使用.NET8实现Web API的项目实践

//第2步：设置第三方ORM-SQLSugar

//注册上下文
builder.Services.AddHttpContextAccessor();
//注册SqlSugar用AddScoped
builder.Services.AddScoped<ISqlSugarClient>(s =>
{
    //Scoped用SqlSugarClient 
    SqlSugarClient sqlSugar = new SqlSugarClient(new ConnectionConfig()
    {
        DbType = SqlSugar.DbType.Oracle,
        ConnectionString = builder.Configuration["DBConnectStr"],//在appsettings.json配置文件中的字符串设置
        IsAutoCloseConnection = true,
    },
   db =>
   {
       db.Aop.OnLogExecuting = (sql, pars) =>
       {
           //可以进行日志记录之类的工作

       };
   });
    return sqlSugar;
});

builder.Host.UseServiceProviderFactory(new AutofacServiceProviderFactory());
builder.Host.ConfigureContainer<ContainerBuilder>(b =>
{
    b.RegisterModule<AutofacModuleRegister>();
});

 public class AutofacModuleRegister: Autofac.Module
 {
     /// <summary>
     /// 自动加载注册程序集
     /// </summary>
     /// <param name="builder"></param>
     protected override void Load(ContainerBuilder builder)
     {
         var basePath = AppContext.BaseDirectory;

         #region 带有接口层的服务注入
         //服务注入
         List<string> dllServiceFiles = new List<string>()
         {
                 "TsinghuaNet8WebAPI.Dl.dll",
                 "TsinghuaNet8WebAPI.dll",
                 "TsinghuaNet8WebAPI.Bl.dll"
         };

         var cacheType = new List<Type>();
         List<Assembly> servicesAssembly = new List<Assembly>();
         foreach (var item in dllServiceFiles)
         {
             var dllFile = Path.Combine(basePath, item);
             if (!File.Exists(dllFile))
             {
                 throw new Exception($"{item}丢失，请重新编译后请检查 bin 文件夹，并拷贝。");
             }
             servicesAssembly.Add(Assembly.LoadFrom(dllFile));
         }

         //构造器注入
         builder.RegisterAssemblyTypes(servicesAssembly.ToArray()).
             Where(t => !t.IsAbstract) //还可以添加自定义的检索条件
             .InstancePerDependency(); //默认的类型

         #endregion
     }

 }

#region 注入接口服务
builder.Services.AddScoped<IGetEmrInfo, GetEmrInfo>();
#endregion

//第3步，配置日志信息，使用NLog
builder.Logging.ClearProviders();//清除所有的日志ILoggerProvider 记录提供器
builder.Logging.SetMinimumLevel(LogLevel.Information);
builder.Logging.AddNLog("Configs/NlogConfig.config");
builder.Host.UseNLog();//设置NLog 依赖注入 .net core 版本需要引用NLog.Web.AspNetCore
builder.Logging.AddConsole();
