IoC容器是一种设计模式,它可以管理应用程序中的对象依赖关系。它可以自动创建和注入对象,从而减少了代码的耦合度和重复性。
Autofac是Microsoft .NET的IoC容器。它管理类之间的依赖关系,以便应用程序在大小和复杂性增加时易于更改。这是通过将常规 .NET 类视为组件来实现的。
Autofac的官网:https://autofac.org/
Autofac的源码网址:https://gitee.com/dennisdyh/Autofac.Extensions.DependencyInjection
Autofac.Extensions.DependencyInjection
在Program注入Autofac服务
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.ConfigureKestrel(serverOptions =>
{
serverOptions.Limits.MaxRequestBodySize = 10485760;
// Set properties and call methods on options
});
webBuilder.UseKestrel().UseUrls("http://*:9991");
webBuilder.UseIIS();
webBuilder.UseStartup<Startup>();
}).UseServiceProviderFactory(new AutofacServiceProviderFactory());//设置工厂来替换实例
在Startup中增加ConfigureContainer方法,用来配置映射关系
public void ConfigureContainer(ContainerBuilder builder)
{
Services.AddModule(builder, Configuration);
}
使用了Autofac以后,在IServiceCollection中注入的服务,也能生效;因为Autofac是先接受了所有的来自于IServiceCollection的服务映射后,再去读取ConfigureContainer方法中配置的映射。
AddModule包含了反射注入容器和一堆服务注入容器
// private static bool _isMysql = false;
public static IServiceCollection AddModule(this IServiceCollection services, ContainerBuilder builder, IConfiguration configuration)
{
//services.AddSession();
//services.AddMemoryCache();
//初始化配置文件
AppSetting.Init(services, configuration);
Type baseType = typeof(IDependency);
var compilationLibrary = DependencyContext.Default
.RuntimeLibraries
.Where(x => !x.Serviceable
&& x.Type == "project")
.ToList();
var count1 = compilationLibrary.Count;
List<Assembly> assemblyList = new List<Assembly>();
foreach (var _compilation in compilationLibrary)
{
try
{
assemblyList.Add(AssemblyLoadContext.Default.LoadFromAssemblyName(new AssemblyName(_compilation.Name)));
}
catch (Exception ex)
{
Console.WriteLine(_compilation.Name + ex.Message);
}
}
builder.RegisterAssemblyTypes(assemblyList.ToArray())
.Where(type => baseType.IsAssignableFrom(type) && !type.IsAbstract)
.AsSelf().AsImplementedInterfaces()
.InstancePerLifetimeScope();
builder.RegisterType<UserContext>().InstancePerLifetimeScope();
builder.RegisterType<ActionObserver>().InstancePerLifetimeScope();
//model校验结果
builder.RegisterType<ObjectModelValidatorState>().InstancePerLifetimeScope();
string connectionString = DBServerProvider.GetConnectionString(null);
if (DBType.Name == DbCurrentType.MySql.ToString())
{
//增加dapper对mysql字段Guid映射
SqlMapper.AddTypeHandler(new DapperParseGuidTypeHandler());
SqlMapper.RemoveTypeMap(typeof(Guid?));
//services.AddDbContext<SysDbContext>();
//mysql8.x的版本使用Pomelo.EntityFrameworkCore.MySql 3.1会产生异常,需要在字符串连接上添加allowPublicKeyRetrieval=true
services.AddDbContextPool<SysDbContext>(optionsBuilder => { optionsBuilder.UseMySql(connectionString); }, 64);
services.AddDbContextPool<ServiceDbContext>(optionsBuilder => { optionsBuilder.UseMySql(connectionString); }, 64);
services.AddDbContextPool<ReportDbContext>(optionsBuilder => { optionsBuilder.UseMySql(connectionString); }, 64);
}

{

services.AddDbContextPool<ServiceDbContext>(optionsBuilder => { optionsBuilder.UseNpgsql(connectionString); }, 64);

services.AddDbContextPool<ServiceDbContext>(optionsBuilder => { optionsBuilder.UseSqlServer(connectionString); }, 64);
services.AddDbContextPool<ReportDbContext>(optionsBuilder => { optionsBuilder.UseSqlServer(connectionString); }, 64);
}
//启用缓存
if (AppSetting.UseRedis)

builder.RegisterType<RedisCacheService>().As<ICacheService>().SingleInstance();

builder.RegisterType<MemoryCacheService>().As<ICacheService>().SingleInstance();
