Can MVC have multiple controllers?
In Spring MVC, we can create multiple controllers at a time. It is required to map each controller class with @Controller annotation. Create the controller class. Provide the entry of controller in the web.
Should each model have its own controller?
If you feel each model that you are talking above is a resource and the user can access it through a separate URL then you can go ahead and create a separate controller for each else the single AccountController is fine.
What is the purpose of separating model view and controller?
The controller knows how to link a specific view to your model. The separation of model and controller, apart from improving documentation and maintainability, has the immediate benefit of allowing multiple views to display the same information from the model without adding any complexity to either.
Can two controllers have same request mapping?
You cannot. A URL can only be mapped to a single controller. It has to be unique.
Can one controller have multiple views?
Yes You can use multiple View in one Controller.
What is a request mapping?
@RequestMapping is one of the most widely used Spring MVC annotation. RequestMapping annotation is used to map web requests onto specific handler classes and/or handler methods. @RequestMapping can be applied to the controller class as well as methods.
What is MVC mapping?
The model (the M in MVC) is a Map interface, which allows for the complete abstraction of the view technology. You can integrate directly with template based rendering technologies such as JSP, Velocity and Freemarker, or directly generate XML, JSON, Atom, and many other types of content.
How to separate views and controllers in MVC?
The simplest form of separation I use is to retain the Views “as is” in the original MVC project but remove the Controllers. Then in a new ClassLibrary project add the Controller classes and ensure they inherit from Controller.
Is it advisable to put controllers into a separate project?
This has the added benefit that you have a place to put your Controller logic that differs from project to project. Also, it is easier for other developers to quickly find your Controller logic because the Controllers exist in the standard place. Regarding whether this is advisable, I think it absolutely is.
What’s the difference between a view and a controller?
A view should contain only logic related to generating the user interface. A controller should only contain the bare minimum of logic required to return the right view or redirect the user to another action (flow control). Everything else should be contained in the model. In general, you should strive for fat models and skinny controllers.
Where are models, views, and controllers located?
In particular, you’ll see three folders named Models, Views, and Controllers. As you might guess from the folder names, these folders contain the files for implementing models, views, and controllers. If you expand the Controllers folder, you should see a file named AccountController.cs and a file named HomeController.cs.
