data persistence using hibernate
Hi,
can anyone direct me to any resources on how to integrate hibernate for
data persistence?
the closest I've managed to find is
https://www.infoworld.com/article/2077901/web-development-with-wicket--part-3--many-ways-to-persist.html?page=7
but there's still things that are confusing me on how to ingrate an
authenticated application with hibernate

HikariCP is a just a connection pool.
I am not sure what exactly you mean with "instead". A connection pool is
not a replacement of an ORM framework like Hibernate.
However, I can't workout where the most appropriate place to put the
connection pool close call, is there a close or shutdown function
I can override so that the connection pool can be closed cleanly. I
haven't had any luck in my search so far
Additionally, I keep running into the following error:

Could not load [META-INF/services/org.mariadb.jdbc.plugin.Codec].
The following stack trace is thrown for debugging purposes as well as to
attempt to terminate the thread which caused the illegal access.
I'm assuming this is a error more to do hikaricp so I'll enquire among
their community about it, but if someone has encountered this before feel

still seem to be able to send queries to the database from what I can

This is done in some utility method when you retrieve the session for
the first time in the request.
You should also check if the session is already bound by calling
ManagedSessionContext.hasBind(SessionFactory factory)
and binding it only once per request.
unbindSessionFactory
I have this in my custom implementation of
IRequestCycleListener.onEndRequest(RequestCycle cycle)
that you add in Application.init() method
getRequestCycleListeners().add(new DataRequestCycleListener());

Thank you for the help so far both of you, I've probably made
mistakes with implement parts
of the previously outlined process.
I've come from experimenting with javafx so wicket has been a radical
change of direction for me
so far. But since there is very little in the way of examples for
database integration I'm struggling
to get my head around how to implement it correctly, as well as
knowing for sure whether I've

Re: data persistence using hibernate
Posted by James Pollard <ja...@iinet.net.au>.
I've managed to make some progress with database connectivity, ended up
using hikaricp instead
However, I can't workout where the most appropriate place to put the
connection pool close call, is there a close or shutdown function
I can override so that the connection pool can be closed cleanly. I
haven't had any luck in my search so far
Additionally, I keep running into the following error:
java.lang.IllegalStateException: Illegal access: this web
application instance has been stopped already.
Could not load [META-INF/services/org.mariadb.jdbc.plugin.Codec].
The following stack trace is thrown for debugging purposes as well as to
attempt to terminate the thread which caused the illegal access.
I'm assuming this is a error more to do hikaricp so I'll enquire among
their community about it, but if someone has encountered this before feel
to volunteer any suggestions or recommended actions. The odd thing is I
still seem to be able to send queries to the database from what I can
tell

This is done in some utility method when you retrieve the session for
the first time in the request.
You should also check if the session is already bound by calling
ManagedSessionContext.hasBind(SessionFactory factory)
and binding it only once per request.

I have this in my custom implementation of
IRequestCycleListener.onEndRequest(RequestCycle cycle)
that you add in Application.init() method
getRequestCycleListeners().add(new DataRequestCycleListener());
To be honest, I've until now stayed away from Spring as it still seems
to me as a too much of a black box that I didn't find a time to invest
in learning it, so I may not be the right person to give you advice,
because my solution may not be the best one either, although it seems to
be as javadoc of the ManagedSessionContext suggests. The solution I now
use took heavy inspiration in old old, now nonexistent, Databinder that
came around the time Wicket 1.2 or so and when I was tasked to select
new java framework after landing my first job and found Wicket. Old
times :D.

Re: data persistence using hibernate
Posted by James Pollard <ja...@iinet.net.au>.
Thanks Vit,
I've defined the hibernate.cfg.xml file
I've defined the following globally in the Application class
private Configuration config = new Configuration();
private ServiceRegistry serviceRegistry;
private SessionFactory sessionFactory;
I've placed the following at the end of the init function
config.configure("hibernate.cfg.xml");
config.setProperty("hibernate.current_session_context_class", "managed");
serviceRegistry = new
StandardServiceRegistryBuilder().applySettings(config.getProperties()).build();
sessionFactory = config.buildSessionFactory(serviceRegistry);
But I'm not sure where to put the following parts
Session sess = sessionFactory.openSession();
ManagedSessionContext.bind(sess);
unbindSessionFactory
Thank you for the help so far both of you, I've probably made mistakes
with implement parts
of the previously outlined process.
I've come from experimenting with javafx so wicket has been a radical
change of direction for me
so far. But since there is very little in the way of examples for
database integration I'm struggling
to get my head around how to implement it correctly, as well as knowing
for sure whether I've
done it correctly
Best Regards

This is true. I have used Hibernate/JPA without the SpringBoot parts... But
those projects are private: some owned by me, others no.

Re: data persistence using hibernate
Posted by Vit Rozkovec <ro...@email.cz>.
Hi,
I'm currently using Hibernate without Spring and what you want to
achieve can be done in several steps:
- prepare your org.hibernate.cfg.Configuration
- set Configuration's property:
config.setProperty("hibernate.current_session_context_class", "managed");
- get SessionFactory by caling org.hibernate.cfg.Configuration.build()
- store SessionFactory's instance somewhere and keep it for the duration
of your application
- when you request a session, bind it:
Session sess = sessionFactory.openSession();
ManagedSessionContext.bind(sess);
- at the end of request cycle, unbind SessionFactory. Implement your own
IRequestCycleListener and in IRequestCycleListener.onEndRequest call
unbind logic.
Here's what I use:
public void unbindSessionFactory(Object key, boolean closeSessionFactory)
{
SessionFactory sf = getHibernateSessionFactory(key);
if (hasBoundSession(sf))
{
Session sess = sf.getCurrentSession();
if (sess.isOpen())
{
try
{
if (sess.getTransaction().isActive())
{
sess.getTransaction().rollback();
}
}
finally
{
sess.close();
}
}
ManagedSessionContext.unbind(sf);
if (closeSessionFactory)
sf.close();
}
}
- when application exits, close session factory
Hope that helped.

Re: data persistence using hibernate
Posted by James <ja...@iinet.net.au>.
Thanks for the guidance so far, that pointed me to find additional
resources on JPA
I believe I have this configured correctly, but I'm confused about how
to integrate JPA/Hibernate into a
pure wicket authenticated web application project since the resource you
directed me to previously
seems to be more heavily on the spring side of things.
Thank you for accommodating all my questions and misunderstandings so
far, I tend to use a reverse
engineer learning style so it's helped me immensely.
I've included screenshots of the project file list and the application
class in the hopes that it makes
understanding what I'm trying to convey easier

https://github.com/MarcGiffing/wicket-spring-boot/blob/master/wicket-spring-boot-starter-example/src/main/java/com/giffing/wicket/spring/boot/example/model/Customer.java
This defines a JPA entity.... and this JPA/Hibernate
https://github.com/MarcGiffing/wicket-spring-boot/blob/master/wicket-spring-boot-starter-example/src/main/resources/application.yml
Project uses Spring magic I guess and will start a Hibernate with H2.
Wicket is also started via SpringBoot.

I've had a look through it but couldn't find any reference to hibernate
so far, its entirely
possible that I managed to miss it while I was searching though

Hi,
This project

contains a sample project that integrates with JPA/hibernate.
