In this detailed Resource page, we feature an abundance of Hibernate Tutorials!
 
Hibernate ORM (Hibernate in short) is an object-relational mapping tool for the Java programming language. It provides a framework for mapping an object-oriented domain model to a relational database. Hibernate handles object-relational impedance mismatch problems by replacing direct, persistent database accesses with high-level object handling functions.
 
Hibernate’s primary feature is mapping from Java classes to database tables, and mapping from Java data types to SQL data types. Hibernate also provides data query and retrieval facilities. It generates SQL calls and relieves the developer from the manual handling and object conversion of the result set.
 
The mapping of Java classes to database tables is implemented by the configuration of an XML file or by using Java Annotations. When using an XML file, Hibernate can generate skeleton source code for the persistence classes. This is auxiliary when annotations are used. Hibernate can use the XML file or the Java annotations to maintain the database schema.
 
There are provided facilities to arrange one-to-many and many-to-many relationships between classes. In addition to managing associations between objects, Hibernate can also manage reflexive associations wherein an object has a one-to-many relationship with other instances of the class type.

Hibernate Tutorials – Getting Started

Simple examples on how to download and use Hibernate so that you can develop your own Hibernate based applications

  • Hibernate Tutorial For Beginners with Examples
    Hibernate is a high performance Object/Relational mapping (ORM) framework completely used in Java. Hibernate also provides query service along with persistence. This gives developers a way to map the object structures in Java classes to relational database tables.
  • Hibernate Best Practices Tutorial
    Hibernate is by far the most popular JPA implementation. This popularity brings several advantages for all users. There are lots blog posts about it, questions and answers on popular forums and well-established best practices.
  • Eclipse Hibernate Tools plugin Tutorial
    In this example, we will learn to install the Hibernate tools plugin for eclipse. Further, we will look at the features available through the plugin, which ease development using hibernate ORM within eclipse.
  • Hibernate Example Directory Structure
    In this tutorial we will show how to setup a Hibernate project with Eclipse.
  • Hibernate Configuration File Tutorial
    In this example, we will show how to configure hibernate. Hibernate requires to know in advance where to find all the mapping information related to java classes and database tables. There are some other database related settings that hibernate needs which are provided through configuration file.
  • Hibernate JPA DAO Example
    This is an example of how to create Data Access Objects (DAOs), making use of the Hibernate implementation for the Java Persistence API (JPA) specification.
  • Hibernate Query Language Example
    In this example we are going to see how to use Hibernate Query Language (HQL). This the query language created for Hibernate. It’s syntax is very similar to a normal SQL language but instead of tables it deals with classes and instead of columns it deals with properties or class attributes.

Hibernate Tutorials – Functions

Learn the most famous functionalities and operations of the Hibernate Framework

    A CRUD operation deals with creating, retrieving, updating, and deleting records from the table. In this tutorial we will see how it is done using Hibernate annotations. We are going to discuss 4 main functionalities: Creating a Record, Displaying Records, Updating a Record, Deleting a Record.
  • Hibernate Named Query Example
    When working with Hibernate and Hibernate HQL, you will find yourself writing again and again the same tedious queries. Not only that, but most of the times these queries are scattered throughout your code making it very hard too read and even harder to maintain.
  • Hibernate Join Example
    Join statements are used when one wants to fetch data from multiple tables of database. Hibernate provides support for join statements where one can write single query to fetch data from multiple tables easily. Hibernate is one of the few JPA (Java Persistence API) providers.
  • Hibernate Insert Example
    In this example, we will show how to use hibernate to insert data into database. Hibernate is one of the few JPA (Java Persistence API) provider. Hibernate is extensively used for persistence layer of building a enterprise application.
  • Hibernate Foreign Key Example
    Foreign key refers to single column or group of columns in table that link data present in another table through its primary key. A Foreign key can’t exist without its parent key but viceversa is not true.

    In simple terms, a One-to-One Association is similar to Many-to-One association with a difference that the column will be set as unique i.e. Two entities are said to be in a One-to-One relationship if one entity has only one occurrence in the other entity.
  • Hibernate One to Many Example
    One-to-Many mapping means that one row in a table can be mapped to multiple rows in another table but multiple rows can be associated with only one instance of the first entity. It is 1-to-n relationship.
