how to create a application context file

Unless you are writing an application that needs an extremely small memory footprint, BeanFactory shouldn't be used directly. The ApplicationContext is a subclass of the BeanFactory interface so it has all the functionality a BeanFactory has and more. The lowest level implementation of the IoC container is the BeanFactory, but it is recommended to use an ApplicationContext for your application. If you're developing a web application, you may not need to directly access the IoC container at all since it will automatically handle instantiation of your controller and any beans it requires. There should only be a few key points where the application code needs to directly access the IoC container, and this is true even for legacy applications. By delegating as much bean creation as possible to Spring, Once the IoC container is initialized, you can retrieve your Spring beans. You can also use Spring's resource abstraction for loading other files required for your application. Spring's resource abstraction allows you to load configuration files from wherever you'd like - the classpath, the file system, FTP, and HTTP locations. n(SpringMain.class, void run(String.Spring can be used in standard applications, web applications, full Java EE applications, and other containers, the only requirement is that you run a standard JVM. Public class SpringMain implements CommandLineRunner ApplicationContext applicationContext

We can get the ApplicationContext, injecting it using ApplicationContext applicationContext Some more examples of ApplicationContext using Spring Boot.Get ApplicationContext Using the ApplicationContextAware interface.Get ApplicationContext using n() method.Get ApplicationContext using annotation.
