Why spring mvc

While Spring MVC is an essential framework that exists within Spring as a whole, Spring Boot is an optional module that is used to streamline the development process, which can include integrating Spring MVC during the build process. Without Spring Boot, Spring MVC takes more time to use and requires manual configuration and separate deployment descriptors. Spring MVC uses three components to layout and design web applications, as its name implies: model, view, and controller.

The model component includes the data and structure of the application and plays a role in setting the rules and logic the application uses. The controller then translates and validates the input and passes it to the model or view for rendering.

Spring MVC also uses a Front Controller as a single point of entry for a client request and forwards the request to other controllers in the application for actual processing. To use Spring Boot, a good place to start is the Spring Initializer , which allows you to quickly pull up any dependencies and to fill in the project metadata.

This folder is then loaded to your IDE with specific code added. Read this guide for a step-by-step explanation. Spring Boot auto-configures the dependencies added onto the Initializer without the need to enter code for each individual dependency. The incoming request is first received by the DispatcherServlet.

The Controller calls the appropriate service methods and returns an object of ModelAndView containing the model data and view name. The DispatcherServlet now passes the model object to the View. The View then returns the result to the user. Light weight: Spring MVC uses light weight servlet container. Rapid Development: It provides a fast and parallel development.

Reusable Business code: Existing codes can be reused in the application. Flexible Mapping: It contains some specific annotations for flexible mapping. Powerful Configuration: It gives configuration for the framework as well as application classes. Create a controller class. The entry of the controller should be provided in the web.

For web applications Spring provides Spring MVC framework which is a widely used module of spring which is used to create scalable web applications.

Spring MVC framework enables the separation of modules namely Model View, Controller, and seamlessly handles the application integration. This enables the developer to create complex applications also using plain java classes.

The model object can be passed between view and controller using maps. The Spring MVC framework consists of the following components : Model — A model can be an object or collection of objects which basically contains the data of the application. View — A view is used for displaying the information to the user in a specific format.
