.net core 3.1添加Autofac容器详解

.net core 3.1添加Autofac容器

交流QQ群:555913397 有什么问题可以加群大家一起交流

1.引用nuget包

1.1 Autofac
1.2 Autofac.Extensions.DependencyInjection

2. 在Program.cs添加Autofac服务提供工厂

public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup();
                }).UseServiceProviderFactory(new AutofacServiceProviderFactory());

2.1添加这段代码UseServiceProviderFactory(new AutofacServiceProviderFactory())

3.在Startup.cs添加容器注册

pulic void ConfigureContainer(ContainerBuilder builder){
    //这里添加注册容器,可以直接注册也可以注册Module
    //1.注册Module方式,下面的AtuofacModule是自己写的类,名字可以随意取.
    builder.RegisterModule(new AutofacModule());
    //2.直接注册容器
    builder.RegisterType().As().AsImplementedInterfaces();
    //2.1注册程序集
    Assembly serviceAssembly = Assembly.Load("程序集名称");
    Assembly InterfaceAssembly = Assembly.Load("程序集名称");
    builder.RegisterAssemblyTypes(serviceAssembly,InterfaceAssembly)
    .where(x=>x.Name.EndWith("AppService",StringComparison.OrdinalIgnoreCase)
    .AsImplementedInterfaces();
}

4.Autofac Module类

public class AutofacModule : Module{
    protected ovrride void Load(ContainerBuilder builder){
        //这里添加注册容器,可以直接注册也可以注册Module
        //1.注册Module方式,下面的AtuofacModule是自己写的类,名字可以随意取.
        builder.RegisterModule(new AutofacModule());
        //2.直接注册容器
        builder.RegisterType().As().AsImplementedInterfaces();
        //2.1注册程序集
        Assembly serviceAssembly = Assembly.Load("程序集名称");
        Assembly InterfaceAssembly = Assembly.Load("程序集名称");
        builder.RegisterAssemblyTypes(serviceAssembly,InterfaceAssembly)
        .where(x=>x.Name.EndWith("AppService",StringComparison.OrdinalIgnoreCase)
        .AsImplementedInterfaces();
        }
}
