotnet add package Lage.AutoInject.Generator

使用

标记实现类

using Lage.AutoInject.Core;

// 方式一：默认注册到类实现的第一个接口，生命周期 Scoped
[AutoInject]
public class Foo : IFoo { }

// 方式二：泛型版本显式指定注入接口，生命周期 Transient
[AutoInject<IBar>(ServiceLifetime.Transient)]
public class Bar : IBar { }

// 方式三：非泛型 + ServiceType 属性指定接口，生命周期 Singleton
[AutoInject(ServiceLifetime.Singleton, ServiceType = typeof(IBaz))]
public class Baz : IBaz { }

入口注册

using Lage.AutoInject; // 扩展方法命名空间
using Microsoft.Extensions.DependencyInjection;

var services = new ServiceCollection();
services.AddAutoInject(); // 一次调用批量注册

var provider = services.BuildServiceProvider();
var foo = provider.GetRequiredService<IFoo>(); // 已注入

生成的扩展方法形如：

public static IServiceCollection AddAutoInject(this IServiceCollection services)
{
    services = AddScoped<IFoo, Foo>(services);
    services = AddTransient<IBar, Bar>(services);
    services = AddSingleton<IBaz, Baz>(services);
    return services;
}

服务接口解析优先级

  1. 泛型版本 [AutoInject<T>] → T
  2. 非泛型且设置 ServiceType 属性 → 该类型
  3. 均未指定 → 类实现的第一个接口

生命周期

LifeTime 默认 Scoped，可通过构造函数参数指定 ServiceLifetime.Singleton/Scoped/Transient。

编译诊断

ID 严重性 触发条件
AUTOINJ001 Error 标记 [AutoInject] 的类未实现任何接口且未指定服务接口
AUTOINJ002 Error 泛型参数不是接口
AUTOINJ003 Error 指定的接口与实现类无实现/继承关系
