Spring MVC Learning Project

This tutorial will guide you through integrating Jetty with Eclipse and running a web application on the Jetty server inside Eclipse.

Steps:

1. Install Jetty Eclipse Plugin

When adding a server to the Servers view in Eclipse, you won't find an option for Jetty like you would for Tomcat, JBoss, Apache, etc. You first need to install a plugin.

• Go to Eclipse -> Install new Software menu.
• Click on "Add" and type the following:
  • Name: Jetty
  • Location: http://run-jetty-run.googlecode.com/svn/trunk/updatesite
• Select the Jetty plugin to install.
• Click "Next" and follow the installation process.

2. Add Java EE Perspective (Optional)

If you're not already in the Java EE perspective, it's recommended to switch to it for easier access to Java EE-related tools and views.

• Go to Window -> Perspective -> Open Perspective -> Other...
• Select "Java EE" and click "OK".

3. Create a Web Application

After restarting Eclipse, navigate to Project Explorer view or the New menu and click on New -> Dynamic Web Project.

• Configure the project by providing a name for it and click on "Next".
• Click "Next" again.
• Configure the Web Module.
• Click "Finish".

4. Running the Web Application

• Select the application you want to run on Jetty.
• Click on the "Run" button -> "Run Configurations".
• Configure your app on Jetty and click on "Run".
• Wait for the server to start. You should see logs indicating that the server has started.
• Open a browser and test the application.

Spring MVC:

• 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. Spring supports various technologies like freemarker, velocity, and thymeleaf.
• Controller: It contains the logical part of the application. @Controller annotation is used to mark that class as controller.
• Front Controller: It remains responsible for managing the flow of the web application. DispatcherServlet acts as a front controller in Spring MVC.

Spring Concepts in the Project:

• XML-based configuration of Spring MVC components
• XML auto scanning
• Configuration of InternalResourceViewResolver to resolve view names to JSP files
• Configuration of the DispatcherServlet in the web.xml
• The servlet name and the spring configuration file name should match, and it should follow YourServletName-servlet.xml, Here we have spring and spring-servlet.xml

Happy Coding!
