In the context of the Spring Web MVC framework, the "Model" refers to the component that encapsulates the application data and is responsible for managing the data, logic, and rules of the application. The Model is part of the Model-View-Controller (MVC) architecture that Spring MVC adheres to, which helps in separating the different aspects of the application, such as presentation, business logic, and data access, thus promoting organized and reusable code[1][2].
The Model in Spring MVC is typically implemented using simple Java objects known as Plain Old Java Objects (POJOs). These objects represent the data of the application and can be populated, manipulated, and passed between different components of the application, such as controllers and views[1][2][3].
In a typical Spring MVC application, the controller interacts with the Model by updating or retrieving data, which is then displayed to the user through the View. The Model is responsible for encapsulating the application's state and provides data to the View as well as responding to instructions from the Controller to change the state[1][2][3].
The Model is a key component in ensuring the separation of concerns within the MVC pattern, allowing for more modular, testable, and maintainable code. This separation allows developers to modify or test one aspect of the application (like UI logic or business logic) without impacting others[1][2][3].
