angular 2 dependency injection

First, dependency injection is basically three ways:1, the first is the setter injection, it can be understood to assign a value to the property of the interface type in the customer class, call different service types according to the actual type of the property, which may use the policy mode;2, through the constructo

holds the object, and then gives it to the A object, as to how spring creates that object, and when to create the object's , a object does not need to care about these details (when you were born, how it was born I do not care, can help me to work on the line), a get spring to our object, two people together to complete the work to complete.So the control reversal IoC (inversion of control) is to say that the creation of the object is transferred, the initiative of the previously created object

Thank http://blog.xiaohansong.com/2015/10/21/IoC-and-DI/for the map 1. What is control. As shown in the following figure, we see the object in the software system high coupling phenomenon. The rotation of all gears is controlled by an object., such as Class B. 2. What is control reversal. is used to object to decouple。 Decoupling between objects that have dependencies with third-party implementations. This third party is the IOC container. Once

Call the BeginProcessRequest method in Mvchandler to continue processing the request, and obtain the Controller and action information from the information resolved in 1 in the method, The Controller object is then activated using 2 types of Icontrollerfactory objects, and the corresponding action is eventually executed.The first of these methodsFrom the above

) { _dal.Insert(commandText); }} Finally, to truly complete dependency injection, AtuoFac will be launched: var builder = new ContainerBuilder(); builder.RegisterType From the preceding examples, we can see that the use of AutoFac is a bit like that of Unity. The key thing is the Container class.2. Description of common AutoFac methods (1) builder

Angularjs All functional components are organized in the form of dependency injection, and all components must be decoupled by means of containers (injectors) to access each other;1. The injector stores all recipes (name + class constructors): When Angualrjs starts, the component (Provider) is first registered by name in the injector;2, the component requires a $
