Spring MVC Framework. The Spring Web MVC framework provides Model View Controller MVC architecture and ready components that can be used to develop flexible and loosely coupled web applications. The MVC pattern results in separating the different aspects of the application input logic, business logic, and UI logic, while providing a loose coupling between these elements. The Model encapsulates the application data and in general they will consist of POJO.

A Spring tutorial that shows you examples of how to implement CSV file download functionality in a Spring MVC application. The CSV library to be used is Super CSV. The View is responsible for rendering the model data and in general it generates HTML output that the clients browser can interpret. The Controller is responsible for processing user requests and building an appropriate model and passes it to the view for rendering. The Dispatcher. Servlet. The Spring Web model view controller MVC framework is designed around a Dispatcher. Servlet that handles all the HTTP requests and responses. The request processing workflow of the Spring Web MVC Dispatcher. Servlet is illustrated in the following diagram Following is the sequence of events corresponding to an incoming HTTP request to Dispatcher.

Spring Mvc Tutorial 3 0 Pdf File' title='Spring Mvc Tutorial 3 0 Pdf File' />Servlet After receiving an HTTP request, Dispatcher. Servlet consults the Handler. Mapping to call the appropriate Controller. The Controller takes the request and calls the appropriate service methods based on used GET or POST method. The service method will set model data based on defined business logic and returns view name to the Dispatcher. Servlet. The Dispatcher. Servlet will take help from View. Resolver to pickup the defined view for the request. Once view is finalized, The Dispatcher. Servlet passes the model data to the view which is finally rendered on the browser. All the above mentioned components, i. Handler. Mapping, Controller, and View. Resolver are parts of Web. Application. Context w which is an extension of the plain. Application. Context with some extra features necessary for web applications. Required Configuration. You need to map requests that you want the Dispatcher. Servlet to handle, by using a URL mapping in the web. The following is an example to show declaration and mapping for Hello. Web. Dispatcher. Servlet example. Web. AppID version 2. XMLSchema instance. Location http java. Spring MVC Applicationlt display name. Hello. Weblt servlet name. Dispatcher. Servlet. Hello. Weblt servlet name. The web. xml file will be kept in the Web. Yahoo Messenger Status History Cleaner For Windows. ContentWEB INF directory of your web application. Upon initialization of Hello. Web Dispatcher. Servlet, the framework will try to load the application context from a file named servlet name servlet. Web. ContentWEB INFdirectory. In this case, our file will be Hello. Webservlet. xml. Next, lt servlet mapping tag indicates what URLs will be handled by which Dispatcher. Servlet. Here all the HTTP requests ending with. Hello. Web Dispatcher. Servlet. If you do not want to go with default filename as servlet name servlet. Web. ContentWEB INF, you can customize this file name and location by adding the servlet listener Context. Loader. Listener in your web. Dispatcher. Servlet definition goes here. Config. Locationlt param name. WEB INFHello. Web servlet. Context. Loader. Listener. Now, let us check the required configuration for Hello. Web servlet. xml file, placed in your web applications Web. ContentWEB INF directory. XMLSchema instance. Location http www. Internal. Resource. View. Resolver. WEB INFjsp. Following are the important points about Hello. Web servlet. xml file The servlet name servlet. The lt context component scan. Spring MVC annotation scanning capability which allows to make use of annotations like Controller and Request. Mapping etc. The Internal. Resource. View. Resolver will have rules defined to resolve the view names. As per the above defined rule, a logical view named hello is delegated to a view implementation located at WEB INFjsphello. The following section will show you how to create your actual components, i. Controller, Model, and View. Defining a Controller. The Dispatcher. Servlet delegates the request to the controllers to execute the functionality specific to it. The Controllerannotation indicates that a particular class serves the role of a controller. The Request. Mapping annotation is used to map a URL to either an entire class or a particular handler method. Request. Mappinghello. Hello. Controller. Request. Mappingmethod Request. Method. GET. public String print. HelloModel. Map model. Attributemessage, Hello Spring MVC Framework. The Controller annotation defines the class as a Spring MVC controller. Here, the first usage of Request. Mapping indicates that all handling methods on this controller are relative to the hello path. Next annotationRequest. Mappingmethod Request. Method. GET is used to declare theprint. Hello method as the controllers default service method to handle HTTP GET request. You can define another method to handle any POST request at the same URL. You can write the above controller in another form where you can add additional attributes in Request. Mapping as follows. Hello. Controller. Request. Mappingvalue hello, method Request. Method. GET. public String print. HelloModel. Map model. Attributemessage, Hello Spring MVC Framework. The value attribute indicates the URL to which the handler method is mapped and the method attribute defines the service method to handle HTTP GET request. The following important points are to be noted about the controller defined above You will define required business logic inside a service method. You can call another method inside this method as per requirement. Based on the business logic defined, you will create a model within this method. You can use setter different model attributes and these attributes will be accessed by the view to present the final result. This example creates a model with its attribute message. A defined service method can return a String, which contains the name of the view to be used to render the model. This example returns hello as logical view name. Creating JSP Views. Spring MVC supports many types of views for different presentation technologies. These include JSPs, HTML, PDF, Excel worksheets, XML, Velocity templates, XSLT, JSON, Atom and RSS feeds, Jasper. Reports, etc. But most commonly we use JSP templates written with JSTL. Let us write a simple hello view in WEB INFhellohello. Hello Spring MVClt title. Here message is the attribute which we have set up inside the Controller. You can have multiple attributes to be displayed inside your view. Spring Web MVC Framework Examples. Based on the above concepts, let us check few important examples which will help you in building your Spring Web Applications.
