Hibernate Tutorials, Tips & Tricks
Hibernate is an object-relational mapping (ORM) library for the Java language, providing a framework for mapping an object-oriented domain model to a traditional relational database. Hibernate solves object-relational impedance mismatch problems by replacing direct persistence-related database accesses with high-level object handling functions.
Hibernate is free software that is distributed under the GNU Lesser General Public License.
Hibernate’s primary feature is mapping from Java classes to database tables (and from Java data types to SQL data types). Hibernate also provides data query and retrieval facilities. Hibernate generates the SQL calls and attempts to relieve the developer from manual result set handling and object conversion and keep the application portable to all supported SQL databases with little performance overhead.
Let us understand how One-to-one relationship is implemented in Hibernate using Annotations. For this we will use our previous article
One-to-one mapping in Hibernate using XML mapping and enhance it to support Annotations.Tools and Technologies used in this article:Java JDK 1.5 above MySQL 5 above Eclipse 3.2 above Hibernate 3 above Maven 3 above1. Database with One-to-one relationship tables We will use the same tables we created in our ...
Let us understand how One-to-one mapping works in Hibernate. Following is a simply yet concept building example where we will understand One-to-one mapping in Hibernate framework using XML Mappings. We will use two tables "employee" and "employeedetail" which exhibits one-to-one relationship. Using Hibernate we will implement this relationship.Tools and technologies used in this article:Java JDK 1.5 above MySQL 5 above Eclipse 3.2 above Hibernate 3 above Maven 3 ...
In this tutorial we will write a CRUD application in Hibernate using Java 5 Annotation. For this we will use our previous tutorial
Hibernate Maven MySQL hello world example (XML Mapping) as base and convert it from XML Mapping to Annotation.Tools and Technologies used:Java JDK 5 or above Eclipse IDE 3.2 or above Maven 3.0 or above Hibernate 3.0 or above MySQL 5.0 or above1. Database CreationFor ...
In this tutorial, we will try to write a small hello world program using Hibernate, MySQL and Maven. We will create a Java project using Maven and will then try to add Hibernate on it.Following are the tools and technologies used in this project.Java JDK 5 or above Eclipse IDE 3.2 or above Maven 3.0 or above Hibernate 3.0 or above MySQL 5.0 or above1. Database CreationFor this tutorial, ...
Hibernate was started in 2001 by Gavin King as an alternative to using EJB2-style entity beans. Its mission back then was to simply offer better persistence capabilities than offered by EJB2 by simplifying the complexities and allowing for missing features.Early in 2003, the Hibernate development team began Hibernate2 releases which offered many significant improvements over the first release.JBoss, Inc. (now part of Red Hat) later ...
Working with BLOB / CLOB data types in database is sometime a trivial task. I found particularly when working with Hibernate 3 to store and retrieve BLOB objects we need certain things to be taken care of. Let us see a tutorial where we will using Spring 3 MVC and Hibernate 3 to store and retrieve ...
Let us make a complete end-to-end application using Spring 3.0 MVC as front end technology and Hibernate as backend ORM technology. For this application we will also use Maven for build and dependency management and MySQL as database to persist the data.The application will be a simple Contact Manager app which will allow user to add new contacts. The list of contacts will ...
This is an attempt to create a simple URL shortner service in pure JEE with Struts2 and Hibernate.Creating Base Framework I always have Basic framework ready which gives a kick start to the web app development. You don't have to hassle about different configuration issues/jar file issues etc. Let us start with creating sample base framework ...
This is a demo Contact Manager application that we will create using Struts2 and Hibernate framework. In this article we will see how we can use Hibernate to perform Insert / Delete operations in Struts2 framework.Our Goal Our goal will be to demonstrate the use of Struts2 with Hibernate framework and to create a demo application "Contact Manager". The basic requirement of the Contact Manager app ...
