What is Struts MVC framework

Struts 2

Struts is an open source framework in java that extends the java servlet API. Struts architecture is based on MVC pattern it means Model, View and Controller.

Model: Model represent to the business component to the application means store and retrieving data from the backed database transfer to the presentation layer via controller.

View: View is a presentation layer it is present to the handling the request and response from the client and interact with the business component for Insert/update/retrieve data from its status and show to the client as response.

Controller: - The controller module acts as an interface between view and model. It intercepts all the requests i.e. receives input and commands to Model / View to change accordingly

Main Controller Class: Action Servlet is main controller class which handle all request are coming from client and decide to call which action is to need call to getting response from the server side.

Work flow of Struts MVC

Advantage of MVC Architecture

• Navigation control is centralized Now only controller contains the logic to determine the next page.
• Easy to maintain
• Easy to extend
• Easy to test
• Better separation of concerns

Disadvantage of MVC Architecture

• We need to write the controller code self. If we change the controller code, we need to recompile the class and redeploy the application.
