This article mainly explains "the principle and function of ConfigurableApplicationContext interface in Spring". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn the principle and function of ConfigurableApplicationContext interface in Spring.

UML diagram

The role of interface

From the UML diagram above, you can see that ConfigurableApplicationContext directly inherits ApplicationContext, Lifecycle, and Closeable interfaces, so ApplicationContext is a subclass of ApplicationContext. Anyone who has used Spring or read the Spring source code must know the interface ApplicationContext. It functions like a name, which is the application context (indicating how important it is to have a good name), and contains information such as the unique ID of the program context, the application name and so on.

The Lifecycle interface is responsible for managing the life cycle of context, providing start () and stop () and isRunning () methods.

The Closeable interface is an interface provided by JDK to shut down components and release resources.

So the function of the ConfigurableApplicationContext API is to set the context ID, set the parent application context, add listeners, refresh the container, close, determine whether it is active, and so on. In fact, if you take a brief look at the ApplicationContext interface, you will find that the get method is followed by the set method, so the subinterface provides the set method.

At this point, I believe you have a deeper understanding of "the principle and function of ConfigurableApplicationContext interface in Spring". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
