Hibernate ORM Tutorial

A minimal Java project demonstrating how to connect to a MySQL database using Hibernate ORM.
The sample code shows how to create a SessionFactory, persist a User entity, and cleanly shut down the session.

---

Prerequisites

• JDK 8+
• Apache Maven
• MySQL server with a database named HibernateDB

---

Setup

1. Clone the repository

   git clone https://github.com/PapeMarc/Vortrag_Hibernate-ORM.git
   cd Vortrag_Hibernate-ORM

2. Configure database credentials
   Edit src/main/resources/hibernate.cfg.xml and insert your MySQL password:

   <property name="connection.password">{INSERT PASSWORD HERE}</property>

3. Prepare the database
   Ensure that HibernateDB exists and contains a table user with columns:

   • id (INT, auto-increment, primary key)
   • fullname (VARCHAR)
   • pass (VARCHAR)

---

Build

mvn clean compile

---

Run

Execute the Main class (via your IDE or the command line). The sample Main program:

DatabaseAccess db = new DatabaseAccess();
db.createFactory();
db.createUser("Tim", "TimSeinSehrSicheresPasswort,!");
db.disposeFactory();

This sequence opens a session, inserts a new User record, and closes the session factory.
