Mini容器支持6中生命周期类型:
1. Singleton :单利类型(缺省组件都是单利类型的生命周期,由容器进行托管的)
[Test] public void SingletonLifestyleTest() { ServiceRegistry.Register<Person>(); var person = ServiceLocator.Get<IPerson>(); Assert.IsTrue(person != null); var person2 = ServiceLocator.Get<IPerson>(); Assert.IsTrue(person2 != null); Assert.AreSame(person, person2); Assert.IsTrue(Person.HasVisited); }
2. Transient:临时,每次请求组件实例都返回一个新的实例,该实例不会被容器托管
[Test] public void TransientLifestyleTest() { ServiceRegistry.Current.Register<IPerson, Person>("person", LifestyleFlags.Transient); var person = ServiceLocator.Get<IPerson>(); Assert.IsTrue(person != null); var person2 = ServiceLocator.Get<IPerson>(); Assert.IsTrue(person2 != null); Assert.AreNotSame(person, person2); Assert.IsTrue(Person.HasVisited); }
[Test] public void ThreadLifestyleTest() { ServiceRegistry.Current.Register<IPerson, Person>("person", LifestyleFlags.Thread); IPerson person = null, person2 = null, person3 = null, person4 = null; PopulatePerThreadLifestyle(ref person, ref person2); var mre = new ResetEvent(false); ThreadPool.QueueUserWorkItem((s) => { PopulatePerThreadLifestyle(ref person3, ref person4); mre.Set(); }); mre.Wait(); Assert.AreSame(person, person2); Assert.AreSame(person3, person4); Assert.AreNotSame(person, person3); } private void PopulatePerThreadLifestyle(ref IPerson person, ref IPerson person2) { person = ServiceLocator.Get(typeof(IPerson)) as IPerson; Assert.IsTrue(person != null); person2 = ServiceLocator.Get(typeof(IPerson)) as Person; Assert.IsTrue(person2 != null); }
下面三种类型是在上面的三种类型之上扩展来的
4. GenericSingleton:
[Test] public void GenericSingletonLifestyleTest() { ServiceRegistry.Current.Register(typeof(IList<>), typeof(List<>)); var instance = ServiceLocator.Get<IList<int>>(); Assert.IsNotNull(instance); var instance2 = ServiceLocator.Get<IList<int>>(); Assert.IsNotNull(instance2); Assert.AreSame(instance, instance2); }
[Test] public void GenericTransientLifestyleTest() { ServiceRegistry.Current.Register(new ComponentInfo(null,typeof(IList<>),typeof(List<>), LifestyleFlags.Transient)); var instance = ServiceLocator.Get<IList<int>>(); Assert.IsNotNull(instance); var instance2 = ServiceLocator.Get<IList<int>>(); Assert.IsNotNull(instance2); Assert.AreNotSame(instance, instance2); }
[Test] public void GenericThreadLifestyleTest() { ServiceRegistry.Current.Register(new ComponentInfo(null, typeof(IList<>), typeof(List<>), LifestyleFlags.Thread)); IList<int> coll = null, coll2 = null, coll3 = null, coll4 = null; PopulatePerThreadLifestyle(ref coll, ref coll2); var mre = new ResetEvent(false); ThreadPool.QueueUserWorkItem((s) => { PopulatePerThreadLifestyle(ref coll3, ref coll4); mre.Set(); }); mre.Wait(); Assert.AreSame(coll, coll2); Assert.AreSame(coll3, coll4); Assert.AreNotSame(coll, coll3); } private void PopulatePerThreadLifestyle(ref IList<int> first, ref IList<int> second) { first = ServiceLocator.Get(typeof(IList<int>)) as IList<int>; Assert.IsTrue(first != null); second = ServiceLocator.Get(typeof(IList<int>)) as IList<int>; Assert.IsTrue(second != null); }
