Microsoft.Practices.Unity 通用类

类库的用法网上有很多,就不多说了,下面稍微封装了一下,记个笔记.

//2015-11-03 环境 .net 4.5 unity 3.x

结合泛型接口类型和配置文件,得到IUnityContainer实例存于键值对中.

namespace Containers
{
    public sealed class ObjectContainer
    {
        //fields
        private static readonly object containerLock = new object();
        private static Dictionary<string,IUnityContainer> containers=
            new Dictionary<string, IUnityContainer>();
        //*methods
        public static IObject CreateObject<IObject>(){ 
            IUnityContainer container = null;
            lock (containerLock) {
                Type type = typeof(IObject);
                string name = type.Assembly.GetName().Name;
                string configName = (Path.GetDirectoryName(type.Assembly.CodeBase)+
                    @""+name+".container").Substring(6);
                if(containers.ContainsKey(name)){ 
                    container = containers[name];
                }else{
                    container = LoadContainer(configName);
                    if(container != null){
                        containers.Add(name ,container);
                    }
                }
            }
            if(container != null){
                return container.Resolve<IObject>(new ResolverOverride[0]);
            }
            return default(IObject);
        }

        public static object CreateObject(Type interfaceType)
        {
            IUnityContainer container = null;
            lock (containerLock) {
                string name = interfaceType.Assembly.GetName ().Name;
                string configName = (Path.GetDirectoryName(interfaceType.Assembly.CodeBase)+
                    @""+name+".container").Substring(6);
                if (containers.ContainsKey (name)) {
                    container = containers [name]; 
                } else {
                    container = LoadContainer (configName);
                    if (container != null) {
                        containers.Add (name , container);
                    }
                }
            }
            if (container != null) {
                return container.Resolve (interfaceType, new ResolverOverride[0]);
            }
            return null;
        }

        //build with config
        public static IUnityContainer LoadContainer(string containerName)
        {
            IUnityContainer container = new UnityContainer ();
            ConfigurationFileMap map = new ConfigurationFileMap (){ 
                MachineConfigFilename = containerName
            }; 
            UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager
                .OpenMappedMachineConfiguration (map).GetSection ("unity");
            if (section != null) {
                container.LoadConfiguration (section);
                return container;
            }
            return null;
        }
    } 
}

测试一下:

类

namespace TestClass
{
    public class MyClass : EmptyInterface
    {
        public string sayHello()
        {
            return "Hello everyOne";
        }
    }
}

接口

namespace TestInterface
{
    public interface EmptyInterface
    {
        string sayHello();
    }
}

2015-11-03:修正 不同版本的unity写法有差异

配置文件:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection,Microsoft.Practices.Unity.Configuration"/>
  </configSections>
  <unity>
    <sectionExtension type="Microsoft.Practices.Unity.InterceptionExtension.Configuration.InterceptionConfigurationExtension,
      Microsoft.Practices.Unity.Interception.Configuration" />

    <alias alias="MyClass" type="TestClass.MyClass, TestClass"/>
    <alias alias="EmptyInterface" type="TestInterface.EmptyInterface, TestInterface"/>
    <alias alias="CallHandleInterceptionBehavior" type="TestClass.common.CallHandle,TestClass"/>

    <container>
      <extension type="Interception"/>
      <register type="EmptyInterface" mapTo="MyClass">
        <interceptor type="InterfaceInterceptor"/>
        <interceptionBehavior type="CallHandleInterceptionBehavior" />
      </register>
    </container>

  </unity>
</configuration>

GO:

namespace Test
{
    class MainClass
    {
        public static void Main (string[] args)
        {
            EmptyInterface iiterface = ObjectContainer.CreateObject<EmptyInterface> (); 
            Console.WriteLine (iiterface.sayHello ());
        }
    }
}
