Spring MVC DispatcherServlet as Front Controller When the project is build by Eclipse, you will notice all the jars showing up in maven dependencies section. Notice the finalName configuration in build, so that our WAR file name doesn’t have version details. Our final pom.xml file will be like below. We need to add spring-web and spring-webmvc dependencies in pom.xml, also add servlet-api, jsp-api and jstl dependencies.
Now we can start making changes to it and create our spring mvc hello world example application. Our maven web application project skeleton code is ready. Next provide the pom.xml configurations as shown below. Right click on the project and select “Configure -> Convert to Maven Project”. So let’s convert our web project to maven. We want to use maven for easily manage our spring mvc dependencies. Converting Dynamic Web Project to Maven Project Click on Finish and you will have a new Dynamic Web Project in your eclipse project explorer. Next is the web module page, provide the context root of application as “spring-mvc-example” and make sure to check “Generate web.xml deployment descriptor” option. You might have to remove “src” folder from the list before adding this. On next page, provide the source folder as “src/main/java”. Provide name as “spring-mvc-example” in the next popup page, rest of the things should not required to be changed. Right click on the project explorer window and click on “New -> Dynamic Web Project” as shown in below image. Below images show how to do this and get our project skeleton structure ready. Since it’s a web application and we want to use maven for dependencies management, first of all we have to create a dynamic web application and then convert it to a maven project. Let’s get started and create our project right from the scratch. Spring MVC Example Hello World Eclipse Projectīelow image shows our Spring MVC example project in Eclipse. User.java will be the only model class we will have in our spring mvc example web application. home.jsp, user.jsp are the view pages in our spring mvc hello world example application. HomeController.java will be the single controller class in our spring mvc example application. It’s job is to pass request to appropriate controller class and send the response back when view pages have rendered the response page. DispatcherServlet is the front controller class to take all requests and start processing them. Below image shows Spring MVC architecture at a high level. Spring MVC is based on Model-View-Controller architecture. But today, I will be creating a basic hello world spring MVC application using maven and Eclipse. Sometime back in Spring MVC Tutorial, I explained how to create Spring MVC application using Spring Tool Suite.
