Unity提供了根据名称空间进行匹配规则的类型NamespaceMatchingRule,它的通配符规则和MemberNameMatchingRule相同。看一个简单的示例:
1 public class MyObject 2 { 3 public virtual void DoWork() 4 { 5 6 } 7 8 public virtual void DoWork2() 9 { 10 11 } 12 13 public virtual void DoWork3() 14 { 15 16 } 17 } 18 19 IUnityContainer unityContainer = new UnityContainer(); 20 21 unityContainer.LoadConfiguration(); 22 unityContainer.Configure<Interception>() 23 .AddPolicy(“NamespaceMatchingRule”) 24 .AddMatchingRule(new NamespaceMatchingRule(“UnityTest6.*”, true)) 25 .AddCallHandler<Log4NetHandler>(); 26 unityContainer.RegisterType<MyObject>( 27 new Interceptor<VirtualMethodInterceptor>(), 28 new InterceptionBehavior<PolicyInjectionBehavior>() 29 ); 30 31 MyObject myObject = unityContainer.Resolve<MyObject>(); 32 33 myObject.DoWork(); 34 myObject.DoWork2(); 35 myObject.DoWork3();
配置文件如下定义:
