We will learn how to create a simple Web application with Spring framework with Eclipse. The Web application has two JSP pages:
- hello.jsp: It displays a welcome phrase to Spring framework!
Web application creation with Eclipse
- Step 1: start the Eclipse J2EE environment, click on New project -> Dynamic Web project
- Step 2: type the project name as spring-helloworld, then click Finish
- Step 3: create folders, files in project directory as follow:
- in the src folder, create a package control. In the package control, create a java class of name HelloControl.
- in the WebContent folder, create a JSP page: hello.jsp.
- in the WebContent/WEB-INF/ folder, create two files: web.xml and spring-helloworld-servlet.xml
- Step 4: Download all Spring library files (from: http://sourceforge.net/projects/springframework/) and then add them into the WebContent/WEB-INF/lib folder:
- Step 5: define all java classes, jsp files and .xml files
HelloControl.java
package control;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.ui.ModelMap;
@Controller
public class HelloControl{
@RequestMapping(value = "/hello", method = RequestMethod.GET)
public String printHello(ModelMap model) {
model.addAttribute("message", "Hello Spring MVC Web Framework!");
return "hello";
}
}
hello.jsp
