The technique of bridging the gap between the object model and the relational model is known as object-relational mapping, or O-R mapping or simply ORM.

Each of these properties is represented by a pair of accessor methods to get and set the property, and is backed by a member field.

To turn Employee into an entity, we first annotate the class with @Entity . It is a marker annotation to indicate to the persistence engine that the class is an entity.

Spring Data JPA, part of the larger Spring Data family, makes it easy to easily implement JPA based repositories. This module deals with enhanced support for JPA based data access layers. It makes it easier to build Spring-powered applications that use data access technologies.

Implementing a data access layer of an application has been cumbersome for quite a while. Too much boilerplate code has to be written to execute simple queries as well as perform pagination, and auditing. Spring Data JPA aims to significantly improve the implementation of data access layers by reducing the effort to the amount that’s actually needed. As a developer you write your repository interfaces, including custom finder methods, and Spring will provide the implementation automatically.

The recommended way to get started using spring-data-jpa in your project is with a dependency management system – the snippet below can be copied and pasted into your build. Need help? See our getting started guides on building with Maven and Gradle .

In this tutorial you will become familiar with the basic tools and development processes under OpenJPA by creating a simple JPA application.

Imagine that you have decided to create a software toolkit to be used by pet shop operators. This toolkit must provide a number of solutions to common problems encountered at pet shops. Industry analysts indicate that the three most desired features are inventory maintenance, inventory growth simulation, and behavioral analysis. Not one to question the sage advice of experts, you choose to attack these three problems first.

According to the aforementioned experts, most pet shops focus on three types of animals only: dogs, rabbits, and snakes. This ontology suggests the following class hierarchy:

This is the first part of tutorial about using Hibernate and JPA. This part is an introduction to to JPA and Hibernate. The second part will look at putting together a Spring MVC application using Spring ORM to reduce the amount of code necessary to create a CRUD application.

Additionally we'll want JUnit for creating tests and Tomcat so we can using it's JNDI naming for tests. JNDI is a preferable system to including the server details in a properties file for reasons we'll come to.

The key config file for JPA is persistence.xml. This lives in the META-INF directory. It details what the persistence driver to use and what JNDI data source to connect to. Additional properties can also be specified, in this case we'll include some Hibernate properties.
