Now we can see a rapid guide to quickly see how to run a simple dynamic web project using project Spring MVC 3. The very essential to see how it works.
- open eclipse
- create a new dynamic web project(in my case I set 2.5 value into Dynamic web module version combo selection)
- this is the content of web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>Spring3 MVC Application</display-name>
<servlet>
<servlet-name>spring-web</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring-web</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
- always here, under WEB-INF, create a new spring-web-servlet.xml
(note that name first part"spring-web" have to be the same of what you declared as servlet-name in the web.xml mapping to the DispatcherServlet)
with this content:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd">
<context:component-scan base-package="com.web" />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<mvc:annotation-driven />
</beans>
- under src folder, create a new package named: com.web.controller
- and put into WebController.java:
package com.web.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class WebController {
@RequestMapping(value = "/", method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
model.addAttribute("message", "Spring 3 MVC Example");
return "home";
}
@RequestMapping(value = "/main/{name:.+}", method = RequestMethod.GET)
public ModelAndView hello(@PathVariable("name") String name) {
ModelAndView model = new ModelAndView();
model.setViewName("main");
model.addObject("msg", name);
return model;
}
}
- under WEB-INF/lib put into these libs(you need to search and download all of them):
aopalliance-1.0.jar
commons-logging-1.1.3.jar
jstl-1.2.jar
spring-aop-3.2.13.RELEASE.jar
spring-beans-3.2.13.RELEASE.jar
spring-context-3.2.13.RELEASE.jar
spring-core-3.2.13.RELEASE.jar
spring-expression-3.2.13.RELEASE.jar
spring-web-3.2.13.RELEASE.jar
spring-webmvc-3.2.13.RELEASE.jar
- create the folder path WEB-INF/views/jsp
- put into these two jsp: home.jsp(welcome page)
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html>
<html lang="en">
<head>
<title>Spring MVC 3 example</title>
</head>
<body>
<div>
<div>
<p>
<c:if test="${not empty name}">
Welcome to main menu ${name}
</c:if>
</p>
</div>
<a href="${pageContext.request.contextPath}/main/maurizio">go to main menu</a>
</div>
</body>
</html>
- and main.jsp(target page, only to see the navigation):
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html>
<html lang="en">
<head>
<title>Spring MVC 3 example</title>
</head>
<body>
<div>
<p>
<c:if test="${not empty name}">
Welcome! Please click above for the main menu... ${name}
</c:if>
</p>
</div>
</body>
</html>
So now you can try all:
- building a war file through right clicking on the project, then Export --> find and select War file, and moving the war file under an active application server.
- configuring an application server inbound to eclipse and adding the entire project to it.
Indipendently to the choosen way open a browser and point to:
http://localhost:8080/startingWithSpringMVC3
and test if all is ok....
You checkout the entire project(under sourceforge.net) from command line with this:
svn checkout svn://svn.code.sf.net/p/mauriziofranco/code/StartingWithSpringMVC3/trunk/startingWithSpringMVC3 mauriziofranco-code
That's all....
Bye...
