Creazione di una semplice web application utilizzando maven, jpa2, spring, struts2, mysql (parte 2)

una volta configurato correttamente il file POM.xml possiamo iniziare la configurazione di tutti gli altri file necessari per il buon funzionamento della nostra applicazione web

Configurazione web.xml

sotto la cartella WEB-INF inserire il seguente file web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app id="web-app" version="2.4" 
         xmlns="http://java.sun.com/xml/ns/j2ee"

Creazione di una semplice web application utilizzando maven, jpa2, spring, struts2, mysql

medium economic 1 day

In questo tutorial verrà spiegato come sviluppare una semplice web application utilizzando tecnologie come maven, jpa2, struts2, spring e mysql.

Ambiente di lavoro:

  • MySQL Server
  • Eclipse + da “Eclipse Market Place”  “Maven Integration for Eclipse”
  • JDK 1.7

Creazione tabella mysql:

Prima di iniziare tutto il lavoro creiamo una tabella che chiameremo user

CREATE  TABLE IF NOT EXISTS `user` (
  `id` BIGINT NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(255) NOT NULL ,
  `password` VARCHAR(255) ,
  PRIMARY KEY (`id`) )
ENGINE = InnoDB;
									

 

Creazione di un nuovo progetto Maven su Eclipse:

– creiamo un nuovo progetto “maven” su eclipse

– impostiamo  maven-archetypes-webapp

– impostiamo grupId e artifactId come in figura



Struttura progetto e configurazione pom.xml

Una volta generato il progetto maven, Eclipse ci propone tutto il progetto come in figura

 Il prossimo passo sarà quello di configurare il file pom.xml in modo da personalizzare il building e includere le tecnologie che ci interessano.

In particolare includiamo le dipendenze per: struts2, spring, mysql connector, servlet e jsp, hibernate, log4j e junit.

Dopo di che impostiamo anche il <build> in modo da utilizzare alcuni plugin tra cui il web server jetty.
