ASP.NET Core 项目实战（接口层和实现层）

接口层和实现层

1.创建接口层(Interface) 和 实现层(Service)

2. 编写 注册接口和实现之间的关系

using Autofac;
using System.Reflection;

namespace WebApi.Config
{
    /// 

    /// 
    /// 
    public class AutofacModuleRegister:Autofac.Module
    {
        // 注册接口和实现之间的关系
        protected override void Load(ContainerBuilder builder)
        {
            Assembly interfaceAssembly= Assembly.Load("Interface");
            Assembly serviceAssembly = Assembly.Load("Service");
            builder.RegisterAssemblyTypes(interfaceAssembly, serviceAssembly).AsImplementedInterfaces();
        }

    }
}

3.配置注册接口和实现层=》HostBuilderExtend

using Autofac;
using Autofac.Extensions.DependencyInjection;
using SqlSugar;
using System.Runtime.CompilerServices;

namespace WebApi.Config
{
    /// 

    /// 注册类-扩展
    /// 
    public static class HostBuilderExtend
    {
        public static void Register(this WebApplicationBuilder app)
        {
            // 1. nuGet 安装 autofac
            app.Host.UseServiceProviderFactory(new AutofacServiceProviderFactory());
            app.Host.ConfigureContainer(builder =>
            {
                #region 注册 sqlsugar
                builder.Register(context =>
                {
                    SqlSugarClient db = new SqlSugarClient(new ConnectionConfig()
                    {
                        //数据库配置地址
                        ConnectionString = "Server=;Database=zxAdminDb;Uid=sa;Pwd=root",
                        DbType = DbType.SqlServer,
                        IsAutoCloseConnection = true
                    });
                    //支持SQL 语句的输出，方便排查问题
                    db.Aop.OnLogExecuted = (sql, par) =>
                    {
                        Console.WriteLine("\r\n");
                        Console.WriteLine($"{DateTime.Now.ToString("yyyyMMdd HH:mm:ss")},Sql语句:{sql}");
                        Console.WriteLine("===================================================");
                    };
                    return db; 
                });
                #endregion

                // 注册接口和实现层
                builder.RegisterModule(new AutofacModuleRegister());

            });
        }

    }
}
