Je suis fier d'annoncer la première version du projet lin-mon-webapp avec Spring 3 Hibernate Maven sur JBoss 6.Le code source est disponible sur Google project :
http://code.google.com/p/lin-mon-webapp/.
Pour construire te déployer le war, vous aurez besoin de :
-> Maven 2
-> Mysql et de créer la base intégration avec la table User :
create database integration;
GRANT ALL ON integration.* TO 'integration'@'localhost' IDENTIFIED BY 'integration';
flush privileges;
create table USER (
user_id int(11) primary key,
first_name varchar(30),
last_name varchar(30),
email varchar(30) );
insert into USER values (1, 'titi', 'toto', 'mail@gmail.com');
Puis vous pouvez consulter le nombre et la liste des utilisateurs : http://localhost:8080/monitor/users
Voici les fichiers principaux de l'application :

First the
web.xml in whicn we create the servlet monitor :
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name>Maven Spring MVC 3 with JBOSS 6 </display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:/spring.xml
</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<!-- Front servlet. -->
<servlet>
<servlet-name>monitor</servlet-name>
<display-name>monitor</display-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/monitor-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Every request on / will be treat by monitor servlet. -->
<servlet-mapping>
<servlet-name>monitor</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
Then there is the monitor servlet which define the controller, view relover ... and also where to search controller methos:
monitor-servlet.xml
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"
default-autowire="byName">
<!-- Every contoller is automaticaly detect due to annotation @Controller.
We define here in wich package the post processor have to search controller annotation -->
<context:component-scan base-package="fr.dr.monitor.controller"/>
<context:annotation-config/>
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"/>
</beans>
The controller class contains this method :
@RequestMapping(value = "users", method = RequestMethod.GET)
public ModelAndView getUsers() {
List<User> users = userDAO.getUsers();
ModelAndView modelAndView = new ModelAndView("users");
modelAndView.addObject("users", users);
return modelAndView;
}
To do that the controller call UserDAO methods and Hibernate will retreive data in User table.
Here is the spring beans file that create Hibernate Session and datasource :
spring.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"

xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
<!-- <context:component-scan base-package="com.springhibernate.integration.aspects" />-->
<!--Enables the use of @AspectJ style of aspects' declarations. AspectJ run-time isn't necessarily involved-->
<aop:aspectj-autoproxy/>
<!--Platform Transaction Manager declared as "transactionManager" will be used.-->
<!--"aspectj" mode enables load-time/compile-time weaving of transactional methods, which enables
those methods to be intercepted even when called internally.
(Unlike Spring generated proxies which will only be intercepted when called from outside)-->
<tx:annotation-driven transaction-manager="transactionManager"/>
<!--
Activates various annotations to be detected in bean classes: Spring's
@Required and @Autowired, as well as JSR 250's @PostConstruct,
@PreDestroy and @Resource (if available) and JPA's @PersistenceContext

-->
<context:annotation-config/>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="hibernateProperties">
<props>
<prop key="dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="show_sql">true</prop>
</props>
</property>
<property name="mappingResources">
<list>
<value>mappings/user.hbm.xml</value>
</list>

</bean>
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>

<property name="url" value="${database.url}"/>
<property name="username" value="${database.username}"/>
<property name="password" value="${database.password}"/>
</bean>
<!--repository init area-->
<bean id="repository.users" class="fr.dr.monitor.repository.UserDAO"
autowire="constructor"/>
</beans>
The session factory will be inject to UserDAO to query on USER table :
UserDAO.java
@Repository
@Transactional
public class UserDAO implements IUser {
private SessionFactory sessionFactory;
@Autowired
public UserDAO(SessionFactory sessionFact) {
this.sessionFactory = sessionFact;
}
@Transactional
public User getUser(Long id) {
return (User) sessionFactory.getCurrentSession().get(User.class, id);
}
@SuppressWarnings("unchecked")
@Transactional
public List<User> getUsers() {
return sessionFactory.getCurrentSession().createQuery("from User user").list();
}
@Transactional
public void addUser(User user) {
sessionFactory.getCurrentSession().save(user);
}
}
