    Autofac的高级使用——Autofac.2.6.3.862

     

    1. 使用代码方式进行组件注册【依赖服务类和组件类】

    [csharp] view plaincopyprint?
    1. /// <summary>  
    2.     /// 管理类  
    3.     /// </summary>  
    4.     public partial class Mgr  
    5.     {  
    6.         private static IContainer container = null;  
    7.   
    8.         /// <summary>  
    9.         /// 自定义容器和组件注册  
    10.         /// </summary>  
    11.         /// <returns></returns>  
    12.         public static IContainer GetContainer()  
    13.         {  
    14.   
    15.             if (container == null)  
    16.             {  
    17.                 var builder = new ContainerBuilder();  
    18.                 //builder.RegisterType<SqlDatabase>().As<IDatabase>();  
    19.                 builder.RegisterType<SqlDatabase>().Named<IDatabase>("AutofacDemo.Lib.Sql.SqlDatabase");  
    20.                 builder.RegisterType<OracleDatabase>().Named<IDatabase>("AutofacDemo.Lib.Oracle.OracleDatabase");  
    21.   
    22.                 container = builder.Build();  
    23.   
    24.             }  
    25.             return container;  
    26.         }  
    27.     }  
    /// <summary>
    /// 管理类
    /// </summary>
    public partial class Mgr
    {
        private static IContainer container = null;

        /// <summary>
        /// 自定义容器和组件注册
        /// </summary>
        /// <returns></returns>
        public static IContainer GetContainer()
        {

            if (container == null)
            {
                var builder = new ContainerBuilder();
                //builder.RegisterType<SqlDatabase>().As<IDatabase>();
                builder.RegisterType<SqlDatabase>().Named<IDatabase>("AutofacDemo.Lib.Sql.SqlDatabase");
                builder.RegisterType<OracleDatabase>().Named<IDatabase>("AutofacDemo.Lib.Oracle.OracleDatabase");

                container = builder.Build();

            }
            return container;
        }
    }


     

    2. 使用配置文件进行组件注册【不需要依赖】


    2.1. 定义配置文件

    [html] view plaincopyprint?
    1. <?xml version="1.0"?>  
    2. <configuration>  
    3.   <configSections>  
    4.     <section name="autofac" type="Autofac.Configuration.SectionHandler, Autofac.Configuration"/>  
    5.   </configSections>  
    6.   <autofac>  
    7.     <components>  
    8.       <component name="AutofacDemo.Lib.Oracle.OracleDatabase" type="AutofacDemo.Lib.Oracle.OracleDatabase, AutofacDemo.Lib.Oracle" service="AutofacDemo.Lib.IDatabase, AutofacDemo.Lib"/>  
    9.       <component name="AutofacDemo.Lib.Sql.SqlDatabase" type="AutofacDemo.Lib.Sql.SqlDatabase, AutofacDemo.Lib.Sql" service="AutofacDemo.Lib.IDatabase, AutofacDemo.Lib"/>  
    10.     </components>  
    11.   </autofac>  
    12. <startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup></configuration>  
    <?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="autofac" type="Autofac.Configuration.SectionHandler, Autofac.Configuration"/>
  </configSections>
  <autofac>
    <components>
      <component name="AutofacDemo.Lib.Oracle.OracleDatabase" type="AutofacDemo.Lib.Oracle.OracleDatabase, AutofacDemo.Lib.Oracle" service="AutofacDemo.Lib.IDatabase, AutofacDemo.Lib"/>
      <component name="AutofacDemo.Lib.Sql.SqlDatabase" type="AutofacDemo.Lib.Sql.SqlDatabase, AutofacDemo.Lib.Sql" service="AutofacDemo.Lib.IDatabase, AutofacDemo.Lib"/>
    </components>
  </autofac>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup></configuration>


    2.2. 读取config配置文件进行组件注册

    [csharp] view plaincopyprint?
    1. /// <summary>  
    2. /// 根据配置文件里的服务名生成对象  
    3. /// </summary>  
    4. public static void GetFrom_Config()  
    5. {  
    6.   
    7.   
    8.     var builder = new ContainerBuilder();  
    9.   
    10.     //从.config配置文件中取得相关的组件注册  
    11.     builder.RegisterModule(new ConfigurationSettingsReader("autofac"));   
    12.   
    13.      
    14.   
    15.     using (var container = builder.Build())  
    16.     {  
    17.         string vServiceName = "AutofacDemo.Lib.Oracle.OracleDatabase";//服务名  
    18.         //vServiceName = "AutofacDemo.Lib.Sql.SqlDatabase";  
    19.   
    20.         //是否存在服务名  
    21.         if (container != null)  
    22.         {  
    23.             if (container.IsRegisteredWithName(vServiceName, typeof(IDatabase)))  
    24.             {  
    25.                 IDatabase db = container.ResolveNamed<IDatabase>(vServiceName);  
    26.                 if (db != null)  
    27.                 {  
    28.                     db.Select("..........");  
    29.                 }  
    30.             }  
    31.         }  
    32.     }  
    33. }  
            /// <summary>
        /// 根据配置文件里的服务名生成对象
        /// </summary>
        public static void GetFrom_Config()
        {


            var builder = new ContainerBuilder();

            //从.config配置文件中取得相关的组件注册
            builder.RegisterModule(new ConfigurationSettingsReader("autofac")); 

           

            using (var container = builder.Build())
            {
                string vServiceName = "AutofacDemo.Lib.Oracle.OracleDatabase";//服务名
                //vServiceName = "AutofacDemo.Lib.Sql.SqlDatabase";

                //是否存在服务名
                if (container != null)
                {
                    if (container.IsRegisteredWithName(vServiceName, typeof(IDatabase)))
                    {
                        IDatabase db = container.ResolveNamed<IDatabase>(vServiceName);
                        if (db != null)
                        {
                            db.Select("..........");
                        }
                    }
                }
            }
        }


     

    2.3. 是否存在服务名，存在，则根据服务名取得对象

    [csharp] view plaincopyprint?
    1. //是否存在服务名  
    2. if (container.IsRegisteredWithName(vServiceName, typeof(IDatabase)))  
    3. {  
    4.     IDatabase db = container.ResolveNamed<IDatabase>(vServiceName);  
    5.     if (db != null)  
    6.     {  
    7.         db.Select("..........");  
    8.     }  
    9. }  
                    //是否存在服务名
                if (container.IsRegisteredWithName(vServiceName, typeof(IDatabase)))
                {
                    IDatabase db = container.ResolveNamed<IDatabase>(vServiceName);
                    if (db != null)
                    {
                        db.Select("..........");
                    }
                }

    4. 使用代码方式进行组件注册【不需要依赖】【类似反射的全字符串形式】

    [csharp] view plaincopyprint?
    1. /// <summary>  
    2.         /// 自定义容器和通过反射进行组件注册  
    3.         /// </summary>  
    4.         /// <returns></returns>  
    5.         public static IContainer GetContainer()  
    6.         {  
    7.   
    8.             if (container == null)  
    9.             {  
    10.                 var builder = new ContainerBuilder();  
    11.   
    12.   
    13.                 Type objType = Type.GetType("AutofacDemo.Lib.IDatabase, AutofacDemo.Lib");  
    14.                 Type objTypeA = Type.GetType("AutofacDemo.Lib.Oracle.OracleDatabase, AutofacDemo.Lib.Oracle");  
    15.                 Type objTypeB = Type.GetType("AutofacDemo.Lib.Sql.SqlDatabase, AutofacDemo.Lib.Sql");  
    16.   
    17.   
    18.                 builder.RegisterType(objTypeA).Named("AutofacDemo.Lib.Oracle.OracleDatabase", objType);  
    19.                 builder.RegisterType(objTypeB).Named("AutofacDemo.Lib.Sql.SqlDatabase", objType);  
    20.   
    21.   
    22.                 ////需要知道接口  
    23.                 //builder.RegisterType(objTypeA).Named<objType>("AutofacDemo.Lib.Sql.SqlDatabase");  
    24.                 //builder.RegisterType(objTypeB).Named<objType>("AutofacDemo.Lib.Oracle.OracleDatabase");  
    25.   
    26.                 container = builder.Build();  
    27.   
    28.             }  
    29.             return container;  
    30.         }  
    /// <summary>
        /// 自定义容器和通过反射进行组件注册
        /// </summary>
        /// <returns></returns>
        public static IContainer GetContainer()
        {

            if (container == null)
            {
                var builder = new ContainerBuilder();


                Type objType = Type.GetType("AutofacDemo.Lib.IDatabase, AutofacDemo.Lib");
                Type objTypeA = Type.GetType("AutofacDemo.Lib.Oracle.OracleDatabase, AutofacDemo.Lib.Oracle");
                Type objTypeB = Type.GetType("AutofacDemo.Lib.Sql.SqlDatabase, AutofacDemo.Lib.Sql");


                builder.RegisterType(objTypeA).Named("AutofacDemo.Lib.Oracle.OracleDatabase", objType);
                builder.RegisterType(objTypeB).Named("AutofacDemo.Lib.Sql.SqlDatabase", objType);


                ////需要知道接口
                //builder.RegisterType(objTypeA).Named<objType>("AutofacDemo.Lib.Sql.SqlDatabase");
                //builder.RegisterType(objTypeB).Named<objType>("AutofacDemo.Lib.Oracle.OracleDatabase");

                container = builder.Build();

            }
            return container;
        }
