Spring is a powerful Java application framework that is widely used in Java applications. Provides enterprise-class services for Plainoldjavaobjects (POJOs). Spring uses a dependency injection mechanism to simplify work while improving testability. Springbeans and dependencies, as well as the services required for the beans class, are described in detail in the configuration file, which is a typical XML format. But it is both lengthy and impractical. It's hard to read and manage for big projects

handlers are separated, and an event handler should get relevant information from the event object and pass that information to a method that handles the application. Benefits: You can more easily change the events that trigger a particular process, and second you can test the code without attaching to the event, making it easier to create unit tests or automated application processes. Several principles of loose coupling between application and business logic: Do not
