Hibernate Mapping One-to-One using Annotations

Learn how to do one-to-one mapping using hibernate annotations.
Welcome to Hibernate Tutorial Series. In previous tutorials we saw how to implement Relationship Mapping in Hibernate. We saw different mapping techniques like One to Many, Many to Many using both Annotations and XML mapping. Today we will see how the Inheritance is managed in Hibernate. You may want to look at previous tutorials. Here is the complete list for you.

Hibernate 3 introduction and writing hello world application
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. Hibernate used its mapping files and configuration files to achieve its objectives. With the introduction of annotations in java community with JDK 1.5, Hibernate community started working on Hibernate 3, which has support for annotations.

Hibernate one-to-one mapping using annotations
If you are working on any hibernate project or you are planning to work on any in future, then you can easily understand the one-to-one relationships between several entities in your application. In this post, i will discuss variations of one-to-one mappings supported in hibernate.


Hibernate many-to-many mapping using annotations
Many to many mapping is made between two entities where one can have relation with multiple other entity instances. For example, for a subscription service SubscriptionEntity and ReaderEntity can be two type of entities. Any subscription can have multiple readers, where a reader can subscribe to multiple subscriptions. In this post, we will learn to make such mapping in database using hibernate 3.


Hibernate one-to-many mapping using annotations
One to many mapping is made between two entities where first entity can have relation with multiple second entity instances but second can be associated with only one instance of first entity. Its 1 to n relationship. For example, in any company an employee can register multiple bank accounts but one bank account will be associated with one and only one employee. In this post, we will learn to make such mapping in database using hibernate 3.

Hibernate 4 example to get entity reference for lazy loading
By Wikipedia definition, Lazy loading is a design pattern commonly used in computer programming to defer initialization of an object until the point at which it is needed. We know that in hibernate lazy loading can be done by specifying “fetch= FetchType.LAZY” in hibernate mapping annotations.

Hibernate insert query tutorial
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. This means you are not required to build and execute SQL queries for interaction with database. You just have to instruct hibernate for that by calling hibernate APIs and hibernate will create and execute those SQL queries on behalf of you. In this tutorial, I am giving example of inserting data in a single table. We have an object in application i.e. Employee. We want to store it in database. It has following attributes...

JPA Tutorial
JPA is the new Hibernate-like persistence specification that has become part of the Java EE 5 spec itself. JPA uses Java 5 annotations to control how plain Java classes (POJOs) get mapped to database tables. The MyEclipse tooling for JPA offers powerful generation and automation in the form of mapping existing DB tables directly to generated POJOs that are ready to be used against that database. MyEclipse also offers additional features for JPA in the Java source editor with reference to the annotations used to annotate the entities. MyEclipse will provide validation and autocomplete against the DB resources that the POJOs are referencing.

Developing Applications with JBoss and Hibernate
Developers will be introduced to Hibernate and learn to build Java classes and map files from scratch. They will also learn to reverse engineer the database schema into Java classes and Hibernate mapping files and build a web application that will be able to interact with the Hibernate POJOs which they will later deploy to JBoss AS.

Metadata annotations
In this first article I'll explain the purpose of metadata and demonstrate how to use metadata annotations provided in the core J2SE libraries.
In the second article, I'll show how to write your own annotations (first writing simple ones like @Copyright and then looking at more advanced annotations like those built into the core language).
In the third article, I'll demonstrate how tools can use annotations at build-time (generating new source or supporting files) and how programs can use annotations at runtime (to change code behavior).
