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.
结合泛型接口类型和配置文件,得到IUnityContainer实例存于键值对中.
1 namespace Containers 2 { 3 public sealed class ObjectContainer 4 { 5 //fields 6 private static readonly object containerLock = new object(); 7 private static Dictionary<string,IUnityContainer> containers= 8 new Dictionary<string, IUnityContainer>(); 9 //*methods10 public static IObject CreateObject<IObject>(){ 11 IUnityContainer container = null;12 lock (containerLock) {13 Type type = typeof(IObject);14 string name = type.Assembly.GetName().Name;15 string configName = (Path.GetDirectoryName(type.Assembly.CodeBase)+16 @"\"+name+".container").Substring(6);17 if(containers.ContainsKey(name)){ 18 container = containers[name];19 }else{20 container = LoadContainer(configName);21 if(container != null){22 containers.Add(name ,container);23 }24 }25 }26 if(container != null){27 return container.Resolve<IObject>(new ResolverOverride[0]);28 }29 return default(IObject);30 }31 32 public static object CreateObject(Type interfaceType)33 {34 IUnityContainer container = null;35 lock (containerLock) {36 string name = interfaceType.Assembly.GetName ().Name;37 string configName = (Path.GetDirectoryName(interfaceType.Assembly.CodeBase)+38 @"\"+name+".container").Substring(6);39 if (containers.ContainsKey (name)) {40 container = containers [name]; 41 } else {42 container = LoadContainer (configName);43 if (container != null) {44 containers.Add (name , container);45 }46 }47 }48 if (container != null) {49 return container.Resolve (interfaceType, new ResolverOverride[0]);50 }51 return null;52 }53 54 //build with config55 public static IUnityContainer LoadContainer(string containerName)56 {57 IUnityContainer container = new UnityContainer ();58 ConfigurationFileMap map = new ConfigurationFileMap (){ 59 MachineConfigFilename = containerName60 }; 61 UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager62 .OpenMappedMachineConfiguration (map).GetSection ("unity");63 if (section != null) {64 container.LoadConfiguration (section);65 return container;66 }67 return null;68 }69 } 70 }
测试一下:
类
1 namespace TestClass 2 { 3 public class MyClass : EmptyInterface 4 { 5 public string sayHello() 6 { 7 return "Hello everyOne"; 8 } 9 }10 }
接口
1 namespace TestInterface2 {3 public interface EmptyInterface4 {5 string sayHello();6 }7 }
配置文件:
1 <?xml version="1.0" encoding="utf-8" ?> 2 <configuration> 3 <configSections> 4 <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection,Microsoft.Practices.Unity.Configuration"/> 5 </configSections> 6 <unity> 7 <typeAliases> 8 <typeAlias alias="singleton" 9 type="Microsoft.Practices.Unity.ContainerControlledLifetimeManager, Microsoft.Practices.Unity" />10 <typeAlias alias="external"11 type="Microsoft.Practices.Unity.ExternallyControlledLifetimeManager, Microsoft.Practices.Unity" />12 <typeAlias alias="perThread"13 type="Microsoft.Practices.Unity.PerThreadLifetimeManager, Microsoft.Practices.Unity" /> 14 15 16 <typeAlias alias="MyClass" type="TestClass.MyClass, TestClass" />17 <typeAlias alias="EmptyInterface" type="TestInterface.EmptyInterface, TestInterface" />18 </typeAliases>19 <containers>20 <container>21 <types>22 <type type="EmptyInterface" mapTo="MyClass" />23 <type type="TestInterface.EmptyInterface, TestInterface" mapTo="TestClass.MyClass, TestClass" name="test">24 <lifetime type="singleton" />25 </type>26 </types>27 </container>28 </containers>29 </unity>30 </configuration>
GO:
1 namespace Test 2 { 3 class MainClass 4 { 5 public static void Main (string[] args) 6 { 7 EmptyInterface iiterface = ObjectContainer.CreateObject<EmptyInterface> (); 8 Console.WriteLine (iiterface.sayHello ()); 9 }10 }11 }
