The technical principle analysis of the Silk DI framework in the Java library

The Silk DI framework is a dependent injection framework for the Java class library. It can help developers to achieve loose coupling components and improve the reuse and testability of the code.Let's analyze the technical principles of the Silk Di framework in the Java class library. The core principle of the Silk DI framework is to rely on injection. It realizes the association and decoupling between components by dynamically injecting objects in the application.In the Silk DI framework, developers can use annotations or configuration files to describe the dependent relationship between components and them, and the framework dynamically creates the dependencies between the management objects according to these descriptions. In the Silk DI framework, developers need to define one or more container (Container). The container is a container used to manage objects. It is responsible for creating a dependent relationship between objects and management objects.Developers can register various components in the container and describe the dependency relationship between them. The framework will create the association between the acting objects and maintain the association between them according to these descriptions. The following is a simple example code that demonstrates how to use annotations in the Silk Di framework to describe components and dependencies: // Define a service interface public interface UserService { void getUserInfo(); } // Define a service implementation class, and use the @SerVice annotation identification as the component @Service public class UserServiceImpl implements UserService { public void getUserInfo() { System.out.println("Getting user info..."); } } // Define a controller class, and use @inject annotations to inject inject use public class UserController { @Inject private UserService userService; public void getUser() { userService.getUserInfo(); } } In the above example, we define an UserService interface and an UserServiceImpl implementation class, and an UserController controller class.The @Service annotation logo is used as a component on the UserServiceImpl class, and the @Inject annotation is used on the UserService member variable in the UserController class to inject the UserService component. The above is the analysis of the technical principles of the Silk DI framework in the Java class library.
