![]() It has all the basic features of the core Spring framework like Dependency Injection and Inversion of Control. So, Spring MVC is an integrated version of the Spring framework and Model View Controller. The MVC term signifies that it follows the Model View Controller design pattern. Spring MVC is a Java framework used to build web-based applications. Spring MVC vs Spring Boot- Which is Better?.Difference Between Spring MVC and Spring Boot.It contains all the business logics and acts as a bridge between controller and DAO - It serves as a specialization of allowing for implementation classes to be autodetected through classpath scanning. tViewName( "userDetails") įollowing is the service class that acts as a helper class for controller to process the requests. ModelAndView.addObject( "users", userDetails) List userDetails = userService.getUserDetails() ModelAndView modelAndView = new ModelAndView() Import public class UserController private UserService = "/users", method = RequestMethod. It can be also used onto specific handler - It marks a constructor, field, setter method or config method as to be autowired by Spring's dependency injection facilities. Marking it with annotation also register this class as a spring - This annotation is for mapping web requests onto specific handler methods. It processes the requests and return model and view to the front - To mark this class as a controller, we have annotated this class with annotation. It handles the request that is mapped for /users. This class acts as a handler class in spring mvc.

Maven-war-plugin - This is required to build war package by maven as we are excluding web.xml based configurations. Jstl - Provides all the dependencies for jstl. rvlet-api - Provides all the dependency related to servlet api. Including this dependency automatically includes spring-web. Spring-webmvc - provides core HTTP integration including filters. The jsp pages are defined inside WEB-INF/jsp. Here we have defined our config classes inside the package and all the static components inside webapp/ui. Now let us develop a spring mvc annotation example based on the architecture defined above. Once this is identified the front controller renders that view to the client. The model object holds tha data and name of the view.Īgain, the front controller takes help from view resolver to identify the correct view. Then this controller processes this request and returns model object to the front controller. Once that is identified, the request is forwarded to that controller. The front controller(DispatcherServlet) intercepts all the incoming requests(normal servlet configuration) and it identifies the appropriate controller from the configurations we have defined to handle this request. It is defined at .DispatcherServlet in package.įollowing is a diagram that explains the architecture of spring mvc. controllers and render views to the client. It has a central servlet called as DispatcherServlet which is well known as front controller that intercepts all the requests, identify the appropriate handler i.e. Spring MVC(Model-View-Controller) provides a convenient way to develop a java based web application.
