We Keep Coding

I am using hibernate, no pom.xml or maven and getting the error?

This is my main class
package com.luv2code.hibernate.demo;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class CreateStudentDemo {
public static void main(String[] args) {
// create session factory
SessionFactory factory = new Configuration().configure("hibernate.cfg.xml").addAnnotatedClass(Student.class).buildSessionFactory();
// create session
Session session = factory.getCurrentSession();
try {
// create stydent object
System.out.println("Creating a new student object");
Student tempStudent = new Student("Paul", "Wall", "paulWall#gmail.com");
// start a transaction
session.beginTransaction();
// save student object
System.out.println("Saving student ");
session.save(tempStudent);
// commit the transaction
session.getTransaction().commit();
System.out.println("Done ...");
}
catch (Exception e) {
System.out.println("ERROOOOORRR");
}finally {
((SessionFactory) factory).close();
}
}
}
This is my hibernate configuration file

Hibernate - persist automatically each relation

Maybe it is a simple question, but I can't find out this situation of relations in Hibernate.
I have these Entities:
#Entity
public class User {
...
#OneToMany(mappedBy = "user")
private Set<Conversation> posts = new HashSet<Conversation>();
...
}
#Entity
public class Conversation {
...
#OneToMany(mappedBy = "conversation")
private Set<Message> messages = new HashSet<Message>();
...
}
#Entity
public class Message { ... }
and then I want create User with Conversation and Message at once. Idea should be like this:
User user = new User();
user.getPosts().add(new Conversation(){
{
getMessages().add(new Message());
}
});
session.persist(user);
But just User is saved in database - why isn't it all? Because of default LAZY fetching? Could my idea be implemented somehow?
PS: Of course I know about the solution of persisting each of the entities, but I am used to do like this in other frameworks like nette or Django, so I can't get out of my head.
PPS: I found out that problem is in default CascadeType. Could it be set on globally, e.g. in Hibernate config XML? Is it a good idea (by performance point of view - it is persisted each time on "superpersist" or only in case of changes)?
PPPS: I also found out (opposite to Django) that I have to set FK ex-post for each item added to collection. It is natural (because of selected pure Set type), but new for me. Which approach would you recommend me? Required FK as argument in constructor on item Entity e.g.:
Class Message{
Message(Conversation conversation){
setConversation(conversation);
}
...
}
or make a method for adding where FK sets inside e.g.:
Class Conversation{
...
public void addMessage(Message msg){
msg.setConversation(this);
getMessages().add(msg);
}
...
}
?
Making Session + configure XML.

private static SessionFactory sessionFactory;
private static ServiceRegistry buildRegistry() {
return new StandardServiceRegistryBuilder()

}
private static Metadata getMetaData() {
return new MetadataSources(buildRegistry()).getMetadataBuilder().build();
}
private static SessionFactory buildSessionFactory() {
return getMetaData().getSessionFactoryBuilder().build();
}
public static SessionFactory getSessionFactory() {
if (sessionFactory == null) {
sessionFactory = buildSessionFactory();
}
return sessionFactory;
}
public static Session getSession(){
try {
return getSessionFactory().openSession();
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
and the hibernate-cfg.xml

<mapping class="learnme.hibernate.entities.User"/>
<mapping class="learnme.hibernate.entities.Conversation"/>
<mapping class="learnme.hibernate.entities.Message"/>
</session-factory>
</hibernate-configuration>

According to this and this
you need to have this in your persistence.xml file to set it globally:
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm
http://java.sun.com/xml/ns/persistence/orm_1_0.xsd" version="1.0">
<persistence-unit-metadata>
<persistence-unit-defaults>
<cascade-persist/>
</persistence-unit-defaults>
</persistence-unit-metadata>
</entity-mappings>
The mapping file has to be located either in the default location,
META-INF/orm.xml, or in another location that is specified explicitly
in the persistence unit definition (in persistence.xml).

Main Class : src\dao\Index.java

As you are NOT using the Hibernate bean annoatations, in your Hibernate.cfg.xml file, you need to change <mapping class ="Emp.hbm.xml" /> to <mapping resource ="Emp.hbm.xml" />
Hibernate is an ORM framework which maps the Java Bean to a Relational database table and the mapping can be provided directly in the Java Bean Object (using Annotations) or can be provided separately through xml files (like how you did).
Hibernate SessionFactory mappings are compiled from various XML mapping files and <mapping resource is used to load those mapping files (in your case it is a single file which is Emp.hbm.xml file)
You can refer the below documentation for more details:
https://docs.jboss.org/hibernate/core/3.3/reference/en/html/session-configuration.html

It looks like it may be an error in your connection URL. Shouldn't it be
jdbc:postgresql://localhost:5432/hibernatedb
?

Check your connection URL path it should be like this:
<property name="connection.url">jdbc:postgresql://localhost:5432/hibernatedb</property>
If this doesn't work then note that in PostgreSQL's case it's typical to use port 5432 if it is available. If it isn't, most installers will choose the next free port, usually 5433. So you may enter the property like this
<property name="connection.url">jdbc:postgresql://localhost:5433/hibernatedb</property>
If you still can't figure out then read this line in your stacktrace you may get the idea what #RemyG is trying to say:
org.postgresql.util.PSQLException: FATAL: database "5432/hibernatedb" does not exist at
