Hi
we have been starting with our hibernate/spring/wicket app a few weeks ago and
its quite easy. We do it with maven2 like this:
i show you some snippets, please ask me if you have any further questions:
in your pom.xml:
=========================
<properties>
<wicket.version>1.4.5</wicket.version>
</properties>
...
<dependency>
<groupId>org.apache.wicket</groupId>
<artifactId>wicket</artifactId>
<version>${wicket.version}</version>
</dependency>
<dependency>
<groupId>org.apache.wicket</groupId>
<artifactId>wicket-extensions</artifactId>
<version>${wicket.version}</version>
</dependency>
<dependency>
<groupId>org.apache.wicket</groupId>
<artifactId>wicket-spring</artifactId>
<version>${wicket.version}</version>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
</exclusion>
</exclusions>
</dependency>
web.xml
=========================
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";
version="2.4">
<display-name>wicket</display-name>
<filter>
<filter-name>wicket.wicket</filter-name>
<filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
<init-param>
<param-name>applicationClassName</param-name>
<param-value>org.yourapp.MyApplication</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>wicket.wicket</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
you can start the spring context directly in your web.xml, but I wanted to
start my SpringApplication manually in my Application class:
in your MyApplication.java
=========================
public class MyApplication extends WebApplication
@Override
protected void init ( )
{
WebApplicationContext ctx = start_your_spring_context_here
addComponentInstantiationListener(new SpringComponentInjector(this,
ctx,
true));
}
@Override
public RequestCycle newRequestCycle ( Request request, Response
response )
{
return new HibernateRequestCycle(this, (WebRequest) request,
(WebResponse)
response);
}
our session per RequestCycle Implemenatation:
=========================
public class HibernateRequestCycle extends WebRequestCycle
{
SessionFactory sessionFactory;
public HibernateRequestCycle ( JlotApplication application, WebRequest
request, Response response )
{
super(application, request, response);
this.sessionFactory = (SessionFactory)
application.getApplicationContext().getBean("sessionFactory");
}
@Override
protected void onBeginRequest ( )
{
if
(!TransactionSynchronizationManager.hasResource(sessionFactory))
{
Session session =
SessionFactoryUtils.getSession(sessionFactory, true);
TransactionSynchronizationManager.bindResource(sessionFactory, new
SessionHolder(session));
}
super.onBeginRequest();
}
@Override
protected void onEndRequest ( )
{
SessionHolder sessionHolder = (SessionHolder)
TransactionSynchronizationManager.unbindResource(sessionFactory);
SessionFactoryUtils.closeSession(sessionHolder.getSession());
super.onEndRequest();
}
}
wherever you need a Spring bean you can inject it like this:
@SpringBean
Repository repository;
public MyClass()
{
InjectorHolder.getInjector().inject(this);
}
if you have a wicket component you do not need this line:
InjectorHolder.getInjector().inject(this);
then read about detachable Models! Its quite important to understand it if you
use hibernate.
we use an entityModel like this one:
http://wicketinaction.com/2008/09/building-a-smart-entitymodel/
if you like i can send you more source code, but i got it working just by
reading "wicket in action", which is am excellent book.
our software will be open source soon, so i can send you the complete source
code if you like.
kind regards
Janning
