AutoFac中的生命周期概念非常重要,AutoFac也提供了强大的生命周期管理的能力。
AutoFac定义了三种生命周期:
Per Dependency
Single Instance
Per Lifetime Scope
Per Dependency为默认的生命周期,也被称为’transient’或’factory’,其实就是每次请求都创建一个新的对象
[Fact] public void per_dependency() { var builder = new ContainerBuilder(); builder.RegisterType<MyClass>().InstancePerDependency(); IContainer container = builder.Build(); var myClass1 = container.Resolve<MyClass>(); var myClass2 = container.Resolve<MyClass>(); Assert.NotEqual(myClass1,myClass2); }
Single Instance也很好理解,就是每次都用同一个对象
[Fact] public void single_instance() { var builder = new ContainerBuilder(); builder.RegisterType<MyClass>().SingleInstance(); IContainer container = builder.Build(); var myClass1 = container.Resolve<MyClass>(); var myClass2 = container.Resolve<MyClass>(); Assert.Equal(myClass1,myClass2); }
Per Lifetime Scope,同一个Lifetime生成的对象是同一个实例
[Fact] public void per_lifetime_scope() { var builder = new ContainerBuilder(); builder.RegisterType<MyClass>().InstancePerLifetimeScope(); IContainer container = builder.Build(); var myClass1 = container.Resolve<MyClass>(); var myClass2 = container.Resolve<MyClass>(); ILifetimeScope inner = container.BeginLifetimeScope(); var myClass3 = inner.Resolve<MyClass>(); var myClass4 = inner.Resolve<MyClass>(); Assert.Equal(myClass1,myClass2); Assert.NotEqual(myClass2,myClass3); Assert.Equal(myClass3,myClass4); }
[Fact] public void life_time_and_dispose() { var builder = new ContainerBuilder(); builder.RegisterType<Disposable>(); using (IContainer container = builder.Build()) { var outInstance = container.Resolve<Disposable>(new NamedParameter("name", "out")); using(var inner = container.BeginLifetimeScope()) { var inInstance = container.Resolve<Disposable>(new NamedParameter("name", "in")); }//inInstance dispose here }//out dispose here }
