Ant - Spring MVC et fichier WAR Exemple

Ant - Exemple de fichier Spring MVC et WAR

Dans ce didacticiel, nous vous montrerons comment utiliser le script de génération Ant pour gérer un projet d'application Web Spring MVC, créer un fichier WAR et déployer sur Tomcat.

Technologies utilisées:

Eclipse 4.2
JDK 1.7
Ant 1.9.4
Ant-Ivy 2.4
logback 1.1.2
jstl 1.2
Spring 4.1.3.RELEASE
Tomcat 7

1. Répertoire des projets

Passez en revue la structure finale du projet:

Ant-SpringMVC-Project

ressources - Placez les fichiers xml et de propriétés requis par le code source Java. Comme log4j.properties, logback.xml, db.properties et etc.
src - Place le code source Java.
target - Le fichier WAR final sera stocké ici.
war - Pour les choses liées au Web.
war/WEB-INF – A standard WEB-INF directory structure for WAR file.
war/resources – For css and js files

2. Dépendances du projet

Nous utilisons Ivy pour télécharger les dépendances du projet:

ivy.xml

3. Ant Build Script

Script Ant pour gérer ce projet Spring MVC, lire recommande pour s'expliquer.

build.xml


    
        Create a Spring MVC (WAR) with Ant build script

4. Fichiers Spring MVC, JSP et XML

Voici les fichiers Java, XML et JSP complets, au cas où vous seriez intéressé.

4.1 Spring MVC controller class.

WelcomeController.java

package com.example.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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;

@Controller
public class WelcomeController {

    private static final String VIEW_INDEX = "index";
    private final static Logger logger = LoggerFactory.getLogger(WelcomeController.class);

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String welcome(ModelMap model) {

        model.addAttribute("message", "");
        logger.debug("[welcome]");

        return VIEW_INDEX;

    }

    @RequestMapping(value = "/{name}", method = RequestMethod.GET)
    public String welcomeName(@PathVariable String name, ModelMap model) {

        model.addAttribute("message", "Welcome " + name);
        logger.debug("[welcomeName] name : {}", name);
        return VIEW_INDEX;

    }

}

4.2 Simple logback configuration file, for logging.

logback.xml



    
      

        
            ANT + LogBack : %-5level %logger{36} - %msg%n

4.3 JSP and CSS file.

war/WEB-INF/pages/index.jsp

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>







Ant + Spring MVC Web Project Example

Message : ${message}

war/resources/theme1/css/core.css

h1 {
    font-size: 50px;
}

p {
    font-size: 20px;
    border: 5px solid red;
    padding:10px;
}

4.4 Spring Configuration.

mvc-dispatcher-servlet.xml



    

    
        
            /WEB-INF/pages/
        
        
            .jsp

4.5 A standard web.xml, integrate with Spring container.

web.xml



    Ant + Spring MVC Web Application

    
        mvc-dispatcher
        org.springframework.web.servlet.DispatcherServlet
        1
    

    
        mvc-dispatcher
        /
    

    
        contextConfigLocation
        /WEB-INF/mvc-dispatcher-servlet.xml
    

    
        org.springframework.web.context.ContextLoaderListener

5. Exécuter et tester

5.1 Default, it will run the package task.

$ pwd

$ ant

clean:
   [delete] Deleting directory /Users/example/Documents/workspace/AntSpringMVC/war/WEB-INF/classes
   [delete] Deleting directory /Users/example/Documents/workspace/AntSpringMVC/target

init:
    [mkdir] Created dir: /Users/example/Documents/workspace/AntSpringMVC/target
    [mkdir] Created dir: /Users/example/Documents/workspace/AntSpringMVC/war/WEB-INF/classes

Le résultat ci-dessus peut varier en fonction de votre environnement de développement. Si la construction réussit, le fichier WAR final sera créé dans le dossiertarget.

5.2 Review the content of the generated WAR file – helloproject.war
