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.

 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         //*methods
10         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 config
55         public static IUnityContainer LoadContainer(string containerName)
56         {
57             IUnityContainer container = new UnityContainer ();
58             ConfigurationFileMap map = new ConfigurationFileMap (){ 
59                 MachineConfigFilename = containerName
60             }; 
61             UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager
62                 .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 TestInterface
2 {
3     public interface EmptyInterface
4     {
5         string sayHello();
6     }
7 }

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:

 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 }
