factory class. This not only increases the scalability of our system, but also improves the overall robustness of our system.Finally, to summarize what is control reversal, my answer has been given at the beginning of the article, the following is the answer to Wikipedia:　　　　Control inversion (inversion of controls, abbreviated to IOC) is a design principle in object-oriented programming that can be used to reduce the degree of coupling between computer code. The most common of these is called

Spring can effectively organize objects at various layers of J2EE applications. Whether it is the action object of the control layer, the service object of the business layer, or the DaO object of the persistence layer, it can be organically coordinated and run under the management of spring. Spring organizes objects at different layers in a loosely coupled manne

Autofac is a dependency injection (Di, dependency injection) Container applied to the. NET platform. It is close to and fits with the C # language. As application systems become increasingly large and complex, the use of autofac containers to manage the relationships between components can be "flat" and the complex class dependencies, with good adaptability and convenience.In this blog post, we will apply a

Control inversion/Dependency InjectionRecently, I bought this Spring starter book: Spring in Action. The view from the hotel was good. It's a bit of a starter. Manning's book is still good, although I do not like those who only see Manning book the same focus on Manning, but with reverence for the mood and passion browse through again. Once again, the core concep

most commonly used. Automatic injection of dependent objects is achieved by tagging @Inject annotations before the declaration of the field.Human { ... Human () {}} The above code looks amazing: Just add an annotation and the Father object will be automatically injected? How is this injection process done?Essentially, if you just write a @Inject note, Father is not automatically injected. You also need to use a dependency injection framework an

For generic Java projects, they are more or less a dependency type, which is made up of a number of mutually cooperative objects. Spring calls this collaborative relationship a dependency . If a component calls a method of component B, it can be called a component dependent on the B component, and dependency injection

again gave a new name: "Dependency Injection", In contrast to the IOC, "dependency Injection" clearly describes the "injected object relies on the IOC container configuration dependent object".Read many of the spring's IOC understanding of the article, a lot of people on the IOC and DI interpretation are obscure, anyway, is a kind of inexplicable, the sense of the unknown, after reading is still confused,
